bloganother year will soon be past and, like many of you, we’re looking forward to next year. we’ll be taking some time the next few weeks to be with our families, and will be back in 2022 with more blogs, podcasts, product announcements, and ways for you to succeed with galaxy store and samsung platforms. with the end-of-year holidays upon us, we’re stopping to reflect on what we did in 2021. even with covid making a disruption in everyone’s lives, we’re still here to help developers find answers and hopefully, also find success. here are some of our most memorable moments. 10. developer portal refresh brought a modern look and support for mobile we’ve been working for several years to bring samsung’s developer portal into a single web infrastructure. we moved content from multiple servers and cloud services into a cms that uses open standards and a responsive design for mobile devices. we pored through a decade of content to make sure it was still timely and accurate for your needs today. we integrated the developer forums to use the same samsung account login for both the developer portal and seller portal to give you a more seamless experience. in october of this year, we made a ux refresh to the site and the most amazing thing is how easy that process went. there were no late nights in the weeks prior to launch. we were able to test the new ux in a sandbox rigorously. then the deployment to production happened almost instantaneously. we spent less time worrying about our website and more time creating the content you need to do your work. we understand how important the samsung developer portal is to you and your work. that’s why we took the time to ensure a smooth transition as we made major infrastructure changes. 9. monthly updates keep developers up-to-date on new galaxy store features the galaxy store product management team began publishing monthly newsletters to enlighten developers of the latest features and improvements to seller portal. these updates also usually appear as blog posts in the first week or two of the month. some of the major announcements include: staged app rollouts (october) local currencies in settlement and financial reports (september) private beta testing (july) galaxy store developer api (april) look for more exciting improvements in 2022 as galaxy store continues to innovate. 8. unpacked events bring exciting new product announcements galaxy unpacked in january 2021 brought announcements of the galaxy buds pro, galaxy s21, and the new galaxy smarttag. the event highlighted samsung’s design concepts with one ui 3 and integrated experiences from partners like microsoft and google. the august galaxy unpacked event brought announcements of galaxy z fold3 and galaxy z flip3 phones. these devices have many new hardware and software features for developers to build upon. this blog post highlighted many of the ways that developers can implement features supporting flex mode and s pen remote, while ensuring that users have a seamless experience with app continuity. the most anticipated announcement of the august galaxy unpacked event was the unveiling of galaxy watch4, featuring wear os, powered by samsung. as with the tizen-powered galaxy watch devices, samsung released a new tool, galaxy watch studio converter, to help existing designers bring their watch faces to wear os. designers could also start a new watch face project from scratch with the newly-released watch face studio tool. 7. remote test lab updates allow developers to experience the latest hardware as new devices are announced, developers can use the remote test lab (rtl) to ensure that their apps work properly on the new version of one ui as well as different screen resolutions and pixel densities. in 2021, the rtl development team added support for foldables and galaxy s21 devices, allowing developers to ensure their apps work correctly before the devices are available to consumers. the rtl team also added support for android studio. in september, thousands of devices were added in data centers around the world to ensure that a compatible device is always available. as part of this release, rtl was re-engineered to work exclusively in the chrome browser, so that no external software is needed to test apps on all the latest devices. 6. samsung developer forums activity the samsung developer forums, based on the popular open-source discourse project, were introduced in january 2020, replacing an aging forum infrastructure that didn’t work well on mobile devices. by using the same samsung account authentication method as the samsung developers site, we’re able to provide a nearly-seamless experience across different hosts and platforms. since their introduction, we’ve seen large numbers of visitors stop by the forums with questions. community manager ron liechty has more than 25 years of experience in managing healthy communities—his knowledge and guidance keeps the forums a useful resource for developers. some of these visitors have become our best community members, providing valuable feedback to their peers as well as helping to moderate spam and malicious content. 5. supporting game developers in 2021 games are a noticeable part of the galaxy store experience and we work with many partners and internal teams to ensure that gamers have a great experience on galaxy devices. the galaxy gamedev team works closely with some of the top publishers and developers to improve performance of top titles on mobile. this team creates tools that provide great detail on the performance of the cpu and gpu during intense moments of gameplay. the gamedev team then documents their efforts in a series of best practices and blog posts to help developers everywhere. in addition to our internal team work, we frequently work with our partners at arm to deliver relevant content for game developers. this summer, we published and promoted a number of educational articles, webinars, and training series in cooperation with the arm developer team. best practices for mobile game developers and artists new vulkan extensions for mobile: maintenance extensions new vulkan extensions for mobile: legacy support extensions new game changing vulkan extensions for mobile: descriptor indexing new game changing vulkan extensions for mobile: buffer device

gdc2021 event in july. gdc is an important event for all of us at samsung and we hope to see you all there at the live event in march 2022. 4. new voices appeared on samsung developers podcast, season 2 shortly before the covid-19 pandemic changed our lives, tony morelan from samsung developers attended a podcasting event and came back to the office inspired to start a podcast. he lined up guests from internal teams and important partners. everyone had a great time participating and it gave us a way to continue delivering quality content to developers. as 2020 turned to 2021, we continued bringing interesting guests from across the mobile design and development ecosystem. we used the podcast to talk about the upcoming virtual samsung developer conference and chat with the people that made the event a success. here are some of the highlights from season 2 of the samsung developers podcast: drazen stojcic, urarity – watch faces, design tan nguyen, butterfly-effected gmbh – galaxy themes, marketing, licensing the samsung internet advocacy team – web standards, privacy, foldable devices we’re still hoping for a return to days where we can travel and meet in person, but until that time comes, please join us in listening to these industry veterans and top developers on the samsung developers podcast. season 3 begins in early 2022. 3. blog series instructs readers on design and successful marketing without live events the past two years, we have searched for new ways to continue delivering timely and helpful advice to mobile app designers and developers. as mentioned previously, we worked with arm this year to bring great technical content front and center. we also worked with our network of top designers, developers, and thought leaders on concepts that will help you succeed on galaxy store and in creating better experiences for your users: better for all – in this blog series, we talked with leading designers and experts to help understand the increasingly important concepts behind the diversity, equality, and inclusion movement. this series discussed aspects of language used in apps, themes, and watch designs. it also highlights important guidelines to

success: understanding consumer trends strategies for success: building your fan base strategies for success: making your brand successful 2. best of galaxy store awards highlight successful developers the galaxy store app on your mobile device is more than just an app. behind the scenes, there is a team of developers, product managers, business leaders, and security experts devoted to ensuring the best possible online experience for consumers in 180 countries. because of their dedication, developers and designers have a great platform for monetizing their work. each year, the samsung developers team works with the galaxy store operations and business development teams to determine the best games, apps, and themes based on revenue, downloads, and impact to consumers. the result is the best of galaxy store awards. in 2018 and 2019, the best of galaxy store awards were presented live, on stage, at the samsung developer conference (sdc). without a live event in 2020 or 2021, the samsung developers team decided to continue the tradition of highlighting and awarding our top galaxy store products. even without an in-person event, we used a live premiere on youtube to have a single moment in time to celebrate with the winners. tony morelan emceed the event, but he had a lot of help from ron liechty, jeanne hsu, susie perez, and shelly wu. we thank them for their hard work. we hope you’ll enjoy watching! look for the “best of galaxy store” sash on apps, games, themes, and watch faces in galaxy store to know that you’re getting a truly unique experience. 1. discovering new opportunities at sdc21 each year, the samsung developer conference is the culmination of an incredible amount of planning and work by hundreds of people. even though the event was virtual in 2021, there was still a huge volume of work. instead of preparing for a live audience, our teams practiced in front of a galaxy phone on a tripod (really). instead of building booths and planning meals, we built a website and social media campaigns to reach a larger audience. eric cloninger and tony morelan kicked off the promotion for sdc21 with a podcast featuring a previous sdc speaker, chris shomo. before the conference, visitors were invited to create whimsical caricatures of themselves using the mysdcstack mini-site and submit their designs to social media. by participating in the event website, watching sessions, and trying the code labs, visitors would earn points toward a prize drawing after sdc. relive the experience of sdc21 by watching the keynote or any of the highlight sessions and technical talks by viewing this playlist wrapping up when sdc is finished, our team takes a collective deep breath, happy to be done. it is a satisfying experience to pull off a big industry event. we don’t know yet how we’ll handle live events, but we remain optimistic that some will occur. we are making plans and we hope we’ll be able to see you, somewhere, in 2022. 🤞 take care. stay warm (or cool). best wishes to you all and happy new year!

tutorials mobile, foldable
blogfoldable technology for mobile is a groundbreaking experience not only for users but also for developers. the presence of many form factors like immersive display, app continuity, flex mode and ux optimization challenge developers to think outside of the box to adapt to this technology. in this blog, we discuss a checklist to provide a better understanding about the adaptation, modification and design changes that are required. so, let's go through each point, one-by-one. large screen optimization samsung foldable devices have two different physical screens: the cover display and the main display. as the cover display is much smaller than the main display, large screen optimization is one of the key areas of designing ux for foldable devices. in a nutshell, your app can utilize the extra space in the main display by showing more information. just having a different ui design with the same information can do the trick of optimization as well. large screen optimization of a note app to implement this scenario, define different layout files for each display using the alternate resources option. for example, if you want to define a different ui for the main display, create a new directory named layout-sw600dp under the res directory and then create an xml file named activity_main. then add the layout code as required. ui is designed separately for the main display and the cover display flex mode optimization in galaxy z series devices, samsung introduced a new mode called flex mode. this mode allows users to use apps while the book-like phone is partially folded. creative design can really make your app stand out from others in flex mode. google duo app in flex mode in galaxy z series devices using google’s new jetpack library, windowmanager, you can detect the current posture of a galaxy z series device and update the ui accordingly by following these steps: step 1: add the dependencies in the build.gradle. implementation "androidx.window:window:1.0.0-alpha01" step 2: define a windowmanager instance. val windowmanager = windowmanager(this, null) step 3: register the devicestate change listener. the listener notices changes in the device state (for example closed, opened, half_opened). windowmanager.registerdevicestatechangecallback( mainthreadexecutor /* executor */, callback /* consumer<devicestate> */ ) step 4: write a callback function to check devicestate.posture to get the current posture of the device. if the posture is posture_half_opened, the app ui gets updated for flex mode. val callback = consumer<devicestate> { devicestate -> if (devicestate.posture == devicestate.posture_half_opened) { // display is folded, show split ux } else { // display is not folded, show full screen ux } } check out the codelab challenge on flex mode for a more hands-on experience. app continuity while folding and unfolding the device, the app must prevent data loss thus ensuring its continuity. this is achievable by using the onsaveinstancestate() method. first, save the data to retain the current state with onsaveinstancestate(). @override public void onsaveinstancestate(bundle savedinstancestate) { //save the current state } then, restore the data in the oncreate() function. @override protected void oncreate(bundle savedinstancestate) { if (savedinstancestate != null) { //restore the previous state } } stopwatch app continuity while unfolding device to have a better understanding of implementing app continuity, see the codelab challenge on app continuity. responsive ui layout to adapt to new form factors such as a diverse aspect ratio, flex mode, multi-window, and pop-up window, utilize the following guidelines : design a responsive ui layout for your app using constraintlayout. define the activity of your app as resizable, to ensure the maximum compatibility of your app with both the cover display and the main display of the device. set the resizableactivity attribute to true in manifest.xml. <activity android:name=".mainactivity" android:resizeableactivity="true"> … </activity> responsive layout of the spotify app cutout and punch hole of the main display the main display of a galaxy z fold is covered by an area on the top-right side called the “l-cut” whereas the galaxy z fold2 and fold3 have a punch hole in the upper right side and the galaxy z flip devices have a punch hole in the middle. some portion of your app’s ui could be covered by the l-cut or the punch hole. content is covered by the l-cut in a galaxy fold device in landscape mode to avoid such a scenario, depending on your ui content style, define a display cutout mode. for example, the content is letterboxed in landscape mode whereas it is rendered into the cutout area in portrait mode by default. define the display cutout mode in the style.xml as shortedges so that your content is rendered into the cutout area in both portrait and landscape modes. <item name="android:windowlayoutindisplaycutoutmode">shortedges</item> display cutout in the default mode and the shortedges mode, respectively last but not the least, you can test your app on our device cloud, samsung remote test lab, to make sure you have implemented all the checkpoints discussed in this blog. you can also participate in our codelab challenges to have a clear understanding of the implementation details. in this blog we have discussed about how to adapt your app for foldable devices. we hope it is a good guide for you to start with. you can also check out samsung’s official documentation and reach out to our developer community if you have any queries.

tutorials galaxy watch
blogas wearable technology becomes more mainstream, customized smartwatch faces can be an extension of users’ style and personality. with samsung’s watch face studio (wfs) tool, you can design custom watch faces for devices in the wear os smartwatch ecosystem, such as galaxy watch4 and newer smartwatches. after you have made your unique watch face, you can share it with a global audience by uploading it to the google play store. this article describes the basic steps to distribute your watch face through the google play store, such as registration, testing, and publication. to register your watch face in google play, you must have a google play developer account. create a watch face in wfs, design and create your watch face. the wfs interface allows you to easily add and customize watch face components and add theme colors to implement multiple color schemes, for example. as you create a watch face, you can preview it with the “preview” window in wfs or install it on your own smartwatch. if do not have access to a supported smartwatch, you can test your watch face in the remote test lab, which gives you remote access to a variety of samsung galaxy watch devices. because smartwatches have limited hardware, you must be mindful of the amount of memory used by the watch face. the watch face specification defined by google has memory usage limits. to avoid issues related to these memory usage policies, wfs versions 1.6.9 beta and higher support a memory usage plugin that easily estimates the memory use of your watch face. notethe results from the plugin are not guaranteed to match the actual memory capacity check results from google play. figure 1: memory usage plugin prepare screenshots use the “preview” window in wfs to capture screenshots of your watch face in various sizes. you need these to register your watch face in google play. to create watch face screenshots: in the “preview” window, set the watch face to show the screen you want to capture. open the dropdown menu next to the camera icon and select the screenshots you want to create. click the camera icon. the screenshots are saved in the “screenshots” folder within your project folder. figure 2: screenshot creation generate the watch face package watch face projects are bundled into package files for publication. the google play store requires an aab file, while the galaxy store (for china only) requires an apk file. you can generate either or both in wfs: in the wfs project screen, select publish. define the unique package name, location for the generated file, version name and code, and package type. by default, the generated file is located in your project folder: “c:\users\username\watchfacestudio\build\project_name\” (windows) or “/users/username/watchfacestudio/build/project_name/” (macos). figure 3: watch face file generation you must also have a valid keystore used to sign the package file: if you have previously created a keystore, enter its information. if you do not have a keystore, select create new key. in the “new keystore” dialog, define the required details and click ok. figure 4: keystore creation when you are ready to generate the watch face package, in the “publish” dialog, click ok. noteremember that the key alias password and the keystore password must be identical. a warning dialog pops up if you use different passwords. register the watch face to register your watch face application in google play, sign in to your google play developer account. in the google play console, select all apps > create app and fill in the required information, such as the name, default language, and if the watch face is to be free or paid. you must also include any necessary disclosures. you can modify this information later, as needed. test the watch face before your watch face can be made available to the public, you must test it with actual users. testing, internal (recommended) and closed (required), ensures that your watch face behaves according to your design and complies with google play content policies and quality guidelines. for information about the google play content policies and application quality guidelines, see prepare your app for review and wear os app quality. you can easily monitor the testing status, number of installations and users, update status, and more for your applications through the google play dashboard. internal testing you can quickly distribute your builds to a limited number of trusted testers for their feedback. while internal testing is optional, it is strongly recommended. to set up your watch face for internal testing: in the google play console, select view app for the watch face that you want to test. its dashboard page opens. from the side menu, select testing > internal testing. since you have developed a watch face, you must select the wear os form factor. open the dropdown menu next to “create new release” and select manage form factors. in the “form factors” section, add wear os. figure 5: form factor selection unfold the “view tasks” list in the “set up internal testing track” section. the list guides you through the test setup process. for example: completing application setup in google play, such as defining the name and description to be displayed in the google play store uploading the required images for the google play store, such as its icon, screenshots, and feature graphics defining up to 100 internal testers for your application; the list can be modified later, as needed in the "create a new release" task: a. upload the aab file you want to test. you are prompted to sign the file by selecting or creating a signing key. b. name the release and add an optional release note. select preview and confirm the release. google play automatically checks for possible issues, such as missing information. to resolve the issues, follow the instructions for each list item. figure 6: issues list when you are ready to start the test, select start rollout to internal testing. distribute the test link or email invitations to your testers. the test link can take a few hours to become available. closed testing you can get targeted feedback from a wider group of users that you select, without affecting your public ratings and reviews. closed testing also sends your application to google to check for policy compliance before distributing it to your testers. noteif you have a personal google play developer account created after november 13, 2023, you need at least 20 testers to participate in your application’s closed test for a minimum of 14 days before you can apply for access to production. setting up a closed test is similar to setting up an internal test: in your watch face’s dashboard page in the google play console, go to testing > closed testing. to create a closed testing track, select create track and define a name for the testing track. open the dropdown menu next to “create new release” and select wear os only. complete the tasks in the “set up closed testing track” section, such as defining the countries where the application is to be available and the list of testers. figure 7: closed testing setup in the “create a new release” task, select an application package file that you have previously uploaded, or upload a new one. name the release and add an optional release note. select preview and confirm the release and resolve any detected issues. select send the release to google for review. when the release is approved, you can share the testing link with your testers. for more information on creating and managing tests, see set up an open, closed, or internal test. publish the watch face when you have completed closed testing and your watch face is ready to publish, apply for access to production. when access is approved, the watch face is available publicly in the google play store. summary it is easy to transform your watch face concept from design to published product. create the watch face with watch face studio, register it in the google play console and conduct user tests, then publish it in the google play store to share it with the world. if you have questions or need help with the steps presented in this article, you can share your queries on the samsung developers forum. you can also contact us directly for more specialized support through the samsung developer support portal.

blogspring is here and it’s a good time to clean house in your digital world. from your design process to galaxy store presence, it’s important to think about changes that could make things more efficient. to help you get started, members of the samsung developers community have been sharing advice on how they’ve successfully refined their processes and their galaxy store presence. we continue our series with tan nguyen from butterfly-effected, gmbh. a themes and watch faces designer, butterfly-effected has a long history with samsung, having provided content for our first mobile content store, the samsung funclub. read on to learn about tan’s process for quality control that allows him to grow, while keeping their designs fresh. how did you get into designing themes and watch faces? since 2006, we’ve been working with samsung in different areas. for the uefa euro 2016 football championship, samsung planned a promotion and asked us if we could create some themes for them. we were amazed at the number of downloads and created more. after seeing amazing results again, we continued designing more. that´s basically how everything started. has your design approach evolved over time? our process begins with collecting ideas, sketching and then selecting the best ones for production. then we do extensive q&a on the design and the technical part (e.g. are the colors visible in all combinations?). if everything passes, we send them to our partners for their approval before we upload them to the store. in the past, we spent a lot of time on the technical part, because everything was new. now we have more experience and the tools have matured, so we can focus more on the creative part and design. the samsung galaxy themes studio editor has an integrated visibility check that is a helpful tool when finalizing designs. geometric perspective by butterfly-effected, gmbh do you have a system in place to organize your designs and the way you present them? we created our own system to keep track of all the designs, designers, tasks, sales and revenue share for our brands. in addition to galaxy store, we use social media, mainly facebook, to present new products to customers and fans. how often do you revisit your old designs and update them? we take the most downloaded designs (even the free ones) and update them on a regular basis. time is allocated for that, and we update as many as possible without affecting the production of new themes. some themes have more sales after the update, others do not. but in general, there is an increase, so it makes sense to revisit older designs — especially since products without an update tend to experience a drop in sales. black fiber by butterfly-effected, gmbh when new platforms are released, do you check to make sure all designs are working? when a new platform is released, there are usually many different firmware versions. this can make the creation and the q&a process quite complex if the tester’s firmware, remote test lab (rtl) and our phones show different things. we always prioritize checking on products with higher downloads. we use rtl when new issues arise (e.g. color combinations) that we can´t reproduce or fix in galaxy themes studio. what advice would you give a designer about organizing and maintaining their work? backup all source files and keep a file with all the layers. also, it is helpful to use version control software to not lose track of supported devices and firmware. thanks to tan for sharing helpful advice on improving the q&a process and prioritizing updates to keep designs fresh. you can connect with tan and butterfly-effected, gmbh on their facebook themes page and facebook watch faces page. you can also check out butterfly-effected’s full collection of designs in galaxy store. we hope this post helps you start your spring refresh for success. remember, making galaxy store updates is key to keeping your seller account active. you need two activities every three months that trigger an app review by the seller portal team. an activity takes many forms, and can be anything from uploading a new app, to updating a current app, or changing the description or adding/updating photos. however, changing the price of an app does not count. stay tuned next week for the final installment in our ‘refresh for success’ series and follow us on twitter at @samsung_dev for our latest updates.

} this means that the game engine will use the upl file if the platform is android otherwise, the foldablehelper won’t work implement a storage struct the next thing to implement is a struct, the native version of java’s foldablelayoutinfo class to store the data retrieved from the java code using a struct, do the following in content browser of unreal editor, right-click on c++ classes > add/import content then, click new c++ class select none for the parent class and click next name the new class as foldablelayoutinfo assign it to the foldables_tutorial plugin then, click create class delete the created foldablelayoutinfo cpp file and only keep its header file in the header file called foldablelayoutinfo h, set up a struct to store all needed data from the windowmanager #pragma once #include "core h" enum efoldstate { undefined_state, flat, half_opened }; enum efoldorientation { undefined_orientation, horizontal, vertical }; enum efoldocclusiontype { undefined_occlusion, none, full }; struct ffoldablelayoutinfo { efoldstate state; efoldorientation orientation; efoldocclusiontype occlusiontype; fvector4 foldbounds; fvector4 currentmetrics; fvector4 maxmetrics; bool isseparating; ffoldablelayoutinfo state efoldstate undefined_state , orientation efoldorientation undefined_orientation , occlusiontype efoldocclusiontype undefined_occlusion , foldbounds -1, -1, -1, -1 , currentmetrics -1, -1, -1, -1 , maxmetrics -1, -1, -1, -1 , isseparating false { } }; implement jni code to implement jni, create a new c++ class with no parent and name it foldables_helper assign the class to the same plugin, then modify the c++ header and source files as follows in the created header file foldables_helper h , include foldablelayoutinfo h #include "foldablelayoutinfo h" then, declare a multicast_delegate to serve as a listener for passing the data from the java implementation to the rest of the engine declare_multicast_delegate_oneparam fonlayoutchangeddelegate, ffoldablelayoutinfo ; lastly, set up the methods and member variables class foldables_tutorial_api ffoldables_helper { public static void init ; static bool haslistener; static fonlayoutchangeddelegate onlayoutchanged; }; moving to the source file foldables_helper cpp , set up the definitions for the methods and member variables created in the header file bool ffoldables_helper haslistener = false; fonlayoutchangeddelegate ffoldables_helper onlayoutchanged; void ffoldables_helper init { haslistener = true; } now, in the same source file, create the native version of the onlayoutchanged function created in the foldablehelper java file since the java onlayoutchanged function only works on android, surround the function with an #if directive to ensure that it compiles only on android #if platform_android #endif within this directive, copy the code below to use the jni definition of the java onlayoutchanged function extern "c" jniexport void jnicall java_com_samsung_android_gamedev_foldable_foldablehelper_onlayoutchanged jnienv * env, jclass clazz, jobject jfoldablelayoutinfo { create the ffoldablelayoutinfo to store the data retrieved from java ffoldablelayoutinfo result;

broadcast the result via the onlayoutchanged delegate for use in the engine if ffoldables_helper haslistener { ue_log logtemp, warning, text "broadcast" ; ffoldables_helper onlayoutchanged broadcast result ; } } create a player controller and two ui states this section focuses on adding a player controller and creating two user interface ui states for flat and flex modes these objects are needed for the flex mode logic implementation following are the steps to add a player controller and create two ui states add a new player controller blueprint in content browser, go to content > thirdpersoncpp and right-click on blueprints > add/import content > blueprint class pick player controller as its parent class rename it as flexplayercontroller notethe flexplayercontroller added is generic and can be replaced by your custom player controller in an actual project add a new c++ class with actor component as its parent class name it as foldables_manager and assign it to the foldables_tutorial plugin click the create class button open the flexplayercontroller blueprint by double-clicking it click open full blueprint editor attach the actor component to the flexplayercontroller in the left pane, click add component, then find and select the foldables_manager next, create a pair of userwidget classes for the ui layouts needed flat mode ui for the full screen or normal mode; and flex mode ui for split-screen in add c++ class window, select the show all classes checkbox find and pick userwidget as the parent class then, click next name the new user widget as flatui and attach it to the plugin click next repeat the process but name the new user widget as flexui you might get an error when trying to compile stating that the userwidget is an undeclared symbol to fix this, open the foldables_tutorial build cs file, and in the publicdependencymodulenames addrange call, add "inputcore" and "umg" to the list create a pair of blueprints made from subclasses of these two user widgets right-click on content and create a new folder called foldui inside the newly created folder, right-click to add a new blueprint class in all classes, choose flatui and click the select button rename the blueprint as bp_flatui in the same folder, repeat the process but choose the flexui class and rename the blueprint as bp_flexui double-click on bp_flatui and bp_flexui, then design your two uis like below to visualize switching between flat and flex mode flat ui flex ui notethis code lab activity does not cover the steps on how to create or design ui if you want to learn about how to create your own game design in unreal engine 4, refer to unreal motion graphics ui designer guide implement the flex mode logic after creating the flexplayercontroller and the two ui states bp_flatui and bp_flexui , you can now implement flex mode logic in the foldables_manager open the foldables_manager h and include the necessary c++ header files #pragma once #include "coreminimal h" #include "components/actorcomponent h" #include "engine h" #include "flatui h" #include "flexui h" #include "foldables_helper h" #include "foldables_manager generated h" remove the line below to save a little bit of performance as this component doesn't need to tick public // called every frame virtual void tickcomponent float deltatime, eleveltick ticktype, factorcomponenttickfunction* thistickfunction override; set up the functions needed in foldables_manager the constructor, a function to create the ui widgets the implementation of onlayoutchanged delegate public // sets default values for this component's properties ufoldables_manager ; void createwidgets ; protected // called when the game starts virtual void beginplay override; protected void onlayoutchanged ffoldablelayoutinfo foldablelayoutinfo ; then, set up the variables needed references to the flat and flex ui classes references to the flat and flex ui objects mark the pointers as uproperty to ensure that garbage collection does not delete the objects they point to tsubclassof<uuserwidget> flatuiclass; tsubclassof<uuserwidget> flexuiclass; uproperty class uflatui* flatui; uproperty class uflexui* flexui; finally, define a new private function restoreflatmode , to disable flex mode and return to normal mode private void restoreflatmode ; moving over to foldables_manager cpp, implement the constructor using the constructorhelpers, find the ui classes and set the variables to store these classes also, set the bcanevertick to false to prevent the component from ticking and remove the code block of tickcomponent function // sets default values for this component's properties ufoldables_manager ufoldables_manager { primarycomponenttick bcanevertick = false; static constructorhelpers fclassfinder<uflatui> flatuibpclass text "/game/foldui/bp_flatui" ; static constructorhelpers fclassfinder<uflexui> flexuibpclass text "/game/foldui/bp_flexui" ; if flatuibpclass succeeded { flatuiclass = flatuibpclass class; } if flexuibpclass succeeded { flexuiclass = flexuibpclass class; } } next, set up the beginplay function to link the delegate to the onlayoutchanged function, to initialize the foldables_helper, and to create the widgets ready for use in the first frame // called when the game starts void ufoldables_manager beginplay { super beginplay ; ffoldables_helper onlayoutchanged adduobject this, &ufoldables_manager onlayoutchanged ; ffoldables_helper init ; createwidgets ; } set up the createwidgets function to create the widgets using the ui classes acquired in the constructor add the flatui widget to the viewport, assuming the app opens in normal mode until it receives the foldablelayoutinfo void ufoldables_manager createwidgets { flatui = createwidget<uflatui> aplayercontroller* getowner , flatuiclass, fname text "flatui" ; flexui = createwidget<uflexui> aplayercontroller* getowner , flexuiclass, fname text "flexui" ; flatui->addtoviewport ; } afterward, create the onlayoutchanged function, which will be called via a delegate inside this function, check whether the device’s folded state is half_opened if so, check whether the orientation of the fold is horizontal void ufoldables_manager onlayoutchanged ffoldablelayoutinfo foldablelayoutinfo { //if state is now flex if foldablelayoutinfo state == efoldstate half_opened { if foldablelayoutinfo orientation == efoldorientation horizontal { notefor this third person template, splitting the screen vertically isn’t ideal from a user experience ux point of view for this code lab activity, split the screen only on the horizontal fold top and bottom screen if you want it vertically, you need to use the same principle in the next step but for the x-axis instead of the y-axis you must also ensure that you have a flex ui object for the vertical layout if the device is both on flex mode and horizontal fold, change the viewport to only render on the top screen using the normalized position of the folding feature then in an asynctask on the game thread, disable the flatui and enable the flexui however, if the device is on normal mode, then return to flat ui using restoreflatmode function //horizontal split float foldratio = float foldablelayoutinfo foldbounds y / foldablelayoutinfo currentmetrics w - foldablelayoutinfo currentmetrics y ; gengine->gameviewport->splitscreeninfo[0] playerdata[0] sizex = 1 0f; gengine->gameviewport->splitscreeninfo[0] playerdata[0] sizey = foldratio; asynctask enamedthreads gamethread, [=] { if flatui->isinviewport { flatui->removefromparent ; } if !flexui->isinviewport { flexui->addtoviewport 0 ; } } ; } else { restoreflatmode ; } } else { restoreflatmode ; } } reverse the flex mode implementation logic to create the restoreflatmode function by setting the viewport to fill the screen, then disable the flexui and enable the flatui void ufoldables_manager restoreflatmode { gengine->gameviewport->splitscreeninfo[0] playerdata[0] sizex = 1 0f; gengine->gameviewport->splitscreeninfo[0] playerdata[0] sizey = 1 0f; asynctask enamedthreads gamethread, [=] { if !flatui->isinviewport { flatui->addtoviewport 0 ; } if flexui->isinviewport { flexui->removefromparent ; } } ; } set up a game mode and attach the flexplayercontroller the game mode defines the game rules, scoring, and any game-specific behavior set up the game mode in unreal editor by creating a blueprint class in the content > thirdpersoncpp > blueprints folder pick game mode base as the parent class and rename it as flexgamemode double-click on flexgamemode in the drop-down menu next to player controller class, choose the flexplayercontroller lastly, go to edit > project settings > project > maps & modes and select flexgamemode as the default gamemode build and run the app go to edit > package project > android to build the apk ensure that the android development environment for unreal is already set up to your computer noteif the build failed due to corrupted build tools, consider downgrading the version to 30 or lower using the sdk manager or, simply rename d8 bat to the name of the missing file dx bat in sdk path > build-tools > version number directory and, in lib folder of the same directory, rename d8 jar to dx jar after packaging your android project, run the game app on a foldable galaxy device and see how the ui switches from normal to flex mode if you don’t have any physical device, you can also test it on a remote test lab device tipwatch this tutorial video and know how to easily test your app via remote test lab you're done! congratulations! you have successfully achieved the goal of this code lab now, you can implement flex mode in your unreal engine game app by yourself! if you're having trouble, you may download this file flex mode on unreal complete code 20 16 mb to learn more, visit www developer samsung com/galaxy-z www developer samsung com/galaxy-gamedev
