introduction in 2019, samsung released the galaxy fold, our first foldable device with one ui. since then, we've partnered with companies around the world to optimize user experiences for the galaxy z series' flip and fold form factors. we've also worked to meet users' growing needs for tablets and other devices with large screens. these interface and interaction guidelines are provided with examples to help you deliver enjoyable and productive experiences on foldable and large-screen devices. large screen ui responsive layout is essential the galaxy z fold series has two screens on one device – the cover screen is visible when the device is folded, and the main screen is visible when the device is unfolded. since users fold and unfold their devices frequently, it’s important to provide an optimized layout for each screen. by dynamically changing the ui to match the screen size, optimized layouts can also be applied to devices with larger screens such as tablets. responsive layout is also essential for app continuity between screens. go to app continuity check points ! 1. does your app display correctly on screens with various sizes, widths, and aspect ratios? 2. does your app support landscape orientation? 3. does your app display correctly on both the cover screen and main screen? 4. does your app fill the entire screen? * dpi can be changeable in settings for the main screen (screen layout and zoom) between phone ui (less than sw 600) and tablet ui (sw 600 or more). find out more on responsive layouts android developers responsive ui material design don’t waste the extra space our research shows that foldable device users use apps on both the main screen and cover screen, depending on which one is more convenient at the time. however, users are unhappy when an app is simply stretched out to fit the large main screen when the device is unfolded. don't stretched phone layout do large screen optimized layout ideal layouts for large screen users feel that stretched-out apps are just wasting the extra space of the large screen, which is supposed to be one of the primary benefits of the device. here are useful tips for designing an ideal layout for large screen. show more information at once on larger screens, a dual-pane layout lets you show the app hierarchy. by flattening navigation, users can access content quickly without a full-screen transition. multi-pane ui: dual-pane check points ! 1. make navigation faster by showing a list of items along with the item details at the same time. find out more on sliding pane layout android developers activity embedding android developers navigation rails and 3-pane layouts may be a better fit for some apps. if possible, make your app support navigation rail, dual-pane, and triple-pane layouts depending on the screen size and orientation. multi-pane ui: navigation rail, triple-pane check points ! 1. use a simplified list for the fold screen in portrait. 2. use a triple-pane layout for tablets in landscape get the most out of the available screen space. 3. use the standard navigation drawer on large screen layout. find out more on navigation rail material design get things done without leaving the screen for an input field that requires a small amount of information, use a small pop- over instead of filling the entire screen. showing on top of the previous screen helps users accomplish their task without forgetting what they were working on. pop-over check points ! 1. use a pop-over for simple actions such as creating and editing. do more at the same time your app may have a feature that is useful to remain visible, but doesn’t require frequent interaction. in these cases, use a small floating widget that can appear on top of other apps. mini ui check points ! 1. use floating widgets to let users use multiple features at the same time. reduce finger travel distance on large screens, pop-ups should appear near the button or other ui element that the user interacted with to cause the pop-up to appear. keeping the pop-up near the button reduces finger travel distance and saves time. proximity pop-ups check points ! 1. show pop-ups near the last place that the user touched on the screen. more app examples communication apps these apps take advantage of dual pane, adjustable split bar and pop over. camera & photo-taking apps these apps take full advantage of large screens when taking photos and capturing images. emoji editing responsive layout designed for phones, foldables, and tabletshow to use extra space in landscape view content browsing & viewing apps responsive layout designed for phones, foldables, and tablets list and grid change according to screen size adjustable split bar in dual-pane view uses pop-overs supports flex mode for video viewing app continuity and multi-tasking

ux and ui considerations foldable devices bring different screen size and shape to the market. hence, the way people use your app may vary from past years. by considering new layouts and navigation patterns, app developers can explore opportunities to build greater experience in larger screen devices. handle diverse aspect ratios on devices where your application takes up the entire screen, large-screen form factors mean you need to allow for various aspect ratios. for example, in the samsung z fold series, the aspect ratio of the cover screen is similar to a bar-type device, whereas the ratio of the main screen is close to square. take a communication app, users may place it in a tall, narrow window at the edge of the screen so they can view and respond to messages while working with another app that occupies the rest of the screen. there is no magic bullet to addressing this diversity of aspect ratios, you will need to test and support these as best as possible. however, if your app’s content is unsuitable for certain aspect ratios, use the minaspectratio flag, introduced in android 10, or the maxaspectratio flag to constrain your app within workable aspect ratios. to be compatible with samsung foldable devices, you should test your apps for these ratios. responsive layout you can make better use of larger screens by considering ways to surface more information or to show content more efficiently. spotify is one good example, which is designed to deliver more content and to provide more optimized and convenient navigation according to various screen sizes. find out more on: android at large: how to bring optimized experiences to the big screen

implement app continuity and optimize large screen ui of a gallery app objective learn how to apply app continuity and large screen optimization on a gallery app for seamless experience on foldable devices. overview samsung foldable devices have two different physical screens: the cover display and the larger main display. app continuity lets you experience a seamless transition between these displays. when using an app that supports app continuity, you can unfold the device and continue where you left off. with this feature, apps can run without interruption when it receives a configuration change event, such as when a device is folded or unfolded. it is essential to continue the operation by keeping the same state and location of the app after the transition. large screen optimization plays another significant role in terms of ux designing for foldable devices. the screens of foldable devices have a wide range of aspect ratios, careful ux design is needed to suit two different size displays. set up your environment you will need the following: java se development kit (jdk) 8 or later android studio (latest version recommended) samsung galaxy fold, z fold2, z fold3, or newer remote test lab (if physical device is not available) requirements: samsung account java runtime environment (jre) 7 or later with java web start internet environment where port 2600 is available sample code here is a sample code for you to start coding in this code lab. download it and start your learning experience! app continuity sample code (2.80 mb) start your project after downloading the sample code containing the project file for this code lab, open your android studio and click open an existing project. locate the downloaded android project from the directory and click ok. handle the configuration change to have a seamless experience when using a gallery app, the photo that is displayed after folding or unfolding the device should be the same as the previous. you need to store the position or id of the photo, as android destroys and recreate the activity when folding and unfolding the phone. use bundle with its key/value pair to store and restore the values. in addition, you need to consider the screen rotation in order to keep the app running, as android restarts the activity of the app after the configuration changes. let's first start to prevent the activity from restarting, by handling the configuration change for mainactivity in androidmanifest.xml file. android:configchanges="keyboardhidden|orientation|screensize" save the instance state by storing the data before the activity is destroyed when the screen changes from main to cover display or vice versa, android provides us an override method called onsaveinstancestate. it accepts a bundle as a parameter. use putint method to store data into key/value pair. override fun onsaveinstancestate(outstate: bundle) { outstate.putint("currentposition", currentimageposition) log.i("tag", "onsave "+currentimageposition) super.onsaveinstancestate(outstate) } retrieve the stored values when the app is first developed, the savedinstancestate will be null inside the oncreate method. if it is not null, you can retrieve the stored values from the bundle using getint and the key name you set up in the previous step while storing. if(savedinstancestate != null) { selectedimageview!!.setimageresource(images[savedinstancestate.getint("currentposition")]) customgalleryadapter!!.updateposition(images[savedinstancestate.getint("currentposition")]) currentimageposition = savedinstancestate.getint("currentposition") log.i("tag", "onsaved " + savedinstancestate.getint("currentposition")) } create a layout file for the main display the next thing to do, is to optimize the app's large screen ui. here, you will add a navigator for the photos when using the app in the main display, since it has more space. android offers an alternate resources option based on various criteria like display size, density, and other more. you can use two different layout files for each display using alternate resources of android. create a new directory in res in the form of [resource]-[qualifier] for cover display and main display. the appropriate version of the resource is shown automatically by the system based on the smallest width qualifier of sw. the cover display will be between sw240 and sw480, while the main display will be sw600. create a new directory named layout-sw600dp under the res directory and then create an xml file named activity_main. res/ layout/ activity_main.xml layout-sw600dp/ activity_main.xml add the layout code add the gallery layout code shown below, in layout-sw600dp/activity_main.xml file. <?xml version="1.0" encoding="utf-8"?> <androidx.constraintlayout.widget.constraintlayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/linearlayout" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.xyz.gallery.mainactivity"> <imageview android:id="@+id/imageview" android:layout_width="wrap_content" android:layout_height="match_parent" android:gravity="center_vertical" app:layout_constraintend_toendof="parent"

android:layout_marginbottom="4dp" android:gravity="fill" android:orientation="horizontal" android:padding="10dp" android:spacing="5dp" app:layout_constraintbottom_tobottomof="parent" app:layout_constraintend_toendof="parent" app:layout_constrainthorizontal_bias="0.0" app:layout_constraintstart_tostartof="parent" /> </androidx.constraintlayout.widget.constraintlayout> run the app after building the apk, you can run the gallery app and see how it change when you fold and unfold the device. 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. noteapp continuity when folding the device, can be turned on for selected apps in settings (if the app supports app continuity). to continue using the gallery app on the cover display when you close your phone, go to settings> display > continue apps on cover screen > toggle on gallery app. foldable devices let you decide whether you want to see less or more content at the same time in the main display. to see the photo navigator added in the app, go to settings> display > screen layout and zoom > see more content at the same time. you're done! congratulations! you have successfully achieved the goal of this code lab. now, you can optimize your app to support continuity and large screen layout by yourself! if you're having trouble, you may download this file: app continuity complete code (24.44 mb) to learn more about developing apps for galaxy foldable devices, visit:

foldable 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.
