apache cordova is an excellent option for developers who already have a web application and want to port it to the different mobile platforms, or just want to have a consistent way to create cross-platform mobile web apps. this blog is the first in a series to introduce you to cordova, and how to create different types of mobile applications using standard web technologies. in this post, we will cover cordova basics and the prerequisites for your development environment. the following post will get into details on how to create your first app, and then to publish the resulting apk in samsung’s galaxy store. in an upcoming blog i’ll talk about photon storm’s phaser, that is one of the most trusted frameworks for developing professional-quality 2d games in javascript. with phaser, it’s feasible to make performant games that run smoothly in all major mobile operating systems, while only having to maintain one codebase. additionally, you can rely on the huge javascript community to keep creating libraries that you can easily integrate in your games. what is a mobile web app let’s start checking what is a mobile web application: in the context of this post, we will refer to applications for mobile devices that require only a web browser to be installed on mobile device. they commonly use html and ajax, but are not written specifically for one mobile operating system. mobile web applications differ from mobile native applications, in that they use web technologies and are not limited to the underlying platform for deployment. this will give you the advantage of creating cross-platform applications using technologies that you may be familiar with in your front-end projects, and the ability to access a wide array of libraries and popular frameworks. what is cordova a typical challenge faced by mobile app developers is to achieve solid support of as many mobile clients as possible, and each one can have its own set of quirks and drawbacks. this, clearly, increases costs and development time. that is why cross-platform development tools like cordova are so widely used and supported. cordova is a platform used for building mobile apps with standard web technologies, namely html, css and javascript. think of cordova as a container that connects your web apps with native mobile functionalities through a unified javascript api. web applications don’t have access to native mobile functionalities by default, and that is the problem that cordova was created to solve. cordova connects the world of web app development and mobile devices, creating hybrid mobile apps that can use camera, geolocation, file system and other native mobile capabilities. in this post we will focus on the use of the cordova cli (command line interface), mainly because you will be able to use it for multiple platforms, and that fits perfectly with the needs of most developers interested in using cordova, to start with. pros of cordova easy to learn: if you are a front end developer, cordova has an easy learning curve. you can easily apply your skills as a web developer, and knowledge of standard web technologies, to build an app with cordova. all you really need is to learn a little bit about the command line tools and you will be running with cordova in no time. access to native functionalities: with cordova, you will have access to native device capabilities, such as the camera, push notifications, contacts, geolocation, accelerometer, sms, and others. open source: anyone can contribute to cordova’s source code to make it better. this also gives it a solid contributor base that is creating custom plugins and fixing bugs. cross-platform development: cordova compiles your app into a package file, which is required by most app stores. this means that apps created with cordova can easily be deployed to the mobile operating system your choosing. if you’re deploying to android, cordova creates an apk (android application package) file. this is the file that we will create in this blog post. prerequisites: node.js we’ll be dealing with purely javascript (and perhaps a little bit of html) through this post, so all you need to install manually is node.js. this will give you the node and npm executables on your system. to install node.js you can go to their official site and download the latest version available for your operating system. on mac you can download the installer from the official page: or you can download the package with bash: curl "https://nodejs.org/dist/latest/node-${version:-$(wget -qo- https://nodejs.org/dist/latest/ \ | sed -ne 's|.*>node-(.*)\.pkg</a>.*|\1|p')}.pkg" > "$home/downloads/node-latest.pkg"\ && sudo installer -store -pkg "$home/downloads/node-latest.pkg" -target "/" on windows is just easier to download the correct installer: and then follow the instructions: it may prompt you to install more necessary tools. installing cordova once node.js is installed, download the apache cordova command line by running this command in your terminal/command prompt. the cordova module will automatically be downloaded by the npm utility. on windows you should open your command shell and type: npm install -g cordova on mac and linux open your terminal and type: sudo npm install -g cordova you may be prompted to type your operating system password, and after that you should see the installation progress in your command or terminal window. the -g flag in the command above is needed so npm installs cordova globally. if you don’t use this option, cordova will be installed only for your the current working directory. after the installation is completed, you can type cordova on the command line and it should display the main help for the cordova cli. that's it for today. in the next post, we'll talk more about using this tool. talk with us we love to chat with mobile game developers and help you as you develop, publish, and market your own games. galaxy store is a great place to publish your game and get discovered. if you are a mobile app developer and want to request a quick chat with us, just fill out this form.

the galaxy watch running wear os powered by samsung can detect events like hard falls. to detect the hard falls, the watch uses a built-in accelerometer. using the health services api, you can receive a fall detection event in your watch application. in this blog, we create a wear os application to identify a fall detection event and demonstrate how to use the health services api to achieve this on the galaxy watch. the galaxy watch uses the fall detection event in its sos feature. for more information, see use your samsung smart watch in an emergency situation. it can be used to take care of elderly people or patients. how to trigger a fall detection event in your application on the galaxy watch if the functionality provided with the watch is not sufficient for your solution, you can use the health services api to detect this event in your own application. in this section, we describe all the important steps that you must follow when building an events tracking app. as an example, we use the eventsmonitor sample project. project settings before you start writing your code, you need to import the health services api library in the dependencies section of the app/build.gradle file. implementation androidx.health:health-services-client:1.0.0-beta01 now you are ready to use the health services api. get passivemonitoringclient passivemonitoringclient enables tracking of the data in the background (without requiring an ongoing workout) and the events that can occur. you need to get this client to make your application suscribe to the events. private var healthservicesclient: healthservicesclient private var passivemonitoringclient: passivemonitoringclient init { healthservicesclient = healthservices.getclient(context) passivemonitoringclient = healthservicesclient.passivemonitoringclient } ask for permissions in the first step, you need to modify the androidmanifest.xml file. add the <uses-permission> element in the global section: <uses-permission android:name="android.permission.activity_recognition" /> <uses-permission android:name="android.permission.receive_boot_completed" /> <uses-permission android:name="android.permission.foreground_service" /> add the <queries> element: <queries> <package android:name="com.google.android.wearable.healthservices" /> </queries> it is a good practice to ask for the required permissions whenever the application tries to use this data type. first, you should check whether the user has consented to use the particular functionality. permissiongranted = applicationcontext.checkselfpermission( manifest.permission.activity_recognition) == packagemanager.permission_granted if not, you must ask for it before using the api. private fun requestpermissions() { permissionlauncher.launch(android.manifest.permission.activity_recognition) } to ask about permissions, you need to create a request permissions object. permissionlauncher = registerforactivityresult(activityresultcontracts.requestpermission()) { result -> permissiongranted = result } this is an example of a permission request window: using health services api to get events to asynchronously receive information about a fall detection event, provide the class which inherits from the passivelistenerservice class and override the onhealtheventreceived method. class passivehealtheventservice : passivelistenerservice() { override fun onhealtheventreceived(event: healthevent) { runblocking { log.i(tag, "onhealtheventreceived received with type: ${event.type}") healthservicesmanager.getinstance(applicationcontext).recordhealthevent(event) super.onhealtheventreceived(event) } } } add information about this class with the permissions to the androidmanifest.xml file. <service android:name=".passivehealtheventservice" android:exported="true" android:permission="com.google.android.wearable.healthservices.permission.passive_data_binding" /> when you have the passivemonitoringclient and passivehealtheventservice classes, you can then subscribe to the events. private val healtheventtypes = setof(healthevent.type.fall_detected) suspend fun registerforhealtheventsdata() { log.i(tag, "registering listener") val passivelistenerconfig = passivelistenerconfig.builder() .sethealtheventtypes(healtheventtypes) .build() passivemonitoringclient.setpassivelistenerserviceasync( passivehealtheventservice::class.java, passivelistenerconfig ).await() registered = true } if you no longer want to receive information about the fall detection event, please unregister your application from the service. this can be done using the passivemonitoringclient api. suspend fun unregisterhealtheventsdata() { log.i(tag, "unregistering listeners") passivemonitoringclient.clearpassivelistenerserviceasync().await() registered = false } the healthevent class contains information about the event, such as: type - returns the type of the event (fall_detected, unknown). instant - returns the time of the health event. datapointcontainer - returns the metrics associated with the event. test application on the galaxy watch you can test this functionality in the following two ways: manual test you can simulate a fall by trying to fall on a mat. note : before performing the manual test, ensure that you have taken all safety precautions for yourself. for example, use cushions to soften the fall impact, etc. synthetic data provider use the command line to run and execute commands with the synthetic data provider. for more details about this feature, see synthetic data provider. with adb, you can send subsequent commands to the device. to start the synthetic data provider, run the following command: $ adb shell am broadcast \ -a "whs.use_synthetic_providers" \ com.google.android.wearable.healthservices to simulate a fall, run the following command: $ adb shell am broadcast \ -a "whs.synthetic.user.fall_over" \ com.google.android.wearable.healthservices when the tests are finished, to switch back to using real sensors, run the following command: $ adb shell am broadcast \ -a "whs.use_sensor_providers" \ com.google.android.wearable.healthservices resources this blog is based on the eventsmonitor application. the whole presented code comes from this application. the entire application can be downloaded from: eventsmonitor version 1.0 (86,0kb) dec 12, 2022 enjoy your adventure creating the ultimate health application now you are ready to start the fall detection event in your application. we encourage you to try doing it by yourself and explore other features provided by the health services sdk.

galaxy watch offers a convenient way of measuring exercise progress. modern sensors designed specifically for health services provide the most precise readings. after connecting to health services, you can measure certain exercises and track their values. this blog describes all the important steps to build an exercise tracking app using the health services api. we use example code introduced in health code lab for tracking exercise. you can download the source code from this code lab. health services defines a variety of exercise types. for a full exercise type list, take a look at exercisetype. on galaxy watch4 and galaxy watch4 classic, a repetition counter is available for the following exercises: back_extension barbell_shoulder_press bench_press bench_sit_up burpee crunch deadlift forward_twist dumbbell_curl_right_arm dumbbell_front_raise dumbbell_lateral_raise dumbbell_triceps_extension_left_arm dumbbell_triceps_extension_right_arm dumbbell_triceps_extension_two_arm dumbbell_curl_left_arm jump_rope jumping_jack lat_pull_down lunge squat upper_twist in this application, we are going to use deadlift. the example code used for deadlift can be easily adapted to track all repetition-based exercises. the basics of connecting to health services are covered in the blog using health services on galaxy watch. setting up an exercise once connected to the health services api, we are ready to set up the exercise. in this case we use deadlift as a sample exercise. first, we need to get the exercise client: exerciseclient exerciseclient = client.getexerciseclient(); after that, we need to set the exercise type in the configuration builder: exercisetype exercisetype = exercisetype.deadlift exerciseconfigbuilder exerciseconfigbuilder = exerciseconfig.builder() .setexercisetype(exercisetype); to see what can be tracked for our exercise, we need to check its capabilities. we do this by using a listenablefuture object and listening for a callback from health services. listenablefuture<exercisecapabilities> capabilitieslistenablefuture = exerciseclient.getcapabilities(); when we receive a callback, we can receive a set with capabilities: futurecallback<exercisecapabilities>() { @override public void onsuccess(@nullable exercisecapabilities result) { try { exercisetypecapabilities exercisetypecapabilities = result.getexercisetypecapabilities(exercisetype); set<datatype> exercisecapabilitiesset = exercisetypecapabilities.getexercisecapabilities(result); } if you do not want to track some of these values, at this point, you can remove them from a set. by default, all datatypes that a certain exercise can measure are being stored as a set. by removing them before setting up a configuration builder, you can exclude tracking unnecessary values. once we are ready, we can finish configuring an exercise: exerciseconfigbuilder = exerciseconfig.builder() .setexercisetype(exercisetype) .setdatatypes(exercisecapabilitiesset); setting up exercise listener an exercise listener is an object that allows us to get exercise updates from health services, whenever they are available. to set up the listener, we need to override three methods: exerciseupdatelistener exerciseupdatelistener = new exerciseupdatelistener() { @override public void onexerciseupdate(exerciseupdate update) { //processing your update } @override public void onavailabilitychanged(datatype datatype, availability availability) { //processing availability } @override public void onlapsummary(exerciselapsummary summary) { //processing lap summary } }; starting and stopping the exercise we are ready to start tracking our exercise. to do that, we use the listenablefuture object that gets callbacks from the healthservices api whenever an update is available. to build this object, we send our configuration to the exercise client while starting measurement: listenablefuture<void> startexerciselistenablefuture = exerciseclient.startexercise(exerciseconfigbuilder.build()); when we get a callback from the healthservices api, we start our listener: listenablefuture<void> updatelistenablefuture = exerciseclient.setupdatelistener(exerciseupdatelistener); we finish exercise in a similar way, by creating a listenablefuture object that asks the health services api to stop tracking exercise: listenablefuture<void> endexerciselistenablefuture = exerciseclient.endexercise() processing exercise update data exercise update data contains various information about the performed exercise. after setting up a listener, we retrieve it in a callback: public void onexerciseupdate(@nonnull exerciseupdate update) { try { updaterepcount(update); } catch (deadliftexception exception) { log.e(tag, "error getting exercise update: ", exception); } } in this example, we focus on one of most important readings—latest metrics. we store them in a map: map<datatype, list<datapoint>> map = update.getlatestmetrics(); now we can read particular values by looking for their key: list<datapoint> reppoints = map.get(datatype.rep_count); list<datapoint> caloriespoints = map.get(datatype.total_calories); the last value on the list is the latest reading in the current update. we can use it in our application, for example, when updating a label: string repvalue = string.format("%d", iterables.getlast(reppoints).getvalue().aslong()); txtreps.settext(string.format("reps count: %s", repvalue)); this is how exercise data can be accessed and processed using health services on galaxy watch. it’s a quick and convenient way to track its progress that everybody can implement into a watch application.

maintaining the legacy of foldable technology, samsung recently released the new galaxy z fold2. this device is designed to provide a new and seamless experience to users with its infinity flex display. as a developer, you can adjust your app to provide the best ui experience to your users. in this blog, we will demonstrate how a stopwatch app can be modified to adjust with galaxy z fold2 devices. the stopwatch app is pretty simple, having three functionalities—start, pause and reset the time. figure 1: stopwatch app example in order to provide a seamless experience to the user, we have to ensure app continuity, adjust the activity according to the ui, support multi-resume in multi-window, and check the display cutout. so let’s get started. app continuity like the previous galaxy z fold, the new galaxy z fold2 has two separate physical screens. the cover display is 2260 x 816 pixels and the main display is 2208 x 1768 pixels. to provide a seamless experience to the user while folding and unfolding the device, the app must maintain its continuity by preventing data loss. you can ensure continuity by using the onsaveinstancestate() method. first, save the data of the current state with onsaveinstancestate(). for the stopwatch app, the time that has passed is saved in seconds before the activity is paused. @override public void onsaveinstancestate(bundle savedinstancestate) { savedinstancestate.putint("seconds", seconds); savedinstancestate.putboolean("running", running); savedinstancestate.putboolean("wasrunning", wasrunning); } then restore the data of the activity using the oncreate() function. @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_main); if (savedinstancestate != null) { seconds = savedinstancestate.getint("seconds"); running = savedinstancestate.getboolean("running"); wasrunning = savedinstancestate.getboolean("wasrunning"); } } figure 2: continuity of the stopwatch while folding and unfolding the device ensure dynamic resizing of your app if you want your app to support multi-window mode, define the activity as resizable. this can be done by setting the resizableactivity attribute to true in manifest.xml. this ensures the maximum compatibility with both the cover screen and the main screen of the device. <activity android:name=".mainactivity" android:resizeableactivity="true"> … </activity> another approach is to define an aspect ratio for your app. galaxy z fold2’s cover screen has a ratio of 25 : 9 whereas the main screen has a ratio of 22.5 : 18. to be compatible with the device, you should test your apps for these ratios and that they fill up the entire display. you can use the minaspectratio or the maxaspectratio flag to constrain your app within the feasible aspect ratios. please note that, if the resizableactivity attribute is set to true, the minaspectratio and the maxaspectratio flag are ignored. figure 3: dynamically resizable app in pop-up view and split-window view multi-resume for multi-window up to android 9, only one of the activities visible in the multi-window operation is allowed to stay in the resumed state. all other activities are put into the paused state. therefore, you have to force your app to be in the resumed state by adding the following in the manifest.xml file. <meta-data android:name="android.allow_multiple_resumed_activities" android:value="true" /> however, starting from android 10, all activities visible in multi-window are allowed to stay in the resumed state. you no longer need to force your app to have multi-resume behavior. however, there are some cases where an app can be in the paused state in android 10, in which case you need to enforce the multi-resume behavior: • in a minimized split-screen (with launcher on the side), the top activity isn't resumed because it's not focusable • in picture-in-picture mode, the activity isn't resumed because it's not focusable • when activities are covered by other transparent activities in the same stack figure 4: multi-resume in multi-window display cutout the main display of the galaxy z fold2 has a punch hole in the upper right side. you can set a display cutout mode according to your content style. by default, the content is rendered into the cutout area while in portrait mode and letterboxed while in landscape mode. if you want your content to be rendered into the cutout area in both portrait and landscape modes, you can define the mode as shortedges. in the sample app, the cutout mode is set to shortedges in the style.xml file. the sample app is set to full screen and display cutout mode is set to shortedges. <item name="android:windowlayoutindisplaycutoutmode">shortedges</item> <item name="android:windowtranslucentnavigation">true</item> figure 5: display cutout default mode figure 6: display cutout in shortedges mode hopefully this blog helps you to update your app for the galaxy z fold2 and give the user a better ui experience. to check out the sample app, click here. you can also view samsung’s official documentation for galaxy z devices. if you have any questions regarding foldable ui, feel free to post it in the samsung developers forums.
