Connecting Galaxy Watch to Watch Face Studio over Wi-Fi

watch face studio (wfs) is a powerful watch face design tool for wear os-based smartwatches that allows you to test watch faces within the tool. however, since most designers prefer testing their watch faces on real devices, wfs also provides the "run on device" feature that deploys watch face projects directly to real devices. the connectivity policies have changed in wear os 4. this article describes how to connect a galaxy watch running wear os powered by samsung (running wear os 4 or later) to wfs over wi-fi both through the wfs interface and through the command line interface. prerequisites prepare the galaxy watch for connecting to wfs over wi-fi: disable bluetooth on the watch. enable wi-fi on the watch and connect it to the same network as your computer. the wireless network can be through a router or a mobile hotspot.to connect to a wi-fi network, go to settings > connections > wi-fi, check that wi-fi is enabled, and select the network to join. figure 1: wi-fi enabled on watch if you have not already enabled developer mode on the watch, enable it.go to settings > about watch > software information and tap the software version item 5 times. figure 2: software version item you receive a toast notification when developer mode is enabled. the “developer options” menu item now can be found below “about watch” on the “settings” menu. figure 3: “developer options” item in “settings” menu enable adb debugging.in the “developer options” menu, toggle the adb debugging switch on. figure 4: adb debugging enabled enable wireless debugging.in the “developer options” menu, toggle the wireless debugging switch on. figure 5: wireless debugging enabled retrieve the connection ip address and port.when wireless debugging is enabled, a menu item appears with the watch’s ip address and port. make a note of this information, as it is needed to connect the watch to wfs. figure 6: connection ip address and port retrieve the pairing code, ip address, and port.in the “wireless debugging” menu, select pair new device and note the pairing code and port number. you need this information to pair the watch with your computer. figure 7: pairing information you are now ready to connect the watch to the computer over wi-fi. notes although the connection and pairing ip addresses are the same, the port numbers are different. the pairing code and port number can change each time you connect the watch to your computer. use the watch face studio ui to connect your watch to wfs for deploying and testing your watch face: in the top right corner of your project in watch face studio, click run on device figure 8: “run on device” in wfs in the “connected devices” dialog, to add a new device, click the + button. figure 9: adding a device enter the connection and pairing information that you retrieved from the galaxy watch into the appropriate fields. figure 10: connecting galaxy watch using wfs click ok.the watch is added to the list of connected devices and your project can be launched on the watch. figure 11: watch connected to wfs use the command line you can also connect the watch to your watch face studio on your computer through the android debug bridge (adb) command line tool. adb is integrated into wfs, so a separate installation is not needed. to pair and connect the watch and computer over wi-fi using adb shell commands: open the command prompt or terminal on your computer. noteif you are using a windows computer and have not set the adb path environment variable, you must open the command prompt from within the following folder: “<your wfs installation folder>\tools\window.” navigate to the folder in windows explorer, right-click the window, and select open powershell window here. to pair the watch and computer, run the following command with the pairing ip address and port that you retrieved from the watch: adb pair <ip address:port> when prompted, enter the wi-fi pairing code. to connect the watch, run the following command in the terminal with the connection ip address and port that you retrieved from the watch: adb connect <ip address:port> figure 12: pairing and connection through command line in your wfs project, click run on device.the watch is in the list of connected devices and your project can be launched on the watch. summary this article has described how you can pair and connect galaxy watch running wear os 4 or later to watch face studio on your computer wirelessly through wi-fi. after connecting your watch, you can deploy and test your wfs project on the watch. if you have questions about or need help with the information in this article, you can share your queries on the samsung developers forum. for more specialized support, you can contact us through developer support.

From Wrist to Hand: Develop a Companion App for Your Wearable Application

galaxy watch applications can support many features and services on the watch hardware, but the watch's smaller size compared to a mobile device carries limitations, such as fewer hardware resources and smaller screen size. to take advantage of mobile hardware, you can develop a companion mobile application for the wearable application. the companion application handles complex and resource-intensive tasks while the wearable application provides a seamless experience. this tutorial uses android studio and kotlin to demonstrate how to create a multi-module project and communicate between a companion mobile application and a wearable application using the wearable data layer api. to test the application, you need a galaxy watch running wear os powered by samsung and a connected galaxy mobile device. prerequisites to develop a wearable application and its companion mobile application, create a multi-module project in android studio: create a new mobile application project. select file > new > new project > phone & tablet > empty activity and define an appropriate name and application id (package name) for the project. in the android studio environment, switch to project view. to create the wearable module, right-click the project name and select new > module > wear os > blank activity. make sure the application id for this module is identical to the mobile application. switch the android studio environment back to android view. to use the wearable data layer api to create a communication channel between the wearable and mobile applications, add the following dependency to the build.gradle file for both modules: dependencies { ... implementation 'com.google.android.gms:play-services-wearable:xx.x.x' } launching the companion application launching the companion mobile application from the wearable application includes the following steps, which can be implemented using the messageclient api: send a message from the wearable application to the mobile application. receive the message in the mobile application and launch an intent. send a message to the companion application a coroutine is needed to send messages from the wearable application to the mobile application, because this task cannot be carried out on the main thread. the coroutine creates a separate background thread on which to complete the work. to implement coroutines in the wearable application: add the following dependencies to its build.gradle file:implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core:x.x.x" implementation "org.jetbrains.kotlinx:kotlinx-coroutines-android:x.x.x" implementation "androidx.lifecycle:lifecycle-extensions:x.x.x" implementation "androidx.lifecycle:lifecycle-runtime-ktx:x.x.x" implementation "androidx.appcompat:appcompat:x.x.x" in the application code, modify the mainactivity class to inherit appcompatactivity() instead of activity(). in the androidmanifest.xml file, in the <application> element, change the android:theme attribute value to "@style/theme.appcompat.noactionbar" or another custom theme. now that you've implemented coroutines, let's develop a way to send a message to the companion application. in the xml file for the wearable module, define a ui with a button. while a mobile device can be connected to multiple wearables, a watch is typically connected to only a single device. therefore, send the message to the first node (connected device) on the watch using the messageclient api. to retrieve a list of the connected nodes, implement the following function: private fun getnodes(): collection<string> { return tasks.await(wearable.getnodeclient(context).connectednodes).map { it.id } } in the mainactivity class of the wearable module, add a listener to the ui button that uses the sendmessage() function of the messageclient api to send a message to the first node retrieved from the getnodes() function. the sendmessage() function requires three parameters: id of the receiving node. message path (specific address) of the receiving node. byte array of the information to be sent to the node. the size must be less than 100 kb. the message path is initialized in the companion object and is needed to receive the message on the mobile application. class mainactivity : appcompatactivity() { private lateinit var binding: activitymainbinding private var transcriptionnodeid: string? = null override fun oncreate(savedinstancestate: bundle?) { super.oncreate(savedinstancestate) binding = activitymainbinding.inflate(layoutinflater) setcontentview(binding.root) binding.deploybutton.setonclicklistener { lifecyclescope.launch(dispatchers.io){ transcriptionnodeid = getnodes().first()?.also { nodeid-> val sendtask: task<*> = wearable.getmessageclient(applicationcontext).sendmessage( nodeid, message_path, "deploy".tobytearray() //send your desired information here ).apply { addonsuccesslistener { log.d(tag, "onsuccess") } addonfailurelistener { log.d(tag, "onfailure") } } } } } } } companion object{ private const val tag = "mainwearactivity" private const val message_path = "/deploy" } listen for messages in the companion application a companion mobile application can be notified of incoming messages from the wearable application in two ways: extending the wearablelistenerservice class to create a service that listens for incoming messages even when the application is in the background implementing the messageclient.onmessagereceivedlistener interface in the mainactivity class of the mobile application since we want to react to the message by launching the companion application even when it is not running in the foreground, create a separate class that extends the wearablelistenerservice class. to receive messages from the wearable application, implement the following onmessagereceived() function: class phonelistenerservice: wearablelistenerservice() { override fun onmessagereceived(messageevent: messageevent) { log.d(tag, "onmessagereceived(): $messageevent") log.d(tag, string(messageevent.data)) if (messageevent.path == message_path) { val startintent = intent(this, mainactivity::class.java).apply { addflags(intent.flag_activity_new_task) putextra("messagedata", messageevent.data) } startactivity(startintent) } } companion object{ private const val tag = "phonelistenerservice" private const val message_path = "/deploy" } } in the androidmanifest.xml file of the mobile application, add the service and an intent filter for the listener service: <service android:name=".phonelistenerservice" android:enabled="true" android:exported="true"> <intent-filter> <action android:name="com.google.android.gms.wearable.message_received" /> <data android:host="*" android:pathprefix="/" android:scheme="wear" /> </intent-filter> </service> to test the project, build both applications and run them on your galaxy watch and mobile device. when you tap the ui button on the watch, the companion application launches on the mobile device. conclusion this tutorial has demonstrated how the wearable data layer api enables you to implement seamless communication between a galaxy watch running wear os powered by samsung and its connected mobile device. in addition to launching a companion application, the functions of the messageclient api can also be used to delegate complex tasks to the mobile device, creating more seamless user experiences for wearable applications. for more information about implementing communication between watch and mobile devices, see send and receive messages on wear. if you have questions about or need help with the information in this tutorial, you can share your queries on the samsung developers forum. for more specialized support, you can contact us through samsung developer support. stay tuned for the next blog on wearable and mobile communication.

Track Deadlift Exercise on Galaxy Watch

track deadlift exercise on galaxy watch objective create a native app for galaxy watch, operating on wear os powered by samsung, using health services to track deadlift exercise this app measures repetition count, calories burned, and time spent during the exercise overview health services provides a simple and unified way for accessing a wide range of health and wellness related data with health services api, you will no longer need to develop your own algorithms processing sensors data in order to compute metrics like heart rate, steps counts, distance, calories burned, and other more these are now accessible through health services embedded on wearables operating on wear os powered by samsung see health platform descriptions for detailed information set up your environment you will need the following galaxy watch4 or newer android studio latest version recommended java se development kit jdk 11 or later sample code here is a sample code for you to start coding in this code lab download it and start your learning experience! health track deadlift sample code 132 83 kb turn on developer mode and adjust its settings on your watch, go to settings > about watch > software and tap on software version 5 times upon successful activation of developer mode, a toast message will display as on the image below afterwards, developer options will be visible under settings tap developer options and enable the following options adb debugging debug over wi-fi turn off automatic wi-fi connect your galaxy watch to wi-fi go to settings > connection > wi-fi and make sure that wi-fi is enabled from the list of available wi-fi networks, choose and connect to the same one as your pc when successfully connected, tap a wi-fi network name, swipe down, and note the ip address you will need this to connect your watch over adb from your pc connect your galaxy watch to android studio in android studio, go to terminal and type adb connect <ip address as mentioned in previous step> when prompted, tap always allow from this computer to allow debugging upon successful connection, you will see the following message in android studio’s terminal connected to <ip address of your watch> now, you can run the app directly on your watch start your project after downloading the sample code containing the project files, open your android studio and click open to open an existing project locate the downloaded android project deadlift from the directory and click ok check dependency and app manifest in the dependencies section of gradle scripts > build gradle module app file, see the appropriate dependency for health services dependencies { implementation 'androidx health health-services-client 1 0 0-beta03' // } notesince the library might update from time to time, it is recommended to choose the version suggested by android studio in androidmanifest xml file, note the following <queries> element <queries> <package android name="com google android wearable healthservices" /> </queries> section with requests for necessary permissions <uses-permission android name="android permission body_sensors" /> <uses-permission android name="android permission activity_recognition" /> check capabilities to check what can be measured during an exercise, you need to check its capabilities go to app > java > com samsung sdc21 deadlift open the deadliftutil java file and navigate to the checkcapabilities method an inner class c definition implements the methods of the futurecallback interface within this definition, define the onsuccess method to retrieve the exercise type capabilities public void onsuccess exercisecapabilities result { objects requirenonnull result ;
