The app showcases the different ways to view\ninformation at a glance on Wear OS devices, and introduces some best practices\nfor developing apps on the platform.\n\nThis guide builds upon some prior knowledge about the Android platform and the\n[Android Studio IDE](/studio). If you're completely new to Android, [create an app\nusing this codelab](/codelabs/basic-android-kotlin-compose-first-app#1). To learn more about Android Studio's capabilities, visit\nthe [Meet Android Studio](/studio/intro) page.\n| **Note:** To use the latest system images that are available for the emulator, install Android Studio Hedgehog or later.\n\nCreate a Wear OS app\n--------------------\n\nAfter you download and install the latest version of Android Studio, complete\nthe \"new project\" wizard:\n\n1. Open Android Studio, and then go to **File \\\u003e New \\\u003e New Project** . The **New Project** window appears.\n2. In the **Templates** pane, select **Wear OS** . Then, in the main pane, select **Empty Wear App**.\n3. Name your project, and then click **Finish**. Android Studio downloads the necessary dependencies and builds the initial version of your project.\n4. Go to [**Tools \\\u003e SDK Manager**](/studio/intro/update#sdk-manager), click **Show Package Details**, and\n install the following packages:\n\n - **Android 15.0 (\"VanillaIceCream\")** (API level 35-ext15), which includes the **Wear OS 5.1 ARM 64 v8a System Image** and the **Wear OS 5.1 Intel x86 Atom_64 System Image**.\n - **Android 14.0 (\"UpsideDownCake\")** (API level 34), which includes the **Wear OS 5 ARM 64 v8a System Image** and the **Wear OS 5 Intel x86 Atom_64 System Image**.\n - **Android 13.0 (\"Tiramisu\")** (API level 33), which includes the **Wear OS 4 ARM 64 v8a System Image** and the **Wear OS 4 Intel x86 Atom_64\n System Image**.\n\n | **Note:** The latest stable version of Wear OS, Wear OS 5.1, is based on Android 15.\n\n To close the SDK Manager, click **OK**.\n\nYou're now ready to run your first app on Wear OS.\n| **Note:** By default, the **New Project** wizard creates a standalone, independent Wear OS app that doesn't need to connect to another device in order to run. \n|\n| A Wear OS app should work independently of a phone app, giving users the greatest flexibility in their choice of phones. If your app's experience or complexity requires you to connect to a phone, see the guide on how to [connect\n| a watch to a phone](/training/wearables/get-started/connect-phone).\n\nRun an app on the emulator\n--------------------------\n\nThe easiest way to run your first Wear OS app is to configure an emulator.\n| **Note:** If you plan to make your Wear OS apps available in China, also visit the [Create Wear OS apps for China](/training/wearables/apps/creating-app-china) page.\n\n### Configure an emulator\n\nTo configure an emulator in Android Studio, complete the following steps:\n\n1. In the SDK Manager, Open the **SDK Tools** tab. Confirm that you have the latest version of **Android SDK Platform-Tools**. Close the SDK Manager.\n2. Go to **Tools \\\u003e Device Manager**.\n3. Select **Create (+)** . The **Virtual Device Configuration** wizard appears.\n4. In the **Category** pane, select **Wear OS** and choose a hardware profile, such as **Wear OS Small Round** . Click **Next**.\n5. For system images used outside of China, select the **UpsideDownCake**\n release name. This release targets Android 14.0 (Wear OS 5). For\n system images used in China, select the **R** release name. This release\n targets Android 11.0 (Wear OS 3). If you don't already have a Wear OS 5\n system image installed that matches your device definition, click\n **Download** next to the **Release Name** to get it. Click **Next**.\n\n **Note:** System images for the Wear OS emulator include notices of\n third-party files and source code. You can view third-party notices for a\n particular system image by opening the `NOTICE.txt` file, which\n is in one of the following directories:\n - `$ANDROID_HOME/system-images/android-`\u003cvar translate=\"no\"\u003eAPI_VERSION_NUMBER\u003c/var\u003e`/android-wear/`\u003cvar translate=\"no\"\u003eABI\u003c/var\u003e for emulators used outside of China.\n - `$ANDROID_HOME/system-images/android-`\u003cvar translate=\"no\"\u003eAPI_VERSION_NUMBER\u003c/var\u003e`/android-wear-cn/`\u003cvar translate=\"no\"\u003eABI\u003c/var\u003e for emulators used in China.\n6. You can keep the default value for all the settings on this screen, unless\n you want to customize your emulator. Click **Finish**.\n\nFor more information about using emulators, see the guide about how to [run apps\non the Android Emulator](/studio/run/emulator).\n\n### Open the app in the emulator\n\n1. Go to **Run \\\u003e Select Device**. Choose the emulator that you just created.\n2. In the Android Studio toolbar, click **Run** . The emulator starts and opens your app.\n3. After a few moments, you should see a \"Hello...\" message in the emulator.\n\n### Test Bluetooth audio using the emulator\n\nOn system images the run Wear OS 4 or higher, the emulator supports emulated\nBluetooth, which lets you [test Bluetooth audio](/training/wearables/apps/test-bluetooth-audio) across several use cases.\n\n### Recent system images only support 64-bit architectures\n\nThe emulator system images for Wear OS 4 and higher only support these 64-bit\narchitectures: `x86-64` and `arm64-v8a`. If you know or suspect that your app\nuses native code (that isn't written in the Kotlin or Java programming\nlanguages), check that your app includes both 32-bit and 64-bit native\nlibraries.\n\nLearn more about how to [support 64-bit architectures](/google/play/requirements/64-bit).\n\nRun an app on a physical watch (optional)\n-----------------------------------------\n\nRunning and debugging your app on an actual watch lets you better evaluate the\ntotal user experience. This is particularly important if your app relies on\nspecific hardware, such as sensors or a GPU.\n\nTo run an app on a physical watch, prepare the device for testing, and then\nconnect it to your development machine.\n\n### Prepare watch for testing\n\nTo prepare your watch for testing, enable ADB debugging by completing the\nfollowing steps.\n\n1. On the watch, open the **Settings** menu.\n2. Go to the bottom of the menu. If no **Developer options** item appears, complete the following sub-steps. Otherwise, continue to the next step.\n 1. Tap **System \\\u003e About** or **System \\\u003e About \\\u003e Versions**.\n 2. Find the **Build number** item and tap it seven times. If your watch is protected by a PIN or pattern, enter it when prompted to do so.\n3. From the **Settings** menu, tap **Developer options**.\n4. Enable the **ADB debugging** option.\n\n### Connect watch to development machine\n\nSome watches let you connect over USB. Others require a wireless connection.\n\n#### Set up a wired connection over USB\n\nConnect the watch using the following steps:\n\n1. Using a USB cable, connect the watch to your development machine.\n2. On the watch, enable **Always allow from this computer** , and then tap **OK**.\n\n#### Set up a wireless connection\n\nIf your watch lacks a USB port, learn how to [connect a watch using Wi-Fi or\nBluetooth](/training/wearables/apps/debugging).\n\n### Install a specific version of Wear OS (optional)\n\nIf your app's test case depends on a specific version of Wear OS, you can flash\na software image onto watches that support a USB (wired) data connection. For\nexample, you can flash a [factory image](https://developers.google.com/android/images-watch) or a [full OTA image](https://developers.google.com/android/ota-watch)\nonto a Google Pixel Watch 3 or Google Pixel Watch 2 device.\n\n### Open the app on the watch\n\n1. Go to **Run \\\u003e Select Device**. Choose the watch that is connected to your machine.\n2. In the Android Studio toolbar, click **Run** . The emulator starts and opens your app.\n3. After a few moments, you should see a \"Hello...\" message appear on the watch.\n\nRecommended for you\n-------------------\n\n- Note: link text is displayed when JavaScript is off\n- [Integrate custom C/C++ build systems using Ninja (experimental)](/build/cxx-ninja)\n- [Vulkan validation layers on Android](/ndk/guides/graphics/validation-layer)\n- [Release notes](/training/wearables/versions/5/release-notes)"]]
