+
+## Installation
+
+```sh
+yarn add @react-native-community/cli-platform-android
+```
+
+## Commands
+

+
+Specify an `applicationIdSuffix` to launch after build.
+
+#### `--main-activity <string>`
+
+> default: 'MainActivity'
+
+Name of the activity to start.
+
+#### `--deviceId <string>`
+
+builds your app and starts it on a specific device/simulator with the given device id (listed by running "adb devices" on the command line).
+
+#### `--no-packager`

+
+#### `--interactive`
+
+Manually select a task and device/simulator you want to run your app on.
+
+> [!WARNING]  
+> This flag is running `./gradlew tasks` under the hood, which might take some time for more complex apps. If that affects your project, consider using `--mode` and `--deviceId` flags instead.
