description: After Android/KMP app changes—build debug APK, install and launch on a real device; emulator only if user asked or no phone is connected

# Build, install, and run on device (after Android-related changes)
|
||
|
||
Whenever you change anything under **`app:android`**, **`app:shared`** (`commonMain` / `androidMain`), or **`utils:shared`** in ways that affect the Android app:
|
||
|
||
1. **Build** the debug APK: `./gradlew :app:android:assembleDebug` from the Android repo root. If `JAVA_HOME` pointing at Android Studio’s JBR fails, use a working JDK 17+ on the machine.
|
||
2. **Read Mobile MCP tool schemas** under the project’s MCP descriptors for `user-Mobile MCP` before calling tools (required).
|
||
3. **`mobile_list_available_devices`** — get all `id`s (and `name` / `type` if present).
|
||
4. **Use a real device by default.** Do **not** install or launch on an emulator **unless** the user **explicitly** asked to use the emulator, **or** no physical device is connected and **only** emulator(s) are available. Classify devices using `type != "emulator"` when reliable; if `type` is wrong or missing, treat as physical when the **name** does not look like an AVD (e.g. not `sdk_gphone`, not a generic emulator name). When one or more physical devices are available, install and launch **only** on those—**never** also push to emulators in the same step. When **no** physical device is connected, use every returned target (emulators).
|
||
5. For **each** chosen device `id`: **`mobile_install_app`** with `path` = absolute path to
|
||
`app/android/build/outputs/apk/debug/android-debug.apk`
|
||
in this repo.
|
||
6. For **each** same device: **`mobile_launch_app`** with `packageName` **`ru.fromchat.beta`**. The debug APK from `assembleDebug` uses `applicationIdSuffix = ".beta"` (`app/android/build.gradle.kts`), so the on-device package is **`ru.fromchat.beta`**, not `ru.fromchat`—`ru.fromchat` will fail to launch after a debug install. (Release / no-suffix id is `ru.fromchat`.)
|
||
7. **Smoke-test after launch** (when a device is online): use **`mobile_list_elements_on_screen`** on the chosen device, then exercise the flows your change touched (e.g. open **Settings**, drill into **Appearance**, **Notifications**, **Devices**, **Security** steps, **Account**, **About**—tap through and use **Back**). Fix any crash or obvious broken UI before finishing.
|
||
|
||
Also run **`:app:shared:compileKotlinIosArm64`** (and fix errors) when shared Kotlin changes should stay valid for iOS—either with the same Gradle invocation as in `general.mdc` or right after the Android APK build.
|
||
|
||
Skipping install/launch when **no** device is online is acceptable; do not skip the **Gradle build** after code changes.
