We can use broadcast receiver to listen app update.

Receiver

class AppUpgradeReceiver : BroadcastReceiver() {

  @SuppressLint("UnsafeProtectedBroadcastReceiver")
  override fun onReceive(context: Context?, intent: Intent?) {
    if (context == null) {
        return
    }
    Toast.makeText(context, "Updated to version #${BuildConfig.VERSION_CODE}!", Toast.LENGTH_LONG).show()
  }

}

Manifest

It doesn't work while debug. So you have to install to manually.

1. Increase the versionCode in your app-level build.gradle (so it counts as an update).
2. Click Build -> Build Bundle(s) / APK(s) -> Build APK(s), and select a debug APK.

3. Run following command in the terminal of Android Studio:

   adb install -r C:\Repositories\updatelistener\app\build\outputs\apk\debug\app-debug.apk
