Due to an inconsistency in Android 11 while using emulators,
InstallApp may fail with a permission denied error.
As a workaround, an app can be installed using
ADBCallRemote, for example:
ADBCallRemote("install -r /Path/to/App/AppName.apk") where /Path/to/App/AppName.apk is the path to the Android app file on the Android Gateway machine.
