/**
* Runs the first Activity shown in the top-level launcher as determined by its Intent filters.
*
* Android provides a component-based architecture, which means that there is no "main" function which serves as an
* entry point to the APK. There's an homogeneous collection of Activity(es), Service(s), Receiver(s), etc.
*
*
* The Android top-level launcher (whose purpose is to allow users to launch other applications) uses the Intent
* resolution mechanism to determine which Activity(es) to show to the end user. Such activities are identified by at
* least:
*
* - Action type:
android.intent.action.MAIN
* - Category:
android.intent.category.LAUNCHER
*
*
* And are declared in AndroidManifest.xml as such:
*
* <activity android:name=".ExampleActivity">
* <intent-filter>
* <action android:name="android.intent.action.MAIN" />
* <category android:name="android.intent.category.LAUNCHER" />
* </intent-filter>
* </activity>
*
*
* This {@link Mojo} will try to to launch the first activity of this kind found in AndroidManifest.xml. In
* case multiple activities satisfy the requirements listed above only the first declared one is run. In case there are
* no "Launcher activities" declared in the manifest or no activities declared at all, this goal aborts throwing an
* error.
*
*
* The device parameter is taken into consideration so potentially the Activity found is started on all attached
* devices. The application will NOT be deployed and running will silently fail if the application is not deployed.
*
