Answer 1

it seems that you are missing the intent filter. at least you didnt post it. can you have a look that you have the MAIN LAUNCHER like here? you need exactly one activity that matches this, if you want to be started from a homescreen.

<activity
        android:name="..."
        android:label="@string/app_name"
        android:theme="@style/AppTheme">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
</activity>
