Android-Anwendung erscheint nicht in App-Menü

Question

Ich habe eine Anwendung, die die Google Maps und Google Location Services APIs verwendet. Ich kann die App über Android Studio ausführen, aber das App-Symbol wird nicht in meinem App-Menü angezeigt. Hier ist meine Manifest-Datei:

      <category android:name="android.intent.category.DEFAULT" /> 
     </intent-filter> 
    </activity> 

    <service 
     android:name=".FetchAddressIntentService" 
     android:exported="false"/> 

</application>
