Hallo,
ich habe Gestern mit der Programierung für Androide angefangen.
Nun bekomme ich es nicht hin das GPS anzusprechen, ich habe schon acht Tutorials zum Thema durch bekomme es aber nicht zum laufen.
Ich hoffe mir kann jemand weiterhelfen.
Androide 8.1
Manifest
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.INTERNET"/>
MainActivity
TrackerService
