Mein Versuch GPS Daten aus einem Service heraus zu laden schlägt leider immer fehl.
dieser Betrifft die Zeilen:
lmGPS.requestLocationUpdates(LocationManager.GPS_PROVIDER,0,0,llGPS);
lmNET.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,0,0,llNET);
in folgendem Code
Wie muss die Abfrage sonst gestaltet werden?
Code:
Fehler beim GPS auslesen: java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare()
Fehler beim NET auslesen: java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare()lmGPS.requestLocationUpdates(LocationManager.GPS_PROVIDER,0,0,llGPS);
lmNET.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,0,0,llNET);
