Right, the situation is as follows;
We have developed an app that checks the location of the user every 5-10 minutes for location specific content. To do so, I've created a Service to stick to the background (so it can update even when the app isn't directly in the foreground) in which a LocationController is created to check the latest known location. When it's finished, it cleans up and the location is sent to a database (which is a necessity for this concept).
This all works fine, as long as I check the location with GPS_PROVIDER. However, when I switch it around to NETWORK_PROVIDER, it may check the location once more before dying completely.
I've tried multiple options to prevent this problem, but nothing seems to be working with the update service when I swap that 1 setting.
Here are a few snippets which should be relevant to the service:
UpdateService:
@Override
public void onCreate() {
super.onCreate();
Log.d("Debug", "Created service");
PowerManager mgr = (PowerManager)getSystemService(Context.POWER_SERVICE);
wakeLock = mgr.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "MyWakeLock");
wakeLock.acquire();
IntentFilter filter = new IntentFilter();
filter.addAction(UPDATE_ACTION);
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.d("Starting", "Starting Service");
mNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
mAlarmManager = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
Intent i = new Intent(UPDATE_ACTION);
alarmManagerPendingIntent = PendingIntent.getBroadcast(this, 0, i, 0);
alarmManagerPendingIntent.cancel();
mAlarmManager.cancel(alarmManagerPendingIntent);
mAlarmManager.setInexactRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
AlarmManager.INTERVAL_FIFTEEN_MINUTES,
AlarmManager.INTERVAL_FIFTEEN_MINUTES,
alarmManagerPendingIntent);
mLocationController = new LocationController(this, this);
updateHandler = new Handler();
return START_STICKY;
}
LocationController:
private LocationListener locationListener = new LocationListener() {
private boolean didSendLocation;
public void onLocationChanged(Location location) {
mLastLocation = location;
mCallback.locationUpdate(location,false);
didSendLocation = true;
}
public void onStatusChanged(String provider, int status, Bundle extras) {
Log.d("Debug", "Status changed: "+status);
Location _lastLocation = mLocationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
Log.d("Debug", "Last location: "+_lastLocation);
if(!didSendLocation)
{
mCallback.locationUpdate(_lastLocation,false);
}
didSendLocation = false;
}
public void onProviderEnabled(String provider) {
Log.d("Debug", "Provider Enabled");
}
public void onProviderDisabled(String provider) {
Log.d("Debug", "Provider disabled");
}
};
public LocationController(Context mContext, LocationControllerCallback callback) {
this.mContext = mContext;
mCallback = callback;
Log.d("Debug", "Created LocationController");
mLocationManager = (LocationManager) mContext.getSystemService(Context.LOCATION_SERVICE);
mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 300000, 100, locationListener);
mLastLocation = mLocationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
mCallback.locationUpdate(mLastLocation,true);
}
So, the code works as it is now, but when I swap:
mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 300000, 100, locationListener);
with
mLocationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 300000, 100, locationListener);
It will no longer update. Any ideas?
I've solved the problem by switching to the Google Play Fused Location provider. A more detailed post around this can be found here: https://stackoverflow.com/a/19282976/3532181
Sadly the standard network provider just seemed too unreliable when it came to updates, ranging from an update within 8 minutes to hours before a new update was sent to the app.
