问题:
I am struggling a bit with the LocationListener in Android. I want to make an app that will get the current GPS location, and then afterwards sleep for a long time. A day or more. In this period of time i want the GPS notification icon to not show.
What i have now, is in the onLocationChanged a Thread.sleep(x) but this will keep the icon on in the sleep period. How can i do this, and is there a better approach than to use Thread.sleep?
Thanks in advance

You have to turn off the LocationManager completly for that. I did it in my App, where I only check the Location every 10 seconds, 'cause I found out, that the turning off saves a bit more battery power than a min_distance or min_time of the LocationManager.
Something like:
// Turning off mLocationManager.removeUpdates(gpsListener); mLocationManager = null; // Turning on again mLocationManager = (LocationManager) getApplicationContext().getSystemService(Context.LOCATION_SERVICE); mLocationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, GPS_MINTIME, GPS_MINDISTANCE, gpsListener);
The icon will disappear till the LocationManager is turned on again.

If you have overlays, think to disable the location on them too :
@Override protected void onResume() { Log.i("ProjetTEA", "onResumeMain"); if (mLocationListener != null) { mLocationOverlay.enableMyLocation(); mLocationManager = (LocationManager) getApplicationContext().getSystemService(LOCATION_SERVICE); mLocationManager.requestLocationUpdates(mBestProvider, 10000, 2, mLocationListener); } super.onResume(); } @Override protected void onPause() { Log.i("ProjetTEA", "onPauseMain"); mLocationOverlay.disableMyLocation(); mLocationManager.removeUpdates(mLocationListener); mLocationManager = null; super.onPause(); }
