see this post: Google Maps and apps with a map have different current positions

Are you talking about your own MapView with your application or with the Google Maps application? On your own map, use the network provider and gps provider to get the location. Gps only works outdoors under free skies and is more accurate, while the network provider works indoors, but is less accurate.

API 9 setAccuracy

lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_HIGH);  
lm.getBestProvider(criteria, true);

ACCURACY_HIGH 100
ACCURACY_MEDIUM 100 - 500
ACCURACY_LOW 500
