We recently tested our application against android API level 14 and 15. We started development targeting minimal SKD Version 8 and excluding tablets (3.x).
With 2.x everything works well but when running the app on a 4.x droid it crashes at the point we're obtaining user's location.

Source:
public void onCreate() {
locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 300000, 500, locationListener);
super.onCreate();
}
According to the documentation an IAE is thrown if provider or listener is null
.
However I logged the provider and listener. (the latter via toString() ) and they're not null.
Coming from this question I found an open issue. However I was wondering how people that are more confident with ice cream sandwich request user's coordinates.
The tutorial I know of uses the same approach described above.
