Question

I have the following code that crashes due to the Criteria being null.

For some reason the String best is null. Any ideas why?

private void startGPS() {
    Criteria criteria = new Criteria();
    criteria.setAccuracy(Criteria.ACCURACY_FINE);
    criteria.setPowerRequirement(Criteria.NO_REQUIREMENT);

    String best = locationManager.getBestProvider(criteria, true);

    Log.v(DEBUG_TAG, "Best provider: " + best);

    locationManager.requestLocationUpdates(best, 50, 0, this);

}

Answer 1

getBestProvider(criteria, true) will only return enabled providers. Since you request Criteria.ACCURACY_FINE you should get GPS, but if it is not enabled you’ll get null.
