<h2 id="TaskVerifyProvider">Verify the Location Provider is Enabled</h2>

<p>Some location providers such as the GPS can be disabled in Settings.  It is good practice to check whether the desired location provider is currently enabled by calling the {@link android.location.LocationManager#isProviderEnabled(java.lang.String) isProviderEnabled()} method.  If the location provider is disabled, you can offer the user an opportunity to enable it in Settings by firing an {@link android.content.Intent} with the {@link android.provider.Settings#ACTION_LOCATION_SOURCE_SETTINGS} action.</p>

<pre>

@Override

protected void onStart() {

    super.onStart();

    // This verification should be done during onStart() because the system calls

    // this method when the user returns to the activity, which ensures the desired

    // location provider is enabled each time the activity resumes from the stopped state.

    LocationManager locationManager =

            (LocationManager) getSystemService(Context.LOCATION_SERVICE);

    final boolean gpsEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);

    if (!gpsEnabled) {

        // Build an alert dialog here that requests that the user enable

        // the location services, then when the user clicks the "OK" button,

        // call enableLocationSettings()

    }

}

private void enableLocationSettings() {

    Intent settingsIntent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);

    startActivity(settingsIntent);

}
