This is deprecated. You can't switch on/off location programmatically. Better I suggest you to use the latest version of GooglePlayService. Using PlayService you can check at anytime whether the location is enabled or not. If it's not enabled then the AlertDialog to enable it. Without even leaving your application you can enable GPS. If it's not enabled then you can do whatever the operation you want to perform. You can find the more details from this post
Basically your Activity should implement ResultCallback<LocationSettingsResult>
And register PendingIntent like below,
PendingResult<LocationSettingsResult> result =
LocationServices.SettingsApi.checkLocationSettings(
mGoogleApiClient,
mLocationSettingsRequest
);
result.setResultCallback(this);
Now you have a onResult callback in that you can perform what you want to do
@Override
public void onResult(LocationSettingsResult locationSettingsResult) {
final Status status = locationSettingsResult.getStatus();
switch (status.getStatusCode()) {
case LocationSettingsStatusCodes.SUCCESS:
Log.i(TAG, "All location settings are satisfied.");
startLocationUpdates();
break;
case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
Log.i(TAG, "Location settings are not satisfied. Show the user a dialog to" +
"upgrade location settings ");
try {
// Show the dialog by calling startResolutionForResult(), and check the result
// in onActivityResult().
status.startResolutionForResult(MainActivity.this, REQUEST_CHECK_SETTINGS);
} catch (IntentSender.SendIntentException e) {
Log.i(TAG, "PendingIntent unable to execute request.");
}
break;
case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
Log.i(TAG, "Location settings are inadequate, and cannot be fixed here. Dialog " +
"not created.");
break;
}
}
