I am trying to get Latitude and Longitude from the device using FusedLocationApi . If the location is turned off I am asking the user to turn on the location service through a dialog. Once the location service is turned on sometime I am getting the Longitude and Latitude . But sometime its returning Location as null. Here is the code to get the Latitude and Longitude using the FusedLocationApi. Problem comes when the user has to turn on the Location Service using the dialog
private void getLatLong() {
mGoogleApiClient = new GoogleApiClient.Builder(this)
// The next two lines tell the new client that “this” current class will handle connection stuff
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
//fourth line adds the LocationServices API endpoint from GooglePlayServices
.addApi(LocationServices.API)
.build();
}
@Override
protected void onPause() {
super.onPause();
overridePendingTransition(0, 0);
//Disconnect from API onPause()
if (mGoogleApiClient.isConnected()) {
LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, this);
mGoogleApiClient.disconnect();
}
}
@Override
public void onResume() {
super.onResume();
//Now lets connect to the API
mGoogleApiClient.connect();
}
@Override
public void onConnected(@Nullable Bundle bundle) {
if (mGoogleApiClient.isConnected()) {
Log.e("GoogleApiClient", "Connected");
settingsRequest();
}
}
private void settingsRequest() {
mLocationRequest = LocationRequest.create()
.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
.setInterval(10 * 1000) // 10 seconds, in milliseconds
.setFastestInterval(1000); // 1 second, in milliseconds
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder().addLocationRequest(mLocationRequest);
builder.setAlwaysShow(true); //this is the key ingredient
PendingResult<LocationSettingsResult> result = LocationServices.SettingsApi.checkLocationSettings(mGoogleApiClient, builder.build());
result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
@Override
public void onResult(LocationSettingsResult result) {
