Fused location ошибка

I was requesting the location updates with the help of

LocationServices.FusedLocationApi.requestLocationUpdates(googleApiClient, 
locationRequest, locationListener);

But As I tried to mention this on a swtich onClickListener , it crashed. However there was no error thrown Android Studio itself.

I already have added permission to request Fused Location, coarse Location and Internet as part of this function. I even tried to connect the google Api client before requesting the Updated
Like.,

if(googleApiClient.isConnected){
LocationServices.FusedLocationApi.requestLocationUpdates(googleApiClient, 
locationRequest, locationListener);
}else{
buildGoogleApiClient();
}

But I could not get the error resolved.
removing the location request with Fused Location Provider Api is also causing the app to crash.

My Manifest file have codes as given below. As you can see i already have requested the permissions requred

My XML File is as
