Actually i created a application to show the nearest Fuel station, so i use the FusedLocationApi for that, and in the code first i check the use location is enabled or not, If no than i build GoogleClient and call setingsrequest() function and if location is ON than application works perfectly but when location OFF than aaplication is crash.. please check logs
logs :
