Here, I'm integrating Sign in with Facebook and G+ in my project which is working fine if I integrate to each in individual activities but if I integrate to both of them in the same activity I start getting an error in the code of G+. For more I'm going to paste my code and error. My LoginActivity where I'm integrating to both of them together is
