A simple way to authenticate with Google and Facebook using OAuth 2.0 in Android

How To Use

Google

Login

// Use a Web credential instead of Android credential
GoogleOAuth.login(this)
    .setClientId(Credentials.GOOGLE_CLIENT_ID)
    .setClientSecret(Credentials.GOOGLE_CLIENT_SECRET)
    .setAdditionalScopes("https://www.googleapis.com/auth/plus.login https://www.googleapis.com/auth/user.birthday.read")
    .setRedirectUri(Credentials.GOOGLE_REDIRECT_URI)
    .setCallback(new OnLoginCallback() {
        @Override
        public void onSuccess(String token, SocialUser user) {
            Log.d("Google Token", token);
            Log.d("Google User", user+"");
        }
        @Override
        public void onError(Exception error) {
            error.printStackTrace();
        }
    })
    .init();

Logout (revoke token)

GoogleOAuth.logout(this)
    .setToken(currentToken)
    .setCallback(new OnLogoutCallback() {
        @Override
        public void onSuccess() {
            
        }
        @Override
        public void onError(Exception error) {
            
        }
    })
    .init();

            Log.d("Facebook User", user+"");
        }
        @Override
