        startActivity(intent);

    } else {

    }
}


@Override

}
public void onStart(){
    OptionalPendingResult<GoogleSignInResult> opr = Auth.GoogleSignInApi.silentSignIn(mGoogleapiclient);

    if (opr.isDone()) {
        // If the user's cached credentials are valid, the OptionalPendingResult will be "done"
        // and the GoogleSignInResult will be available instantly.
        Log.d("gmailsignup", "Got cached sign-in");
        GoogleSignInResult result = opr.get();
        handleSignInResult(result);
    } else {
        // If the user has not prevIoUsly signed in on this device or the sign-in has expired,
        // this asynchronous branch will attempt to sign in the user silently.  Cross-device
        // single sign-on will occur in this branch.
        opr.setResultCallback(new ResultCallback<GoogleSignInResult>() {
            @Override
            public void onResult(GoogleSignInResult googleSignInResult) {
                handleSignInResult(googleSignInResult);
            }
        });
    }
}
}
