I have started using the Google+ API for android, and I have created a sign-in application following this tutorial:

sommesh's answer is perfect, but for less code you can use "Public Static Method" like this:

public static GoogleApiClient mGoogleApiClient;
...
...
public static void signOutFromGoogle() {
    Auth.GoogleSignInApi.signOut(mGoogleApiClient).setResultCallback(
            new ResultCallback() {
                @Override
                public void onResult(Status status) {
                    //...
                }
            });
}

And on your other Activity call it:

Your_Google_Activity.mGoogleApiClient.connect();
btnSignOut.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {            
        Your_Google_Activity.signOutFromGoogle();
    }
});
