In my new game I am trying to have the g+1 and google Plus circles. I do find lot of tutorial in Android but not even one with Android + LibGdx for my purpose.
The main problem I face in having the g+1 button is the annotation bubble. The bubble shows the number of persons who has already +1ed the app. How to get the annotation value ?
Is there is a guide for implementing the g+1 and google circle feature in LibGdx ?
Generally all game engines using Android OpenGL use GLSurfaceView (or general SurfaceView). This view like all other views (EditText, Button, etc) is of type regular Android views. Therefore, you can arrange it
along side other views in regular Andorid layout views (e.g. LinearLayout, RelativeView).
In your case, you can use FrameLayout or RelativeLayout to overlay this two views (LibGDX's SurfaceView and the Google+1 view).
LibGDX view:
View libgdxView = initializeForView(new GameWorld(this), false);
G+1 button: Adding a Google +1 button in Android App
So, similar to question below, you can add this G+1 button wherever you like in the screen.
Can I have Android Views overlayed on top of the libgdx GL surface?
