Source Code: / clientuser_net
While still on the topic of sanity checking, I also peppered my code with log.d() statements to trace through the activity life cycle of my activity classes.
e.g.
Log.d("AnimationActivity002", "A ClientUser.net Tutorial - Back Button Pressed");
I also take this opportunity to introduce overriding / detecting the back button key press onBackPressed() on android. I place a log in the overridden method to verify that we do press the back button.
I thinks thats it for sanity checking, we are free to move on and explore the game loop tutorial.
