No, a game is an entirely different beast.  
Specially when using OpenGL.  You start breaking things when you don't use the higher level classes and functions.  
Meaning, the lower you get, the more you'll have to write code to support different platforms.<p>The Android API is indeed standardized accross all platforms.  
Also, what's standardized is the java methods you use and the libraries provided.<p>Making a game, usually means you're rendering to hardware and you have to handle things like screen resizing, etc, yourself.<p>However, there isn't a standard UI definition yet like the iPhone has.  If that's what you mean.
