Well, what do we have here? The android.view.KeyEvent class (that’s geek speak for keyboard controls in the code) in Android 2.3 has been updated to include support for what looks like Playstation phone controls. Included are new fields for buttons named A,B,C, L1, L2, R1, R2, select, start, X, Y, and Z. This looks like great news for all you gamers our there.
