comment Collisions reflecting ball velocities incorrectly
FWIW, a full solution can be found in code.google.com/p/android-breakout . The collision detection code is extensively commented (start in moveBall(); most relevant bit is findFirstCollision().).

comment Java Buffers and OpenGL ES 2.0 (Android)
cf. "texture swizzling" and related topics. The format of the image loaded from disk may be suboptimal for access by the hardware, so being able to rewrite the texture can provide significant performance improvements. So not only would avoiding the copy be a restrictive API design for non-UMA systems, it could also cause a performance hit.

comment Android Loop : Draw Loop : How to pull off smooth FPS?
The easiest way to check for GC-induced problems is to watch the logcat output. If you see a lot of GC messages from Dalvik, you need to find a way to reduce object churn. (These are logged at "debug" level.)

comment Formula for converting ratio of current device to target device
You can see it in a GLSurfaceView implementation here; it's essentially the same computation, but not as concise: code.google.com/p/android-breakout/source/browse/src/com/…

comment Where to run logic update in openGL ES?
Example of a game that uses this structure: code.google.com/p/android-breakout . Some discussion about the one-vs-two thread approaches is in the supporting docs, and also here: stackoverflow.com/questions/14077403/…
