There are few things worse than broken library implementations, so I thought I'd post a warning for others.

Qualcomm's (present in most android devices) implementation of glDeleteTextures raises GL_INVALID_VALUE if you try to delete zero textures, in violation of the specification.

Annoying yes, but then why would you do that anyway?  Roll Eyes

Yeah, happily it's easy to avoid once you know you have to.
The context: recreating textures after they may possibly have been zapped when the activity is in the background, so it was a glDeleteTextures( textureList.size(), ...) in onSurfaceCreated(). Obviously at startup I don't have any textures loaded yet, so it instantly raises GL_INVALID_VALUE.

In other news, today I learned that annotations with primitive array values cause pre-froyo Dalvik to segfault. Every time.
