Hi,
I'm developing a metronome application as a training exercise. I show
metronome beats changing the image (alternating a small gray and green
circle) of an ImageView posting a message to the main thread from a
worker thread. My questions:
1. is this a good solution or can you suggest me a better way to
implement this (like calling invalidate and putting the code within
ondraw)?
2. do you see any performance issues (I don't have a phone to test it)
changing images at, let's say, maximum 10 Hz? Should I move to use
openGL ES?

Thank you for your suggestions.
