Robert, yes, there is really nothing more!
I have already tested with a Thread.sleep(18). This does not change the behaviour. Actually it makes other things worse. Events don't get handled in time: If you don't touch the screen for a while it's get dimmed. If I put in the Thread.sleep(...) and touch a (dimmed) screen it can take up to 3 and more seconds until it gets bright again. Without the sleep() it is reacting instantly. So I have abonomed Thread.sleep(...) and event.recycle(). I think we have to live with this behaviour. But it would be good if another one can confirm this. Especially if it is a problem with the Nexus One or Android 2.1. Can someone post its Java "Framerate meassurement code" and post it? Mine is in a "Game-Framework" (which I can not share) written in C++. With this I can prepare a simple testcase. But as I told the test is really simple: Take the code from: http://android-developers.blogspot.com/2009/04/introducing-glsurfaceview.htmland add the log output of the frame rate.
