Android / RenderScript issues

[demantz]

I am completely new to RenderScript. I had a lot of issues getting it to work for me just because of the weak documentation. I made many mistakes and might still have errors in my code.

But it seems like RenderScript is also still not as stable as I thought at the beginning. So I start this issue to collect and discuss some links to Android bug reports which might affect this DSP library.
(Background for my research is the fact that the DSP library seems to crash on many different devices/android-images for no reason)
