Using Android's RenderScript, I am trying to restrict the range of the
allocation that is operated upon during a rsForEach call. According to the
documentation you can achieve this by passing in a rs_script_call structure
but whenever I try this the application crashes.
How is the rs_script_call structure correctly setup and passed into the
rsForEach call?
I have attached an adapted version of the HelloCompute Renderscript example
that demonstrates the problem. The minimum Android sdk version is set to 15
and therefore using the rsForEach call that takes 6 arguments.
Here is part of the log of the application running on a Nexus S with
Android 4.0.4:

I also posted this question over on StackOverflow (
