Renderscript support

Question

Does the GDK support Renderscript? I wanted to run some image processing algorithms on Glass's Camera. However, the process crashes with a SIGSEGVfault.

Here is the stack trace:

Answer 1

There may be another problem with your code — this Renderscript tutorial works on Glass, so if you can investigate how that demo differs from your code, we might be able to track down the problem.

Answer 2

I don't have a definite answer, but my RenderScript application failed on the Glass with a similar error: Fatal signal 11 (SIGSEGV) at 0xdeadbaad (code=1).

I think the problem may be that the Glass filesystem doesn't allow for transferring object files (*.o). I get an error similar to your 'Unable to open /data/data/.../oilpaintingeffect.o in read mode. (reason: No such file or directory)'
