How to debug in .rs file with RenderScript?

Question

I want to add some log in fall.rs (in:packages\wallpapers\Basic\src\com\android\wallpaper\fall). And the code is like this:

int root(void) {

rsDebug("===========root==================",0);
rsgClearColor(0.f, 0.f, 0.f, 1.f);
...

}

But my device can't print any log when I set live wallpaper. Although there are many examples about "rsDebug", but I can't find what's wrong when I use "rsDebug".

Answer 1

What kind of device is this (and what version of Android is it running)? Also, rsDebug logs at the "D" (Debug) level, so if you are filtering logcat, you might just not be seeing it. Do you see any messages tagged as "D"?
