title: How to debug in .rs file with RenderScript?
body: <p>I want to add some log in fall.rs (in:packages\wallpapers\Basic\src\com\android\wallpaper\fall). And the code is like this:</p>
  
  <p>int root(void) {</p>
  
  <pre><code>rsDebug("===========root==================",0);
  rsgClearColor(0.f, 0.f, 0.f, 1.f);
  ...
  </code></pre>
  
  <p>}</p>
  
  <p>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".</p>
