Changing screen brightness in Android emulator
<p>Can screen brightness changes be tested in the Android emulator?  I've tried various examples that all use the following code snippet:</p>

<pre><code>WindowManager.LayoutParams lp = window.getAttributes();
lp.screenBrightness = (*some float percentage*);
window.setAttributes(lp);
</code></pre>

<p>But I don't see any change in brightness in the emulator.  I've tested it in cupcake and 2.2.</p>
