Is there a way to manipulate lcd backlight in android?
<p>In my application, I need to change the screen backlight for testing. I am atm using API 15 with the external jar Hardware09.jar which has a method called setScreenBacklight(int value).</p>

<p>However when I tried to use it I have an error message like this:</p>

<pre><code>01-01 00:48:24.570: E/AndroidRuntime(2171): java.lang.NoSuchMethodError: android.os.IHardwareService.setScreenBacklight
</code></pre>

<p>I dont know what to do in that situation. Is there a way to use that external jar or are there any other ways to control backlight?</p>

<p>Thanks in advance.</p>

<p>This is the screenshot of java build path.</p>
