Error running phonegap camera sample

Hi I tried to run the phonegap camera sample on my Sony Xperia E device. The app is launched in the device correctly, however when I hit the Capture Photo button I got and alert box says "Failed because: class not found". In the LogCat view in the eclipse I found these error logs:

I/System.out: Error adding plugin org.apache.cordova.CameraLauncher.
D/PluginManager: exec() call to unknown plugin: Camera

I strictly follow the documents and already added the following items in config.xml:

<feature name="Camera">
    <param name="android-package" value="org.apache.cordova.CameraLauncher" />
</feature>

I've also running successfully this lines from my android-sdk folder:

cordova plugin add https://git-wip-us.apache.org/repos/asf/cordova-plugin-camera.git

I've cleaned the project in eclipse several times and running it several times, all lead to the same result. Anyone has any idea where I was wrong?

thx...

PS

The index.html:

Change org.apache.cordova.CameraLauncher to org.apache.cordova.camera.CameraLauncher in config.xml.

That worked for me.

I just checked this git(git-wip-us.apache.org/repos/asf/cordova-plugin-camera.git) from the Camera API documentation and its src/android/CameraLauncher.java file's package name is com.apache.cordova.camera if your source code is also using this package name, then ur config file value should be changed to org.apache.cordova.camera.CameraLauncher
