Can't same bitmap to cameraRoll in Android 4

Question

I am using the following code to allow users to save drawings to the mobile device's cameraRoll:

	var cameraRoll:CameraRoll = new CameraRoll();
	var bitmapData:BitmapData = new BitmapData(stage.stageWidth,stage.stageHeight);
	bitmapData.draw(MovieClip(root).stage);
	cameraRoll.addBitmapData(bitmapData);

The code works as expected on tested devices including iOS 5 and 6 with an iPhone 4 and iPad 3, and various flavors of Android 2.x and 3. It does not, however, work on Android 4.x (tested with 4.0, 4.1 and 4.2 on a Galaxy Nexus). The results are the same compiled using Adobe AIR 3.2 and 3.4. Is there some magic code I should be using to save images to Android 4?

My app is being compiled on Windows 7 using Adobe Flash Professional CS6 (12.0.2.529).

As a matter of fact, I just did. It turns out that I needed to select the "WRITE_EXTERNAL_STORAGE" permission. Android 4 must count writing to the cameraroll as accessing external storage where Android 2 does not.

Did you have any joy solving this? I am also experiencing trouble trying to save to the camera roll on my Nexus 7 with Android 4.1.2

Published app with Flash CS6 and AIR 3.4

My code works fine on iPad.

Would be great to know if it is something I am doing wrong or if it is a bug?

Thanks

UPDATE: The same code works fine on Android HTC Desire Phone with Android 2.x

Have tested compiling with Air 3.5 and the problem still exists
