[android] Cocos2dxGLSurfaceView, Cocos2dxRenderer no longer supported?

I’m fairly new to Cocos2d-x, and I’ve recently downloaded the 3.0 beta for Android application development. My current project has an existing Java Activity, and I was looking to embed a GLSurfaceView in the view hierarchy. It appears though that the classes that previously allowed this (Cocos2dxGLSurfaceView and Cocos2dxRenderer) are no longer included in the Android platform.

I’ve attempted to get these from an older version and make the necessary changes to get them to work in 3.0, although I have run into considerable issues with JNIHelper while doing so. Is running cocos2d-x in an embedded view no longer supported? Has anyone else attempted this, or would it be worthwhile for me to submit a pull request (once I have things working correctly of course - running a native activity full screen really isn’t an option for my current project.

Thanks in advance for any help or information)
