3D Scene Creation & SDK

Question

I am looking to create a 3D scene for Android devices.

I do not know where to begin, so help would be appreciated.

I, basically, need to create the 3d scene (what to use?) allow objects to be added or removed from the scene, and have an SDK to load and display the scene on an Android device.

I know all this would be ideal in a single resource, but I know I will have to adapt function calls to JNI/Android OpenGL.

Any help for how to get started or where to begin research would be appreciated.

PS. I will use a viewport to look into the scene from different perspectives.
