Hallo, I"m working right now on a 3D application and I would like to offer the app on an android phone as well as on the dektop. Do the Android platform have a high level API for 3D applications like Java3D or JME? If not, do you all really developing only with the low level OpenGL ES?

You could start writing your own openGl ES renderer, and if it's good, I'd use it .

I really don't wish to program picking, collision detection, bounding shperes and most importantly a scene graph by my self. Are there no plans to port (for example) java3d to OpenGL ES?

if android really takes off, im sure there will be something eventually.

If your lucky there will be a JPCT port out: http://www.jpct.net/forum2/index.php/to ... g8265.html
Though the developer is currently stuck with the slow emulator.

For the one that interested, JME is likely be ported to the android platform. See Joshua's Blog for more details about this effort.

One short question, if I start programing with JOGL for the desktop application how hard is it to port it later to the android platform? Android uses OpenGL ES 1.0 which corresponds to OpenGL 1.3, so if I only use OpenGL 1.3 features, how hard will it be?

There are some other limitations too. You can only use vertex arrays for example, for a complete list of such limitations go to the khronos opengl es web site.
