I need to make video player on Android that is able to play in slow motion and with different playback speeds. I still cannot find a native API or some code to do this. Does Android 2.2 - 2.3 support to video slow-motion and can we control the video playback speed?

You can try exploring libVLC for this. VLC player for Android is almost due. Check their website.
Check this thread that discusses how you do it.. http://forum.videolan.org/viewtopic.php?f=14&t=89296
libVLC developer documentation here with normal playback sample. You need to modify this sample to play the video frame by frame or slow down the frame rate.
