Thanks in advance...

That may not be possible. However you can look at these links and learn how to provide different images(pixels and density), layouts and further on. It may not be possible to make a userinterface on a low level density screen the same way as a high density screen and then you can target different layouts to different phones e.g.

Check the android developer site, mainly the following
