Apps Screen size

[überfuzz]

I'm developing my first android application and I don't know what screen size to optimize for. Filling the screen is no problem, on the contrary I'm concerned that my app is going to be to dense or bloated.

Is there maybe a rule of thumb when it comes to how many touch buttons to place in a row?

Normaly you design your app in dp and it fits the alle screen sizes. You can check this with the emulator. If you see the Android menu, there normaly is a maximum of 3 buttons in 1 row.
