问题 I've created my app using all the neccessary things to support different screen sizes/densities (relative layouts, dip etc.) I've created all the neccessary layout files (ldpi,mdpi etc) and images for this support. I've tested the app on all the available emulator skins using Eclipse, and they all appear like the should. I then tested this on a real device (Samsung Galaxy SII) and it looked great.
