Screen measures

I’m planning a game for android. As settings for the screen I’m using 1024 X 600 (for my samsung tablet Tab2) if I try the game on another device Android phone the size of the frame will be automatic?

Yes, if you don’t force the resolution with code it will be automatically the device’s native resolution. (But the UI needs to be correctly aligned/scaled when necessary on different resolutions)
Don’t know what you mean with ‘settings for the screen’ because there isn’t resolution ‘settings’ for Android…
