I have installed the official Samsung Galaxy S2 skin thanks to another stackoverflow question, in Eclipse.
The problem I have is that it doesn't render my app anywhere near the resolution of the actual device when running in the Emulator, surely this is the point of using the skin.
Please see the screenshots and settings I'm using, where am I going wrong?
Emulator output - API 11
Emulator output - API 15

AVD settings - automatically generated by the skin
Try changing Abstracted LCD density hardware argument from 300 to 218 ppi.
In AVD Manager, select your Galaxy SII emulator, click the "Start..." button and then in the Launch Options dialog configure the display as follows:
I see that your AVD target is Android 3.0 but the GUI on your physical device looks different. Make sure to test using an emulator with the same Android version and theme than your real phone.
