1) go to Run
> Run Configurations... > (Select your application on the left hand side) > (Click the "Target" tab
on the right hand side). 2) At the bottom there, you'll see 'Emulator
launch parameters'. In the 'additional
emulator command line options', add '-scale
0.75' (to make the screen 75% of full size)
Next time you start the emulator it will have scaled properly, hooray!
