Resolution settings.

the BEST way is to follow Android guidelines and make resources in MDPI, HDPI, XHDPI, and have your app scale to the screen size... but that takes a hell of a lot of work, especially with the 1-person development studios that use Clickteam products, and can be very resource and memory intensive with the limitations of MMF2's software.

So yeah i guess i dont really have an answer. So far in my tests I'm mostly resizing the app window to fit (with black bars), and some apps i have resize to fit and then scale the frame, repositioning objects if needed. The second option i mentioned looks nicer but can be difficult depending on the app.

I build them at 1136x960 (iPhone 5 resolution) and have them crop to fit horizontally. Some people like to build at 800x480 as that's the old phone standard.

I build all mine ~850x480, gives for a nice effect (landscape) and can be up/downscaled to perfection both on a phone or tablet.
