Android frontend support 
Hello, 

The Android libretro core seem to work well. 
However, i can't seem to run carts from a frontend. Launching from RA is OK, but launching from Daijisho shows the cart in a cart selector menu, not launching it. And i can't seem to find a way to launch the game from that. 

I haven't been able to add the .info file to the core folder, as changing the core folder from the default makes me unable to run the core, and default folder is not accessible without root. 

I'm using the 64 bit RA core on a Oneplus 7T. Will try some other devices soon.
