hello
I am using godot 3.1.1 and tried to optimize my game and reduce it’s size. For that I downloaded the stable release source code and built the project for android .First with debug and release and then with only release(by creating another debug.keystore file).Both the times the size was unbelievably small but when I tested the game it didn’t start and gave ‘unfortunately ,game has stopped’.Can anyone please give any advise on this.I have been trying optimization for a long time and I’m stuck at it.
