We are going to move a product from Unity 4 to 5 and would like to build it with IL2CPP option.
Our game supports from Android 4.1.
If someone knows it, it help us a lot.
Thanks,
Yes IL2CPP on Android should work on all Android versions. If you are targeting JellyBean+ (Android 4.1+) - this is even better 
If you face any issues specific to IL2CPP on Android - don’t hesitate to share it with us.
