Starting with Unity 2019.3, it builds the game into a library and splits the original main template into a launcher gradle file and a main gradle file.
It seems that the old way did not work well for new versions. Although in ideal world, we should find a way to support both versions below 2018 and above 2019, it seems that it is not that easy. With the fact that Unity itself only accepts plugins/assets built from 2019.4, I guess it is also a good chance to upgrade our minimal target to 2019.4 too.
I will continue to fix the related doc and requirement later.
This tries to solve #43
