When I make an Android Game with Godot engine, I need some features like analyze or payment, but there are not has. So I will make it and share it.
The plugins development with Godot 3.3 mono version. The submodule "godot-lib-3.3-xx" is Godot android build library from custom build template.
- run "gradle build" to compile and package all module;
- copy plugins//build/aar/-<debug|release>.aar
- and copy plugins//pluginName.gdap to godot custom build "plugins" folder
- config in Godot export configuration and enable plugin
- How to use some plugins? Read plugin README.
