Is there a simple way to compile GeckoView for Android ?

[Lua12138]

I want to use GeckoView in a customized Android system. Because the Android version is API19, and the new version released by Mozilla requires a minimum of API21.

So I hope to compile GeckView myself and try to find out which functions require API21 (I can cut them off)

However, by looking at the documents, I found that it is very difficult to compile GeckoView, and I need to obtain mozilla-central code, which is very large, and there are many contents coupled in mozilla-central compiled code (such as JDK/Android SDK/git-cinnabar and Rust, etc.).
