I download the source code of ‘SDL-release-2.26.3’.
I am working on Windows 10.
I see there is an ‘android-project’ folder under the source code root.
When I use Android Studio open the android-project, I got the error:

BUILD SUCCESSFUL in 25s
My Android Studio’s Build button can’t be use, is in gray state.
I think may be I need do some thing to build SDL2 lib first, and then build the android-project.
But I don’t know where to find the docs for build the android-project.
I want to build the andorid-project because I think it is a completely android project sample.
Is the android-project folder for that reason?
I want to got a template to do the begin of my SDL2 dev.
