Android Studio - How to make modules inside a subdirectory?

Question

Suppose that I had 3 modules: mod1, mod2 and mod3.

In normal case, the file system hierarchy should be:

[android_root_dir]
build.gradle # list this file          


        

Answer 1

My project struct

Coding
   app
   push-dir
     coding-push
     push-xiaomi
   setting.gradle

setting.gradle file

// need repeat declarative, i think it's bug
include ':app'
include ':coding-push'
include ':push-dir:coding-push'
include ":push-xiaomi"
include ":push-dir:push-xiaomi"

I used repeat declarative in settings.gradle to solve. (Android Studio 3.0), I think it's AS's bug. Sometimes need restart AS.
