How to add module inside an Android module?

Question

Having the following structure.

-root

• app
• module1
• module2
  • libs
    • submodule

How to add module inside an Android module? This means that the module2 should still detect the submodule even without having specifying it in settings.gradle.

Currently implementation(project(":libs:submodule")) in build.gradle.kts of module2 is not working. It will work however if we do this

-root

• app
• module1
• module2 (still depends on submodule but located in root/project level)
• submodule

This is when we specified the submodule in settings.gradle

rootProject.name = "Sample App"
include(":app")
include(":module1")
include (":module2") // Has dependency to submodule
include (":submodule")

But what we want is for module2 to already include submodule so we don't need to specify in the project the submodule.

None of the modules are dependent on any other unless they are mentioned in build.gradle file of another module.

For creating module inside a module you can just move it to another module and update its directory graph in settings.gradle file appropriately.

So, I created two new modules test1, test2. I now created a new directory called tests. after this I moved my two modules from project directory to tests directory. I edit my settings.gradle file which had

include ':app'
include ':translations'
include ':test1'
include ':test2'

and updated it to following:

include ':app'
include ':translations'
include 'tests:test1'
include 'tests:test2'

then I created another directory inside tests directory called subtest and moved the test2 module there. then i updated my settings.gradle file to

include ':app'
include ':translations'
include 'tests:test1'
include 'tests:subtest:test2'

And I did it in the project configuration like in the following image:

and now it looks something like:
