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

Though include ':modules:mod1' , ':modules:mod2', ':modules:mod3' kind of gives you the solution, the AS annoyingly generates an empty module for modules. To address this gotcha, please refer to the settings.gradle on the gradle github repo. It basically includes every subproject as a top level one and then sets its project directory to be inside the subdirectory. This trick should perfectly address your need.

include 'mod1'
include 'mod2'
...
include 'modX'
rootProject.name = 'gradle'
rootProject.children.each {project ->
    String projectDirName = "modules/$project.name"
    project.projectDir = new File(settingsDir, projectDirName)
    assert project.projectDir.isDirectory()
    assert project.buildFile.isFile()
}
