Possible to create subfolders in drawable folder in Android Studio?

Question

Is it possible to create subfolder structures inside main res folders, especially in drawable folder using Gradle?

I have attempted this so far

sourceSets {

    main {
        res.srcDirs = [
                "/src/main/res/drawable-xhdpi/actionbar_items",
                "/src/main/res/drawable-xhdpi/intro",
                "/src/main/res/drawable-xhdpi/loading_screen",
                "/src/main/res/drawable-xhdpi",
                "/src/main/res",
        ]
    }
}

When I rebuild the project however I get this Gradle build error message something like this:

Error:(39, 23) No resource found that matches the given name (at 'icon' with value     '@drawable/app_icon').
Error:(40, 24) No resource found that matches the given name (at 'label' with value '@string/app_name').

This means to me that the gradle sees only the res folders specified by me in app.gradle file ? Therefore I added the rest of it to the app.gradle and same error occurs... Can anyone help please ....

I have looked at this question http://stackoverflow.com/questions/4930398/can-the-android-layout-folder-contain-subfolders and I followed the solution proposed in the second answer for that question, where someone manager to create subfolders for layout res folder — Adrian L, Sep 12 '14 at 09:36

No, Android expects all the files to be in a single directory, and does not allow subfolders to be used.

Most apps use a naming convention in place of subfolders, so in your example you might end up with a list of files:

intro_welcome.png
intro_background.png
loading_splashscreen.png
actionbar_delete.png
