Can we have project without app folder in android studio with everything (java/res/etc) in root

Question

I would like to know that is it possible to have android project without Application module (app or any other name) in Android studio?

Means i can create package and res

Answer 1

app/
build.gradle
src
jni
AndroidManefest.xml
build.gradle
settings.gradle

It's doable and here is how I did it:
1) Import the eclipse project from Android Studio.
*if you have a android studio project already, skip this step.
2) Open build.gradle under sub dir app/ and copy the contents and append/paste it to build.gradle of the top level.
3) Move all files under app/ to top level.
*if you don't have these files in top level yet.
4) Remove settings.gradle.
* you don't need it any more since you don't have app as a submodules.
5) Added the following lines to build.gradle

sourceSets {
    main {
        manifest.srcFile 'AndroidManifest.xml'
        java.srcDirs = ['src']
        resources.srcDirs = ['src']
        aidl.srcDirs = ['src']
        renderscript.srcDirs = ['src']
        res.srcDirs = ['res']
        assets.srcDirs = ['assets']
    }

• Change the dir name to match your layout.
  6) "Clean Projet" and "Rebuild Project"

Note: If you have other submodules in additional to "app", you will need keep settings.gradle and remove:
include ":app"
from it and keep other submodules.

See my project layout here:

The final build gradle is a combination of two together:

Hope it helps.
