Adding java folders to android studio project

Question

Started working on my first project using Android Studio instead of Eclipse ADT . I would like to add sub folders to contain java.classes in order to structure my app but are unable to obtain references to them in my activity

structure is (with app name replaced)

src/main/[MyCompany]/[myAppName]/model/user.java

and

src/main/[MyCompany]/[myAppName]/helperClasses/SQLiteHelper.java

however I am unable to reference them either directly in code or by import, and are forced to put them in the appName folder with the activity to reference them.

Is this simply a limitation in Android or is there a way to organize your project with folders better. I used the new->folder-java folder option to create folders

Answer 1

IntelliJIdea mixes packages and directories.

So, right click on the java folder, click new - 'Package', then add your directory.

Answer 2

In my case I wanted a mock package with java folder:

1. First step you have to put project mode:

2. Click right button, new, Directory, in my case "mock".
3. Click right button, new, Folder, Java Folder:

4. Click in checkbock "change folder location" and put your path, in my case "src/mock/java":

5. The solution is this:

Answer 3

Try this path : src/main/java/[MyCompany]/[myAppName]/...
src/main/java/ is default source directory in Android Studio

OR

if you don't want to change your directory structure. you have to modify your build.gradle to change source directory.

something like: (this example is for ADT project)

android {

    ...

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

    ...

}
