Android工作室-看不到Java目录

Question

1. Created new project in Android Studio on the desktop.
2. in the Android view in the Project Explorer all looked normal.
3. Moved the project to a new folder on the desktop and opened it in Studio.
4. Now in the Android view in the project explorer there is no dropdown icon on the Java directory.
5. I have invalidated caches, cleaned the project and probably a couple of other things I have forgotten, still cannot see my source files.

I tried both copy and move using file explorer in win7.

Answer 1

I have faced the same issue, although @Igor answers fix your issue, it was different for me because the Java files are missing in the file directory. Same as you, I've also followed the same steps from https://developer.android.com/training/basics/firstapp/creating-project.html and there's nothing special with those steps.

I have resolved the issue by downloading the SDK quck fix in the "Messages Gradle Sync" explorer.

After that, the java folder will appear to the project explorer.

Answer 2

I've faced a similar issue: I could see my java directory in the Android view, but not in the Project view. I finally managed to fix it by going in the menu: File > Sync Project With Gradle Files.

Hope it helps someone.

Answer 3

Your top-level project in Android Studio should show the absolute path of the directory on your machine. Look in the Project perspective (not Android perspective). Like D:\workspace\myproject . Go ahead and navigate into that directory with file explorer on your machine, and make sure that its java sub-directory contains classes!

If you are using a library project, then you need to add below lines in gradle library level

android {
sourceSets {
    main.java.srcDirs += 'src/main/kotlin'
}

and you need to change the word kotlin to java according to folder name you already have.
