Project already contains module with this name -- Android Studio

Question

I had successfully imported a Module in my Application project in Android Studio. Then I deleted or removed the module by following the below link:

How to delete a module in Android Studio

I also removed the project module from the dependencies of my build.gradle(app) file.

Now, When I need to again include the same module project in my Andorid Application, it doesn't allows me, and gives the Project already contains module with the same name error.

I had check in my Project, Package, Android Structure but the project module which i need to Import and add as a Module Project is not there but still it say it already exist.

Can anyone help me to overcome this issue.??

Were you ever able to solve this? im running into the same problem. Accidentally deleted a dependency project and now i can't add it again because it said there already is a module with the same name. Tried all of Chirag SolankI's steps, but it doesn't work... – Boston

Answer 1

If somebody faces this issue, except removing the Folder containing the old module also remove from the settings.gradle file the line corresponding to the old module: include ':youroldmodule'. If you dont remove that line manually, 2 modules with the same name will appear when trying to add module dependency.

It turns out that I just need to add the module name into settings.gladle file, sync it and it will automatically appears inside Android project. I didn't even need to use "File / Import Module" dialog at all! – Repletion

Answer 2

Switch to the Project View. Then open .idea/modules.xml. Find and delete the line that corresponds to the module. Then Invalidate Caches and Restart. That's it.

I solved the problem through this way:

1. Open Module Settings(Mac: command + down; Windows: F4) and delete the module.
2. Delete the module folder on the disk. You will find it at ~/AndroidStdioProjects/YourApplicationName/ModuleName.
3. Import the Module.

Answer 4

I have encountered this. And I deleted the folder which below my project with the module name I set before, then I can import a module with same name again.

Hope this helps you.

Answer 5

The project view on the left hand side, doesn't show 'everything' your project contains. You can switch the view from the drop-down menu, which is defaulted to 'Android' and change it to 'Project Files', which will probably show you where the problematic reference to the Module remains.

Alternatively, just check on disk where your project is located. I found references in the main project folder.

Answer 6

You can't import a module if you've put the code for the module in the place it will end up being copied to. I had the module source code placed in the project root folder and it failed to import with the above message. If you move the code away somewhere, on import Android Studio will copy the code in.

Thanks for sharing this, i had this same problem and as you said, AndroidStudio wants to copy the code over the project folder, so moving it to another folder and then letting AS copy the code was the solution. – Coppersmith

Answer 7

If you still see the error after removing the code from settings.gradle and the app gradle file, check the following file and remove any entries with the module name you are trying to remove.

./.idea/modules.xml

<project version="4">
  <component name="ProjectModuleManager">
    <modules>
      <module fileurl="file://$PROJECT_DIR$/app/app.iml" filepath="$PROJECT_DIR$/app/app.iml" />
    </modules>
  </component>
</project>

Remove compile project(':module_name') from build.gradle under app folder

Answer 9

This worked for me:

In app/build.gradle, remove this line from dependencies {:

implementation project(':library')

In settings.gradle, change

include ':app', ':library'

to

include ':app'

Then you can import the library. Be sure to put the lines back into the gradle files you took out above.

Those who are still seeing this issue and have already removed the module from settings.gradle file but still sees that Module already present while importing it again, This is what I did: 1.) Switch to Project mode in Android studio for your project 2.) Once switching it to Android mode, delete that module manually by clicking right click on it. And Hope it works for you now.

Thanks for the answer, but nothing happens, If I change the name it takes, but I don't want to change the name of the Module due to some reasons. – Aldershot

you are not able to remove in Dependencies.??# – Leukocyte

I had removed from dependencies, but it still says the Project already contains the module with the same name, although I had removed it. – Aldershot

Answer 13

I solved this by removing the existing module from the project structure, then renaming the folder. It finally worked when I removed the folder, ran a sync, then re-added the folder and attempted to import.

Answer 14

In one condition if you have copy a folder like this

rootProject/module1

if you import module android studio will find if you have same name folder. if you have it is not import android studio will tell you you have contains this module ,you just add this in setting.gradle like

include ':modlue1'

If shows this error after deleting the module from project structure then, select Project view of our project in android studio and then explore and the there will be the folder of module that we imported, right click on that and Delete it and rebuild the app.

Answer 16

If any of the above answers worked for you and you are sure that your branch is clean then close your Android Studio, browse to the root of your project and delete .idea folder. Then re-launch Android studio and run your project.

Answer 17

I had same issue, initially created a module, then removed it from settings.gradle and finally the fix was to ACTUALLY remove ALL folders related to that module, those won't be visible in the ANDROID view, hence change to project view and remove all related or browse using an external tool and remove all folders

Answer 18

For me, there was still a reference to the old module in my project's /.idea/gradle.xml file:

<option value="$PROJECT_DIR$/mymodule" />

I just deleted that line then re-synced with gradle and the error went away.

Answer 19

In some cases invalidate cache and restart android studio will also work. Because when fetching your code from git it might have some issue in my case it worked for me.

Answer 20

i had the problem in android studio, that i created some submodule, but wanted to delete it again, then on "Create New Module"->"Java or Kotlin Library" when entering the Library Name, it said "module_x_y already exists.". I followed the solutions above, but did not resolve the issue completely. Then i searched for "module_x_y" in the whole project (via Notepad++ full text search) and found in \.idea\workspace.xml the line

<change afterPath="$PROJECT_DIR$/module_x_y/README.md" afterDir="false" />

i deleted this line and my android studio did some strange behaviors, but after some short wait period, i was able to create the module with the name again. So i guess you have to remove the module from all the build.gradle files etc. as mentioned in the solutions above and in case you still cant re-create the module, take a look at workspace.xml, maybe this helps someone.
