where are these files located?

michael_vons Over a year ago

.diea and .iml may be hidden. On macOS use command+Shift+period to show hidden files.

Otziii Over a year ago

Located inside the project folder

Sergio Serra Over a year ago

If you want to recursively delete .iml files use find . -name "*.iml" -type f -delete on the root folder. Use it without -delete flag to dry run first.

First of all you should update your Android Studio as stated here: https://code.google.com/p/android/issues/detail?id=77983

Then you should go to File -> Invalidate Caches / Restart -> Invalidate Caches & Restart.

Then try to build the application again.

And...you have to be patient. It make take a while for everything to figure out the changes. I saw the error pop up a 2nd time before the rebuild was complete. But once complete it started working.

Martin Over a year ago

Got a file not found on the outdated library which gave me the error mentioned above. So Android Studio has a problem forgetting outdated stuff. Have to remember that.

Just encountered the issue myself and this remedy worked perfectly. The fix appears to remain relevant to this day (July 2023). I'm running Android Studio Hedgehog | 2023.1.1 Canary 14.

Goto .idea/modules.xml & delete the invalid/not existing path <module />. Then File => Invalidate Caches / Restart.

You can delete whole modules.xml file and invalidate. It works.

Ashiq Over a year ago

Only this worked for me and restart and sync there was no .idea/modules.xml file. Instead there was a .idea/modules/app folder created with two .iml files.

Invalidate Caches and Restart did not work for me. I also updated all my Android Studio files with no success.

The solution I found was importing the android folder by clicking "Import project (Eclipse ADT, Gradle, etc.)" rather than clicking "Open an existing Android Studio Project" or dragging the folder onto the app icon.

Apparently the problem is caused because a module in the project has an *.iml file that does not contain external.system.id="GRADLE".

When you import the project (as opposed to opening it), the iml files are completely re-written, thus removing the error.

I found the info here: https://issuetracker.google.com/issues/37008041

Using Android Studio 3.0.1, I had a new project with local library module dependencies. I directly edited the settings.gradle file to add another library, and that's when I started getting this error. Invalidate Caches & Restart didn't do the trick, but Import did. Could be that the .iml file didn't "catch up" to the Gradle settings file changes.

This works, but one warning -- it will delete your Shelved Changes in Version Control

This worked best for me. Thanks. Do note that your project directory name should not contain any whitespace at all to avoid any future issues.

I know it's an old question. but I faced this problem after updating to Android Studio 3.0. I solved it by deleting app.iml file inside my app module and then Invalidate Caches / Restart.

In my case I had to delete all the .iml files from all the project sub-directories and delete the .idea folder from the project root directory. Then open the Android Studio again. It will recreate those files.

Delete .idea/modules.xml
Reload All Gradle Projects

You do not want to remove entire .idea directory, because it contains e.g. dictionaries and shelved changes.

In my case settings.gradle contained invalid configuration.

I changed:

include ':app'
rootProject.name='<somthing else>'

To:

include ':app'

Error is gone. So maybe check your settings.gradle for potential errors. If this won't work try to remove cache and other tips.

If the above doesn't help you - check your module .iml file and see if it contains any errors. (for the app module it will be app.iml).

Also check the .iml file inside your .idea folder. Mine didn't have any errors, but an old module was being referenced there, this was causing the issue

You may resolve by below process:

In Android Studio, go to left panel, switch from Android to Project pane
Expand .idea folder, you can see modules.xml and open the file.
In the modules.xml file, you might see like below:

  <component name="...">
    <modules>
      <module fileurl="file://$PROJECT_DIR$/[check...].iml" filepath="$PROJECT_DIR$/[check...].iml" group="myProject" />
      <module fileurl="file://$PROJECT_DIR$/app/[check...]-app.iml" filepath="$PROJECT_DIR$/app/[check...]-app.iml" group="[check...]/app" />

Check that match the module name correctly in module element
And then, sync the gradle file

Close the Android Studio and Move ".idea" Folder and paste it outside Project root folder( For Back up if you need).

Open the Android studio. On Opening the project it"ll ask add module (app) to your project. You can ignore the same.

It set set default build variant to be "debug". You can see build variant tab on left corner or hover on "Monitor" Symbol on left bottom

Note: No need to change your .iml file of your project.tom to get build variant option and "Invalidate Cache and Restart" will also not work rather it will clear your history files too!.

In My Case

I have deleted

android -> .idea Folder android -> appname.iml file android -> app -> app.iml file

Open project in Android Studio and no need to File -> Invalidate Caches/Restart

You can do Invalidate Caches / Restart for your case.

The above solution I've tried but didn't work for me.

I deleted the .idea folder from project directory.
Invalidate caches using Android Studio menu File -> Invalidate Caches / Restart
Deleted .gradle folder from user profile directory of Windows 10 operating system. (i.e., C:\Users\YourUserName\.gradle)

Try this solution if the above not working.

You should import the the project

https://issuetracker.google.com/issues/37008041

This error shows up when there is a module in your project whose .iml file does not contain: external.system.id="GRADLE" Can you please check your .iml files? Also, instead of opening the project, import it, that will completely rewrite your .iml files and you won't see that error again.

Try:

Go to File->Invalidate Caches / Restart.
Close android studio, Go to C:\Users\(Your UserName)\.AndroidStudio(version)\system and delete caches folder.

If till now nothing worked, then this step will definitely work...

Simply change project location and import project with new location.

For windows users, this can also be caused by filesystem corruption.

If all steps above do not correct the error:

Close Android Studio
Open Command Prompt as Administrator
Run a chkdsk /f on the drive your app is stored
Delete .idea folder
Restart Android Studio

I had the exact same error and it was so annoying to see the alert every time I stared Android Studio. I tried the solution mentioned above including invalidating cache, restart etc, nothing made it go away.

In my case, we had a module that was deleted from source and the reference also removed from settings.gradle. Turns out, .idea/modules.xml was still referencing that module.

All I needed to do was remove that line from <modules> in .idea/modules.xml and it made it all go away.

In my case it is because the root project name have a space. So instead of naming it as sample project, it should be sample-project or sample_project.

I have the same issue. I was tried Invalidate Cache / Restart & also sync project with Gradle Files but still didn't work. But worked by use the following steps:

upgrading gradle distribution version at gradle.wrapper.properties.

distributionUrl=https\://services.gradle.org/distributions/gradle-6.5-all.zip

And also Android Gradle Plugin at build.gradle project

 classpath 'com.android.tools.build:gradle:4.1.2' //upgrade gradle plugin here

Then Invalidate Cache / Restart
That's all solved my problem. Hope you too

I have encountered this problem.

I'm using buildSrc in my project.

I think the problem is with buildSrc. To solve the problem;

1- Kotlin and Android Stuido version updated (Kotlin version is 1.3.21, Android Studio version is 3.4)

2- Clean cache and restart android studio

But the problem is not solved.

As a last resort, I deleted the project file and clone it over git and the problem is solved
