I had app module running on my android studio project until I pressed delete by mistake. I am now unable to run my project as it doesn't detect app module.
I can see app folder in project view (containing build, libs, src folders) but I don't see it in android view or configuration setting where it says
I have an old apk file of the project.
I shared my project on github.
Please help me get my module back so that I can run my project.
All I had to do was File->Sync project with gradle files.
In order to not risk and further modify your content, try and clone again your android repo elsewhere and see if your module shows up there.
If it does, copy it back in your current repo.
I had this same issue, twice now. The first time, a full clean/rebuild did the trick. The second time, this didn't work. What did resolve the problem was opening the settings.gradle file and copying everything, then removing it to leave an empty file. Then save and resync Gradle. This failed, but then I pasted the old contents back into the file and did a resync again, which then fixed the issue.
Not sure what the problem was in the first place, but this worked for me so I figured I'd share.

I'm trying to remove "library" as a module. I'm using Android Studio 3.0.1.
If I click on the red "-" it removes it but after gradle builds automatically, it adds it back again. I removed the dependency from build.gradle, so it's not used by the "app" anymore. I can't "Delete" the folder from inside Android Studio either. The only thing I can think of is to remove it from Windodows directly, but I'm really curious if it's a bug or why I can't do this from Android Studio.
Any ideas?
As #CommonsWare won't answer the question, I will do it myself.
The solution for the problem is to remove the module name from settings.gradle and after that, deleting the module will work normally.
As #CommonsWare suggested, the solution is to open settings.gradle and delete the unwanted module name.
As #StayCool mentions, you can perform this solution and then restart the IDE (Android Studio) and the unwanted module(s) may reappear.
I got this to work by adding the following steps. It may be overkill, and some steps may do nothing, but here's what worked for me:
While IDE is open with the project:
Open settings.gradle and delete unwanted module names, save &
close file.
Delete .gradle folder and .idea folder. (do not
delete gradle folder--notice the period at start of file name).
In IDE go to File > Invalidate Caches/Restart (answer affirmative to
dialogs).
Your IDE should close and restart, then rebuild the folders you deleted, then the file tree should no longer show the unwanted modules.
If it doesn't work the first time, try the steps again. If it doesn't work a second time, I dunno...
I am new to AndroidStudio AND Gradle.
I imported a project from eclipse, created a module, and tried to run the project, but I got this error:
AndroidManifest.xml doesn't exist or has incorrect root tag
I have been looking at this previous solution for it:
How to build an android library with Android Studio and gradle?
But that solution is WAY too advanced for me.
Could someone please help me understand in simpler terms what is going wrong and how I can fix it?
Thank you!
Update after one of the answers:
These are the options I have under the build menu:
clicking on Sync project with Gradle files button will solve your problem.
That button is under File section on Android Studio 3.6.1
Close your Android Studio
Goto C:\Users\user\.AndroidStudioX.X\system and DELETE the cache
folder
Launch the Android Studio
Goto Build (menu) -> Clean Project when done click the
Build (menu) again and click rebuild project.
That should solve the problem.
For me the issue went away once I opened the android folder of the project in Android Studio to run the project.
So basically, because I was trying to run the Android project from the Root folder, it gave me the error. We need to run the project by selecting the android folder of the project only.
Hope this helps someone!
Click on File > Invalidate Cache/Restart, and that's it. Your project should start working.
For me clicking on Sync project with Gradle files button did not solve the problem alone.
After Syncing project with Gradle files, I explicitly had to invalidate the cache and restart studio. Only after this action, the red cross-mark over configuration disappeared and everything started working.
In my case, my android project got corrupted and some of the files were showing characters, binary numbers, etc. I tried the following solutions
Invalidate & Restart
Rebuild Project
Sync with Gradle File
But none of the above solutions worked for me.
Then I just deleted the cache folder under C:\Users\username\.AndroidStudio3.6\system
and all the invalid characters disappeared and the actual contents of all the files were displayed. This solution worked for me.
Every Android project needs a file called AndroidManifest.xml to tell Android about itself. Either your project doesn't have one, or it's not in the place that Android Studio expects it to be. Try to find it, and move it to the root folder of the project.
1.Check whether the manifest file is there or not.
2.If it is there, check whether the package name is correct or not..
3.If you project has small number of classes, then you create new project in android and then copy paste your code from eclipse. It will be simple. But it is recommended only for small project.
And finally click 'Sync' in the Gradle file. Followed by Rebuilding the project will do a trick.
In my case the Manifest file seemed to be corrupted or maybe its meta data. Trying to open it in Android Studio will show some characters that you see when opening a binary file with a text editor, for ex. Anyway, my project is under Git, so I just deleted it and restored it back, problem fixed.
Go to C drive click User then select your android studio folder then select System find Cache folder and delete this folder before doing this close your android Studio.It will surely work.
I also had this problem, things I tried:
I delete user->gradle-> delete cache folder
Android studio-> file-> Invalid cache/restart
Using my problem is get resolved
I also had this problem, things I tried:
Syncing the file with gradle
Invalidate/Restart
But the problem was still there in the manifest folder-> manifest.xml file it had only 1 line.
So I went to User-> your_username -> Android Studio v -> caches and Deleted the cache folder.
Started Android Studio, and my problem was gone.
But I am not sure which of these might solve yours.
I have opened AndroidManifest.xml in file editor. Add some letters, save it, then android studio found AndroidManifest.
After this I can build project successfully
if your AndroidManifest.xml looks wierd than you can try checking local history or git history. by doing that you can copy paste the previous version AndroidManifest.xml
Experienced that too, there is a line on your manifest code that's incorrect, simply go through it and make necessary corrections.
I had created a project with Android Studio and pushed it to bitbucket. After few weeks now I have cloned it on different machine to resume my work. I imported the project in Android Studio and now I keep getting this error.
Migrate Project to Gradle?
This project does not use the Gradle build system. We recommend that you migrate to using the Gradle build system.
More Information about migrating to Gradle.
Don't show this message again.
I have the gradle directory in my project. I tried using the option of use local gradle distribution and pointed it to downloaded gradle-1.10 but I still keep getting the same error.
First of all I would remove following files/directories from your project-folder:
bin/
build/
.idea/
.gradle/
projectname.iml
Then try to import the project again in AndroidStudio. This usually works for me, and to avoid that in the future, adjust the .gitignore file properly.
If the first tip does not help: have you tried downloading a more recent gradle (1.12) locally and point to that directory? (Don't point AndroidStudio to download, but do it yourself first).
You are not using a gradle-wrapper are you?
If you haven't started coding in your new machine, the simplest way would be to just delete your project directory, and use "import from VCS".
Not worth the time to find the "solution", trust me. I tried. Almost 2 years since you asked the question, and people are still getting the issue, then this problem is obviously not worth solving.
Most probably you have git checkout a parent directory of a working android project.
Close freshly checked git project
Open Project
Navigate to the git checkout directory
Select a sub directory inside the git checkout project and that is the intended android project for you
I ran into the same problem. For me the problem was my sttings.gradle was cleared. After adding incude: 'modulename'. It worked for me
I fixed this issue with the following steps:
Make sure that the following two files are in your project directory. If not, create a new one with reference of your other Android projects. These are default auto-generated files.
settings.gradle
build.gradle
If it is still showing any errors when you open your project, restart your project by selecting file/(invalidate /restart).
I had the same problem and I managed to fix it by invalidating caching and restart File - > Invalidate caches and restart
I just did an update of Android Studio and the project I was working currently on was completely erased. I think it prompt me on "terminating the main process" and I accidentally clicked ok. Is there a way to recover my project somehow? Why would the files be erased by simply updating?
In my case i didnt lose the whole project just the main folder which contains the java and the ressource file
I right click the project --> local history --> show history
--> revert selection
If you dont have the project you can create one with the same name same file names then do exactly the same thing as mentioned
Its a lesson to use github :v
I've had the same situation. I haven't been able to replicate the behaviour. My hope is the details bellow will contribute to some answer.
I was working on a project that required the addition of some JAR dependancies. The JAR dependancies, were added to the lib file and I was editing the project build.gradle script to compile them.
I was adding a dependency for jackson JSON to the build.gradle file when the issue occurred.
While typing 'compile com' android studio locked up for a moment. All the files in the project manger disappeared. Android Studio ran thru a gradle build.
Initially I though I'd inadvertently opened an new empty project. Unfortunately my files were gone.
Android Studio Never Closed or Crashed
The Folder which contained all the project files was completely empty. As if a batch deletion had occurred.
'File -> Open Recent' showed no evidence that the given project had been opened.
I had been working on this file during the previous 24 hours, opening it thru the 'File -> Open Recent' that morning to pick up where I left off the previous day.
It was Disconcerting.
I got the answer from the same problem here.
The project is not erased,just moved to another place, I also don't know why.
I just search my project's name in all my disk, then find the project under another folder.
I use the Mac OS, so the new folder is-
/Users/jokerlee/Applications/AndroidStudioProjects
I am having the Same problem even now on Android Studio 3.1.4.
The entire project folder is wiped out.
But what I do currently is immediately save the entire project folder somewhere, like Company Folder, then Copy and paste again. Hectic though.
Done this ten times now. I will test not using default project location like /users/........
I face same problem too. I solved the problem by doing following steps.
In Android Studio, open the project main directory.
File -> Open -> Folder path where your missing project existed.
Lets say if your missing project is under ../AndroidStudioPrj/MyApp, please open AndroidStudioPrj directory.
Then VCS -> Local History -> Show History
In history, you can revert to get back your code.

I got this error on Android Studio (AS):
How I got it:
I created an AS Project from scratch and everything was fine.
Then a popup showed up, and (if I recall correctly) was saying something like: "Android Framework detected". I pressed "Yes' and some changes happened to the project/module. And after that I got the above error
Edit:
In my case the problem was not Gradle related. It had to do with IntelliJ/Android Studio configuration, an .iml file in particular.
I realized that after reading this informative post here.
On Android Studio v0.8.2 clicking on Sync project with Gradle files button solved my problem.
update
Thanks to the comment of jaumard. If the Sync project with Gradle files it's not visible you have to open the Gradle panel and click sync icon on top the toolbar.
Just call (in any case) File -> Invalidate Caches and Restart....
In my case:
settings.gradle file was empty. I added defualt code:
include ':app'
Then I clicked
Then project start works.
Double check that under project structure / module / Manifest file it points to the correct manifest file in your code and not the one in generated sources.
This is true for both Android Studio and Intelli J. Sometime when you import project from existing sources it prefer the manifest file inside the generates sources directory.
What helped for me was:
delete .gradle/ folder
delete .idea/ folder
delete ****.idea*** file
reopen Android Studio
import from gradle as Android Studio then suggests
I ran into a similar problem. Looks like my .../src directory for whatever reason moved under my .../lib directory. I moved it out of the /lib directory. Now both /lib and /src are at the same level. After a couple of clean rebuilds and restarts of Android studio everything is back to normal. My emulator started up fine.
You might want to check your directory structure. Compare the directory structure with a working project. You might be able to see the difference.
Moving my AndroidManifest.xml to PROJECT_NAME/src/main fixed the issue.
I had the same errormessage and noticed I had 2 MYPROJECTNAME.iml files, but with a different casing of MYPROJECTNAME. I created this situation after checking out from SVN the project into a directory with the casing error.
Just throw away the IML file with the wrong casing, after saving the content of both and use the content that works
I had this problem with a multi-module project when I renamed the app module. In my case to solve the problem I had to manually update the app module name in the project's settings.gradle file (Android Studio didn't update that value)
Happened to me. Found that i had wrongly opened the parent folder of the actual project in Android Studio.
In my case, it was my AndroidManifest.xml file, it was all messed up due to a new library that I added in my build.gradle.
So I took the AndroidManifest.xml from my latest commit on Git and I replaced it the current one, and also my settings.gradle was empty so I added include ':app'.
Hope it helps, and happy coding !
Facing same issue, resolve after adding the missing build.gradle file in root project.
