"AndroidManifest.xml doesn't exist or has incorrect root tag" Error

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.

AndroidManifest.xml file not found

I'm using git, and creating lots of git branches for new features on a project I'm working on. Every once in a while, I'll create a new branch off master as usual (let's call this broken-branch, and this error appears:
Android Source Generator: [demo] AndroidManifest.xml file not found
I'll create a new branch off master, cherrypick the changes on broken-branch onto this one, and everything works fine. Why do I get this error, and how can I avoid it?

This happened to me today.. I clicked "Sync Project with Gradle Files" and all went fine.

While my IDE is IDEA13 with maven. Work fine with maven in command line, while using IDEA run( shift + F10) show this error. I do as below and fix this:
1.Open .iml in the project root.
2.Find some line like:
<option name="USE_CUSTOM_COMPILER_MANIFEST" value="true" />
3.Remove this line or change value to false.
This is my work way.
May Help.

I use IntelliJ Idea and found next solution:
in the root of the project (in catalog with root build.gradle) create file settings.gradle which consist include ':app'
Than go to IDE and run Gradle - refresh.

I know the problem in IDEA because you create a new project with Java configuration (not android, but with android sdk dependency)
File > New Project > Java (Java Module) > Project SDK Android 4.X
Here is the solution :
File > New Project > Android (Application Module)

If you are using Maven, backup the project and close it. Open IntelliJ and select Open..., choose the pom.xml file and then select yes to open this project. Because there is already a project a popup should appear, choose 'Delete Existing Project and Import'.
Note: I'm using IntelliJ Community Edition version 13

When I get "AndroidManifest.xml file not found" error I clean and then refresh the project and these steps seem to fix the problem.

It happens to me when I don't have .iml file to open the project. It's very easy to fix, you just need to close the project and reopen it taking care of select build.gradle file before click open.
I hope it helps somebody.

This worked for me.
My project already had a settings.gradle file.
I simple had to add the line include ':app' . N ow i can build and do everything.

open IDE
project
|--->build automatically
uncheck it
clean the project
check build automatically opriot

I just had this problem while trying to build the swagger code gen project. For whatever reason IntelliJ thought I should have an Android facet. Removing this facet allowed the entire project to build.

If in case, you encounter an error which shows:
AndroidManifest.xml file is not found
All that you have to do is reinstall the flutter package and the error is resolved!!!

Go File,Project Structure or press Ctrl+Shift+Alt+S,
Go Facets, Select your android project, in the structure there are configuration files, folders. Image of structure tab (before)
Location of AndroidManifest file was like this:
D:\Programming\Dart Flutter Projects\tip_calculator\AndroidManifest.xml
Change the location like this.
Image of structure tab (after)
Changed it to here:
D:\Programming\Dart Flutter Projects\tip_calculator\android\app\src\profile\AndroidManifest.xml

flutter upgrade --force
Helped me.
Works for you?

Eclipse error : Your project contains error(s),please fix them

I am using Eclipse Classic 3.7.2 working only on Android. I use Ubuntu as my OS. When I run any basic Android application on Eclipse say "Hello World", it results an error called Your Project contains error(s), please fix them before running your application.
Now I have googled and checked here and may others but I did not get the solution.
I also tried Project > clean... but it isn't working.
Windows->Show Views->Problems shows 2 errors:
Error generating final archive: java.io.FileNotFoundException:/home/android/Desktop/helloworld/bin/resources.ap_does not exist.
Unable to parse aapt...

It may be be because of Eclipse's debug certificate expiration.
Please look at to my this answer.

Close and restart Eclipse. It works everytime !
Its bug with deleting android projects I think.

I have faced exactly same type of issue. Just update your eclipse ADT plugin to latest version.
After update clean build the project.

Go to your .android folder and delete your debug certificate. In my computer it is in this path
E:\Users\(ur profyle)\.android
Inside that there is a file name 'debug.keystore'. Delete that,clean and try to build the project again. Sometimes this error is caused when the certificate expires.

You need to update your Eclipse to the latest available version(Indigo) and then need to update the ADT(level 16 I think), as the latest ADT updates works on Indigo only. After the updates close and reopen the Eclipse, it should work now.

Go to Project Properties -> Java Build Path
Select Libraries and remove Android Dependencies
After this my problem solved.
The error was because of updating

Set your Android sdk path once again and restart Eclipse. It fixes the issue (window-preferences-android-sdklocation).
Or, just update your Android tools and restart Eclipse works.

Check your libs folder ..
some libraries cause this ,
it happened to me once and i was use Apache POI .. i tried to delete the jars from libs folder and it's worked ..

I had this problem in Eclipse after executing Project => Clean... That option deletes all the compiled stuff from your project and, therefore, the java classes start looking like if they all have errros.
To fix that problem I had to:
1. open my java clases and XML layout files(for android dev)
2. do a small change, something like a adding a space
3. Hitting Crt+S to ask eclipse to save and compile the class once again.
This solution may or may not work for you. I recommend looking at your specific problems using the Problems tab of Eclipse (Found at Windows=>Show View=>Problems) since it tells you about the exact errors and other very useful information.

If you're using android support library make sure you have not added jar files ( android-support-v4.jar and android-support-v7-appcompat.jar ) in your libs folder.
you only need to add android-support-v7-appcompat as library on your project.
It worked for me the time I had the same issue

My project had no errors in it but I noticed another open (unrelated) project which did have errors. I closed that project and my other project worked fine again.
Now the "unrelated" project used to be related but I'd removed the dependency ages ago. Closing it solved my problem so I have to assume there is some Eclipse bug in there somewhere which is still linking to it in some way. I'd say if I created a new project and copied everything in it might have achieved the same result.
As a test for yourself.. maybe close all other projects except the one you are working on.

When i create new project in android?

When i create new project in android, i found each and every time error sign on project name just like picture, that could not run? So is that any solution to remove this error?
default.properties file seems like this, which is message from error log.

Have you tried going to Project->Clean... in the menu? This sometimes will help. Also try unchecking Project->Build Automatically and then right click on your project and run as Android.
Edit: You may also have to delete your debug.keystore file. This file should be located in your home directory. Then try clean and build from eclipse and the file should then get recreated.

I used to have a similar proble. Restarting eclipse might resolve it.

Give this a try to fix your properties.
Right-click the project -> Android Tools -> Fix project properties

All my android projects have r.java related errors

For some reason my eclipse/android development environment has stopped creating the r.java files and wont read them in any of my projects. Should I just uninstall eclipse and all traces of it and the android sdk Ive been using and start fresh?
Ive been looking for the past couple hours for a fix but I cant find one at all that seems to work so any suggestions on the matter would help.

Every time I update my source I always do this:
Refresh project
Clean project
Refresh project
Works every time (unless I have a build path issue, then Right Clicking and Doing Android Tools->Fix project properties usually works)
Having build errors can keep the R file from being generated, make sure you don't have any syntax errors.

Try touching (making non-changing edit) one of your .java files and seeing if it forces the R files to rebuild. This appears to be a bug with Android SDK / Eclipse integration.

This happens to me a lot. Two things to try.
1) Try to clean the project
If that doesn't work. This usually works for me.
1) In eclipse delete the project (BE SURE NOT TO DELETE THE SOURCE)
2) Close eclipse
3) Open eclipse
4) Add the project back via New Project from existing source

You can try this:
Make sure that "Build automatically" option is on (under Projects menu)
Clean your project
Refresh your project

I fixed this by removing parentheses from a string title that I had created.
I am a complete n00b so I did not think that adding () to a title would cause problems.
