my project was working well but suddenly when I ran it on my phone, Android Studio freezes and I should stop it from task manager.
before this happens I installed "Geny motion" & "Virtual Box", but when the error occurred I uninstalled them. but the problem insisted.
Solutions I've tried
I uninstalled it and installed it again
I unplugged and plugged in my device
I disabled android indexing from setting
None of the above solutions worked.
I had today this exact problem. None of the above helped me until I found simple solution here
Just run File -> Invalidate Cache and Restart
That simple and it works!!!
Delete all Android Studio data - .gradle .android .androidstudio folders from your home folder. And all project build folders gradle and iml files.
This worked for me.
1.Close the project
2.Remove the project
3.Close Android Studio
4.Open it again
5.Open the project
Enjoy Coding!
I checked my java file and I saw somehow all the code in one of my java files was replaced with "NULL NULL NULL NULL....."
I deleted the file and the application runs without a problem.
Android Studio (3.1.3) froze on me while editing a source file. I waited and finally killed the process in Task Manager (Windows). Twice I tried to start up again and both times it got stuck with the "indexing..." message in the lower right. Both times I ended the process in Task Manager.
I looked in the source folder of the project I was working on. The source file I had been editing when it froze was "Receipt.java". There was another file in the src folder "Receipt.java__jb_tmp__". I deleted that file and Android Studio started up fine. It looks like I lost some edits, though.
When I did start up, it detected there had been some error and offered to submit a report.
If the project is large & has a lot of modules, you might need to increase the Allocated Heap Size for Android Studio.
Go to Edit Custom VM Options from Help menu and increase the value for -Xms and -Xmx
This is what I'm using
-Xms2048m
-Xmx8192m
-XX:MaxPermSize=2048m
-XX:ReservedCodeCacheSize=1024m
-XX:+UseCompressedOops
In my case color was declared as invalid, Android Studio ignored that and during building it froze. I had to remove the file, let it index, paste it back and fix the color string (it gave me error when I entered the pasted file)
just rename project folder then open IDE, it will show
now rename back to origin folder name, click open project
it work on my case
I have older project with sdk version 22, when I open it in android studio 3.1.2 on macOS. It keep indexing forever, everything was installed and configured properly but indexing loop never stopped.
Following worked for me
File > Invalidate caches/restart… > Invalidate caches/restart
Go to the File menu and click the option Invalidate Caches / Restart This will solve the problem ! Enjoy ;)

I have an odd problem with Android Studio.
Here is how my class file looks like on Android Studio
And here is what it looks like on a text editor.
Any ideas why it is happening? I have tried closing then reimporting the project, invalidate caches and restart, clean project, build project, delete .idea folder and .iml files. All of my files are broken when opening in AS but looks fine on text editors.
UPDATE: Quicker solution by the user Hong given below:
Delete the caches folder: C:\Users\my_user_name\.AndroidStudio3.3\system\caches
=====================
Here's what worked for me.
Close Android Studio
Go to C:\Users*your username*
Locate the Android Studio settings directory named .AndroidStudioX.X (X.X being the version)
Rename it to something like old.AndroidStudioX.X
Start Android Studio, and when it asks if you want to import settings, choose the old directory
This should fix the issue.
Thanks to the Answer of Asim, I found deleting folder caches fixed the problem for my case (all gradle files in Android Studio show contents that have nothing to do with the actual contents of these files):
C:\Users\my_user_name\.AndroidStudio3.3\system\caches
Edit[2020-07-17]:
This is still happening with Android Studio 4.0, so I have to delete the following folder to fix this problem:
C:\Users\my_user_name\.AndroidStudio4.0\system\caches

This solution no longer works for Android Studio Arctic Fox. Please see the new answer by Nikunj Paradva. I have used the new solution and it works.
Solution for Android studio Arctic Fox and Higher Versions
Steps
Exit Android Studio
Delete caches folder from
C:\Users\{username}\AppData\Local\Google\AndroidStudio2020.3 // For Arctic Fox
Open Android Studio and your code has being Perfect
Check your Android studio version and Target that version folder at below location
C:\Users\{username}\AppData\Local\Google
Note : AppData folder is Hidden in Windows
Does this situation warrant a bug report?
Yes! In fact this problem has been reported to the Android Studio team, and anyone willing to help us investigate is welcome to contribute there. Thanks!
You can also try the workaround in Hong's answer.
Close Android studio and then delete the caches folder: C:\Users\user_name\.AndroidStudio3.4\system\caches
Try to delete the Android Studio IDE cache data listed below per your platform:
Windows:
%USER%\.AndroidStudio[Preview]_X.Y_
Mac:
~/Library/Preferences/AndroidStudio[Preview]_X.Y_
~/Library/Caches/AndroidStudio[Preview]_X.Y_

Updated my android studio days ago and was faced with the same problem. Solved it by uninstalling android studio and reinstalling the previous version set up I had left the SDK intact so I didn't have to re-download them working perfectly guess I won't be updating again soon.
Thanks to #Henry for confirming, by several similarly observed whacko problems the past two days, that my problem is indeed caused by a bug in AS. Follow his links to become convinced yourself. I'll let Henry file the bug report.
So there's no fixing my problem in situ without great effort--wait for bug fix.... which could take awhile.
So here's what I did to work around it and get back to work (it took less than 10 minutes):
create new project with no activity
(Do the rest inside the IDE, not using Windows or DOS.)
copy all .java files into the java folder in the IDE (it's ...\app\src\main\java\)
copy all res folders into the res folder (...\app\src\main\res\)
copy all asset files into main folder (...\app\src\main\assets\)
copy androidmanifest.xml into main folder (...\app\src\main)
do a global replace of old project name to new project name
I didn't change any of the files in the new project's ...\app\ folder because compilation was normal.
(I'll tell you this: when I saw what I THOUGHT were mangled FILES and looked at the History and saw nothing resembling what should have been there, I got a sick feeling, but I immediately opened Windows Explorer, selected all of the project's java files, and opened them, en masse, with Notepad++. Whew. No problems seen. (I didn't really think AS could actually mangle the files and I doubt it ever could. But it did wake me up at 5am!))
copy your android project to another location then open it from android studio
I changed my projects location and it solved my problem. This happened when my system was accidently shut down due to power failure.

I changed my projects location and it solved my problem. This happened when my system was accidently shut down due to power failure.
My laptop crashed while Android Studio was running.
Now, When I tried to open project in Android Studio it gives me weird error and no project is opening.
Cannot load project: java.lang.RuntimeException: java.io.IOException: java.lang.AssertionError: Unexpected content storage modification"**
Edit: Also I'm in the welcome screen of Android Studio and have no access to Menu options to Invalidate Caches and restart Android Studio.
I had really big issue as I was not able to open project in Android Studio. Every time I start Android Studio dialog box appear that says:
Cannot load project: java.lang.RuntimeException: java.io.IOException: java.lang.AssertionError: Unexpected content storage modification
I solved it by doing following steps:
Close Android Studio
Go to the directory home_dir/.AndroidStudio/system/cache
Remove all the files in the cache directory.
Then restart IntelliJ
No guarantee this will work, but I have previously fixed a problem which is similar to this by invalidating the cache.
In Android Studio this is under File -> Invalidate Caches / Restart
For Android Studio 2.O follow these steps:
Close Android studio
Go to ~/.android/cache
Delete content
Restart android studio
Hope this will help
In C\users\.Androidstudio delete gradle.jar and try
Backup the jar before proceeding.
I got the same issue and this is related to IDE .
Android Studio has to do a fix.
I found the same issue but I found a fix, and all it took was renaming/deleting the .AndroidStudio hidden folder in Windows, under your home directory.
C:\Users\YOURUSERNAME.AndroidStudio
I renamed mine and I'm back up and running.
I could solve this issue in android studio by selecting File-> Invalidate caches/Restart .
Start Android Studio, close any open project.
On the right side, click on Configure -> Settings.
On the left side, in Compiler->Gradle set VM Options to -Xmx512m
Press OK, then create a project. Worked for me.
also because of that
It turns out it's a Windows 8 issue with the available virtual memory. It seems like a few new processes (like Superfetch) eat up a ton of processing power to constantly scan your drive for changes, so searching is faster.
The solution is to change the min and max virtual memory values. Here's how to do that:

I created one android application project in eclipse and whenever I tried to run that application its throwing an error message saying AndroidManifest.xml file is missing. what is the reason for this ?
I am using eclipse with android-sdk and ADT version is 20. in SDK manager I installed android 2.2 API level only.. Is this is the problem for that error ?
Delete bin folder in project and your library dependencies. Then re-run application.
you should clean and refresh your project once.
I was able to fix this by manually deleting the bin directory, as well as the gen directory, right clicking project and selecting Android Tools->Fix Project Properties, then using Project->Build All.
Restart your eclipse and make sure that build automatically checked. It worked for me all the time. Hope this helps some one.
I closed all projects that were unrelated with the one I was trying to run (right-click on project in Project Explorer and then selecting Close Project) and the problem magically disappeared (for no apparent reason). Then, even after I re-opened the closed projects, the problem did not come back.
I put the AndroidManifest.xml that in appcomatv7 and pasted to the project and problem solved
Click project -> Refresh (F5) -> Go to "Project" in the menu bar -> Clean. It works for me.
I was having the same problem and didn't understand why - followed all deletes of /bin, /gen, fixing AVD's, etc, still to no avail.
The /bin got me thinking though -
I had previously used this advice to exclude /bin from the resource filters (in an effort to remove results from the search)....
I removed the filter for /bin and voila.....
Interesting this only affected me when I wanted to Debug or Run within Eclipse -- I could export a working APK without any problem, but debugging failed.
Hope this helps.
I had the problem in android studio after an update , it worked by Tools ->Android ->sync with gradle file
(what worked for me)
1 - copy the file build.gradle
2 - drop the copied file in the android folder [example MyApp/android]
