Android Studio shows wrong file contents

android-studio intellij-idea

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.

That's now the fifth post I see in a short time showing how AS 3.2.1 corrupts files. Seems there is a serious bug.

I saw a post with the same problem, if you are using windows Go to C -> Users -> yourUserName -> and delete the folder of the android studio version you are using (mine is .AndroidStudio3.2) It will delete all the settings you've made and maybe the plugins you have installed

Facing the same issue. What the hell is going on?

Using Arctic Fox, and this problem still exist. By now we should call it a "feature" rather than bug.

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.

This worked for me as well. Do you know why or what is causing the issue? And why did you try this out of all things?

Because every setting Android studio has is in these folders, including all the plugins. Once I realized that my actual data wasn't being changed, this seemed like the logical choice.

My laptop got blue screen several times while working on Android Studio with the emulator and the tomcat server running.. I think the blue screen had somehow corrupted the Android Studio cache. Therefore, deleting the cache folder worked for me..

just deleting caches folder: C:\Users\my_user_name\.AndroidStudio3.3\system\caches worked for me.

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

Edit[2021-11-08]: 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.

This is corroborated by a comment on the canonical Android Studio bug report.

Thanks for the solution, this issue happened after opening two projects in a different window and integrated firebase to one of those projects. Now it's loading correctly.

The comment for AS4 really helped. in my case, my AS4 caused by BSOD

I had a power cut while using Android Studio 4 which seemed to cause some files to show the wrong contents. Deleting the caches folder as described here fixed the issue. Many thanks.

One would have thought that "Invalidate Caches" would have done this job. Thank you for the solution.

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.

Heads-up: this answer was merged here from stackoverflow.com/questions/53091670/…

It would, but Hong's is simpler.

Close Android studio and then delete the caches folder: C:\Users\user_name\.AndroidStudio3.4\system\caches

This answer has already been posted multiple times. Please only post an answer to old questions if you have a different solution or a significantly better explanation than existing answers.

This answer worked for me for Android 3.6.3, and was the simplest and least invasive, and not mentioned directly anywhere else in this question thread.

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_ ~/Library/Logs/AndroidStudio[Preview]_X.Y_ ~/Library/Application Support/AndroidStudio[Preview]_X.Y_

Linux: ~/.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.

update android studio is always a mistake... using it is a mistake that google forces us since it can do something decent by itself

You saved my day bro

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!))

Quick and easy solution byHongbelow. In a single step. close AS and Delete everything inside caches folder: C:\Users\my_user_name\.AndroidStudio3.3\system\caches and Enjoy .

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.
