Android Studio-wont remember new edits and automatically reverts to old versions of files sometimes - android-studio

Every once and a while I have an issue with the new Android Studio. Sometimes while editing, if I make a mistake in one of my files, then try to build it, Android studio will come back with some "Gradle" error. It will then automatically REVERT back to my original code (thus deleting any of my changes). I do not necessarily like this behavior, but I could deal with it.
However... sometimes, in the course of SAVING and editing, it gets into this weird state where Android Studio will REMEMBER the error, and wont let me correct it. I.e. it will keep restoring the OLD version of the file, with the error in it, no matter how many times I try to correct it and re-save it. An example of this is as follows. In the following XML document fragment, I mistakenly added the [android:backcolor="#00000000"] to one of my XML layout files...
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#android:id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceListItemSmall"
android:gravity="center_vertical"
android:paddingLeft="16dp"
android:paddingRight="16dp"
android:textColor="#111"
android:background="?android:attr/activatedBackgroundIndicator"
android:backcolor="#00000000"
android:minHeight="?android:attr/listPreferredItemHeightSmall"/>
After trying to build, Android Studio came back with the following error:
"Error:(1, -1) Gradle:No resource identifier found for attributed 'backcolor' in package 'android'.
Of course, I tried to simply DELETE the offending line that I added to return my code to its original state, before I added the line. I saved it (i.e. save-all/etc...) then tried to rebuild. To my dismay, Android Studio RESTORES the bad version, reinserting the erroneous [android:backcolor="#00000000"] line again back into the file.
I have also tried SAVING (save all) exiting out, going back in, the rebuilding it again, and just about every variation of this. Though the ONLY way that seems that will correct it sometimes is to completely exit out of Android Studio, start it back up again, and try again.
I am guessing that this is really a "feature" and has something to do with source control, and/or Gradle, and that I just don't fully understand it yet. I am also guessing that there is some setting somewhere to adjust and/or correct this - but I am clueless as to what is going on and what to do to fix it.
Is there a way to correct this annoying behavior of Android Studio?

I've had a similar issue when I make a mistake in my strings.xml file, for example when I have an apostrophe without preceding with a '\'. The trouble is that when the build fails, Android Studio automatically opens app\build\intermediates\res\merged\debug\values\values.xml to show me the broken string. If I then try to correct the string in that file, it doesn't do any good because when I try to rebuild, strings.xml is still broken. The crucial thing is to make sure that you're making the correction in strings.xml rather than the values.xml file.

I have the same issue, but i followed following steps and it resolved my issue,
1) Edit your layout file and open the same layout file in notepad, if you can see updated data in notepad then its Studio Synch issue. then re-synch project.
2) If your edited layout file is not reflecting new changes in notepad file then, first re-synch Studio project and followed step 1.
I hope this will resolved your issue as well.

I still have this issue, the only way I have found to fix it is to go to the terminal in android studio and run
rm -R app/build/intermediates/data-binding-layout-out
Android Studio is failing to delete the last build of the layout, when you try to compile again. Once you do it manually everything is back to normal.

While this issue still occasionally happens (as of currently the latest version is 0.5.+), a simple workaround is to manually edit the xml file with a text editor, then save it. Android Studio will then force resync those files.

To save the latest edits, click on the particular file in project window and select synchronize, and rebuild the code. then the latest edits will be saved.

I just had the same error and made me go crazy
I solved it by copying my project file to another directory and then importing it as a new project and the problem disappeared

I work in Android Studio, and due to system crashes, one or more of the features crashed due to frequent system crashes. How should I restore it?

To complete the question: I believe either this is due to patch update to Gradle or project Gradle settings, but I am clueless.
gradleVersion = '4.2.2'
compileSdkVersion = 31
minSdkVersion = 21
targetSdkVersion = 31
buildToolsVersion = '31.0.0'
com.android.tools.build:gradle:4.2.2
distributionUrl=https\://services.gradle.org/distributions/gradle-6.7.1-bin.zip
I use Android Studio for development.
Version:
After frequent system crashes on Windows 10, due to corrupt memory modules, some of the features crashed. I searched in Google and Android Studio documents for troubleshooting, but it seems that my search keywords were not strong, to get me a relevant solution to roll back Android Studio to a stable state.
.git files corrupted: due to which I could see bad file contents where in fact the codes in the files were intact. What I was seeing in the files was due to .git files that were corrupted.
I simply left the project and cloned it in another directory. With .git restored I saw the files in their original form.
Problem started after that. Though the code compilation to the creation of APK was intact, the LINT worked partially correctly.
I re-installed the Android Studio, but due to the previous installation, there was no change. I want to restore the LINT to the previous state. I have the image to show what is happening.
Some keys and flow of control of Kotlin are not recognized showing unnecessary errors. It is difficult to know whether I am writing the correct spelling (one example for the difficulties I am facing) or not until I build my project.
When my .git files crashed, the code was intact, but show garbled texts in the Android Studio Editor for the same file.
Some Kotlin flow of controls are not recognized by Lint
Update:
Intelliscence and Lint are not working in Kotlin Android:-
Kotlin is unable to find OkHttp's extension method: toMediaOrNull().
I found this link :- Uninstall Android Studio with complete effect
Note: Some sections here will be moved to the question section above, and also some
sections from the above question section are worthy to be moved here in the answer.
Once verified whether this is working successfully, I will update a detailed answer.
Update:
The Lint and the IntelliSense, both are not working, and TODOs are not highlighting, after this solution. Now I don't see any red marks, so it is just like working in a plain text editor, except for the keywords highlighting.
IntelliSense not working:
The Analysis process (top end of the editor screen), never stops.
There is not a single change after I deleted the .gradle and .idea folders in the root folder.
Some of the IntelliSense came back after invalidating the cache and restarting Android Studio.
Following: Rename folders inside your {{user_dir}}/.android
folder.
Step by step, we are coming to a close and only this is left: Some of the newly added variables in the binding (layout) are not recognized while the older widget ids are still recognized (in the camel case (Kotlin), from snake case (layout XML)).
New Ids in layout --> binding, are not recognized:
Old Ids in layout --> binding, are still recognized:
Let me observe this for some time, to see whether it comes to normal and come up with more updates. As usual, I face no issues while building and running the APK on my Android device.

Android Studio automatically undoes class rename

I have an odd issue with Android Studio. Occasionally I will try to rename something (right now it's a class), it will go through the process, rename it, and immediately undo the rename with no information or warning. This extremely frustrating and super odd. Does anyone know why this happens or what to do about it?
I've tried git clean -fdx and invalidate caches and restart multiple times, renaming the file then the class, and renaming to a random name to make sure it's not the name itself, but it won't go away.
Ok, I just broke down and manually created a file with the new name, pasted the old code in, changed the old name to the new name, deleted the old file, and when through and manually fixed all the ensuing build errors. Still not sure what the problem was in the first place, but this did the trick.

Rename Android Studio project causing a bunch of errors and java files missing

Following some links here I tried to rename a project. I went to c:\path\to\AndroidStudioProject and renamed the folder there, then found the .idea file and changed that. Now the project loads but java files are missing! However, on clicking java (in the bar at the top), then com I can see them each with a small red j.
I then looked in module Gradle build where there were 3 files, one with the new name and 2 older ones which stated that they did not belong so I deleted them, copying the compile info into the new one. Naturally on doing a Sync Now I get a bunch of errors.
Why does this have to be such a complex operation? Can anyone assist?
After you rename the folder, open the project in Android Studio. From there, right click something that needs to be renamed (e.g., module, package names, etc.) and use Refactor->Rename from the context menu. Keep doing this until everything that can be refactored is.
You will need to manually change the value of applicationId in the app-level build.gradle. Obviously, things like #string/app_name will also have to be changed manually. I recommend making these manual adjustments from inside Android Studio rather than directly editing the files. That way you'll know immediately if you break something.

Visual Studio 2012 constantly complaining that a file has been modified outside of the source editor

I am working on a parser, using the parser generator ANTLR in Visual Studio. Naturally, ANTLR is continually regenerating certain files. Every single time it does this, VS has a popup saying:
The file has been modified outside of the source editor.
Do you want to reload it?
The answer I want is always Yes to All.
Is there any way to tell Visual Studioto always assume I want to reload auto-generated files, without prompting?
Click Tools then options then under the environment node on the left choose documents then check the box that says Auto-load changes, if saved:
If you are using Visual Studio's internal editor and you know that nobody else is editing the file, you might be wondering why that happens. In my case, I realized I was working on a continuously backed-up network folder, that's why the file got re-saved every time I made a change on it and saved. So, if you can move your file to a local, not-backed-up folder, that might also solve this problem.

Android Studio - Auto complete and other features not working

I installed android studio.. it was working fine. Now all the sudden, none of the auto complete features are working.. I can type anything anywhere no variable checking, no help with functions or checking anything. I can still compile the project and I get errors when that happens.
Can anyone please help me out with this issue.
#1 From Build menu (of your Android Studio), click Rebuild Project option.
#2 Then once rebuild completes, go to File > Invalidate Caches / Restart... and Click on Invalidate an Restart button.
This really works for me.
Source: https://code.google.com/p/android/issues/detail?id=61844#c4
#1 Rebuild is required, because Android-Studio does simply rely solely on Gradle's build-result (without static-analysis support, at least at time of writing, 2022).
#2 Clearing cache is required, because the previous build-result (before above rebuild) may be indexed, which makes Android Studio ignore latest Gradle build-result
(this is a very good speed optimization, but a very bad Developer-experience as well).
There can sometimes be other reasons too, which is why there are many other answers posted here.
You can also check if Power Save Mode on File menu is disabled.
Close Android Studio
Go to C:\Users\UserName\.android and rename the folder:
build-cache to build-cache_old
Go to C:\Users\UserName\.AndroidStudio3.x\system
OR (for Android studio 4 and Higher) go to C:\Users\UserName\AppData\Local\Google\AndroidStudio4.x
and rename these folders:
caches to caches_old
compiler to compiler_old
compile-server to compile-server_old
conversion to conversion_old
external_build_system to external_build_system_old
frameworks to frameworks_old
gradle to gradle_old
resource_folder_cache to resource_folder_cache_old
Open Android Studio and open your project again.
Originally use:
compileSdkVersion 32
targetSdkVersion 32
And an update to 33 appeared, I updated it and the suggestions in the XML no longer appeared, I went back to 32 and now the suggestions appeared.
Close Android Studio
Go to c_users_path_on_windows/.AndroidStudio3.5/system/
Delete the cache folder
Start Android Studio
This works for me.
Most of the times i have seen that the problem is that Power Save Mode is enabled, to disable go to Current inspection profile (lower right corner in Android Studio).
I have not run into this problem personally, but try checking the following settings (File -> Settings or Alt+F7):
Project Settings [name]
Inspections - ensure that Android and Android Lint is checked, or alternately just set it back to default using the dropdown box at the top.
IDE Settings
Editor -> Code Completion - ensure the Autopopup code completion is checked (and check the rest of the settings based on your preference.
Uncheck "Power Save Mode" in "File" tab
If nothing works (like happened with me ) go to your user profile in windows at %userprofile% . You will find folders there (hidden) named with the version of the android studio you are using and prefixed with a dot.
like .AndroidStudio3.1. Just delete that .
Solution: Try disabling "File -> Power Save Mode" in Android Studio (Beta) 0.8.14 - Mac OS X
On windows, the option can be at some other place.
I had the same problem then I recalled that while exploring the new android studio, I switched on the "File -> Power Save Mode" to see what it does?
I disabled the power save mode and all those intelligent features were back.
It turned out that in Power Save Mode, Android Studio switches off the modules responsible for features like Smart Code Completion and Code Analysis.
I had a similar problem where none of the other solutions worked.
Closing Android Studio and then deleting the .idea and build folders resolved the issue.
Disable Power Save Mode and Invalidate Cache and Restart.
For Artic Fox 2020|3.1 Version: Auto Complete Suggestion Problem.
Please Follow the Following Steps:
Close Android Studio
Locate caches folder in C:\Users{username}\AppData\Local\Google\AndroidStudio2020.3
and Delete it.
Open Android Studio Again.
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
This Solution also works if android studio mess up with xml files and java code. Don't! modify your code otherwise IDE won't able to change it to default. If you see such messy code just follow above steps and your code will be fine again.
It's Working
Disable Power Save Mode
Untick Power Save Mode Option ::
File -> Power Save Mode
There is a power saver mode in android studio if accidentally you click on that it will disable code analysis which will reduce the battery consumption and performance will also increase but it will not detect any errors and do auto complete operations.
To disable power saver mode
- Go to File Menu of Studio
- Uncheck The Power Saver Mode
In your IDE code analysis will be shown using an eye symbol at the right corner of your android studio.
If Green means it is enabled and there is no error in your code.
If Red Means It is enabled but there are few errors in your code.
If It is white or blur then code analysis is disabled
Just remove all the folders named AndroidStudioPreview
On Windows:
Go to your User Folder - on Windows 7/8 this would be:
[SYSDRIVE]:\Users[your username] (ex. C:\Users\JohnDoe)
In this folder there should be a folder called .AndroidStudioPreview
On Mac OS X
Remove these files:
~/Library/Application Support/AndroidStudioPreview
~/Library/Caches/AndroidStudioPreview
~/Library/Logs/AndroidStudioPreview
~/Library/Preferences/AndroidStudioPreview
There can be several things which cause this.
Make sure you've write the correct version in targetSdkVersion and compileSdkVersion.
Make sure targetSdkVersion and compileSdkVersion are same.
Other solutions can be:
Invalidate caches & restart Android Studio from File → Invalidate Caches / Restarts...
Clean your project from Build → Clean Project
Rebuild project from Build → Rebuild Project
Make project from Build → Make Project [this process may take some time]
Be sure to check for IDE errors by clicking the button at the bottom right of android studio.
In my case, there was a bad plugin, and the IDE Fatal Errors window prompted me to uninstall the plugin. (I wish I'd known about this feature before spending half a day invalidating caches, deleting folders, and reinstalling android studio with no luck.)
It worked for me.
From menu select:
File -> Power Save Mode
and make sure it's disabled
Go TO Left Side Top File Option
Then Click To Power Save Mode
Disable Power Save Mode That Fix This Issue
In my case, when I switch keyboard language to English, the auto complete works again.
if the autocomplete isn't working for you in Android Studio, just press File and uncheck the Power save mode, it should work fine after that.
if power save mode is already unchecked then first check then uncheck them.
If you have a library project included, make sure the library has the dependencies in build.gradle listed using the api configuration, not the implementation configuration.
Also make sure that the project that includes the library has all the dependencies listed (using the implementation configuration is fine here).
'The file size (2561270 bytes) exceeds configured limit (2560000 bytes). Code insight features are not available.'
Had this issue for days with none of these proposed solutions working before eventually getting this message in yellow under the tabs after adding a line of code. Removing the line of code eliminated the message but not the issue. There appears to be a code size window where you lose insight features but don't get this message, at least for me. Once you go over a certain point the message finally pops up. The suggested solution in a different thread for this issue was to edit 'Help/Edit Custom Properties' to increase the configured limit, but just opening this brought up a dialogue asking if I wanted to create an 'idea.properties' folder so I decided not to risk that approach over eventually cutting the file size.
If sometimes this problem can occur if you misspelled a file extension or make a file without adding an extension.
Check you have added the file extension correctly.
I think that answer may help you.
I'm using mac and suddenly the code completion (^space) not working. There are no errors. Turned out the android studio's shortcut was conflicted with system's shortcut. I don't know why it suddenly happen because it was fine before, maybe there was an update on my Mac.
See below setting for the conflicting shortcut
In my case, C:\Users\UserName\AppData\Local\Google\AndroidStudio2020.3\ just delete caches folder and restart android studio. after deleting this caches folder my problem was solved :)
I encounter with this problem while adding a kotlin library into my project on mac. Changing macbook language to english solved this problem. I also had some weird problems with auto-generated databinding codes, those are also solved.
Try Invalidate caches/Restart from File in Menu Bar from android studio.
Close Android Studio
Go to
C:\Users\YOUR_USERNAME\.android
and rename the following folder to:
build-cache to build-cache_old
then Go to (Android studio lower then version 4)
C:\Users\UserName.AndroidStudio3.x\system
OR (Android studio 4 and Higher) Go to
C:\Users\UserName\AppData\Local\Google\AndroidStudio4.x
or
C:\Users\UserName\AppData\Local\Google\AndroidStudio2021.2
depending on your version and rename these folders:
caches to caches_old
compiler to compiler_old
compile-server to compile-server_old
conversion to conversion_old
external_build_system to external_build_system_old
frameworks to frameworks_old
gradle to gradle_old (if exists)
resource_folder_cache to resource_folder_cache_old (if exists)
Open Android Studio again and the autosuggsion will be fixed.
and You can also check if Power Save Mode is disabled or not from the File menu.
