I am a starter in android development and I started off with eclipse.. But it started giving lot of problems. So I switched to android studio. Got it set up successfully and for couple of weeks it was ok. Now, for some reason, the auto complete feature is not working. It is not giving any choices while typing, so I tried ctrl-enter. It says no suggestions. I browsed through similar queries and tried the following.
Disabling Power Save in File menu.
Checking basic complete and smart type completion in IDE settings (editor)
Invalidate caches and restart.
But non of these seems to work.
Try with CTRL + space and you will get the drop down .
I had the same issue and solved it.
Go File> Invalidate Caches / Restart... > Click at Invalidate and Restart
Then you can also check if Power Save Mode on File menu is disabled.
Source: Android Studio - Auto complete and other features not working
These following steps are working for me:
Close android studio
Go to path/.AndroidStudio3.5/system/ delete caches folder
Start Android Studio
You should Try this way File->Invalidate Caches/Restart or you can find solution by using below link

In my case on Android Studio Artic Fox edition there were strange problems with autocompletion and suggestions because of old version of Gradle plugin. I have updated to
classpath 'com.android.tools.build:gradle:4.1.1'
classpath 'org.jetbrains.kotlin:kotlin-gradle-plugin:1.4.21'
and it worked as expected. Hope it will be helpful for new visitors like in my case it would.
In Ubuntu 21 I had tried
$ rm -rf ~/.cache/Google/AndroidStudio2020.3/caches/
I followed all the steps from various answers and sources, still didn't get it to work. Code completion and Syntax Highlighting was not working.
I restarted using Invalidate Caches and did Gradle Sync atleast 10 times.
It was working in main flavor, but not in other flavors! In this project we have multiple flavors.
So finally the solution was found using
Android Studio product flavors only recognized one out of two flavours
Just selecting the correct Build Variant solved my issue.
Delete everything inside caches folder
C:\Users\<user_name>\AppData\Local\Google\AndroidStudio<version_x>\caches
and restart android studio

My project works and builds successfully on my Mac but I cloned from github and although Android Studio appears to work normally, the project wouldn't build. I setup this project using Kotlin DSL.
Gradle sync failed: could not find extension implementation class org.jetbrains.kotlin.idea.scripting.gradle.roots.GradleBuildRoot
Tried invalidate cache, removed all .gitignore rules but it's still the same.
Any ideas?
I had the same issue (Note : Running Linux/Ubuntu 20.04 LTS and Android Studio 4.1.1).
Things I tried that did NOT work and error persisted :
Invalidate Caches / Restart
Reboot
Nuking the .gradle and .m2 folders
Android Studio re-install
Downgrade kotlin gradle plugin from 1.4.21 to 1.4.10
What did work :
Moving the project to a different folder/location on disk and open Android Studio
As soon as I moved the project back to the original location I would start getting the same error. This lead me to believe it was some sort of caching issue, separate from the caches "invalidated".
Solution :
Android Studio / Intellij creates a hidden folder called :
On Linux :
AS : ~/.cache/Google/AndroidStudioX.X
IJ : ~/.cache/Jetbrains/IntelliJIdea2020.X
On Mac :
AS : ~/Library/Caches/Google/AndroidStudioX.X
IJ : ~/Library/Caches/Jetbrains/IntelliJIdea2020.X
On Windows:
AS : %HOME%\AppData\Local\Google\AndroidStudioX.X
IJ : %HOME%\AppData\Local\Jetbrains\IntelliJIdea2020.X
Inside this folder are other various folders, however I removed the relevant workspace file (workspace/[project name].[hashed value].xml) after which problem went away when opening the project again, from its original location.
So it appears that "Invalidate Caches / Restart" does not "Invalidate" all caches!
I hope this resolves you problem!
Update
As this answer has had quite a few upvotes it would appear that this might be a ongoing bug with Intellij. If anyone has this problem, before resolving with the suggested solution consider checking there isn't an open issue on the bug tracker and submitting a new issue : https://youtrack.jetbrains.com/issues
Feel free to edit this update with issue if one is opened.
Update 2
Issue opened by #GeniusRUS :
https://youtrack.jetbrains.com/issue/KT-44937
For Mac users delete the following file:
~/Library/Caches/Google/AndroidStudio4.1/workspace/<your_project_name>.58dfbe93.xml
PS: Thanls #Mark Keen for solution.
basically i deleted .idea folder and then invalidate and restart ... error goes away and built successfull.
This probably isn't the "correct" solution, however, it worked for me. I had to download a newer (Canary) Version of Android Studio to get this error message to go away and to finally build my Android project once again. I found this YouTrack JetBrains issue where people also suggested reverting to previous, known working, versions of Android Studio to get their projects to build again.
This is a SUPER frustrating issue and I hope that one of the approaches resolves your build issues for you!
Here are the Android Studio Versions Download page for convenience.
After moving projects and files around I had also the honor to enjoy this error in Android Studio 4.1.1 (under Windows 10). Unfortunately, none of the above solutions worked for me but they helped me to narrow down the issue.
So, I found that there is a folder with workspaces under:
%HOME%\AppData\Local\Google\AndroidStudio4.1\workspace\
There are a couple of *.xml files named like the android projects. I deleted the one that didn't work.
Then switched back to Android Studio and used the Files > Invalidate Caches / Restart... feature. Android Studio restarted and the problem was fixed.
Bonus: How I found the workspace folder?
I used the Procmon.exe from Sysinternals where I filtered by the Process Name = studio64.exe. I then used the elephant-with-the-arrow button (Sync Project with Gradle Files) in Android Studio. At the end of the recording there was the workspace folder that Android Studio used just before Gradle failed.
I added a "problem" ticket to YouTrack, where I described my case in detail.
The support agent said the issue has already been fixed in the IDEA 2021.1 platform.
And also gave recommendations for this case
Link to issue
https://youtrack.jetbrains.com/issue/KT-44937
I fixed the issue by changing the root project directory name. You can try that.
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
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.
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_
~/Library/Logs/AndroidStudio[Preview]_X.Y_
~/Library/Application Support/AndroidStudio[Preview]_X.Y_
Linux:
~/.AndroidStudio[Preview]_X.Y_
See: https://developer.android.com/studio/releases#delete-unused
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'm not able to create a new project in the android studio. I am getting a warning message
java.lang.RuntimeException: Could not find a
JavaToKotlinConversionProvider, even though one should be bundled with
Studio at
com.android.tools.idea.npw.model.JavaToKotlinHandler.getJavaToKotlinConversionProvider(JavaToKotlinHandler.java:56)
at
com.android.tools.idea.npw.template.TemplateValueInjector.addKotlinVersion(TemplateValueInjector.java:410)
Go to Preferences -> Plugins -> Kotlin and update the Kotlin plugin to the last version even though you don't write your code in Kotlin.
I have the same error, I've juste disabled the kotlin plugin and after restarting the IDE, just re-enable it. After that final restart, every thing works fine.
Go to file and the plugin in android studio and update your Kotlin plugin...
I opened an old project (by old I mean another project) and did everything Android Studio said to give me a successful build (I faced some errors when I tried to build the project that I could build couple weeks ago and actually I fixed them, updating gradle and stuff like that, not code issues of course).
After that I could create new project same as before.
Update seems like in order to keep Android Studio happy we have to keep Kotlin plugin enabled, interesting.
I solved this problem by doing this:
File->Settings->Plugins
Click the Installed tab at the top.
Search "kotlin" and click the result that shows up.
Click Enable at the top right
settings>plugins>check Kotlin >Apply then Ok solved it for me.
It occurred due to migration from Android Studio 3.2 to 3.3
Goto File-->Invalidate Caches/Restart
This will solve the problem.
I've updated Android Studio to version 3.2.
After that update one of my projects don't want to index.
It freezes with the message
"Indexing paused due to batch update".
How can I fix this?
File gradle-wrapper.properties:
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip
File gradle-properties:
org.gradle.jvmargs=-Xmx1536m
org.gradle.parallel=true
org.gradle.daemon=true
org.gradle.configureondemand=true
I faced the same issue with Android Studio 3.2. Invalidated the cache and restarted Android Studio, but it still did not work for me. Then I just re-imported the project and it worked!
Just Restart (File > Invalidate Cache & Restart > Just Restart)
I faced this issue in Android Studio 3.+ when forcefully close Studio in between some gradle process.
Pressing the play button worked for me. It finished indexing and installed the apk in seconds. The catch is that I have to do this every time and batch does not seem to update.
Click on the play button to the right of the progress bar.
Press the play button to the right of this message and the issue would resolve.
You have to do it every time, because right now the problem is systematic and there is no solution to stop it from appearing.
I invalidated the cache and restarted Android Studio. That worked for me.
You can do this by:
File > Invalidate Caches / Restart > Invalidate and Restart
I faced this issue many times and what I did everytime is:
Firstly, click on the processing bar on the bottom of the android studio.
A pop up window will appear on the screen like this-
Click on the red circled Play button and let the process complete.
Please note that you will have to repeat this everytime you face this issue because this is some kind of bug or something in AS version 3.2
Optional: click on (-) minimize button if you want to the pop-up to minimize
I faced the same issue, it seems that Android Studio messes up the cache.
Go to File > Invalidate Caches and Restart
Then on the Pop Up that appears choose Invalidate and Restart
Seems like there is an issue with Android Studio itself. I fixed the issue for now by following these steps:
Click File > Invalidate Caches / Restart
On the pop up choose Invalidate and Restart
Invalidated the cache -> restarted Android Studio -> re-import the project from the project location. Its worked for me
This is an issue in Android Studio since v3.2, I have posted an issue in Android Studio Issue Tracker, it's being finally accepted. Waiting for them to solve it.
Here is the issue tracker, you can follow up from here.
please star the issue as well to help solving it.
Stay Connected to internet.Let the batch to be updated.Wait one time and it will be easy the next time. OR...Click on the play button.
I saw this error and none of the solutions posted here worked for me. I had a specific scenario (see below), and I could get rid of the problem in my specific scenario. Not sure if the OP had the same scenario, by here are my two cents:
In my specific case I had two projects open in Android Studio, where one of the project was from a sshfs-mounted directory (the other project was local to my computer). I believe that made Android Studio throw the "Indexing paused due to batch updated" message on, strangely, both the projects.
To get rid of the error on the local project, I had to close the remote mounted project. On closing that project, the message was gone for my local project.
Hope that helps.
Close your project
Go to your project root directory,
Find and delete the xxx.iml file, the .idea and .gradle folders
Re-open your project using Android Studio.
I had the same issue and I fixed by do the following:
Click File --> click on Invalidate Caches / Restart
You will see a pop up--> select Invalidate and Restart
I did it by exporting the project into zip file and open it like normal. you can export by clicking the file navbar and choose export to zip file
I faced the same Issue but the situation which lead to this was different:
I created a remote branch on the project's repository on GitHub and it was empty.
And then I checkout to that branch locally while android studio was running.
I then deleted the local repository and created it again but this time it was not empty. Further I pushed the code to the remote branch as well.Now I thought that it will start the project normally but again the same happened.it resulted in an IDE error.
To solves this issue I deleted that local repository and again re-imported it.Than it started correctly.
None of the other answers worked for me. Not even pressing the "play" button. All that worked was closing the project and re-opening it via "Open an existing Android Studio project".
The effect only lasts for a single session. As soon as I close and re-open the project, or AS 3.3, the problem re-appears.
Deleting C:\Users\<user>\.AndroidStudio3.3\config\options\recentProjects.xml (before starting AS 3.3) is an alternative way to accomplish the same thing.
EDIT
Upon upgrading to AS 3.3.2, this solution no longer worked. However, after an "Invalidate Caches and Restart", the problem disappeared.
Click on play button twice and then go to file->Invalidate Caches / Restart...
repeat this process every time whenever you face this issue.
I solved it by deleting all the *.iml files and the .idea folder
I faced the same issue, because my AS version is not the same with gradle plugin's version.
This issue coccus randomly in Android Studio V3.+ [Issue tracker:https://issuetracker.google.com/issues/118523471] .
There might be multiple reasons for this issue but it is mainly either ".gradle" related or ".iml" file related IntelliJ/Android Studio configurations.
Possible solutions:
Click on play icon under the processing bar (on the bottom of the android studio). But be aware that multiple clicks may also kill the the indexing process.
Invalidate cache (File -> Invalidate Cache & Restart -> Just Restart)
Clean ((Build -> Clean project) and Rebuild (Build -> Rebuild Project)
Sync Project with Gradle Files: Available options (depending on the Android Studio version) at
Tools -> Android -> Sync Project with Gradle Files
button available at top left corner in Android Studio's toolbar
File -> Sync Project with Gradle Files
Delete the .idea & .gradle folders and .idea & .iml files from the project root directory and re-import the project
I have faced this issue quite a few times and got rid of then by using one or more of above solutions.
But in some scenario nothing of the above solutions may work (as recently I get trapped-in). In this case I have to recreate the same project from scratch and copied back the required files into it. But ideally this should not be the solution. Please let me know if any other possible solution is there.
Invalidate cache and restart did the work for me. Now, the build is compiling in seconds.
I am developing an Android app using Android Studio (0.89 Build #AI-135.1404660, Built on Sept 3,2014) using both emulator and Nexus 4 device.
I had the same issue with a version prior to that.
The problem is that after I changed my code and resource files, I still get the old apk installed on the device or emulator.
What do I need to do to get it to run current code? Is it a building config?
Is it a known issue with Android Studio?
Or with a Nexus 4 device?
This is the second time it has happened, and I resolved it(then) after trying one of the steps below. They have not worked for me again.
Here is what I've tried
Build > Clean Project > Restart Android Studio > Run
Build > Rebuild Project > Run
Step 1 plus Uninstalling of apk on device
Step 2 plus Unistalling of apk on device
Adding erroneous resource entry then running.
I have read the following:
Android apk install: How to clear files from old version?
adb - How to reinstall an app, without retaining the data?
Device still has the old apk
Android build doesn't update code base or resources for target .apk on device
None has worked so far.
I had the same problem. After trying numerous methods that didn't work, I realized that I had accidentally changed an option in my "Run Configuration". Here's exactly what I did to fix the issue.
Run --> Edit Configurations
With your configuration selected on the left panel (mine says "app"), in the General tab on the right panel, there is a section called "Before launch". This section should have an option added called "Gradle-aware Make", but I had accidentally removed it.
I re-added it by pressing the "+", then clicking OK in the popup (leave the input box in the popup blank).
Click apply.
This fixed the problem immediately. Hope this helps someone!
Run / Debug Configurations / Miscellaneous TAB
[] Uncheck: Skip installation if APK has not changed
Android Studio doesn't always detect small changes in code.
The behaviour is erratic. I solved it by reviewing my code.It turned out that there was a resource file that was invalid. Try reverting back to the last working version of your code before the current changes... Probably a known issue that will be/was resolved out of Beta
Google thinks it is a feature, not a bug
https://code.google.com/p/android/issues/detail?id=156263
Their proposed solution is to copy the apk(s) instead of manipulating the filename, as in e.g.
Copying APK file in Android Gradle project
I've spent way too many hours to keep this to myself. The way I fixed it was that I noticed some hours later that I was using different layout version in res/ .... I have actually two versions of layout (layout-v26) and (layout). All this time I was modifying the other one and uploading different one. Maybe its just a newbie mistake but I hope somebody will find it useful.
The reason why there are 2 version was because of " autofillHints="" -> quickfix -> create new version of layout "

I am using android studio for building flutter app, I was facing the same issue untill I did the following:
From Android Studio, go to Tools-Flutter-FlutterClean
It resolved my problem as of now.
Check Your Layout Files.
I ran into the same problem and I realized, it gives some problem if you have same layout in multiple orientations(portrait and landscape). If one is changed other remains unchanged and then it creates a conflict. So android studio installs the one with the previous layout
PS: This was happening in my case.
The problem occurred on my Android 11 devices. I guess ART ran old code dex2oated.
Solution:
Run / Debug Configurations - General - Always install with package manager (disable deploy optimization on Android 11 and later), and check the option.
I was also facing this issue and get solution by deleting build folder manually because some time ide cannot be able to delete this. So go to the app folder and find build folder delete this and after clean and build project and run again.
projectname->app->build
You should select "Deploy default APK" option in Run/Debug Configurations. After that Android Studio will upload and install new apk to your emulator/device when you run application.
In android studio. at right side. see gradle option. click it. and then press circular arrows button shown in red square.
Same problem, none of the solutions mentioned here had any effect. I had to disable the "Allow parallel run" in "Menu > Run > Edit configurations...".
You can read more about this option here: How to run the same project multiple times in IntelliJ IDEA?
The solution to this issue is actually very simple.
Android studio is actually not detecting some small changes that you have made to the application. That is why it is installing the previous builds.
The solution is easy -> Remove the previous builds.
In the right side, go to gradle tab.
Expand Tasks. Find "clean" or "cleanCache" task or any task that starts with "clean". Double click to run that task.
Expand "app". and do the same.
Then File> Invalidate cache and restart.
Enjoy!! Your problem is solved...
My devices also ran old states - dont know from where in my git it has taken these.
I created a new configuration (default is "app") and it worked.
