I changed the name of the Android Studio project folder in the Windows Explorer before I started Android Studio. Bad idea.
Now I get the error:
Gradle sync failed: No toolchains found in the NDK toolchains folder for ABI with prefix: mipsel-linux-android
And all my Activity files are replaced with one MainActivty that doesn't contains the things I've made.
Unfortunately I can't get a previous version with "show history" in Android Studio and i can,t get an older version via windows explorer "restore previous version"
I also tried to decompile it from the .apk on my phone. I got the layout and xml files but can't find my java classes.
I worked since weeks on this project and don't want to lose it.
Can anyone help me either fix the error or restore the .apk?
Thanks so much for all suggestions and ideas
First close the broken project this can be done with File > Close project
Then you have to reopen the project from the new location ie. the renamed folder.
File > Open... browse in your filesystem for the project, select the folder and press OK
Wait for the gradle to sync and hopefully you won't have any problems!
I have the same problem when updating ndk-18. You updated the NDK to version 18 and it is missing the folders/files. You can download ndk-v17 manually and extract the search folder "toolchains" to copy the missing folders/files to your folder android-sdk/ndk-bundle.

what is the actual root cause of this issue? I already sync with gradle files but eventually failed.
Just sync your project with gradles. File --> Sync Project with Gradle Files
Build -> Clean Project
Build -> Rebuild Project
File -> Sync project with gradle files . If not worked then try
File -> Invalidate Caches / Restart .
It's work for me !!!
That could be fixed in one or two steps, depending on how nice is Android Studio today:
Try to sync your project with gradle files:
If that doesn't work, invalidate Android Studio caches and restart. That should fix the problem:
The reason behind the first solution not working could be related on gradle cached dependencies problems, but who knows 🤷
This error mostly occurs when you're trying to open Android App from existing application and probably developed using different computer.
Almost all the troubleshoot methods like File->Sync Project, Build->Clean, etc. Might not work.
This is applied only if you are trying to open the Adroid Application from existing application.
The proper way to evoid errors is only to open sub folder from the path not the root folder. Below is the example of how to properly open the Android application from existing application.
For example in your Message_App/messages/msg path, you must open msg folder not your Message_App folder.
Message_App/messages/msg
>msg
>manifests
>java
>res
Just you have to do >> open File --> Sync Project with Gradle Files
and then after >> open File --> invalidate Android Studio caches / restart so done this problem.:)
sometimes Sync project with gradle File dosent work; you should check the compileSdkVersion in the "build.gradle" file , make them is the same number within all library/modlue
This issue is because the gradle file is not found when starting the project. To fix this ensure your connection to the internet is stable during project startup, the gradle file is downloaded automatically, after a successful download, You should be good!
Issue happened to me when I changed the res>values>styles.xml
What I change was
"Theme.AppCompat.Light.DarkActionBar" --->>> "Base.Theme.AppCompat.Light.DarkActionBar"
Solutions I tried.
Build -> Rebuild Project (Not worked)
Close all files and Open again. Then
Build -> Clean Project (Not worked)
File -> Sync project with gradle files (Not worked)
Close the Android Studio while project still opened. Opened it again. - It Worked.
If nothing of the above steps work, Then simply undo the changes that you have recently made, and then build gradle.
In my case, I have added one dependencies and this problem raised, so I removed that dependencies build the gradle and then again add it.
Problem Solved..!!
I had this problem and it was because I didn't have the right API level installed (and I was also getting an error to that effect). I went into Tools --> SDK Manager and installed the API the system was telling me I needed (in my case, 30). I did that and restarted Android Studio and was able to get into XML files.
After I open a new project in Android Studio 2.3, I receive an error such as:
Gradle sync failed: Cause: services.gradle.org
Googling just gave me a log file on an issue tracker page. I have tried uninstalling/reinstalling. I am not behind a proxy and I've already set:
Use default gradle wrapper
Restarting Gradle sync stops at
Refreshing Gradle project
I can't find anything to fix this problem.
I am running Android Studio on Windows 8.1 with JRE 1.8.0
I Guess This Can Help You.....
https://gradle.org/install
// for manual installation
to get the gradle distribution visit
https;//gradle.org/release
STEPS
1 Dowmload the gradle
2 unzip the pack.
3 create a new folder in your C drive and name it gradle
4 place the unzipped pack into the folder you created
5 Now set the path for your gradle in Android Studio to the just created folder
6 Add the path of your gradle to the System Varaibles.
7 Computer, right click >Properties>Advance System Settings>Enviroment
Varaibles>System Varaibles.Path>Edit.
Hope its Helpful
I also faced the same problem. You have two ways to solve this.
First one is to connect to the Internet and download a new version of Android Studio and the required packages.
Note: You should have "proxies" and "offline work" options enabled.
The second way is to go to file > settings > build > gradle and do the following:
Uncheck the "offline work" option.
Use local gradle distribution and then set the path.
Note: When you have "no proxy" option checked with "offline work" then you have to provide path for every new project.
I had the same problem. so i followed this https://docs.gradle.org/current/userguide/userguide_single.html#installation
finally i got it !!
Android Stidio v 3.0.1
I have this issue and have tried reinstalling to no avail.
What I found was useful is to look in my home directory (on Ubuntu) and open the .gradle folder and open the matching sub folder and delete the lck file and then manually download the desired gradle version (url distributionUrl value) and place the downloaded file in the folder that had the lck file.
Have attributed this problem to using usb tethering for internet..
I am trying to import this project, even I tried to import other few projects too, I am getting below error.
https://github.com/ashdavies/data-binding
I have spent my 5 hours on it, even I tried many solutions on google but nothing gonna worked for me.
I tried following solutions, nothing worked.
1) delete .gradle directory
2) Restart IDE,
3) I tested with com.android.tools.build:gradle-experimental:0.7.0-alpha1
I am frustrated because of this Gradle and these issues.
Gradle Version : Gradle-2.13, I do not want to change this version.
Android Studio Version : Stable 2.1.1
Note : My other project is working fine and I can build it too.
You can try different workarounds for this problem :
1- Clean project and Rebuild it.
2- Before importing the project, remove the contents of the Build folders.
Then replace the contents of your gradle-wrapper.properties file with the following lines, to make it use a local distribution for building the project :
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=file\:/opt/gradle/gradle-2.13-all.zip
in which, the last line prevents android studio to download or use a corrupted gradle cache.
Go to any browser
type gradle and press enter
you can specify any version you want after the
gradle keyword
i am downloading gradle 3.3
https://services.gradle.org/distributions
click on this link which is in description directly if you want
click on gradle 3.3 all.zip
wait for the download to complete
once the download is complete
extract the file to the location
c://user/your pc name /.gradle/wrapper/dists
wait till extraction it takes 5 mins to complete
Now open your project in android studio
9.go to file > settings >bulid ,exec,deployment > gradle
now change use default gradle to
use local gradle distributn
select the location where you had extracted gradle 3.3.zip
C:\Users\your pc name.gradle\wrapper\dists\gradle-3.3
click on OK
Now build starts again and
you can see now the build is successful and error is resolved

In my case, it was happening because i haven’t set the JDK path in environment variable.
Please check from your Android studio studio that your JDK path is correct.
Go to Project Structure> SDK Location and check JDK Path. Give it the correct JDK path and also set the JAVA_HOME environment variable.
You can try this solution as i was facing this issue showing Error2 Gradle's dependency cache may be corrupt and gradle build not working and resolved it. Already answered this question on stack. You can reffer to this answer link
It includes firstly downloading latest graddle version from official site then replacing that unzipped file with home/yourUser/.graddle/wrapper/dists containg older version file on Mac.
Because your gradle path for project is incorrect.
Go to
->Settings
->Gradle
and select "use default gradle settings"
and than sync project. and issue will be resolved.
delete .gradle, .idea and gradle folder from the project and then invalidate cache and restart.
problem will be resolved.
Thanks :)
Sometimes it's a cache issue and sometimes due to interruption in download.
Step 1:
Try to download gradle distribution manually
https://services.gradle.org/distributions/
and then go to project settings -> gradle -> and use the file which you've downloaded
Step 2:
If step#1 still not working, then it may be a cache issue. If you are a mac user, go to your finder user folder, show hidden items by pressing [Command + Shift + .] , Go to gradle folder and
In my case is that gradle-5.1.1-all.zip download failed, so I go to zipStoreBase+zipStorePath(configured in gradle-wrapper.properties, eg: E:\gradle-home\wrapper\dists), and delete the gradle-5.1.1-all directory, and let android studio to download that zip file again.

This error gives when I want to rebuild a project or clean project or run project.
Please someone help me...Thank you...
Don't use Gradle with a fresh version of JDK. It may not support it. In my case, downgrading JDK solved the issue.
You should delete "scripts" folder from "C:\Users\user.gradle\caches\2.4\" via this answer. Then refresh gradle from Android Studio. This worked for me.
You may have opened Android Studio twice. In that case close one of the instances and click on Try Again or Synchronize Gradle, or restart Android Studio. It is because the gradle build was not completed and other dependencies like classpath did not initialize at startup.
You should check android studio power save menu in file. If it was previously selected, then it should be unselected the power save mode in android studio in file menu. I hope it will be worked.
In my case I have deleted .gradle folder and clean the project on re run the project was working fine.
Close the android studio
Delete this file from your pc C:\Users\Avishek\AppData\Local\Temp\asLocalRepo14.gradle
Delete folder from your pc C:\Users\Avishek.gradle\caches\2.2.1
Your app in .gradle and .idea file is also delete
And start your android studio

The last time I worked with android was about a year ago and I'm trying to use this VR project to get back into it. All I want to do is mess around with the app to get a feel for it.
However, I haven't been able to get it running. I installed a fresh copy of Eclipse (juno) with the JDK and android SDK and got the android 4.4W stuff from the SDK manager. I also made a Nexus 5 AVD.
My problem is that I've tried choosing multiple 'root' folders to 'import as existing android project' and none of them have been runnable. Each time the eclipse terminal gives an 'Installation error: Unknown failure' error after installing 'MainActivity.apk'.
I figured the 'main' folder would be most likely to work since it has the manifest and all the other folders associated with android projects.
How do I get it running?
#CommonsWare: I have the project up and running on Eclipse(Juno) with Android 4.4.2
#ThroatOfWinter: These steps should help you. They worked for me.
Download the project from github as a ZIP file
Extract the contents of the ZIP file (named cardboard-master) into a folder and then import the whole folder into Eclipse as a new android project
Create a new "libs" folder in your project
To use the Cardboard API, download the VR Toolkit .jar file and include it in your project in the "libs" folder.
If everything has worked fine so far, you'll find that the "src" folder in your new Cardboard project is empty but the "java" folder contains 3 .java files.
Create a new package in "src" called "com.google.vrtoolkit.cardboard.samples.treasurehunt"
Copy the 3 files from the "java" folder and paste in the package you created in the previous step.
Clean and build the project
Test on an android device (preferably) with the cardboard app installed
You shouldn't need to edit the manifest at all.
That is not an Eclipse project. It is for use with Android Studio and Gradle. Your choices are:
Switch to Android Studio, or
See if somebody else has already reorganized that code into an Eclipse project, or
Attempt to reorganize it yourself, moving the contents of src/main/ into appropriate locations and fixing up the manifest for things that are set now in build.gradle, or
Find something else as a project to get back into Android development
This alternative worked for me: https://github.com/raasun/treasurehunt
It's pretty much the same as the Cardboard sample project from Google except that it's compiled with Eclipse/ANT instead of Android Studio/gradle.
Just follow the first part of moyheen's instructions to set it up.
To make it work on Eclipse, I just placed the Cardboard API jar (cardboard.jar) at the root folder of my app (alongside AndroidManifest.xml), and then in Build Path dialog I just did "Add Jar" and selected cardboard.jar.
Warning: Placing cardboard.jar in libs/ folder won't work, I tried, and it will produce an invalid APK that can't be installed.
