[android-studio] Error running android: Gradle project sync failed. Please fix your project and try again

Android Studio (1.2 RC0) keeps telling me Error running android: Gradle project sync failed. Please fix your project and try again. How can I find out what the problem is? Unfortunately the solutions from this SO thread did not help.

Its because the gradle is not synced because of many reasons.

Go to project folder and remove .gradle folder and start sync. It will work

Just ignore the error and try running the project anyway. It will fail, but this time you will get a link in the error description. Clicking the link will trigger the automatic update/download of the outdated/missing component.

In my scenario, the project failed to launch two times, each time another API/SDK component being the culprit.

In my case I was just trying to launch a sample project I downloaded, having no clue what API level was being targeted or where to look for this information.

I got this problem on Android studio, there in either sync or build square were this link like blue text about this issue, press that button and it download something that fix this problem

This could be due to Android Studio version conflict of v3 and v4 especially when you import a project in android stdio v4 which was previously built in v3.

Here are the few things you need to do:

• remove the .gradle and .idea folders from the main Application folder.
• import the project in the android studio.
• after the sync finished, it will ask you to update the android studio supported version.
• click update.
• done.

I had the same issue yesterday. After opening the "Android SDK Manager", updating all packages and restarting Android Studio, the project compiled again.

this worked for me:

Step 1: visit Release Notes page of Gradle plugin : https://developer.android.com/studio/releases/gradle-plugin

Step 2: go to File > Project Structure > Project and make sure that your Gradle plugin version is compatible with Gradle by referring to table in link above

I encountered this in a unique situation: had refactored the word "time" to "distance" for one of my variables. And when I did the refactor, accidentally had it change the name of one of my gradle dependencies / implementations.

This is a rare cause of the error, but a possibility. So make sure all your dependencies are properly implemented in build.gradle

Download grade files from this url and extract all in a folder:? https://gradle.org/releases

Open file -> Setting in windows OS or Preferences in mac OS and in "Build, Execution, Deployment"

Click on "Gradle"

Check “Use local cradle distribution” and give that extracted folder path.

Run gradle.bat for Windows OS and gradle file for mac OS in that folder.

Then check “Offline work”.

"your extracted folder path"/gradle-4.10.2/bin/.gradle (for version 4.1.2 you can set your version)

Press OK and enjoy it.

If no error messages are shown: sometimes the command-line gradle shows them. Just go the the command-line, change to the app directory and type

gradle installDebug

or, if the details are missing

gradle --info installDebug

This can provide additional information how to debug the problem.

Delete .gradle folder(root directory) and build folder(project directory) and then invalidate caches/restart android studio, run your project again hopefully it will work. It might take some time for the background tasks. In some countries, you may need to turn on the VPN to download.

1. Goto File -> Invalidate caches / Restart
2. Shutdown Android Studio
3. Rename/remove .gradle folder in the user home directory
4. Restart Android Studio (It will download gradle metadata and data)
5. Gradle build succeed
6. Rebuild project. Done.

it was hard to solve but i did it look go to C:\Users(user name)

delete .gradle file its you didn't see it it may be in hidden files so if you use windows 7 right click then click on properties and click on hidden to be not checked

then the file will appear then delete it i hope this works

It took me some time to resolve this.

• Updated SDK Build-Tool [Didn't help]
• Updated CMake [Didn't help]
• Updated Android SDK Platform-Tools [Didn't help]
• Updated Android SDK Tools [Didn't help]
• Updated NDK [Problem solved]

There was a reason, I didn't want to update NDK. When all else failed, I updated NDK and that did the trick.

It is a very common issue and the solution is very easy... Just update the SDK in SDK manager(see full instructions below)

1. Open Android Studio and go to your SDK Manager(File>Settings>SDK Manager)
2. Check for (-) icon in front of any package and click on it.
3. Click OK to start updating the SDK.

Thanks for asking that question :)

Delete "build" folder from project's root folder. Then do "invalidate cache and restart". This will restart your Android Studio and then build the app again, will solve the issue.

Solution is

1. Connect your computer to the internet

2. Click

Sync project with Gradle files

On toolbar

It will automatically sync the gradle.

Goto File -> Invalidate caches / Restart Shutdown Android Studio Rename/remove .gradle folder in the user home directory Restart Android Studio (It will download gradle metadata and data) Gradle build succeed Rebuild project. Done

It was yelling at me about a line in my xml file (which was perfectly valid and never had problems the entire time I've worked on the project). I deleted the line and even after running again and cleaning and rebuilding it kept yelling at me about the completely blank line. I restarted android studio and removed the .gradle folder and it finally worked. Hopefully someone in my shoes that had all of the other answers in this thread fail them will see this answer and save a few hours.

I had this problem (clicked a prompt to "sync with gradle" on my perfectly valid and working project and it killed everything) and I researched for hours trying to figure out how to fix this, including this thread among many others. I finally found my solution, so hopefully, it'll help somebody (and hopefully they fix this terrible system)

if you have this failure and have other failures too, like "Unsupported Modules Detected: Compilation is not supported for following modules” maybe you need to solve them first and then it will be solved too. that's what happened to me.

It could be that you are using gradle in offline mode. To uncheck it go to File > Settings > Gradle, uncheck the Offline Work checkbox, and click Apply Make sure you have internet connection and sync the project again.

1. Download the latest Gradle package distribution for example (gradle-2.11-all.zip).
2. Extract this zip file in a folder as for example (D://Gradle)
3. Load your project in Android Studio and go to File->Settings->Gradle. Click on Use local Gradle distribution and point it to the folder where you unzipped the latest Gradle project.
4. Restart your project

I ran into the same issue, but then did the following, and my issue was resolved:

• updated Gradle
• installed the latest version of Android studio (mine was out of date)

And that solved my problem.

Note: It also helped me to click on the event log, because it has more detailed info about errors. https://developer.android.com/studio/releases/gradle-plugin#updating-plugin also has great info.

I had the exact same error message

Error running android: Gradle project sync failed. Please fix your project and try again

, but if none of the above fixes your error, then I would highly suggest for you to check your syntax inside the AndroidManifest.xml file.

That fixed if for me. I don't understand why the error-message is so misleading, since it had nothing to do with the build gradle directly.

Please also see this SO-answer here, which has lead many of us in the right direction.

None of these answers worked for me, so I uninstalled Android Studio, and reinstalled it. (I did not delete settings) It now works perfectly.

it looks different from one situation to another. for me i did an installation and update a lot of things that the sdk manager said to then i had this problem. all i did was: from file -> Invalidate caches/Restart (a dialog will pop-up) choose Invalidate and restart.

after the restart is done. everything was fixed but i needed to create a new emulator and delete the old one. (android studio 1.3.1) (one professional must edit this to be more understandable) . . . Here everything was fine, but your machines also needs restart because some system files are changed, to sync them we have to restart the system.

Go to

file->settings->build,execution,deployment->gradle.

(and set gradle home path from your directory)

Apparently, some platforms could be missing. This is how I solved the problem:

Do you see an error message that is shown at the bottom of your Android Studio window? It could be a smaller window on the bottom right also.., which looks like:

Now, Click on that blue link, do as the dialog boxes say (if any)...

That solved the problem. Hope it helps...

If your got timeout, Check Gradle Scripts -> gradle.properties in Android Studio, I found that I do have set a socket proxy in Android Studio settings, but in this gradle.properties file, my proxy became to http, so I just removed this http proxy setting lines, and finally works.

I got this error going from Gradle 3.5.3 to 5.4.1 (Android Studio prompted and I clicked "Upgrade".)

Gradle proceeded to upgrade but yielded some errors such as:

ONFIGURE SUCCESSFUL in 1m 27s
ERROR: The Android Gradle plugin supports only Crashlytics Gradle plugin version 1.25.4 and higher.
The following dependencies do not satisfy the required version:
root project 'Android%20App' -> io.fabric.tools:gradle:1.25.1
Update plugins
Affected Modules: app

INFO: API 'variant.getExternalNativeBuildTasks()' is obsolete and has been replaced with 'variant.getExternalNativeBuildProviders()'.
It will be removed at the end of 2019.
For more information, see https://d.android.com/r/tools/task-configuration-avoidance.
To determine what is calling variant.getExternalNativeBuildTasks(), use -Pandroid.debug.obsoleteApi=true on the command line to display more information.
Affected Modules: app

INFO: The specified Android SDK Build Tools version (27.0.3) is ignored, as it is below the minimum supported version (28.0.3) for Android Gradle Plugin 3.5.3.
Android SDK Build Tools 28.0.3 will be used.
To suppress this warning, remove "buildToolsVersion '27.0.3'" from your build.gradle file, as each version of the Android Gradle Plugin now has a default version of the build tools.
Install Build Tools 28.0.3, update version in build file and sync project
Affected Modules: app

The thing that fixed it was opening Settings --> Appearance & Behavior --> System Settings --> Android SDK and I then selected some recent versions of Android SDK like 8, 9, and 10. (I had only had 5.1, 6.0, and Android N Preview installed.)

Once that's installed, I had to modify my build.gradle file for my Module: app

• Removed buildToolsVersion '27.0.3'

Then I clicked the "Sync Project with Gradle Files" button on the toolbar. The Sync output window offered an option to "Update Plugins" and once I clicked through that everything seemed to work. For good measure I again clicked "Sync Project with Gradle Files" followed by Build --> Clean Project, and finally I was able to run my project again.

Resolution is simple. Open the "Android SDK Manager", update all packages and then restart your Android Studio. After that you project should compile without any issues.
