Gradle build for an app in Android Studio generates the following error:
Error:Execution failed for task ':app:compileDebugJavaWithJavac'.
> java.lang.RuntimeException: failure, see logs for details.
cannot generate view binders com.sun.tools.javac.code.Symbol$CompletionFailure: class file for android.view.View$InvalidateInfo not found
Could anyone offer a tip on where to find the logs?
Initially I thought this was such a rudimentary question that the simple answer would pop up at the top for a quick search, but I failed to find it.
Please note this question is about the logs, not for this specific error. This error message is used just as an example. In case you are curious, this specific error was caused by not using the latest version (23) for compileSdkVersion in the build.gradle.
Gradle does not redirect its logs in a separate file in Android Studio.
Therefore if you want to view them in a file, you need to build gradle using a command in the terminal and redirect gradle input to a file.
gradlew build > myLogs.txt 2>&1
This command will redirect all standard output and error messages from gradle build to a file called myLogs.txt in the project folder.
gradlew build > myLogs.txt 2> logErrors.txt
This command will redirect all standard output from Gradle logs to the myLogs.txt and all error messages to logErrors.txt
Tested on Windows 10 and works perfectly.
Here is more information about how to redirect standard output from commands to different files.
View -> Tool Windows -> Build.
There is small "ab" button on the left panel.
All gradle logs for current build are there.
EDIT: There is new icon from AndroidStudio 3.3
You can also try running your task like this:
>gradlew --info build
You will get a bunch of useful log information
In Android Studio 4 (at least 4.2.1 now), both the ab button and the Toggle View button (mentioned in another answer) are gone, so Android Studio doesn't show the logs in the Build View anymore, but if a gradle sync fails, there is a button that brings you to view the idea log outside Android Studio (see the right-most button below), entitled "Show Log in Finder" (at least, in MacOS Android Studio).
In the Windows version of Android Studio, there should be a "Show Log in Explorer" link that will reveal the Gradle log:
Ashakirov's answer is almost the ultimate one. Just a little update, in newer Andy Studio release, e.g. Dolphin (2021.3.1 Patch 1), the "/ab" icon is gone. "Build Analyzer" is a new tab introduced in "Build" tool window, to take place of "/ab". Just select and run "Build"->"Rebuild Project" from the menu, and after the build finish, choose "Tasks" option from the top-left drop-box in "Build Analyzer" tab in "Build" winodw, and Andy Studio will show all the Gradle tasks been run in the build.
P.S. Ajaxian's answer is good for CLI in "Terminal" window though.
I am able to build the app properly, but when I run it I get this error:
This version of android studio is incompatible with the gradle version used.Try disabling the instant run
You can use normal build run rather than instant run.
Check first
Go to Settings/Preferences > Build, Execution, Deployment option > Instant Run and uncheck all the three boxes.
Upgrading Gradle services URL:
Project > Gradle > Wrapper > gradle-wrapper.properties
Change URL from
distributionUrl=https\://services.gradle.org/distributions/gradle-2.10-all.zip
to
distributionUrl=https\://services.gradle.org/distributions/gradle-2.11-all.zip
(Find latest distributionUrl gradle plugin version Here: http://services.gradle.org/distributions
**Make sure to use gradle-x.xx-all.zip
)
Delete your build folder
When you run project, build folder will be created automatically
Go to BUILD option in menu > Clean the project, Build the project
It should work without instant run.
I had easy steps & correct way also
1 - In Settings -> Build, Execution, Deployment option -> Instant Run
2 - Clear Enable instant run to hot swap code
3 - Clean project
p/s : It should totally work.
The Gradle Plugin used is typically the same as the version of Android studio you are using.
Check the Android Studio version
Help → About
and the version will read
Android Studio Version X.Y.Z
Then, go to
Project → Gradle Scripts → build.gradle(Project)
and under dependencies change the classpath to
classpath 'com.android.tools.build:gradle:X.Y.Z'
and rebuild/sync the project.
You can disable instant run by follow these steps in Android Studio:
File → Settings → Preferences dialog → Build → Execution → Deployment
→ Instant Run → Update Project
This feature introduced in Android Studio 2. however, when you disable it, next time when you try to push new app to your emulator is running much slower.
In my case I just update Android Studio to the latest build from canary channel and it's works without disable this feature.
Hope it's help
As commented by sjd: Just cleaning the project and build again might help if you, just like me, have used the automatic update applied by android studio.
I just did a Build > Clean project and then reRun app!
I wanted to run the app in debug mode and got the same message, so I tried:
File > Invalidate caches and restart...
Clean project
Build project
Nothing worked...
Then, I just clicked on the green arrow to run the project without debugging...
Worked!
So then I just added a debugging session with the option left of the stop button in Android Studio.
I did fix by this way.
Update your classpath to classpath 'com.android.tools.build:gradle:2.0.0' in your top level build.gradle file.
Done
I just Deleted the Build Folder and Clean project.It worked for me...!!!
In Android Studio 2.3.3
File -> Settings -> Build, Execution, Deployment -> Instant Run -> Unable Instant Run to hot swap code (Uncheck it)
Now, you have disable Instant Run...
It will solve Instant Run issue.
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.
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.
Solution is
Connect your computer to the internet
Click
Sync project with Gradle files
On toolbar
It will automatically sync the gradle.
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.
Download the latest Gradle package distribution for example (gradle-2.11-all.zip).
Extract this zip file in a folder as for example (D://Gradle)
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.
Restart your project
It is a very common issue and the solution is very easy...
Just update the SDK in SDK manager(see full instructions below)
Open Android Studio and go to your SDK Manager(File>Settings>SDK
Manager)
Check for (-) icon in front of any package and click on it.
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.
Go to
file->settings->build,execution,deployment->gradle.
(and set gradle home path from your directory)
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.
I had the same issue yesterday. After opening the "Android SDK Manager", updating all packages and restarting Android Studio, the project compiled again.
For me, the problem was the SDK Tools License had not been accepted. Clicking on the "Build" tab at the bottom uncovered the issue.
From there, I went into the AVD, uninstalled the tools and then reinstalled them, which prompted to accept the license.
All of these have not worked for me, what did is reading the very bottom of the log file located around here
C:\Users\madri\AppData\Local\Google\AndroidStudio2020.3\log\idea.log
and it said the following
So i fixed the problem by going into Tools > SDK Manager and installing the required SDK version
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.
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 exact same error message
Error running android: Gradle project sync failed. Please fix your project and try again
Steps to solve:
Close Android Studio.
Remove the .gradle and .idea folders from the Application folder.
Open Android studio with your project.
After these steps android studio gradle will sync and download the required files to run the project (don't forget to disable offline mode).
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.
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.
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 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
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've installed Android SDK Command-Line Tools from SDK Manager and after, juste Sync again and all is worked well.
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 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.
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
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...
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.
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.
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)
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
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.
