I am trying to build a ionic project in Android studio on Ubuntu 20.04 . I am using the command ionic capacitor build then android studio opens up as expected then it shows this error Gradle sync failed: Sync failed: reason unknown. I am unable find a solution for this particular gradle sync error. I have reinstalled Ubuntu and other things but still the problem persists.
In my case, a fresh install of Android Studio resulted in Android 31 being the only SDK available but the project was targeting Android 30. I went to Tools > SDK Manager and made sure the appropriate version of Android SDK was installed and available. After restarting, and allowing the gradle sync to complete I was able to build/run the app on a virtual device, etc.
Here is what I found
This is the screenshot thanks for helping.
Capacitor lets you manage your own Android project. Like any IDE-backed project, sometimes things get so out of sync that the only solution is to rebuild the project.
To do this, follow these steps:
Copy any source code you created (such as Java files in app/android/src, manifest files, or resource files) into a safe location outside of app/android.
Next, make sure you are running an updated version of the Capacitor CLI:
npm install #capacitor/cli#latest
Remove the android directory:
rm -rf android/
Re-create the Android app from Capacitor:
npx cap add android
Copy your saved source files back into the project.
Check the error log. You should find something like "Module: 'mobile' platform 'android-30' not found" or something similar. Click Tools > SDK Manager and download the appropriate Android SDK Platform package.
on top right you will see option to view log file upon clicking there you will redirect to file manager and open idea file there
example :
open idea file and scroll down you will see actual issue.
In my case android sdk 31 was not installed.
I installed android sdk 31 from File>Settings>Apprearance and behaviour>system settings>android sdk and install required android sdk and rebuild the project.
accord to my observation in most cases you get this error because you have not required sdk installed in your system.
I was downloading an update for android studio. After the download was finished, there was some issue and the patch was not applied. Is there a way to use that downloaded file again? I don't want to download again because it will take a lot of time.
PS I'm using ubuntu.
To solve the “failed to apply patch” Android Studio problem you can follow these steps:
Move the Android SDK folder out of the Android Studio folder (quit Android Studio first).
Redo the Android Studio update process.
Once the update is complete, you will be prompted to enter the new location of the Android SDK.
If these steps do not work for you, update your Java runtime engine (JRE) and development kit (JDK) to the latest version. Alternatively, you could also just download the latest Android Studio build, install it (after renaming the folder of the previous build), and import your projects from the old buggy build.
I am getting the error "Failed to find Build Tools revision 25.0.2" but when I go to android SDK manager, over to SDK Tools, check 'show package details', under Android SDK Build-Tools, it shows 25.0.2 as installed.
It is installed in {USER}/Library/Android/sdk/build-tools/
I'm running Android Studio 2.3.3. Is there anything obvious I'm doing wrong?
Fixed by invalidating cache & restarting (in file menu)
In file build.gradle you have to change the line:
buildToolsVersion:{version} to
buildToolsVersion:25.0.2
as pointed out here:
Gradle sync failed: failed to find Build Tools revision 24.0.0 rc1
Ensure that google maven is added to your project build.gradle:
maven {
url 'https://maven.google.com/'
name 'Google'
}
and buildToolsVersion:25.0.2 is updated to 25.0.3 (or newer)
Go to run my app and i get the following errors in the log.
Error:Could not run build action using Gradle installation 'C:\Program Files\Android\Android Studio\gradle\gradle-2.4'.
Log states the following "Gradle sync failed: Could not run build action using Gradle installation 'C:\Program Files\Android\Android Studio\gradle\gradle-2.4'.
Consult IDE log for more details (Help | Show Log)"
Would anyone kindly tell me how to rectify this problem.
There are two options for you
option 1-update the gradle:
i-Get latest version supported by Android Studio from: http://www.gradle.org/downloads
ii-Extract the gradle file and install to dists folder(gradle folder): default location is: C:\Users[username]\gradle\wrapper\dists
iii-Open Android Studio: File/Settings/Gradle/Service directory path: (Change to folder you set above) and Click ok.
iv-restart Android Studio.
Option 2-Delete the .gradle folder:
default location is:
C:\Users[username]\gradle\wrapper\dists
after that open Android Studio and make a new project (might need to restart).
How to set gradle home while importing existing project in Android studio. While trying to import I need to set up this path.
The gradle plugin (which contains a bundled version of gradle) should be already installed in where/you/installed/android-studio/plugins/gradle so you shouldn't need to manually download it. Depending on the version of Android Studio, that last directory may be where/you/installed/android-studio/gradle/gradle-x.y.z (x.y.z is the version, so check your filesystem for the exact path).
If you intend on doing gradle development outside Android Studio or want a different version, you can download it separately and point it at that path, but if you only want to get Android Studio working with the bundled version, this path should do it.
For Mac OS, you can use the following -
/usr/local/opt/gradle/libexec/ or more generically - path/to/gradle/libexec/ - this is recommended. (the first path is what's achieved after installing gradle via Homebrew)
/path/to/android/studio/plugins/gradle - I don't recommend this because this version of Gradle might be out of date, and Android Studio itself might say it's incompatible.
You should be able to find it in C:\Program Files\Android\Android Studio\Gradle\Gradle 2.2.1. This is running Windows 7 64-Bit. Android Studio 1.0.2.
OSX (Less han two minutes)
Open terminal
Check if Gradle installed gradle --version, if so, goto step 4
If not brew install gradle and Goto step 2
Copy /usr/local/opt/gradle/libexec/
Paste it in Import Project Window in Android Studio > Gradle Home
Important, Celebrate!
Download Gradle http://www.gradle.org/downloads
Install
Set Gradle home to the install directory
On Linux run: whereis gradle.
For me it was /usr/lib/gradle/1.10.
I ran into same problem. I selected location C:\Program Files (x86)\Android\android-studio\plugins\gradle as Gradle Home
In Ubuntu 14.04 after $ sudo apt-get install gradle
I've got
$ whereis gradle
gradle: /usr/bin/gradle /usr/bin/X11/gradle /usr/share/gradle /usr/share/man/man1/gradle.1.gz
The path to Gradle was /usr/share/gradle
For Mac,
/Applications/Android Studio.app/Contents/gradle/gradle-3.2
Download Gradle as described above, but make sure you download version 1.9 and not the current release (1.11). I just had the same problem and downloaded the current release only to have Android Studio tell me it wasn't supported.
On Arch Linux I could not find it, so I added:
echo $APP_HOME
to /usr/bin/grade (found over which gradle)
The Install dir for me was /usr/share/java/gradle/
For migrating from eclipse to android studio
(Do not need to specify the Gradle home.)
Locate the project you exported from Eclipse, expand it, select the build.gradle file and click OK.
In the following dialog, leave Use gradle wrapper selected and click OK.
Try this for windows users

I tried byteit101's solution but whether I chose android-studio-path/plugins/gradle or android-studio-path/plugins/gradle/lib the IDE said it isn't correct.
Then I changed the gradle home to android-studio-path/gradle/gradle-x.x.x and it works.
Mac OSX / Linux
Step 1: Open terminal :)
Step 2: Open .bash_profile in vim to edit:
> vi ~/.bash_profile
Step 3: Add line:
> export GRADLE_HOME=/usr/local/opt/gradle
(for me it was this location, it can be different for u)
Step 4: Add line:
> export PATH="$PATH:$GRADLE_HOME/bin"
(to export bin directory of gradle)
Step 5: Verify by reopening the terminal or new tab, and check by echoing:
> echo $GRADLE_HOME
On Linux Mint 17 it was
/usr/share/gradle
for me
If you are on a Windows machine, go to the directory:
C:\Program Files\Android\Android Studio\gradle\
Click the gradle-4.4 folder from Android Studio\File\Settings, and then click the Apply button.
This is my solution on AndroidStudio/Idea for Mac
$ env | grep GRADLE
GRADLE_HOME=/usr/local/Cellar/gradle/2.6
GRADLE_USER_HOME=/Users/leon/.gradle
I used umake to install android studio. For me the path was
/home/user/.local/share/umake/android/android-studio/gradle/gradle-2.14.1
I had to use this
"C:\Program Files\Android\Android Studio\gradle\gradle-4.1"
Change the version if you have a different one.
I am using Lubuntu, I ended up finding it in :
/usr/share/gradle
Don't need to download or specify anything...
Just go to the install Android Studio plugins Path and search for any file like gradle-wrapper-x.xx.jar (x.xx = version number). Copy it to a subfolder of your project root folder named : gradle.
Example :
- file found gradle-wrapper-1.12.jar in plugins folder of Android Studio Install's path
- my project was on D:\android_repo\myProject
- created a folder into D:\android_repo\myProject\gradle
- copy gradle-wrapper-1.12.jar to this folder D:\android_repo\myProject\gradle
- import again my project and no more question about gradle.
In Windows
..\AndroidStudio2.0Beta6\android-studio\gradle\gradle-2.10
I've stumble across this question, trying to build an Ionic + Cordova app using Gradle from Android Studio installation, rather that installing Gradle separately.
On Centos, the Gradle binary was here: /home/YOURUSERNAME/.gradle/wrapper/dists/gradle-VERSION-all/CUSTOM_HASH/gradle-VERSION/bin
So, I've added export PATH=/home/maxim/.gradle/wrapper/dists/gradle-4.1-all/bzyivzo6n839fup2jbap0tjew/gradle-4.1/bin:$PATH to my ~/.bashrc and ionic cordova run android command worked just fine.
If you are on windows machine, go to the directory C:\Program Files\Android\Android Studio\gradle\ and click the gradle folder and apply it on
This worked.
C:\Program Files\Android\Android Studio\gradle\gradle-3.2
If you're using MacPorts gradle's home is:
/opt/local/share/java/gradle
For Ubuntu default version is /usr/lib/gradle/default.
In case of update, you don't need to reassign link in idea/studio.
For OSX, if going to Finder, navigate to this category: /usr/local/opt/ if you do not see gradle folder, install your grandle version manually:
https://services.gradle.org/distributions/gradle-5.4.1-all.zip
https://services.gradle.org/distributions/gradle-4.4.1-all.zip
If you are looking for specific Gradle version, simply change the version number from the zip links above, unzip and add that in the Gradle folder /usr/local/opt/gradle
If you are on a Windows machine, gradle home is located inside the installation folder of your Android Studio, usually at:
C:\Program Files\Android\Android Studio\gradle\gradle-5.1.1
Change the version if you have a different one.
On Windows it was
C:/Android Studio/jre
