I want to use some native library. and I am using below dependnecy
implementation 'com.google.android.gms:play-services-vision:10.+'
in build.gradle in flutter project.
How I will sync that dependency. Please help me!
If you're using Android Studio for Flutter development, right click on the android folder in your Flutter project. Select "Flutter" -> "Open Android Module in Android Studio".
Or
Simply start Android Studio and open the Android (sub)project directly.
In any case, once the Android project is opened in Android Studio, you can make changes in your build.gradle. The editor will tell you to sync. Otherwise simply execute a build. Afterwards you will be able to import use your Android classes.
That is the problem with gradle sync of Android project, not with Flutter dependencies.
In your build.gradle of your module (for example android/app/build.gradle of your Flutter project) add:
implementation 'com.google.android.gms:play-services-vision:10.+'
in dependencies as bellow:
dependencies {
implementation 'com.google.android.gms:play-services-vision:10.+'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}
Then open terminal, cd to android folder of your flutter project and run:
$./gradlew build
After that you will be able import com.google.android.gms... in your Java class.
Go to android folder of your flutter project and then
open it in terminal by right clicking on that folder
then try to run below command
gradlew build
i know i am late but let me suggest the way as per i done and it's working , if it helps to someone
Open android studio flutter project
Go to file
Click on setting
Search for "Flutter"
at bottom of that view there is an experiments section do check that both checkbox
after doing this add any dependencies in android gradle and go to file and click on "Sync with file system" and you are done , please check the below screenshot to do check the experiments item
I managed to sync the dependencies using "Run Configurations". Please follow next screenshots:
Open Gradle tab.
Select path to Build.Gradle file.
Double click to sync.
For me it was the kotlin version being specified in the build.gradle, which wasn't in sync with the IDE's version. Changed it from ext.kotlin_version = '1.4.32' to ext.kotlin_version = '1.5.20'. Now it is syncing the gradle script again.

Since I have included the geolocator plugin in my flutter project, the build fails with the message
A problem occurred evaluating root project 'android'.
Basedir C:\Users\<user>\flutter\.pub-cache\hosted\pub.dartlang.org\geolocator-8.1.1\android does not exist
It's true that this directory does not exist but that's the way is done in github project.
do you have implement geolocator for a platform like android or ios?
after you have implemented you can try:
run: flutter clean and try again
Make sure your Android project uses gradle version 3.5.0 and gradle-wrapper 5.6.2.

Exception: Gradle task assembleDebug failed with exit code 1
I recently Solved this problem.
This Problem came from gradle file is corrupted in my system.
I'm using Linux so this steps almost same in windows also. This answer is for any gradle version.
Open File Manager:
enable Show hidden folder from top menu bar.
You may find this location : .gradle>wrapper>dists.
In Linux: Home > .gradle > wrapper > dists.
In Windows: C:>Users>{PC Name}>.gradle>wrapper>dists
Method 1
Go inside gradle-6.5-all > dists > 2oz4ud9k3tuxjg84bbf55q0tn. '2oz4ud9k3tuxjg84bbf55q0tn' may be different in your PC.
Delete all files in that folder and download required file manually: https://downloads.gradle-dn.com/distributions/gradle-6.5-all.zip
after download paste freshly downloaded zip file in that folder.
Run your project flutter run -v
Method 2
Try this if you have fast & stable internet connection.
Delete that gradle-6.5-all folder.
Open project in VS code or Android Studio and open terminal.
Run this command flutter run -v
Method 3
Flutter Doctor will give right result.
Open Android Studio
Create new flutter project
Click on Tools > flutter >Flutter for editing in android studio
and wait, flutter doctor takes time to identify problem.
Use this link for download gradle file.
Replace 6.5 with your gradle version.
https://downloads.gradle-dn.com/distributions/gradle-6.5-all.zip
I hope this answer helpful for you.
Please use the below command
1.Mac User :
rm -rf ~/.gradle
2.Windows User :
remove the .gradle file
.gradle file location -> C:\Users\myUser
I solve this error by updating the gradle plugin/version. I have as part of my configuration:
Windows 10
Android Studio 4.2.1
Java 11: Android Studio 4.2.1 don't have support for JDK 16, so, I installed JDK 11, and configured the AS (how to change the jdk in AS) to use this older JDK
Gradle 7.0.1
By default, when you create a new Flutter project, the IDE created it with basic standard configurations, so you have to change this configs to fit your current config. For that, you need to update the gradle config in the flutter project, as follow:
in android/gradle/build.gradle file: update the gradle plugin to 4.2.0 in the dependencies section, like this:
dependencies {
classpath 'com.android.tools.build:gradle:4.2.0'
//more dependencies
}
in android/gradle/wrapper/gradle-wrapper.properties file: update the gradle version, in this case I have the 7.0.1, feel free to use another one, like this
distributionUrl=https\://services.gradle.org/distributions/gradle-7.0.1-all.zip
//more attributes
After you change the gradle config, run this commands in your project:
flutter clean : clean the project
flutter pub get : update your dependencies
flutter run : run the project. Now it must work, at least it work for me
I faced the same problem in VSCode when I wanted to run the Flutter app I got that error, so after lots of debugging and research, I found the solution. it's pretty easy, just follow these steps:
In windows 10:
1. Open flutter project in a Text-Editor like VSCode.
2. Open android -> gradle -> wrapper -> gradle-wrapper.properties
3. You will find "gradle-6.7.1.all.zip" inside gradle-wrapper folder
4. Go to this path: C:\Users\your-user
5. Then go to the wrapper->dists and find "gradle-6.7.1.all" folder
5. Delete this folder.
6. Then come to VSCode and open Terminal.
7. Please make sure that you have stable internet connection then type this command in terminal
8. flutter run
I hope this solution can help you!
I solve this error by deleting the .gradle folder.
This location is gradle folder
In Windows: C:> Users> {PC Name}>. Gradle
After deleting this folder, you only need to run the application again in Android Studio. At this point, Android Studio starts downloading the deleted folder automatically.
enter image description here
This error is caused by corrupted gradle files, this is either due to incomplete downloads due to network issues. To solve it easily download the gradle zipped file from https://downloads.gradle-dn.com/distributions/gradle-6.7-all.zip and paste on the .gradle directory as shown below if you are on linux
enter image description here
I try all method but it did not work for me so i decided to location the gradle-wrapper.properties in the andriod folder then i change the distribution gradle link to a more recent gradle link.
Welcome SO.
Java 16/latest version is not fully compatible with the Gradle 6 at this moment. Try to use java 11 or 8, it will resolve your issue.
I was working on a Flutter project and everything was working fine until I updated My Android Studio and some of the SDK tools. Then when I was trying to run my project, I was getting the Error below:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:stripDebugDebugSymbols'.
> No toolchains found in the NDK toolchains folder for ABI with prefix: arm-linux-androideabi
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
* Get more help at [https://help.gradle.org](https://help.gradle.org)
BUILD FAILED in 1m 4s
Exception: Gradle task assembleDebug failed with exit code 1
So what have gone wrong? What should I do?
The main reason is that NDK 23 has different toolchain than the previous versions of NDK (22-), so the old version of AGP (Android Gradle Plugin) has not idea where to find the executables for different ABIs.
For me, simply update the AGP version in the build.gradle in your Android project root to 4.0+, such as
dependencies {
classpath "com.android.tools.build:gradle:4.0.1"
...
This will resolve the problem.
Note: You will need to set the environment variable ANDROID_NDK_HOME to your NDK 22- location, even Google's document does not require that or says it is deprecated.
If you want to stick to the current version of AGP, there is another work around, simply add this
android {
android.ndkVersion "21.4.7075529" // (or whichever NDK 22- version you have installed)
...
to your module's build.gradle (not the build.gradle of your project)
Some other ways to work around this can be found here, Configure the NDK for the Android Gradle plugin
Well I solved the issue in 2 different ways:
A. I downgraded my NDK from version 23.0.7123448 to 22.0.7026061 by simple steps below:
1.Open SDK Manager from tool bar of android studio or from settings menu (File --> Settings --> Appearance and Behavior --> System Settings --> Android SDK).
Select the SDK Tools tab and from the Bottom Right of the window check the Show package details. Then simply uncheck any version you want to delete and select Apply.
(For me removing version 23.0.7123448 and get to 22.0.7026061 solved the problem. But if you are still having the Error above try to lower the NDK version. The most stable NDK version is 20.1.5948944)
If you have done all the steps before, you will see the following window popping up. Hit OK and you are all set.
B. This approach might look simple but yet it does the trick. Simply create a new Flutter project and get all you work (lib folder, assets, etc) to the new project.
Environment
OS : Big Sur 11.1
npm 7.24.0
node v14.15.5
react-native-cli: 2.0.1
react-native: 0.63.4
Command
react-native run-android
Error
*What went wrong:
Execution failed for task ':app:stripDebugDebugSymbols'.
No toolchains found in the NDK toolchains folder for ABI with prefix: arm-linux-androideabi
Fix
Checking Android SDK Tools, NDK (side-by-side):
In the android toolbar go to:
Tools >> SDK Manager
![Tools-SDK][1]
Then in the popup aside navigation go to:
Appearance & Behavior >> System Settings >> Android SDK

Click “SDK Tools”
Check the box next to show package details

Solution:
Downgrade

Idea for downgrade: Taba's solution
Here's what worked for me
I updated AGP to 4.1+ in my Android Project root build.gradle
dependencies {
classpath "com.android.tools.build:gradle:4.1.0"
...
AGP 4.1+ supports only gradle version gradle-6.5 above
so I updated the distributionUrl in gradle-wrapper.properties file located in gradle/wrapper folder
distributionUrl=https\://services.gradle.org/distributions/gradle-6.5-all.zip
Get more info here
what worked for me was
I change my Gradle dependencies from 3.5.1 to 4.0.1
dependencies {
classpath 'com.android.tools.build:gradle:4.0.1'
}
which is under build.gradle
The minimum Gradle support for Gradle dependencies(gradle:4.0.1) is gradle-6.1.1
if your gradle version for the project is below that you will have to change it by downloading a higher version or if you have it and you're using a wrapper, you will have to change the distribution to the one higher or same as the 6.1.1 version.
which is under >gradle >wrapple >gradle-wrapple.properties
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-6.7-all.zip
You might most likely need to add to your NDK
for Gradle-6.7 the supported NDK is NDK(side by side) version 21.0.6113669
which is under >tools >sdk manager(android SDK) >sdk tools >ndk side by side
click show package details click and download the appropriate one for you
I clean all SDK folders in c:\Users\User\AppData\Local\Android\Sdk\ndk\
Recent AppCenter android dependencies changes caused my android builds to fail with this error:
No toolchains found in the NDK toolchains folder for ABI with prefix: arm-linux-androideabi
Our solution was to upgrade the gradle version from 3.5.4 to 4.0.1 in the root build.gradle file:
dependencies {
classpath 'com.android.tools.build:gradle:4.0.1'
Additional answer for #gwang and #TillyJonesy:
When running Gradle command with --info(AGP 3.5.4 for me), you will see that when no NDK version was given, AGP will try to use the highest NDK version.
And from the docs of Android NDK guidance, AGP <= 3.5 has no default NDK version.
See: https://developer.android.com/studio/projects/install-ndk#default-ndk-per-agp
Solution for native android developers
Go to File->Settings->Appearance & Behaviour->System Settings->Android SDK-> then select SDK Tools and check 'Show Package Details' from bottom.
in Dropdown of NDK(Side by Side) ,check 22.1.7171670 and uncheck remaining then apply and click ok.
I create new app in flutter and it's work when I run it, but when I add shared_preferences package, I got this error when I run it

I have faced the same problem and i have fixed this with running following command:
flutter pub cache repair
If this is not working then please try the following:
flutter channel stable then run the commands
flutter clean and flutter upgrade
This worked for me
NOTE:- CLOSE THE FLUTTER PROJECT
Go to Flutter sdk path
Enable the view hidden files in Mac by using CTRL + SHIFT + .
Go to .pub-cache
Go to hosted
Go to pub.dartlang.org
delete this folder url_launcher_macos
Open the project and run app
I create a new flutter project in android studio then "open project" the android part of it, I met
an error in MainActivity.kt however it builds successfully.
My class pathes are:
and finally my dependencies are:
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.3.70"
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.2.0'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
I would be grateful if someone could help me.
I face same Problem, now it solved in my case
Step 1 : open your project in AndroidStudio
Step 2 : open Terminal and goto your project path in terminal
Step 3 : Hit this command 'git clean -xfd'
Step 3 : Goto : File -> Invalidate caches/restart
You need to go to the flutter directory
rm -rf bin/cache/artifacts/engine/android*
Then go to project directory
flutter clean
flutter pub get
Also you can "Invalidate caches and restart" in Android Studio.
I had the same issue and was trying to debug for ages. The simple solution was to go to " File > Invalidate Caches/ Restart ".
You need to enable the beta feature "Enable code completion, navigation, etc. for Java / Kotlin" at: Preferences -> Languages & Frameworks -> Flutter (bottom).
Downgrade from Android Studio's Kotlin plugin from 1.3.70 to 1.3.61 solved the problem for me
As it seems it has some problems with androidx libraries! I backed from androidx and it works without error in kotlin and java both.
