Closed 1 year ago.
Looks like Bintray library is down and I am not able to build my app. I tried a lot of solutions but none them worked.
A similar github issue is there which is already closed without any proper help.
Github link: https://github.com/flutter/flutter/issues/94400
This is the error I am getting :
Launching lib\main.dart on sdk gphone x86 arm in debug mode...
Running Gradle task 'assembleDebug'...
FAILURE: Build failed with an exception.
What went wrong:
Execution failed for task ':app:checkDebugAarMetadata'.
Could not resolve all files for configuration ':app:debugRuntimeClasspath'.
Could not resolve com.google.android.gms:play-services-location:16.+.

All my codes were right, the only problem was the location package which I replaced with geolocator package. Now it's working fine.

Only change!!

I am having Kotlin code for Android and Kotlin version is
ext.kotlin_version = '1.5.20'
I have this in my dependencies :
classpath 'com.android.tools.build:gradle:4.2.1'
I get an error when running flutter run --release, but flutter run works fine.
Exception: Unsupported Android Plugin version: 4.2.1.
I have tried other Answers from SO like updating the JVM version for Kotlin target VM (I set it to 11 from 8) .
I also have distributionUrl=https\://services.gradle.org/distributions/gradle-6.7.1-all.zip in gradle-wrapper.properties.
Any help is greatly appreciated.

See whether there is something like below in your app build.gradle (app/src/build.gradle)
productFlavors {
app_dev {
dimension "version"
applicationIdSuffix ".dev"
}
app_stg {
signingConfig signingConfigs.debug
dimension "version"
applicationIdSuffix ".stg"
}
app_prod {
signingConfig signingConfigs.release
dimension "version"
}
}
If it does have something like that, then you need to go to
Run -> Edit Configuration -> Pick your main.dart on left side -> Inside 'Build flavor' put "app_dev" inside the textbox (The string can be anything and it depends on what's inside your productFlavors { ... })
This helped me solve my issue.

I had a similar problem when building with flutter build apk --flavor my_flavor.
I had configured ABI splits in my app build.gradle, and removing them solved the issue since they weren't necessary in my case.

I have tried many things but nothing has worked so far:
flutter clean, deleted pubspec.lock and flutter pub cache repair to get rid of cache and reinstall packages but no luck :(
Flutter downgrade, got the same error
Fresh reinstall of flutter, same thing
Fresh git clone of the project and tried running from the prod branch but, nope.
Tried putting org.gradle.parallel=false in gradle settings. No luck :(
I hadn't faced such issues before. In the rare case, flutter clean used to do the trick. Any ideas?

This thing worked for me!.
distributionUrl=https://services.gradle.org/distributions/gradle-6.7-all.zip

Flutter:gradle build failed with error "A problem occurred evaluating root project 'android' > A problem occurred configuring project ':app'."

My flutter app runs fine on the emulator, runs fine on my android when connected via USB, but crashes before opening when updated from the play store. Does the same to everyone else that has tried the update. So I thought I would try rebuilding as apk and install from firebase distribution.
flutter build works fine if i run as appbundle, or apk but only fails on apk --split-per-abi.
I am not sure if this error has to do with why it's crashing or if it's a new problem.
Here is the error I get when running flutter build -v apk --split-per-abi

I seem to keep running into other issues related to this being caused by the gradle version or maybe google services version. I've tried several different versions. Currently using https://services.gradle.org/distributions/gradle-6.5-all.zip and
classpath 'com.android.tools.build:gradle:4.1.0'
classpath 'com.google.gms:google-services:4.1.0'
I also checked the file in the error message, line 646 contains:
abiVersionCode * 1000 + variant.versionCode
I've run flutter clean and here is my flutter doctor -v output:

Change the version of gradle on android/build.gradle file to 3.5.0.
buildscript {
repositories {
google()
jcenter()
}
dependencies {
...
classpath 'com.android.tools.build:gradle:3.5.0' // Use this version
}
}
On android/gradle/wrapper/gradle-wrapper.properties, your distributionUrl should also have the following gradle version.
gradle-5.6.2-all.zip
so that you won't run into any other issues.
Finally, run these commands
rm -rf android/.gradle
rm -rf $HOME/.gradle # This is for Mac users
flutter build apk --target-platform android-arm,android-arm64,android-x64 --split-per-abi
It should work like a charm! And update Gradle later on when things get little matured and stable.

android {
compileSdkVersion 30
lintOptions {
disable 'InvalidPackage'
}
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.example.test_flutter"
minSdkVersion 21
targetSdkVersion 31
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
// TODO: Add your own signing config for the release build.
// Signing with the debug keys for now, so `flutter run --release` works.
}
}
}

PS:
and i had another issue a while back so i changed flutter.gradle file like this
buildscript {
repositories {
google()
jcenter()
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.5.0'
}

It seems your Gradle files are damaged.
Here's what you need to do:
open $HOME/.gradle/wrapper/dists and delete gralde-xxx-all . then execute command: flutter run again.
More info here.

Go into your Project folder and in the
gradle
wrapper
gradle-wrapper
change the number from:
distributionUrl=https\://services.gradle.org/distributions/gradle-6.3-all.zip

I'm gonna say exactly how I overcome this issue .some steps might not be necessary but i did all of this :
unistall flutter and android studio
install the lastest version of both (android studio and flutter )
then add
maven {
url 'http://download.flutter.io'
}
in your build.gradle file
then change compile and target sdk version to 29 (just find them and replace 29 with 28 )
C:\Users\$USER\AndroidStudioProjects\$projectname\android\app\build.gradle
like this
compileSdkVersion 29
targetSdkVersion 29
this is how it got solved for me . i hope it works for you guys too .
