Flutter failed to compile apk: Finished with error: Gradle task assembleDebug failed with exit code 1 - flutter

Question

Flutter failed to compile an apk. I am not sure if this has something to do with AndroidX or something.
Launching lib\main.dart on Android SDK built for x86 in debug mode...
Initializing gradle...
Resolving dependencies...
Running Gradle task 'assembleDebug'...
registerResGeneratingTask is deprecated, use registerGeneratedResFolders(FileCollection)

I ran flutter clean. I also ran flutter run -v. This is what happened: https://1drv.ms/t/s!An3OLJ7n0CjEku1SBrSABWab901z3Q
(I have used an external file locker because the stack trace is too large for the Stack Overflow editor).
This issue is similar to https://github.com/flutter/flutter/issues/30634

Answer 1

try follow steps:1. in gradle-wrapper.properties, downgrade from 5.1.1 to 4.10.2.2. int root/build.gradle, change android gradle version into 'com.android.tools.build:gradle:3.3.2'
Hope it is useful

Answer 2

It is common after migration to androidX.
If you followed recommended route from here:
https://flutter.dev/docs/development/packages-and-plugins/androidx-compatibility
Try this:
Check with steps in "not recommended" way in above tutorial if every listed files is same as in your project, especially :
in root/android/gradle/wrapper/gradle-wrapper.properties set distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.2-all.zip (probably you have version 5.1.1 )
in root/android/build.gradle, set
dependencies {
classpath 'com.android.tools.build:gradle:3.3.2'
}
check if in root/android/app/build.gradle SDK version is set to minimum 28 for:
compileSdkVersion 28 and targetSdkVersion 28
If you still get error then here is what helped me:
delete .gradle and .m2 folders from $HOME directory, as well with in app folders: root/android/.gradle and root/build
flutter doctor
flutter clean
flutter packages pub cache clean
if you changed (as me) app icon then run:
flutter packages pub run flutter_launcher_icons:main
it will render icons for app - without it print same error with gradle..
Invalidate caches in Android Studio "File" > "Invalidate Caches / Restart..."
If nothing from above works open android project as module
(you can do it by opening any file inside android folder for example manifest, then bar above code will shows with link to "Open for Editing in Android Studio", more here https://flutter.dev/docs/development/tools/android-studio )
Then click on gradle tab on the left and compile app - should show now more detailed error message.

Answer 3

Ok so here is your fix, open android sdk settings and uncheck Hide Obsolete Packages and in sdk tools, Check Android SDK Tools (Obsolete) than click ok/apply. It will download old SDK. Than Restart the IDE, Run default flutter program on emulator. This error occurs because flutter isn't compatible with latest Android SDK so you have yo manually install old SDK in Android studio.

Answer 4

Try running "flutter clean" in the project. If it doesn't work, please paste the output after running "flutter run -v".

Answer 5

In the debug mode applications worked well, but when I tried to build a release version, it had this error.
"Flutter doctor -v" was ok.
Made flutter clean.
Checked all AndroidX recommendations, used all latest versions of packages.
Checked android/app/fourpillarsappru1.keystore settings.
Finally the decision was use build in in Android Studio commands instead of command line "flutter build apk".
So, the decision in my case was:
Open build.gradle for editing in Android Studio
Choose Build / Generate Signed Bundle/APK

Answer 6

I had the same problem and solve the error by running flutter doctor --android-licenses and accept all licenses agreement.
I hope it will help

Answer 7

The Solution that works for me and makes the most sense CLEAN CACHE
Enter Command below
--> flutter packages pub cache clean

Answer 8

Downgrading the build gradle version in gradle-wrapper.properties from 5.1.1 to 4.10.2 worked for me.
distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.2-all.zip
Dependencies in project: build.gradle
dependencies {
classpath 'com.android.tools.build:gradle:3.3.2'
classpath 'com.google.gms:google-services:4.0.1'
}
module: build.gradle
def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
localPropertiesFile.withReader('UTF-8') { reader ->
localProperties.load(reader)
}
}
def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}
def versionPropertiesFile = rootProject.file("../version.properties")
def versionProperties = new Properties()
versionProperties.load(new FileInputStream(versionPropertiesFile))
def flutterVersionCode = versionProperties.getProperty('flutter.versionCode')
def flutterVersionName = versionProperties.getProperty('flutter.versionName')
apply plugin: 'com.android.application'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
def keystorePropertiesFile = rootProject.file("key.properties")
def keystoreProperties = new Properties()
keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
android {
compileSdkVersion 28
lintOptions {
disable 'InvalidPackage'
}
defaultConfig {
applicationId "com.lok.sewa"
minSdkVersion 16
targetSdkVersion 28
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
signingConfigs {
release {
keyAlias keystoreProperties['keyAlias']
keyPassword keystoreProperties['keyPassword']
storeFile file(keystoreProperties['storeFile'])
storePassword keystoreProperties['storePassword']
}
}
buildTypes {
release {
// Signing with the debug keys for now, so `flutter run --release` works.
signingConfig signingConfigs.release
}
}
}
flutter {
source '../..'
}
dependencies {
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
}
apply plugin: 'com.google.gms.google-services'

Answer 9

Try checking your key.properties file. There might be error in key path, keyAlias or passwords. The error by key errors is not traceable.
This solution worked for me

Answer 10

It is android problems only so
Open in Android Studio
and pick Flutter->Open module in Android Studio
menu Build->Build Bundle(s) / APKs->Build Bundles.

Answer 11

My code contain keystore info in build.gradle,but we don't have keystore file in our git repository.My colleague uploaded his local keystore file and the problem was solved.

Answer 12

I just simply fixed it by changing the minSdkVersion . Just try minSdkVersion 19 or 21. It will fix.
compileSdkVersion 29
minSdkVersion 19
targetSdkVersion 29
