after running command in terminal, Gradle is completed unreasonably quick with a successful build result only for app-armeabi-v7a-release.apk, however, when checking the flutter-apk folder I see that only the files bellow were built and had their time stamp updated
app-debug.apk,
app.apk,
app.apk.sha1
but other files were not changed and still had an old time stamp (two weeks ago)
app-arm64-v8a-release.apk,
app-armeabi-v7a-release.apk,
app-x86_64-release.apk

I use my phone as an emulator while developing applications with Flutter.
After updating to the Flutter 2 version, Web Folder added to Flutter file directory, I know that.
but i can't run the project
Here I started the classic flutter counter app and the result:
Launching lib\main.dart on MI 5 in debug mode...
lib\main.dart:1
Exception: Gradle task assembleDebug failed with exit code -1
Exited (sigterm)
I searched for a solution on the internet but could not solve this stupid error
how can i solve this problem?
Connect to Internet
run flutter clean
then flutter pub get
then flutter run .
This might help, try it out.
This error usually comes when some files are pending download or so.
if I use flutter run command from terminal
Launching lib\main.dart on MI 5 in debug mode...
Running Gradle task 'assembleDebug'...
Running Gradle task 'assembleDebug'... Done 76,3s
Exception: Gradle task assembleDebug failed with exit code -1
I'm not sure but,
Try changing minSdkVersion from 16 to 21
You can find this property in ./android/app/build.gradle
Then do a flutter clean and run the project
If this does not work there might be issue with the emulator or the flutter version.
Please I need Help Solving this Issue
I have been running my flutter app without issues, but recently I can't run or debug my apps again, each time I try running my app from the terminal or debug console it always get stuck at Flutter App stuck at “Running Gradle task 'assembleDebug'”
C:\Development\projects\flutter>cd kchat
C:\Development\projects\flutter\Kchat>flutter run
Running "flutter pub get" in Kchat... 3.6s
Launching lib\main.dart on GIONEE S10C in debug mode...
Running Gradle task 'assembleDebug'...
(This is taking an unexpectedly long time.)
I have solved the problem by running
flutter run -v
it fixed all the problem but took a longer time, and I can now use
flutter run
but still can't use Debug console
Alternatively, try to fix your project.
Delete the android folder in your project, having previously saved it in another place, then in the terminal run flutter create your_project_name for the folder in which your project is located.
FAILURE: Build failed with an exception.
Where:
Script 'C:\src\flutter\packages\flutter_tools\gradle\flutter.gradle' line: 904
What went wrong:
Execution failed for task ':app:compileFlutterBuildDebug'.
Process 'command 'C:\src\flutter\bin\flutter.bat'' finished with non-zero exit value 1
I tried flutter clean / pug get and update but application is still not working.
Try this:
flutter clean
flutter pub get
Once these two commands have been successfully executed, launch your project ... This is what I did and it worked.
try running
flutter clean
flutter upgrade
it work for me.
In Android Studio I did the following:
flutter clean
flutter pub get
Invalidate Caches and Restart (from the File menu)
After all that, I re-ran the flutter build appbundle command and it worked.
My antivirus was blocking dart from reading asset images, i allowed it from there and the error got fixed!!
I've had the same error and tried the following:
uninstall android studio and delete all folders regarding this
clean up registry
review path for environment variables
give all sorts of flutter commands (clean, update, and so on)
Until I realized this is an error on the flutter folder, so basically this is due to some force close some operations and the variables that write in the 'flutter.gradle' file are obsolete. What I did and worked for me:
Make sure you have all android studio processes closed.
Delete the flutter folder (the one that you defined as for the PATH)
Extract in the same location the flutter folder from the SDK archive.
Enjoy :)
Powershell commands Example:
Remove-Item 'D:\DEV\flutter'
Expand-Archive -LiteralPath 'C:\Archives\flutter_windows_1.22.3-stable.Zip' -DestinationPath D:\DEV
francis#homelaptop:~/project/flybird$ flutter build apk
You are building a fat APK that includes binaries for android-arm, android-arm64.
If you are deploying the app to the Play Store, it's recommended to use app bundles or split the APK to reduce the APK size.
To generate an app bundle, run:
flutter build appbundle --target-platform android-arm,android-arm64
Learn more on: https://developer.android.com/guide/app-bundle
To split the APKs per ABI, run:
flutter build apk --target-platform android-arm,android-arm64 --split-per-abi

Please review your Gradle project setup in the android/ folder.
Update your gradle version from project => android => build. For me :
dependencies {
classpath 'com.android.tools.build:gradle:3.4.2'
}
Use latest sdk tool version 28 not 29
Open terminal from Tools >>Flutter and run these following commands
flutter upgrade
flutter doctor
After installing flutter and running my emulator it stops at initializing gradle on android studio and on vs code.
It outputs:
this is taking an unexpectedly long time.
I ran flutter doctor and no issues and also flutter doctor -v and still no issues. I tried flutter upgrade but still no difference.
What is the next thing to try?
flutter error log
It looks like it is just taking forever to start; You can read the thread on the issue on
Github:
To summaries: here is one of the issues: Downloading 400mb of dependencies
Solved Initializing gradle problem
The problem is that when first time we are trying to run our flutter
project it does not have the required flutter gradle file. The
required file size that gradle downloads is about 300-400MB that's why
it takes so much time. Following are the steps:
Run your project by clicking on the 'Run' button or flutter run in the command terminal
Then go to the place where your .gradle file is located (usually it is in the C:\Users). In the .gradle folder there is file
name as wrapper in this there is dists folder. In dists folder there
is gradle folder which is being downloaded.
wait till the gradle file is being downloaded and after sometime your project would compile.
its working thaaaaaanks
I am new to mobile development; Everything takes eternity.
Solved this issue by removing all the gradle files from
C:\Users\.gradle\wrapper\dists
Now when you run your flutter app, it will automatically download the required gradle files.
Enjoy!!!
