Android Studio – How to resolve "Exception: Gradle task assembleDebug failed with exit code 1"?

Flutter Version: 2.6.0-12.0.pre.381

Dart Version: 2.15.0

Gradle version : distributionUrl=https://services.gradle.org/distributions/gradle-6.7-all.zip

In pubspec.yaml, I have these packages:

environment:
  sdk: ">=2.12.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter
  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  splashscreen: ^1.2.0
  bottom_navy_bar:
  cupertino_icons: ^1.0.2
  image_picker: ^0.8.0+4
  fluttertoast: ^8.0.7
  shared_preferences: ^2.0.6
  share: ^2.0.4
  flutter_barcode_scanner: ^2.0.0-nullsafety.0
  dropdown_search: ^1.0.0
  syncfusion_flutter_pdfviewer:
  ndialog: ^4.1.0
  flutter_pdfview: ^1.0.4
  http: ^0.13.3
  dio: ^4.0.0
  path_provider: ^2.0.3
  downloads_path_provider_28: ^0.1.2
  permission_handler: ^8.1.4+2
  open_file: ^3.2.1
  flutter_local_notifications: ^9.0.0

Same packages are working in another project.
Any suggestions on how to fix the problem. I think it is due to some error in build.graddle.

I have changed minSdkVersion and targetSdkVersion in build.gradle as follows:

        minSdkVersion 23
        targetSdkVersion 29
        multiDexEnabled true

It is showing error while running the project:

Launching libmain.dart on SM M205F in debug mode...

    I changed permission_handler: ^8.1.4+2 with permission_handler: 6.0.0 in pubspec.yaml .Now project is working fine. Thanks for your assistance.

    I think that Build.VERSION_CODES.R is API Level 30 , so setting compileSdkVersion to 30 should fix the issue .

    This is happing due to compileSdkVersion. Head over to android/app/build.gradle and change complieSdkVersion to 31.

    android {
    compileSdkVersion 31
    ...
}

    In pubspec.yaml file :-

    dependencies:
  permission_handler: ^8.2.5

    The error must be happening in versions 8.2.0 and onwards. If you still encounter some error then install a version less 8.2.0.

    Faced the same issue and this is how i solved it:

    First i removed permission_handler from my yaml file.

    Then did a flutter clean.
    Clean Cache

    In pubspec.yaml : I changed the version of the permission_handler plugin from 8.2.6 to:

    permission_handler: ^8.2.0

    permission_handler

    Then In android/app/build.grale file:changed compile sdk version to 31.
