Question

Launching lib\main.dart on AOSP on IA Emulator in debug mode... Running Gradle task 'assembleDebug'... Warning: The plugin path_provider_android requires Android SDK version 31. Warning: The plugin shared_preferences_android requires Android SDK version 31. One or more plugins require a higher Android SDK version. Fix this issue by adding the following to D:\App Dev Projects\marvelyprojects\android\app\build.gradle: android { compileSdkVersion 31 ... }

Parameter format not correct -

FAILURE: Build failed with an exception.

• What went wrong: Execution failed for task ':app:checkDebugAarMetadata'.

BUILD FAILED in 11s Exception: Gradle task assembleDebug failed with exit code 1

Answer 1

Following steps fixed the same issue which I was facing on flutter/vscode.

1/..android\app\build.gradle: change 'compileSdkVersion' and 'targetSdkVersion' to 31 (from 30)

2/ above change gave new error ==> ....

build\app\intermediates\packaged_manifests\debug\AndroidManifest.xml:2: AAPT: error: attribute 'package' in tag is not a valid Android package name: 'com.ulusoyapps.sharewhatyouknow.002-navigator2'.

3/ as per https://developer.android.com/guide/topics/manifest/manifest-element.html#package, packagge name was incorrect. I changed it to 'com.ulusoyapps.sharewhatyouknow.a002_navigator2' , "package" ==> build\app\intermediates\packaged_manifests\debug\AndroidManifest.xml "applicationId" ==> android\app\build.gradle

4/ above change gave following error... BUILD FAILED in 11s ?? Flutter Fix ????????????????????????????????????????????????????????????????????????????????????? ?

5/ changed ext.kotlin_version = '1.3.50' in ... android\build.gradle to 1.6.10
