Getting "Failed to transform libs.jar to match attributes" error when building a release APK

Question

I am getting an error stating that it "Failed to transform libs.jar to match attributes" because "Transform's input file does not exist". This happened while building a release APK in Flutter.

How do I fix this?

You are building a fat APK that includes binaries for android-arm, android-arm64, android-x64.
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,android-x64
        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,android-x64 --split-per-abi

Answer 1

I have upgraded my gradle build tools 3.5.0 -> 4.0.1. After that I was not able to make release apk. Looks like upgrading gradle build tools broke some lints.

Below solution worked for me

Go in android folder->app->open build.gradle fine Search for lintOptions and add checkReleaseBuilds false example:

lintOptions {
        disable 'InvalidPackage'
        checkReleaseBuilds false //Insert this line
    }
} 

Answer 2

Step 1. flutter build apk --debug

Step 2. flutter build apk --profile

Step 3. flutter build apk --release
