How to fix “Gradle build failed to produce an Android bundle package.” in Flutter

问题

On running flutter build appbundle I am getting the following error: Gradle build failed to produce an Android bundle package.

When running in verbose mode this is what I additionally get:

I am on Flutter stable channel v1.2.1.

I can build an apk without a problem though. I can also build an appbundle from another Flutter project.

Based on the error messages above how would you start to find the issue? What might be the problem here?

回答1:

I have similar issue with the same error messages. (Build Release APK successfully but failed to build app bundle) The solution that works for me is to upgrade the Android Gradle Version. Below are the config that works for me (You may upgrade to the latest version also):

1. /android/gradle/wrapper/gradle-wrapper.properties:

distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.2-all.zip

2. /android/build.gradle:

   buildscript {
       repositories {
          google()
          jcenter()
         }
   
       dependencies {
          classpath 'com.android.tools.build:gradle:3.2.1'
       }
   }
   

回答2:

I commented list of APIs in app.gradle and then it works:

android {
    splits {

        abi {

            //include "x86", "x86_64", "armeabi", "armeabi-v7a", "arm64-v8a"

        }
    }
  }

There is a multitude of reasons for which you might encounter a frustrating problem like Gradle build failed to produce an Android bundle package.

As of @Tam Tam Tam's answer, first try to update your gradle and android gradle plugin to a latest version.

If that does not fix your problem, then try to disable all the different architectures and set universalApk to false in your android/app/build.grade in splits section. Put something like this:

splits {
        abi {
            enable true
            reset()
            // include 'x86', 'armeabi-v7a', 'x86_64'
            universalApk false
        }
    }

This suggestion was provided here: https://github.com/flutter/flutter/issues/27462#issuecomment-507229131

It happens because gradle generates the apk following a convention, eg, app-<architecture-name>.apk, which is not understandable by flutter, it expects apk names in another format, eg, simply app.apk. Disabling all different architectures name bring them to a common understanding :)

If that is also not work, then try to remember if you change your package name com.example.packagename to something your own personal like com.mywebsite.packagename. If you have done it, then you probably changed it everywhere needed, for example, in build.gradles and AndroidManifest.xml but you might forgot to change it in your java (or kotlin class).

To make your new package name works, you also have to change the package name in src/main/java/com/mywebsite/packagename/MainActivity.java (in case of kotlin, it's src/main/kotlin/com/mywebsite/packagename/MainActivity.kt)

I hope this helps.

For me, migrating to AndroidX fixed everything:

回答5:

For me, I had signingConfig signingConfigs.debug line missing in my release config of app's build.gradle file. But error I was getting is the same "Gradle build failed to produce an Android bundle package".

android {
    ...
    buildTypes {
        release {
            signingConfig signingConfigs.debug
            ...
        }
    }
}

For me changing my gradle version as following line solved the issue. (I was using a higher version)

android/build.gradle

  dependencies {
     classpath 'com.android.tools.build:gradle:3.3.0'
  }

Here is my senario:

I'm using a remote machine from CI to sign apk with release sign config. So I removed buildTypes.release.signConfig in build.gradle like this:

    buildTypes {
        release {
            // signingConfig signingConfigs.release
            minifyEnabled true
            useProguard true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

This makes the name of the output apk change to app-release-unsigned.apk but flutter expects app-release.apk, which leads to Gradle build failed to produce an Android bundle package.

After adding signingConfig signingConfigs.release back the problem was solved.
