Could not get unknown property 'apkNames' in android gradle plugin 4.1.0

Question

I am using this code in build.gradle:

android {
    applicationVariants.all { variant ->
        variant.packageApplicationProvider.configure { packageApplicationTask ->
            doLast {
                packageApplicationTask.apkNames.each { apkName ->
                    def apkDir = "./build/outputs/apk/${flavorName}/${buildType.name}"
                    def apkDestName = apkName.replace("app-", "stickerly-android-" + variant.versionName + "-").replace(".apk", "-" + getDate() + ".apk")

                    println "#####Rename ${variant.name} Apk File"
                    copy {
                        from("$apkDir/$apkName").into(apkDir).rename { String fileName -> apkDestName }
                    }

                    println "#####Copy mapping File"
                    def mappingDir = "./build/outputs/mapping/${flavorName}${buildType.name.capitalize()}"
                    copy {
                        from("$mappingDir/mapping.txt").into(mappingDir).rename {
                            "mapping-stickerly-${variant.versionName}.txt"
                        }
                    }
                }
            }
        }
    }
}

With this code I rename apk file and copy mapping file. I worked in android gradle plugin 4.0, but it does not work in 4.1 with this message

Where:

Script '/Users/snow/workspace/stickerly-android/app/build-android-extra.gradle' line: 5

What went wrong:

Execution failed for task ':app:packageExternalArm8Debug'. Could not get unknown property 'apkNames' for task ':app:packageExternalArm8Debug' of type com.android.build.gradle.tasks.PackageApplication.

I think API has changed but I can not find any documents. Someone can help me? Thanks.

property apkNames is removed in AGP 4.1

you can try this

gradle.taskGraph.afterTask { Task task, TaskState state ->
    if (!state.failure
            && task.project.name == project.name
            && task.name.startsWith("package")
            && !task.name.endsWith("UnitTest")) {
        def outputDir = task.outputDirectory.getAsFile().get()
        task.variantOutputs.getOrNull()?.each { variant ->
            println "" + outputDir + "/" + variant.outputFileName.get()
        }
    }
}

add this at the end of your build.gradle file.

change println to whatever logic you want.

by the way, if you want to check the properties you may use, just add gradle plugin as a dependency of your project, click Sync in Android Stuido, then you can find it in External Librarys (key map: Command + 1, and switch to project view).

like this

dependencies {
    implementation 'com.android.tools.build:gradle:4.1.0'
}

and these properties and tasks are intentionally invisible in lib com.android.tools.build:gradle-api, modifications in future releases are expected.
