How to run a Gradle task after apks are produced in Android Studio?

Question

The following task (in build.gradle of an app's module) seems to run always before the apk is produced:

android.applicationVariants.all { variant ->
    if (variant.buildType.name == 'release') {
            def releaseBuildTask = tasks.create(name: "debug") {
            println("....................  test   ..............................")
        }
        releaseBuildTask.mustRunAfter variant.assemble
    }
}

Could anyone offer a tip on how to run a task after the apks are produced?

Answer 1

Android tasks are typically created in the "afterEvaluate" phase. Starting from gradle 2.2, those tasks also include "assembleDebug" and "assembleRelease". To access such tasks, the user will need to use an afterEvaluate closure:

afterEvaluate { assembleDebug.dependsOn someTask }

try add this in you app/build.gradle

assembleDebug.doLast {
    android.applicationVariants.all { variant ->
        if (variant.buildType.name == 'release') {
            def releaseBuildTask = tasks.create(name: "debug") {
                println("....................  test   ..............................")
            }
            releaseBuildTask.mustRunAfter variant.assemble
        }
    }
    println "build finished"
}

invoke the build command and specify the task assembleDebug

./gradlew assembleDebug

I found a solution that works, to copy the release APK into the project root automatically on build completion.

    android {
        ...
        task copyReleaseApk(type: Copy) {
            from 'build/outputs/apk'
            into '..' // Into the project root, one level above the app folder
            include '**/*release.apk'
        }

        afterEvaluate {
            packageRelease.finalizedBy(copyReleaseApk)
        }
}
