android studio 3.1: build:gradle:3.1.0 - Absolute path are not supported when setting an output file name

Question

When I use Android Studio 3.0 and I use the next version of Android Gradle Plugin in project/build.gradle:

cl         


        

Answer 1

The simplest solution for Android Gradle plugin 3.4.0+ is as below:

Assemble/concatenate your new file name:

def newFileName = "assemble-your-new-file-name"

Then, simply assign it back.

outputFileName = newFileName

More specifically is as following

android.applicationVariants.all { variant ->
    variant.outputs.each { output ->
        // Redirect your apks to new defined location to outputDirPath
        def outputDirPath = new File("${project.rootDir.absolutePath}/apks/${variant.flavorName}/${variant.buildType.name}")
        variant.packageApplicationProvider.get().outputDirectory = outputDirPath

        def apkFileName = "${rootProject.name}_${android.defaultConfig.versionName}.apk"
        output.outputFileName = apkFileName // directly assign the new name back to outputFileName
    }
}
