        applicationVariants.all { variant ->
            variant.outputs.each { output ->
                def date = new Date();
                def formattedDate = date.format('yyyyMMddHHmmss')
                output.outputFile = new File(output.outputFile.parent,

//for Debug use output.outputFile = new File(output.outputFile.parent,

                )
            }

Answer 1

Use below code and put it at outside of the android{ } closure:

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
    }
}

Your final apk name will be something like app_1.0.0.apk, if you want to make the name be more fancy, you can modify below line per your requirement.

def apkFileName = "${rootProject.name}_${android.defaultConfig.versionName}.apk"
