How to customize the APK file name for product flavors?

Try to put this in your android closure of build.gradle

buildTypes {    debug {        // debug buildType specific stuff    }    release {        // release buildType specific stuff    }    applicationVariants.all { variant ->        if (variant.buildType.name.equals("release") &&            variant.productFlavors[0].name.equals("green") &&            variant.zipAlign) {                def apk = variant.outputFile;                variant.outputFile = new File(apk.parentFile, "green.apk");        } else if(variant.buildType.name.equals("release") &&            variant.productFlavors[0].name.equals("blue") &&            variant.zipAlign) {                def apk = variant.outputFile;                variant.outputFile = new File(apk.parentFile, "blue.apk");        }    }}

Now the outputs should be like green.apk and blue.apk.

android {    //........flavorDimensions "version"productFlavors {    Free {        dimension "version"        applicationId "com.exampleFree.app"    }    Paid {        dimension "version"        applicationId "com.examplePaid.app"    }}applicationVariants.all { variant ->    variant.outputs.all { output ->        def appId = variant.applicationId// com.exampleFree.app OR com.examplePaid.app        def versionName = variant.versionName        def versionCode = variant.versionCode // e.g 1.0        def flavorName = variant.flavorName // e. g. Free        def buildType = variant.buildType.name // e. g. debug        def variantName = variant.name // e. g. FreeDebug        //customize your app name by using variables        outputFileName = "${variantName}.apk"    }}}

Apk name FreeDebug.apk

Proof

For Android Gradle Plugin 0.13.+ you should use something like this:

android{    buildTypes {        applicationVariants.all { variant ->            variant.outputs.each { output ->                def apk = output.outputFile;                def newName = "mysms-" + variant.baseName.replace("-release", "") + "-" + defaultConfig.versionName + ".apk";                output.outputFile = new File(apk.parentFile, newName);            }        }    }}
