Change apk name with Gradle

Question

I have an Android project which uses Gradle for build process. Now I want to add two extra build types staging and production, so my build.gradle contains:

android {
    buildTypes {
        release {
            runProguard false
            proguardFile getDefaultProguardFile('proguard-android.txt')
        }

        staging {
            signingConfig signingConfigs.staging

            applicationVariants.all { variant ->
                appendVersionNameVersionCode(variant, defaultConfig)
            }
        }

        production {
            signingConfig signingConfigs.production
        }
    }
}

and my appndVersionNameVersionCode looks like:

def appendVersionNameVersionCode(variant, defaultConfig) {
    if(variant.zipAlign) {
        def file = variant.outputFile
        def fileName = file.name.replace(".apk", "-" + defaultConfig.versionName + "-" + defaultConfig.versionCode + ".apk")
        variant.outputFile = new File(file.parent, fileName)
    }

    def file = variant.packageApplication.outputFile
    def fileName = file.name.replace(".apk", "-" + defaultConfig.versionName + "-" + defaultConfig.versionCode + ".apk")
    variant.packageApplication.outputFile = new File(file.parent, fileName)
}

If I execute task assembleStaging then I get proper name of my apk, but when I execute assembleProduction then I get changed names of my apk (like in staging case). For example:

MyApp-defaultFlavor-production-9.9.9-999.apk
MyApp-defaultFlavor-production-9.9.9-999.apk

It looks like in production build type is executed appendVersionNameVersionCode. How can I avoid it?

Answer 1

As CommonsWare wrote in his comment, you should call appendVersionNameVersionCode only for staging variants. You can easily do that, just slightly modify your appendVersionNameVersionCode method, for example:

def appendVersionNameVersionCode(variant, defaultConfig) {
    //check if staging variant
    if(variant.name == android.buildTypes.staging.name){
        if(variant.zipAlign) {
            def file = variant.outputFile
            def fileName = file.name.replace(".apk", "-" + defaultConfig.versionName + "-" + defaultConfig.versionCode + ".apk")
            variant.outputFile = new File(file.parent, fileName)
        }

    def file = variant.packageApplication.outputFile
    def fileName = file.name.replace(".apk", "-" + defaultConfig.versionName + "-" + defaultConfig.versionCode + ".apk")
    variant.packageApplication.outputFile = new File(file.parent, fileName)
    }
}

Lecho's solution doesn't work for Android Gradle Plugin 0.14.3+ because of removal of deprecated APIS: http://tools.android.com/tech-docs/new-build-system

Almost 1.0: removed deprecated properties/methods

...

• Variant.packageApplication/zipAlign/createZipAlignTask/outputFile/processResources/processManifest (use the variant output)

The following works for me:

def appendVersionNameVersionCode(variant, defaultConfig) {
    variant.outputs.each { output ->
        if (output.zipAlign) {
            def file = output.outputFile
            def fileName = file.name.replace(".apk", "-" + defaultConfig.versionName + "-" + defaultConfig.versionCode + ".apk")
            output.outputFile = new File(file.parent, fileName)
        }

        def file = output.packageApplication.outputFile
        def fileName = file.name.replace(".apk", "-" + defaultConfig.versionName + "-" + defaultConfig.versionCode + ".apk")
        output.packageApplication.outputFile = new File(file.parent, fileName)
    }
}

I have use little generic version of it. build and install fine. for example your projectName is "Salad" then for staging apk name will be "Salad-staging-dd-MM-YY" you can also change for debug and release apk. hope my solution will be better.
Change in projectName/app/build.gradle

buildTypes {

debug{

}

staging{
 debuggable true
 signingConfig signingConfigs.debug
 applicationVariants.all { variant ->
 variant.outputs.each { output ->
 def date = new Date();
 def formattedDate = date.format('dd-MM-yyyy')
 def appName = getProjectDir().getParentFile().name
 output.outputFile = new File(output.outputFile.parent,
                                output.outputFile.name.replace(getProjectDir().name +"-staging", "$appName-staging-" + formattedDate)
                                //for Debug use output.outputFile = new File(output.outputFile.parent,
                                //                             output.outputFile.name.replace("-debug", "-" + formattedDate)
                        )
  }
 }
}

release {
  minifyEnabled false
 proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}

Here is what I have done:

 def appName
        if (project.hasProperty("applicationName")) {
            appName = applicationName
        } else {
            appName = parent.name
        }
        applicationVariants.all { variant ->
            variant.outputs.each { output ->
                output.outputFile = new File(output.outputFile.parent, output.outputFile.name.replace("app-release.apk", appName + "_V" + versionCode + ".apk"))
            }
        }
