How to set versionName in APK filename using gradle?

I only have to change the version name in one place. The code is simple too.

The examples below will create apk files named named MyCompany-MyAppName-1.4.8-debug.apk or MyCompany-MyAppName-1.4.8-release.apk depending on the build variant selected.

Note that this solution works on both APK and App Bundles (.aab files).

#Solution for Recent Gradle Plugin

android {
    compileSdkVersion 22
    buildToolsVersion "22.0.1"
    defaultConfig {
        applicationId "com.company.app"
        minSdkVersion 13
        targetSdkVersion 21
        versionCode 14       // increment with every release
        versionName '1.4.8'   // change with every release
        setProperty("archivesBaseName", "MyCompany-MyAppName-$versionName")
    }
}

The above solution has been tested with the following Android Gradle Plugin Versions:

3.6.4 (August 2020)
3.5.2 (November 2019)
3.3.0 (January 2019)
3.1.0 (March 2018)
3.0.1 (November 2017)
3.0.0 (October 2017)
2.3.2 (May 2017)
2.3.1 (April 2017)
2.3.0 (February 2017)
2.2.3 (December 2016)
2.2.2
2.2.0 (September 2016)
2.1.3 (August 2016)
2.1.2
2.0.0 (April 2016)
1.5.0 (2015/11/12)
1.4.0-beta6 (2015/10/05)
1.3.1 (2015/08/11)

I'll update this post as new versions come out.

#Solution Tested Only on versions 1.1.3-1.3.0 The following solution has been tested with the following Android Gradle Plugin Versions:

1.3.0 (2015/07/30) - Not Working, bug scheduled to be fixed in 1.3.1
1.2.3 (2015/07/21)
1.2.2 (2015/04/28)
1.2.1 (2015/04/27)
1.2.0 (2015/04/26)
1.2.0-beta1 (2015/03/25)
1.1.3 (2015/03/06)

app gradle file:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"
    defaultConfig {
        applicationId "com.company.app"
        minSdkVersion 13
        targetSdkVersion 21
        versionCode 14       // increment with every release
        versionName '1.4.8'   // change with every release
        archivesBaseName = "MyCompany-MyAppName-$versionName"
    }
}

This solved my problem: using applicationVariants.all instead of applicationVariants.each

buildTypes {
      release {
        signingConfig signingConfigs.release
        applicationVariants.all { variant ->
            def file = variant.outputFile
            variant.outputFile = new File(file.parent, file.name.replace(".apk", "-" + defaultConfig.versionName + ".apk")) 
        }
    }       
}

Update:

So it seems this does not work with 0.14+ versions of android studio gradle plugin.

This does the trick (Reference from this question ) :

android {
    applicationVariants.all { variant ->
        variant.outputs.each { output ->
            output.outputFile = new File(
                    output.outputFile.parent,
                    output.outputFile.name.replace(".apk", "-${variant.versionName}.apk"))
        }
    }
}

(EDITED to work with Android Studio 3.0 and Gradle 4)

I was looking for a more complex apk filename renaming option and I wrote this one in the hope it is helpfull for anyone else. It renames the apk with the following data:

flavor
build type
version
date

It took me a bit of research in gradle classes and a bit of copy/paste from other answers. I am using gradle 3.1.3.

In the build.gradle:

android {

    ...

    buildTypes {
        release {
            minifyEnabled true
            ...
        }
        debug {
            minifyEnabled false
        }
    }

    productFlavors {
        prod {
            applicationId "com.feraguiba.myproject"
            versionCode 3
            versionName "1.2.0"
        }
        dev {
            applicationId "com.feraguiba.myproject.dev"
            versionCode 15
            versionName "1.3.6"
        }
    }

    applicationVariants.all { variant ->
        variant.outputs.all { output ->
            def project = "myProject"
            def SEP = "_"
            def flavor = variant.productFlavors[0].name
            def buildType = variant.variantData.variantConfiguration.buildType.name
            def version = variant.versionName
            def date = new Date();
            def formattedDate = date.format('ddMMyy_HHmm')

            def newApkName = project + SEP + flavor + SEP + buildType + SEP + version + SEP + formattedDate + ".apk"

            outputFileName = new File(newApkName)
        }
    }
}

If you compile today (13-10-2016) at 10:47, you get the following file names depending on the flavor and build type you have choosen:

dev debug: myProject_dev_debug_1.3.6_131016_1047.apk
dev release: myProject_dev_release_1.3.6_131016_1047.apk
prod debug: myProject_prod_debug_1.2.0_131016_1047.apk
prod release: myProject_prod_release_1.2.0_131016_1047.apk

Note: the unaligned version apk name is still the default one.

To sum up, for those don't know how to import package in build.gradle(like me), use the following buildTypes,

buildTypes {
      release {
        signingConfig signingConfigs.release
        applicationVariants.all { variant ->
            def file = variant.outputFile
            def manifestParser = new com.android.builder.core.DefaultManifestParser()
            variant.outputFile = new File(file.parent, file.name.replace(".apk", "-" + manifestParser.getVersionName(android.sourceSets.main.manifest.srcFile) + ".apk")) 
        }
    }       
}

===== EDIT =====

If you set your versionCode and versionName in your build.gradle file like this:

defaultConfig {
    minSdkVersion 15
    targetSdkVersion 19
    versionCode 1
    versionName "1.0.0"
}

You should set it like this:

buildTypes {   
        release {
            signingConfig signingConfigs.releaseConfig
            applicationVariants.all { variant ->
                def file = variant.outputFile
                variant.outputFile = new File(file.parent, file.name.replace(".apk", "-" + defaultConfig.versionName + ".apk"))
            }
        }
}

====== EDIT with Android Studio 1.0 ======

If you are using Android Studio 1.0, you will get an error like this:

Error:(78, 0) Could not find property 'outputFile' on com.android.build.gradle.internal.api.ApplicationVariantImpl_Decorated@67e7625f.

You should change the build.Types part to this:

buildTypes {
        release {
            signingConfig signingConfigs.releaseConfig
            applicationVariants.all { variant ->
                variant.outputs.each { output ->
                    output.outputFile = new File(output.outputFile.parent, output.outputFile.name.replace(".apk", "-" + defaultConfig.versionName + ".apk"))
                }
            }
        }
    }

If you don't specify versionName in defaultConfig block then defaultConfig.versionName will result in null

to get versionName from manifest you can write following code in build.gradle:

import com.android.builder.DefaultManifestParser

def manifestParser = new DefaultManifestParser()
println manifestParser.getVersionName(android.sourceSets.main.manifest.srcFile)
