How to generate output APK file with Customised name in Android Studio?

Issue

I want to generate output apk file using customized name. Eg. By default, android studio generates "app-debug.apk" file. But I want it to be - "MyAppName_myCurrentProdFlavour_vMyVersionName.apk" How to do this using build.gradle file of module

Solution

1. For changing app bundle name (.aab file):

in app module's build.gradle:

def dateFormat = new Date().format('ddMMMyy_HHmm')
defaultConfig {
        applicationId "com.xyz"
        minSdk 21
        targetSdk 31
        versionCode 3
        versionName "1.0.2"

        setProperty("archivesBaseName", "yourappname" + "_v" + versionName + "(" + versionCode + ")_"+dateFormat)

    }

For example: if your app name is XYZ then the bundle name will generated with name: XYZ_v1.0.2(3)_28Jan22_1152-prod-release

where, yourappname is XYZ , versionName is 1.0.2 , versionCode is 3 , dateFormat is 28Jan22_1152 , and app flavorType and buildType is prod-release

2. For changing apk file name (.apk file)

in app module's build.gradle:

android {

applicationVariants.all { variant ->
            variant.outputs.each { output ->
                def name = "XYZ"
                def SEP = "_"
                def flavor = variant.productFlavors[0].name
                def buildType = variant.buildType.name
                def versionName = defaultConfig.versionName
                def versionCode = defaultConfig.versionCode
                def newApkName = name + SEP + "v" + versionName + SEP + flavor + SEP + buildType + SEP + "vc" + versionCode + SEP + dateFormat + ".apk"
                output.outputFileName = newApkName
            }
        }    
}

For example, if your app name is XYZ then this will generate APK file with following custom name: XYZ_v1.0.2_prod_release_vc3_28Jan22_1152

Note: You can change dateFormat as per your requirement, for apk name if you don't have productFlavours then remove all related references from the code given above.
