[FIXED] How to Rename and Generate all APK & Bundle from Gradle with Product flavour and APK Splits

Issue

As I have tried these 2 ways (using a single at a time) to rename the APK

Option - One

// To Change the APK and Bundle Name
archivesBaseName = "${name}-v${versionCode}_${versionName}-${new Date().format('ddMMMyyyy_HH-mm')}"

Option - Two

(for this also tried to change the - variant.outputs.all to variant.outputs.each)

android.applicationVariants.all { variant ->
    variant.outputs.all { output ->
        output.outputFileName = "${variant.buildType.name}-v${versionCode}_${versionName}-${new Date().format('ddMMMyyyy_HH-mm')}.apk"
    }
}

---

When I use option One,

Issue - it generates all splits but it overrides the flavor config with the last flavor written in Gradle.

Also, try to put option One only once in defaultConfig but as productFlavours written after that it returns the null value in versionCode and versionName.

productFlavors {
    aFlavor {
        applicationId "com.a"
        
        versionCode 5
        versionName "1.0.5"

        signingConfig signingConfigs.signingA

        // To Change the APK and Bundle Name
        archivesBaseName = "${name}-v${versionCode}_${versionName}-${new Date().format('ddMMMyyyy_HH-mm')}"
    }
    bFlavor {
        applicationId "com.b"

        versionCode 5
        versionName "1.0.5"

        signingConfig signingConfigs.signingB

        // To Change the APK and Bundle Name
        archivesBaseName = "${name}-v${versionCode}_${versionName}-${new Date().format('ddMMMyyyy_HH-mm')}"
    }
    cFlavor {
        applicationId "com.c"

        versionCode 3
        versionName "1.0.3"

        signingConfig signingConfigs.signingC

        // To Change the APK and Bundle Name
        archivesBaseName = "${name}-v${versionCode}_${versionName}-${new Date().format('ddMMMyyyy_HH-mm')}"
    }
}

When I use option Two,

Issue - it generates the correct name but generates a single APK file.

splits {
    abi {
        enable true
        reset()
        include 'arm64-v8a', 'x86', 'x86_64'
        universalApk false
    }
}

android.applicationVariants.all { variant ->
    variant.outputs.all { output ->
        output.outputFileName = "${variant.buildType.name}-v${versionCode}_${versionName}-${new Date().format('ddMMMyyyy_HH-mm')}.apk"
    }
}

Issue for bundle - not able to rename the bundle using option Two.

Solution

As per This answer, you can go with Option - Two with minor changes as mention below only works for APK, not the Bundle / AAB files

splits {
    abi {
        enable true
        reset()
        include 'arm64-v8a', 'x86', 'x86_64'
        universalApk false
    }
}

android.applicationVariants.all { variant ->
    variant.outputs.all { output ->
        // New one or Updated one
        output.outputFileName = "${variant.getFlavorName()}-${variant.buildType.name}-v${versionCode}_${versionName}-${new Date().format('ddMMMyyyy_HH-mm')}-${output.getFilter(com.android.build.OutputFile.ABI)}.apk"
        // Old one
        // output.outputFileName = "${variant.buildType.name}-v${versionCode}_${versionName}-${new Date().format('ddMMMyyyy_HH-mm')}.apk"
    }
}

Also, remove the line from each Flavor's block

// To Change the APK and Bundle Name
archivesBaseName = "${name}-v${versionCode}_${versionName}-${new Date().format('ddMMMyyyy_HH-mm')}"

By this, you get the output file name like this

• Release

aFlavor-release-v5_1.0.5-16Jan2020_21-26-arm64-v8a.apk

aFlavor-release-v5_1.0.5-16Jan2020_21-26-x86_64.apk

aFlavor-release-v5_1.0.5-16Jan2020_21-26-x86.apk

• Debug

aFlavor-debug-v5_1.0.5-16Jan2020_21-26-x86_64.apk

aFlavor-debug-v5_1.0.5-16Jan2020_21-26-x86.apk

For bFlavor

Similar name as above just change the prefix aFlavor with bFlavor like

bFlavor-release-v5_1.0.5-16Jan2020_21-26-arm64-v8a.apk

For cFlavor

Similar name as above just change the prefix aFlavor with cFlavor and, versionCode and versionName as respected

cFlavor-release-v3_1.0.3-16Jan2020_21-26-arm64-v8a.apk
