How do I add a version number to my APK files using 0.14+ versions of the Android Gradle plugin?

Question

I want to have the versionName included in the name of the output APK files from my Android build.

There\'s an another answer that works with pre-0.14.x

Answer 1

I copied your answer with some modification:

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

the word "-assistant" is in my filename before the variant name. Example I have 3 variants

ax, bx, cx

The filenames were in my example:

• the-assistant-ax-debug.apk
• the-assistant-bx-debug.apk
• the-assistant-cx-debug.apk

I wanted the version number in there before the variant name. So, after the above they are now called

• the-assistant-1.0-ax-debug.apk
• the-assistant-1.0-bx-debug.apk
• the-assistant-1.0-cx-debug.apk

So, gradle build is adding the variant name in the filename for us.

The ${versionName} is simply "1.0". And I noticed that whether it is ${versionName} or ${variant.versionName}, both produced the same result.

That is to say, if had defaultConfig { versionName "a.b" } and productFlavors { ax { versionName "1.0" } }, the $versionName or $variant.versionName in the loop in this above code will contain the variant version name "1.0"

Hope this helps someoen.

Answer 2

When using version 3.0.0 of the plugin or higher, you have to make a slight change:

applicationVariants.all { variant ->
    variant.outputs.all { output ->
        outputFileName = "myapp-${variant.versionName}-${variant.name}.apk"
    }
}

The 3.0.0 plugin migration documentation says:

If you use each() to iterate through the variant objects, you need to start using all(). That's because each() iterates through only the objects that already exist during configuration time- but those object don't exist at configuration time with the new model. However, all() adapts to the new model by picking up object as they are added during execution.

You need one more loop now that each variant can have multiple outputs:

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