This is an example of a simple android application which uses different ways to specify build's versionCode.

In particular, the version code is the incremented latest build number fetched from Google Play Developer API throught google-play Codemagic CLI Tool.

Pass build number with gradlew argument properties

The latest Google Play build number is obtained in codemagic.yaml

LATEST_GOOGLE_PLAY_BUILD_NUMBER=$(google-play get-latest-build-number --package-name 'io.codemagic.androidhelloworldapp')

Increment it and save to a variable (arbitrary name) if it's not empty.

LATEST_GOOGLE_PLAY_BUILD_NUMBER=$(google-play get-latest-build-number --package-name 'io.codemagic.androidhelloworldapp')
if [ -z LATEST_BUILD_NUMBER ]; then
    # fallback in case no build number was found from google play. Alternatively, you can `exit 1` to fail the build
    UPDATED_BUILD_NUMBER=$BUILD_NUMBER
else
    UPDATED_BUILD_NUMBER=$(($LATEST_GOOGLE_PLAY_BUILD_NUMBER + 1))
fi

Provide the created variable as gradlew argument properties for version code and version name:

./gradlew bundleRelease -PversionCode=$UPDATED_BUILD_NUMBER -PversionName=1.0.$UPDATED_BUILD_NUMBER

In build.gradle, the version code and name are read inside a function from the passed arguments

def getMyVersionCode = { ->
    return project.hasProperty('versionCode') ? versionCode.toInteger() : -1
}

def getMyVersionName = { ->
    return project.hasProperty('versionName') ? versionName : "1.0"
}

and used inside the android config

android {
    ...
    defaultConfig {
        ...
        versionCode getMyVersionCode()
        versionName getMyVersionName()
