Publish apps to the GooglePlayStore through gradle

This plugin aims to simplify the publishing process for android apps to the google play store.
It's currently still work in progress, but basic functionalities are present.
Contributions are very welcome!

Getting started

Look into Getting started section to get more information.

Quick start

This quick start guide assumes you have already setup a google service account and you've already published an app bundle release to the track you want to upload to. If not, read the Getting started section.

Minimal gradle configuration:
App build.gradle.kts:

plugins {
    id("com.android.application")
    id("ch.hippmann.androidpublisher")
}

androidpublisher {
    credentialsJsonFile = File("path/to/your/service/account/credentials.json")
}

Root build.gradle.kts:

plugins {
    id("ch.hippmann.androidpublisher") version "0.3.3" apply false
}

This requires the appVersionCode to be defined in gradle.properties with the key appVersionCode:

appVersionCode=23

and a releaseNotes.csv file present in the rootProject dir with the following spreadsheet format:

VersionCode	en-gb	de-ch	otherLanguages
1	Some release notes in UTF-8	Some text in german	Other languages text
2	Some release notes in UTF-8	Some text in german	Other languages text

This configuration generates gradleTasks in the group androidpublisher which you can call through CI/CD or locally if you have the signing keys locally that you used for publishing the app on the google play store.
Travis example:

deploy:
  - provider: script
    script: ./gradlew generateVersionCodeForRelease && ./gradlew -DkeyPassword="$SIGNATURE_KEY_PASSWORD" -DstorePassword="$SIGNATURE_STORE_PASSWORD" uploadReleaseToInternalTrack
    on:
      tags: true

(Note the separation of generateVersionCodeForRelease and uploadReleaseToInternalTrack into two separate gradle commands. This is necessary for gradle to pick up the changed versionCode!)

Gradle example:

./gradlew generateVersionCodeForRelease && ./gradlew uploadReleaseToInternalTrack

Known limitations

• Only one versionCode for all app variants supported

These limitations might get addressed in future versions
