Automatic publish Beta Android app to the Google Play store

Edit

The plugin below no longer works because Google shut down old versions of their API. Consider using Gradle Play Publisher instead.

Update: The plugin is now available as com.savillians.gradle:android-publisher:0.4 from maven central. Add it to your buildscripts definition in build.gradle and apply it as I stated below.

I had the exact same question, and thanks to @edovino's comment and the Google Play API samples, I was able to create a gradle plugin that does the publishing to any track you wish for any flavor/variant you wish.

See the sources here: https://github.com/bluesliverx/gradle-android-publisher

I'm working on publishing this to maven central so it can be used in a build script, but for now you can grab the android-publisher subdirectory in the repo, put it in the root of your gradle build, and rename the folder to buildSrc. Use the following line in the build.gradle file for the android project you want to publish:

apply plugin: com.savillians.gradle.androidpublisher.AndroidPublisherPlugin

You can then set your publishing settings using an androidPublisher block in the build.gradle file.

android {    ...}androidPublisher {    applicationName = "Company-Name-Product-Name/1.0"    packageName = "<package name>"    serviceAccountEmail = "<service account email>"    serviceAccountKeyFile = file('<p12 keyfile - NOT the json file>')    track = "alpha" // default, don't need to specify    variantName = "release" // default, don't need to specify}

Make sure the service account you create has "release manager" permissions, download the p12 key file and put it in the project's directory. Then run this command:

gradle androidPublish

That will send it to Google Play using the credentials you specified. Good luck and let me know if you have questions since this is brand new.

If you're using Jenkins, the Google Play Android Publisher Plugin lets you automatically upload alpha or beta builds.

You can also use it to "promote" an APK from alpha, to beta, or from beta to a staged rollout, for example.

Multiple APK support and the ability to upload (or reuse) expansion files are included as well.

By integrating with the credentials functionality in Jenkins, the plugin can securely access your Google Play account(s) without having to check the private key in to the repository or similar.

There is now a straight forward CLI tool you can call in a build server build step:

It uses google publisher API and uses the new JSON key format.
