Upload signed applications to Google Play with a single command

This sbt plugin relies on sbt-android to package and sign an apk file to then publish the app via the Google Play Developer API.

addSbtPlugin( "io.taig" % "sbt-googleplay" % "1.1.1" )

In order to authenticate with the Google Play Developer API, you have to create a service account in the Google Play Developer Console and obtain a P12 service account key.

Please note that the permission system for service accounts does not work as expected, so you have to at least grant the following permissions:

• Edit store listing, pricing & distribution
• Manage Production APKs
• Manage Alpha & Beta APKs
• Manage Alpha & Beta users

lazy val app = project( ... )
    .enablePlugins( GooglePlayPlugin )
    .settings(
        googlePlayTrack := "alpha",
        googlePlayServiceAccountEmail := System.getenv( "GOOGLE_PLAY_SERVICE_ACCOUNT_EMAIL" ),
        googlePlayServiceAccountKey := file( System.getenv( "GOOGLE_PLAY_SERVICE_ACCOUNT_KEY" ) )
    )

When properly configured it is now possible to build, package and publish the app with a single command:

sbt googlePlayPublish

As of version 1.1.1, it is also possible to simply publish an existing apk file:

sbt googlePlayPublishFile ./path/to/my/app.apk

myPublishingTask := {
    val apk: File = ???
    googlePlayPublishApk.value( apk )
}

It is optionally possible to submit a changelog via the googlePlayChangelog task while publishing the apk.

googlePlayChangelog := Map(
    "en-US" -> "Fixed all the bugs"
)

Keep in mind to not exceed the 500 character limit
