What about auto build ?

[Uneo7]

If you have no time to publish the app. What about using Travis-CI (Free for open source projects) to auto build and publish on the play store.
It will save you a lot of time, you'd only have to merge changes and pull-request on master to trigger a build and publish (or trigger it manually).

Good suggestion, because the development has stalled on this Repo i created a fork and will continue developing the app. I will implement this later.

Cool ;)

According to me, you already have this working? @Uneo7

@klaasnicolaas not with gapps. I have similar projects working with auto deployment like this.
