Automating application publishing to Google Play using Jenkins

For this we need





  1. A valid Google Play Developer account





  2. Linux server with Docker preinstalled, in my case it's Ubuntu 16.04





  3. Installed Android SDK





  4. Jenkins - in this case, we'll deploy it using Docker





  5. Gitea - A convenient service for our own Git repository (it is not necessary to use GItHub as well), we will also raise it on the basis of a Docker container





Setting up Google Play Account

Let's assume that you are already an existing developer and have published your applications in manual mode, which suggests that you know the main points of the process and should not be voiced, we will only touch on what we need for automatic deployment





  1. Log in to Google Cloud Platform, if the project has not yet been created, then create it





  2. In the IAM and administration section - Service accounts, click Create a service account





  3. After filling in the appropriate fields, it will be created and will appear in the list, click on the three dots on the right and select create a key, select JSON, save it, we will need it to configure Jenkins





  4. Log in to the Gooogle Play Developer Console





  5. email , ( )

Conclusion

In case of a positive feedback from the article, in the next part I will tell you how to write a Telegram bot to notify your testers about the availability of an application update on Google Play.





I hope this information was useful and will somehow make your life easier for setting up automatic publishing.
