Migration from Travis to Drone
This project migrated from GitHub to GitLab, so using Travis for CI isn't a good choice anymore. CI is now done with Drone on my own server.
In this branch I did a lot of things that were required to get it working and deployed on the Play Store again:
- Update Grade
- Update Android SDK
- Update the target SDK version
- Adapting the build process configuration to Drone
- Updated the version code and number generation
