We love pull requests. Here's a quick guide.
Fork, then clone the repo:
git clone https://github.com/your-user-name/droidplanner.git
Make your change. Compile and test the results (help?):
./gradlew
Push to your fork and submit a pull request.
We have an automated CI server running, which will try to compile your PR. Having that build sucessfuly complete is a good sign.
Now you just need to get some reply from us. We like to review PRs, and make comments if something needs to be changed to match our project syle.
For further commits you might want to consider using a branching model as described in: https://guides.github.com/introduction/flow/
