Localization files are located in the app/src/main/res/values-* directories.
Start by looking at the open issues to contribute code.
Make sure to write your name and e-mail address in format Name <e-mail> in the license declaration above every file you make changes to.
Repeat and rinse, if you send enough patches to demonstrate you have a good coding skills, you will be given commit access on the real repo, making you part of the development team.
Also, take a look at Coding Guidelines before making code changes.
Make sure that all existing and new tests are passing.
- Keep it snimple snupid: KISS
- No repeating yourself. Re-use your own code and that of others.
- If you want to help, triaging and keeping up with the issue and TODO list is great.
- Try to follow our coding style and formatting before submitting a patch.
- All merge requests should come from a feature branch created on your Git fork. Your code will be reviewed, and only merged to the master branch if it doesn't break the build.
- When you submit a merge request, try to explain what issue you're fixing, and what you're fixing in detail, so it's easier for us to read your patches.
- Well named methods and code re-usability is preferable to a lot of comments.
