Everyone is welcome to contribute with suggestions or pull requests, as the library is under active development, although it has reached a high level of stability.

We are grateful to anyone who has contributed with fixes, features or feature requests. If you don’t want to get involved but still want to support the project, please consider donating.

Bug reports

Please make sure to fill the bug report issue template on GitHub. We highly recommend to try to reproduce the bug in the demo app, as this helps a lot in debugging and excludes programming errors from your side.

Make sure to include:

  • A clear and concise description of what the bug is
  • Library version, device type, Android API level
  • Exact steps to reproduce the issue
  • Description of the expected behavior

Recommended extras:

  • Screenshots
  • LogCat logs (use ZoomLogger.setLogLevel(LEVEL_VERBOSE) to print all)
  • Link to a GitHub repo where the bug is reproducible

Pull Requests

Please open an issue first.

Unless your PR is a simple fix (typos, documentation, bugs with obvious solution), opening an issue will let us discuss the problem, take design decisions and have a reference to the issue description.

Writing unit tests will be highly appreciated.
