# Contributing to Parse SDK for Android
We want to make contributing to this project as easy and transparent as possible.
## Code of Conduct
Facebook has adopted a Code of Conduct that we expect project participants to adhere to. Please read [the full text](https://code.facebook.com/codeofconduct) so that you can understand what actions will and will not be tolerated.
## Our Development Process
Most of our work will be done in public directly on GitHub. There may be changes done through our internal source control, but it will be rare and only as needed.
### `master` is unsafe
Our goal is to keep `master` stable, but there may be changes that your application may not be compatible with. We'll do our best to publicize any breaking changes, but try to use our specific releases in any production environment.
### Pull Requests
We actively welcome your pull requests. When we get one, we'll run some Parse-specific integration tests on it first. From here, we'll need to get a core member to sign off on the changes and then merge the pull request. For API changes we may need to fix internal uses, which could cause some delay. We'll do our best to provide updates and feedback throughout the process.
1. Fork the repo and create your branch from `master`.
4. Add unit tests for any new code you add.
3. If you've changed APIs, update the documentation.
4. Ensure the test suite passes.
5. Make sure your code lints.
6. If you haven't already, complete the Contributor License Agreement ("CLA").
### Contributor License Agreement ("CLA")
In order to accept your pull request, we need you to submit a CLA. You only need to do this once to work on any of Facebook's open source projects.
Complete your CLA here: <https://developers.facebook.com/opensource/cla>
## Bugs
Although we try to keep developing on Parse easy, you still may run into some issues. Technical questions should be asked on [Stack Overflow][stack-overflow], and for everything else we'll be using GitHub issues.
### Known Issues
We use GitHub issues to track public bugs. We will keep a close eye on this and try to make it clear when we have an internal fix in progress. Before filing a new issue, try to make sure your problem doesn't already exist.
### Reporting New Issues
Not all issues are SDK issues. If you're unsure whether your bug is with the SDK or backend, you can test to see if it reproduces with our [REST API][rest-api] and [Parse API Console][parse-api-console]. If it does, you can report backend bugs [here][bug-reports].
To view the REST API network requests issued by the Parse SDK and responses from the Parse backend, please check out [OkHttp Interceptors][network-debugging-tool]. With this tool, you can either log network requests/responses to Android logcat, or log them to Chrome Debugger via Stetho.
Details are key. The more information you provide us the easier it'll be for us to debug and the faster you'll receive a fix. Some examples of useful tidbits:
* A description. What did you expect to happen and what actually happened? Why do you think that was wrong?
* A simple unit test that fails. Refer [here][tests-dir] for examples of existing unit tests. See our [README](README.md#usage) for how to run unit tests. You can submit a pull request with your failing unit test so that our CI verifies that the test fails.
* What version does this reproduce on? What version did it last work on?
* [Stacktrace or GTFO][stacktrace-or-gtfo]. In all honesty, full stacktraces with line numbers make a happy developer.
* Anything else you find relevant.
### Security Bugs
Facebook has a [bounty program](https://www.facebook.com/whitehat/) for the safe disclosure of security bugs. In those cases, please go through the process outlined on that page and do not file a public issue.
## Style Guide
We're still working on providing a code style for your IDE and getting a linter on GitHub, but for now try to keep the following:
* Most importantly, match the existing code style as much as possible.
* Try to keep lines under 100 characters, if possible.
## License
By contributing to Parse Android SDK, you agree that your contributions will be licensed under its license.

Additional Grant of Patent Rights Version 2
"Software" means the Parse Android SDK software distributed by Parse, LLC.
Parse, LLC. ("Parse") hereby grants to each recipient of the Software
("you") a perpetual, worldwide, royalty-free, non-exclusive, irrevocable
(subject to the termination provision below) license under any Necessary
Claims, to make, have made, use, sell, offer to sell, import, and otherwise
transfer the Software. For avoidance of doubt, no license is granted under
Parse’s rights in any patent claims that are infringed by (i) modifications
to the Software made by you or any third party or (ii) the Software in
combination with any software or other technology.
The license granted hereunder will terminate, automatically and without notice,
if you (or any of your subsidiaries, corporate affiliates or agents) initiate
directly or indirectly, or take a direct financial interest in, any Patent
Assertion: (i) against Parse or any of its subsidiaries or corporate
affiliates, (ii) against any party if such Patent Assertion arises in whole or
in part from any software, technology, product or service of Parse or any of
its subsidiaries or corporate affiliates, or (iii) against any party relating
to the Software. Notwithstanding the foregoing, if Parse or any of its
subsidiaries or corporate affiliates files a lawsuit alleging patent
infringement against you in the first instance, and you respond by filing a
patent infringement counterclaim in that lawsuit against that party that is
unrelated to the Software, the license granted hereunder will not terminate
under section (i) of this paragraph due to such counterclaim.
A "Necessary Claim" is a claim of a patent owned by Parse that is
necessarily infringed by the Software standing alone.
A "Patent Assertion" is any lawsuit or other action alleging direct, indirect,
or contributory infringement or inducement to infringe any patent, including a
cross-claim or counterclaim.
