NewPipe contribution guidelines

Crash reporting

Report crashes through the automated crash report system of NewPipe. This way all the data needed for debugging is included in your bugreport for GitHub. You'll see exactly what is sent, be able to add your comments, and then send it.

Issue reporting/feature requests

Already reported? Browse the existing issues to make sure your issue/feature hasn't been reported/requested.
Already fixed? Check whether your issue/feature is already fixed/implemented.
Still relevant? Check if the issue still exists in the latest release/beta version.
Can you fix it? If you are an Android/Java developer, you are always welcome to fix an issue or implement a feature yourself. PRs welcome! See Code contribution for more info.
Is it in English? Issues in other languages will be ignored unless someone translates them.
Is it one issue? Multiple issues require multiple reports, that can be linked to track their statuses.
The template: Fill it out, everyone wins. Your issue has a chance of getting fixed.

Translation

NewPipe is translated via Weblate. Log in there with your GitHub account, or register.
Add the language you want to translate if it is not there already: see How to add a new language in the wiki.

Code contribution

Guidelines

Stick to NewPipe's style conventions of checkStyle and ktlint. They run each time you build the project.
Stick to F-Droid contribution guidelines.
In particular do not bring non-free software (e.g. binary blobs) into the project. Make sure you do not introduce Google closed-source libraries.

Before starting development

If you want to help out with an existing bug report or feature request, leave a comment on that issue saying you want to try your hand at it.
If there is no existing issue for what you want to work on, open a new one describing your changes. This gives the team and the community a chance to give feedback before you spend time on something that is already in development, should be done differently, or should be avoided completely.
Please show intention to maintain your features and code after you contribute a PR. Unmaintained code is a hassle for core developers. If you do not intend to maintain features you plan to contribute, please rethink your submission, or clearly state that in the PR description.
Send PRs that only cover one specific issue/solution/bug. Do not send PRs that are huge and could be split into multiple independent contributions.

Creating a Pull Request (PR)

Make changes on a separate branch with a meaningful name, not on the master branch or the dev branch. This is commonly known as feature branch workflow. You may then send your changes as a pull request (PR) on GitHub.
Please test (compile and run) your code before submitting changes! Ideally, provide test feedback in the PR description. Untested code will not be merged!
Respond if someone requests changes or otherwise raises issues about your PRs.
Try to figure out yourself why builds on our CI fail.
Make sure your PR is up-to-date with the rest of the code. Often, a simple click on "Update branch" will do the job, but if not, you must rebase the dev branch manually and resolve the problems on your own. You can find help on the wiki. That makes the maintainers' jobs way easier.

Build instructions

Basic setup

NewPipe is developed using Android Studio. The setup is fairly simple:

Clone the NewPipe repository with git clone https://github.com/TeamNewPipe/NewPipe.git (or use your fork)
Open the folder you just cloned with Android Studio
Build and run just like you would do with any other app, with the green triangle in the top bar

checkStyle setup

The checkStyle plugin verifies that Java code abides by the project style. It runs automatically each time you build the project, though to be able to view errors directly in the editor, insead of having to skim through the build output, you can install an Android Studio plugin:

Go to File -> Settings -> Plugins, search for checkstyle and install CheckStyle-IDEA
Go to File -> Settings -> Tools -> Checkstyle
Add NewPipe's configuration file by clicking the upper + on the right
Under the "Use a local Checkstyle file" label, click on Browse and pick the file named checkstyle.xml in the project's root folder
Enable "Store relative to project location" so that moving the directory around does not create issues
Insert a description in the top bar, then click Next, then Finish
Activate the configuration file you just added by enabling the checkbox on the left
Click Ok and you are done

ktlint setup

The ktlint plugin does the same job as checkStyle for Kotlin files. Installing the related plugin is as simple as going to File -> Settings -> Plugins, searching for ktlint and installing Ktlint (unofficial).

Communication

The #newpipe channel on Libera Chat (ircs://irc.libera.chat:6697/newpipe) has the core team and other developers in it. Click here for webchat!
You can also use a Matrix account to join the NewPipe channel at #newpipe:libera.chat. We suggest using Element as a Matrix client, available both for phone and desktop.
Post suggestions, changes, ideas etc. on GitHub or IRC.
