Testing Your Changes in the App

You should develop and test your changes with the JUnit environment that is provided by the NewPipe Extractor and IDEA. If you want to try it with the actual fronted, you need to follow these steps.

Setup Android Studio

First, you'll want to set up a working Android Studio environment. To do this, download Studio from developer.android.com, and follow the instructions on how to set it up.

Get the NewPipe Code and Run it.

In order to get it, you simply clone or download it from the current dev branch github.com/TeamNewPipe/NewPipe.git. You can then build and run it following these instructions. Also, make sure you are comfortable with adb since you might experience some trouble running your compiled app on a real device, especially under Linux, where you sometimes have to adjust the udev rules in order to make your device accessible.

Run Your Changes on the Extractor

In order to use the extractor in our app, we use JitPack. This is a build service that can build maven *.jar packages for Android and Java based on GitHub or GitLab repositories.

To use the extractor through JitPack, you need to push it to your online repository of your copy that you host either on GitHub or GitLab. It's important to host it on one of both. To copy your repository URL in HTTP format, go to JitPack and paste it there. From here, you can grab the latest commit via GET IT button. I recommend not to use a SNAPSHOT, since I am not sure when snapshot is built. An "implementation" string will be generated for you. Copy this string and replace the implementation 'com.github.TeamNewPipe:NewPipeExtractor:<commit>' line in the file /app/build.gradle with it.

If everything synced well, then you should only see a screen with OK signs. Now you can compile and run NewPipe with the new extractor.

Troubleshooting

If something went wrong on JitPack site, you can check their build log, by selecting the commit you tried to build and click on that little paper symbol next to the GET IT button. If it's red, it means that the build failed.
