# Run the 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 then with the actual fronted you need to follow these changes.

### Setup Android Studio

First of all you want to setup a working Android Studio environment. For this please download Studio from developer.android.com, and follow the instructions about how to set it up.

### Get the NewPipe code and run it.

In order to get it you must simply clone or download from the current `dev` branch github.com/TeamNewPipe/NewPipe.git. You can then build and run it following these instructions. Please 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 be 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 marven *.jar packages for android and java based on a github or gitlab repositories.

To the extractor through jitpack, you need to push them 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. Now copy your repository url in Http format, go to jitpack, and past it there From here you can grap the latest commit via `GET IT` button. I recomend not to use SNAPSHOT, since I am not sure when snapshot is build. 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.

Your browser does not support the video tag.

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

### Trouble shoot

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 is red it already shows that the build failed.
