Dear members of this community,

I am currently working on an Android Studio project aimed at developing a live wallpaper application with high functionality, albeit at a relatively low visual fidelity. My goal is to leverage the rapid graphics capabilities offered by Processing while integrating Android device sensors to create dynamic and interactive visuals directly on the screen.

As part of this endeavor, I require a **genuine copy of the `processing-core.jar` file** to include in my Android Studio project. Unfortunately, I have encountered difficulties in locating a verified and trustworthy source for this file, and I suspect that the file I currently possess may not be authentic or complete.

Therefore, I kindly ask for assistance in identifying where I can obtain the official and unmodified `processing-core.jar`, preferably from the original developers or a trusted repository such as the official Processing website ([https://processing.org/download/](https://processing.org/download/)) or the gradle repository.  
Any guidance or support you can offer would be greatly appreciated, especially if you have experience integrating Processing into Android development projects or have previously dealt with similar issues regarding library sourcing and integration

Thank you in advance for your time and assistance.

I don’t have a lot of experience with AndroidStudio, but when I have done this in the past I copied it from the current app bundle. Recently there have been several new versions of the Processing IDE so it would change with each version. With version 4.4.4 it is located at the following path:

Processing.app/contents/app/resources/core/library.

It starts with a right click on your Processing app and selecting ‘Show Package Contents’ from the menu, then start opening folders and drilling down to find it. Below is what it looks like on my macOS system:

 ![core](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/3X/0/2/02ea5031d2caa1a7c85b75a160c3aa0793f17692.png)

The developers may be able to steer you to some other source which I am not aware of.

Hi @Mardin98K

Are you intending to deploy this project on Android? In that case you will need the Android version of Processing Core which is part of Android Mode:

> **[GitHub - processing/processing-android: Processing mode and core library to create Android...](https://github.com/processing/processing-android)**
>
> Processing mode and core library to create Android apps with Processing

If you intend to deploy to desktop you can find the Processing core.jar on Maven Central here:

> **[Maven Central: org.processing:core](https://central.sonatype.com/artifact/org.processing/core)**
>
> Discover core in the org.processing namespace. Explore metadata, contributors, the Maven POM file, and more.
