What is mattdownloader?

MattDownloader GitHub Relay is a GitHub Actions template that helps an Android app called MattDownloader fetch files more reliably. Instead of downloading a file straight to a phone, the workflow runs the download on a GitHub server, saves the result inside a fork of this template under a jobs folder, and lets the app pick it up from there later. The idea came from another project and is meant as a stable relay for times when direct phone downloads are slow, blocked, or unreliable. This repository only contains the workflow files and setup instructions. There is no mobile app source code here and no APK stored in the repository, the APK has to be downloaded separately from the Releases page. To use it, a person forks the repository, ideally with a separate GitHub account rather than their main one, since all forking, workflow runs, and downloaded files will live under whichever account is used. After forking, they turn on GitHub Actions for the fork, install the MattDownloader app, and create a fine-grained personal access token scoped only to that fork, with read-only access to contents and read and write access to Actions. That token and the fork's address are then entered into the app. Once set up, giving the app a file link makes it trigger the workflow on the fork, wait for a manifest file to appear, and then download the prepared file from GitHub. Large files are split into chunks of about 95 megabytes so the GitHub API can handle them. There are also workflows for deleting a finished job and for cleaning up old job folders automatically. The README recommends using a limited-scope token rather than one with broad account access, since that reduces what could go wrong if the token were exposed. The project is released under the MIT License and includes optional cryptocurrency donation addresses for anyone who finds the template useful.
