wtf is android-upload-service?

Android Upload Service is a tool that lets Android apps upload files to a server in the background, without keeping the user stuck on a waiting screen. When an app uses this library, users can start uploading a photo, video, or document and then continue using the app, or even switch to another one, while the upload quietly finishes on its own. A progress bar automatically appears in the Android notification area so the user always knows what's happening. Under the hood, the library runs a background service that can handle multiple file uploads at the same time, even when the device goes into a low-power idle state. It supports common upload methods like HTTP and FTP, and it automatically retries failed uploads with increasing wait times between attempts. The upload logic is kept completely separate from the app's visual interface, communicating status updates through broadcast messages. This design means developers can plug the upload capability into whatever their app's screens look like. This is useful for any app where users share or send files. For example, a project management app like JIRA Cloud uses it to let users attach screenshots to tickets, and Quora uses it for image uploads in posts. It's also used behind the scenes in cross-platform tools like React Native Background Upload and a Cordova upload plugin, meaning apps built outside of native Android can still take advantage of its capabilities. Any developer building an app that needs reliable file transfers, where uploads shouldn't fail just because the user minimized the app, would find this relevant. A notable design choice is that everything is customizable. Developers can swap out the underlying network engine, add their own upload protocols as plugins, and fully control how the notification looks and behaves, including grouping multiple upload notifications together. The project is also working toward a version written entirely in Kotlin with Android 10 support, reflecting an effort to stay current with modern Android development practices.
