Screencasts from the example app included in this repository:

compose-upload upload


  • Android 5.0 (API 21) to Android 11 (API 30) support
  • tiny library. 100% Kotlin and fully interoperable with Java.
  • upload files to a server with FTP, HTTP multipart/form-data or binary requests
  • be able to easily implement other upload protocols as plugins
  • handle multiple concurrent uploads in the background, even if the device is idle (Doze mode)
  • automatically retry failed uploads, with a configurable exponential backoff
  • possibility to automatically delete uploaded files when the upload is successful
  • show status in the Android Notification Center (with support for stacking notifications).
  • be able to change the underlying HTTP stack. Currently HttpURLConnection (the default) and OkHttp are supported. You can also implement your own.
  • be able to set library log level and to provide custom logger implementation
  • easily customize the notification with text, icons and actions for the different states
  • Possibility to implement your own notification handler
  • Lifecycle-Aware RequestObserver to monitor your uploads

At the core of the library there is a Service which handles multiple concurrent upload tasks in the background. It publishes broadcast intents to notify status. This way the logic is completely decoupled from the UI. You are safe launching upload requests from your fragments, activities and services without worrying about locking the thread in which you are. Check the wiki to learn how you can use it in your App.

You are also safe if your app is put in the background. All the uploads will continue to be executed also when your device is idle.

Bear in mind that if you kill your app, the service gets killed as well, as it's attached to your app's process and all the currently running uploads will be terminated abruptly.
