Android Upload Service
Easily upload files in the background with progress notification
Easily upload files (Multipart/Binary/FTP out of the box) in the background with progress notification. Support for persistent upload requests, customizations and custom plugins. At the core of the library, there is a Service that 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. -

WebUploader
A new file uploader solution
WebUploader is a simple modern file upload component developed by the Baidu WebFE (FEX) team, mainly HTML5, supplemented by FLASH. In modern browsers, it can give full play to the advantages of HTML5, without abandoning the mainstream IE browser, using the original FLASH runtime, compatible with IE6+, iOS 6+, and android 4+. When the two sets are running, the same calling method is available for users to choose at will. Using large files to upload concurrently in fragments greatly improves the efficiency of file uploads. Fragmentation and concurrency are combined to divide a large file into multiple pieces and upload them concurrently, which greatly improves the upload speed of large files. When network problems cause transmission errors, only the error fragments need to be retransmitted instead of the entire file. In addition, fragmented transmission can track upload progress in more real-time.
