I highly recommend you to use Square's Tape while your uploading multiple files/images at once looking at the ease of use, efficiency,error handling, queuing system. If you are using only one file at time try to use any of multi-part file upload in any android Http clients

This is what [Square's Tape:][1]

Tape is a collection of queue-related classes for Android and Java by Square, Inc.

QueueFile is a lightning-fast, transactional, file-based FIFO. Addition and removal from an instance is an O(1) operation and is atomic. Writes are synchronous; data will be written to disk before an operation returns. The underlying file is structured to survive process and even system crashes and if an I/O exception is thrown during a mutating change, the change is aborted.

An ObjectQueue represents an ordering of arbitrary objects which can be backed either by the filesystem (via QueueFile) or in memory only.

TaskQueue is a special object queue which holds Tasks, objects which have a notion of being executed. Instances are managed by an external executor which prepares and executes enqueued tasks.
