You should build it using the multipart upload API. Here's the link for Java:

The idea would be to initiate a multi-part upload, start uploading parts (whose size would be based on the client's transfer rate) and whenever the user pauses the upload, stop uploading parts. You won't have byte by byte pause granularity, but I suspect the user would not notice that.
