Need simple help about Multithread task and UI

Hello. How are you? I have already build many apps like app you want. I have experience with Photo sharing app, Video/Radio app, Spy app, Guard patrol and School management system based on Nfc Read/Write , Driver & Taxi app on GPS, Routing app based on GoogleMp,Youtubevideo, JNI(FFMPEG,OPENVPN) , Responsible mobile site Bank Management system, Driver Routing app and so on.

Dear Sir/Madam, I have over 5 years of commercial experience developing native applications in Android. What I can offer is my extensive experience in mobile development and excellent communication skills which I had acquired in my previous roles as both a team member and project lead for agile teams based in Sydney and Houston. I have built enterprise applications where I have been involved in all stages of the software development life cycle and have shared common features which require the use of threading and running operations outside the UI thread, this includes loading cursors, synchronisation of data (download and upload) to/from server, image processing/loading, and complex calculations and dynamic loading, refresh, and display of content such as on a form or list view. Please do not hesitate to contact me, I do hope you will consider my proposal and I would appreciate the opportunity to discuss this project in more detail with you.

A proposal has not yet been provided

Because I have already done this for my app. I have uploaded 2 apps on play-store, which contains feature like products listing, chat(text and file exchange), audio communication. It is a simple mechanism for uploading multiple files in different threads simultaneously and getting progress update for every file.
