Answer 1

I think your question is not very specific to be answered. But to explain a bit consider the following:

• you have to turn your android device in USB host mode so that it enumerates connected USB devices
• establish a connection to your receiving device. Probably this is going to be a storage or drive with a known configuration of endpoints
• when established, use a function like bulkTransfer(UsbEndpoint endpoint, byte[] buffer, int offset, int length, int timeout), which is documented as well in the link you provided. Keep in mind to choose the correct endpoint (direction TO your storage / drive)

This is just a sketch to get you started. It's clear that there is a lot more to do..
