Android: add Java class to receive Intents

We want to be able to respond to a USB device being plugged in.
This simply logs the information we get from the device. Sadly the
really useful getProductName and getManufacturerName require API level
21 (so Android 5.0 or newer) and we still have a couple hundred users on
4.1-4.4.
