So we're working on creating Android Material Awesome, a library which will hopefully incorperate the benefits of Material Design, Twitter's Bootstrap, and FontAwesome. What we really wanted is a project other people can easily include into their projects using gradle dependencies. To do this we needed to create a standalone library project so we could make it as lightweight as possible for including as a dependency, and a sample app that would use it for testing. These are the steps we took to get started in Android Studio (version 1.1).
The first thing we needed to do was to create two new projects, with all the default settings (Blank Activity etc). One for our sample app, and one for our library. We added both of ours into the same GitHub repo, however you can save them wherever you like.
Simple guide for setting up OTG modes on the Raspberry Pi Zero - By Andrew Mulholland (gbaman).
The Raspberry Pi Zero (and model A and A+) support USB On The Go, given the processor is connected directly to the USB port, unlike on the B, B+ or Pi 2 B, which goes via a USB hub.
Because of this, if setup to, the Pi can act as a USB slave instead, providing virtual serial (a terminal), virtual ethernet, virtual mass storage device (pendrive) or even other virtual devices like HID, MIDI, or act as a virtual webcam!
It is important to note that, although the model A and A+ can support being a USB slave, they are missing the ID pin (is tied to ground internally) so are unable to dynamically switch between USB master/slave mode. As such, they default to USB master mode. There is no easy way to change this right now.
It is also important to note, that a USB to UART serial adapter is not needed for any of these guides, as may be documented elsewhere across the int

For this method, alongside your Pi Zero, MicroUSB cable and MicroSD card, only an additional computer is required, which can be running Windows (with Bonjour, iTunes or Quicktime installed), Mac OS or Linux (with Avahi Daemon installed, for example Ubuntu has it built in).
1. Flash Raspbian Jessie full or Raspbian Jessie Lite onto the SD card.
2. Once Raspbian is flashed, open up the boot partition (in Windows Explorer, Finder etc) and add to the bottom of the config.txt
file dtoverlay=dwc2
on a new line, then save the file.
3. If using a recent release of Jessie (Dec 2016 onwards), then create a new file simply called ssh
in the SD card as well. By default SSH i
