HB Blog 8: Google develop custom Android edition for Project Ara.

Google is working with open-source development organization to develop a special edition of Android for the Project Ara customizable smartphone.
The $50 configurable smartphone will come with an empty phone frame and screen, and users can snap on or take out modular parts from the rear of the handset to add or remove features.
The smartphone, which will ship early next year, has already sparked the development of Lego-like modules that can be attached. Google has talked about detachable antenna and camera modules, but developers are also considering modules for wireless networking, gaming, storage and thermometers.

 Android can already plug and play SD cards. But additional OS functionality is needed for storage, cameras and other modules that are typically inside smartphones, but can now be externally added to Project Ara.
A lot of work is also being done on UniPro transport drivers, which connect modules and components in Project Ara. UniPro protocol drivers in Android will function much like the USB protocol, where modules will be recognized based on different driver “classes,” such as those for networking, sensor, imaging, input and others.
Some attachable parts may not be recognized by Android. For those parts, separate drivers need to be developed by module makers through emulators.

Google already offers a module developers kit (MDK) for Project Ara platform through which developers can take advantage of the UniPro hardware and protocol stack.

Project Ara is Google’s attempt to reinvent the cellphone as we know it. Instead of a slab of glass and metal that you have no ability to upgrade, save for buying a new device, it’s an attempt to launch a phone where all of the main components are interchangeable via modules that click in and out, attaching via electro-permanent magnets. Despite being highly customizable, it will only come in three main sizes, helping to eliminate the kind of device fragmentation that currently plagues Android. Google plans to roll out a “gray model,” a very basic device that costs as little as $50, as well as higher-end handsets that could go for as much as $500 and up. The former will be released first — around this time next year if all goes according to plan — and will likely be a smaller, Wi-Fi-only version. This bare-bones model will be followed by the higher-end ones eventually. But Google’s initial objective is to ramp up a hardware ecosystem that moves at the same pace as the software it runs.
