Extending the Android Framework with New Devices

Submitted Oct 17, 2011

This session will show you how to add support for a completely new device on Android. This includes adding a new device driver, extending the Android framework to support the new device, and taking care of application level interfaces.

We have two speakers in this talk : Shree Kumar and Nitheesh K L.


Android is expected to proliferate across a wide variety of devices in a relatively short time. General purpose computing devices support a lot more hardware than Android does. There is a need to support new types of devices in Android, the ones that are not yet supported.

Adding support for a new device type requires work at all levels. You need to take care of the kernel level, framework and API interfaces for user applications. Adding to this complexity, Android compatibility prohibits you from changing the platform API.

This talk will show you how to add support for a new device type. We will demonstrate

  • incorporating linux drivers into the android linux kernel

  • creating a platform library that adds support for the new device

  • creating a service that accesses the device and exposes it to apps

  • creating an API that apps can use to access the device

  • how external developers can use this API to target your device.

We will demonstrate these steps by integrating a joystick and an industrial barcode scanner.


Basic understanding of android applications. Some knowledge of android architecture is desirable.
