Overview¶
Accessory Development Kit allows you to build USB and Bluetooth accessories to extend the capabilities of your user’s Android-powered devices. Android defines a standard protocol (AOA) that you can implement in your accessories and have it compatible with a wide range of Android devices.
Compatible Android devices¶
Android Open Accessory support is included in Android 3.1 (API Level 12) and higher, and supported through an Add-On Library in Android 2.3.4 (API Level 10) and higher. Check official documentation for more information.
Warning
If your Android device uses API level 12+, it doesn’t mean that it is ADK compatible. You should always check your smartphone/board specifications to see if they have this support.
Compatible Arduino devices¶
Your accessory should implement many features as described in building custom accessories section. Many Arduino devices have a built-in support for AOA protocol and there is a small list of what is supported:
Note
This list is community driven. There I will list only devices that me or other contributors have used. If you are pretty sure that other boards have this support, follow the contribution guidelines.
