I would like to develop an Android app for an Nexus 7 (2013, Android 4.3).
Qt 5.2 and Creator shall be used.

I have installed and running Android SDK and NDK, Qt5.2 and Qt Creator.
It is working to deploy stand alone apps generated on Qt Creator and run it on the Nexus7.

The next step would be to program an app for the Nexus7 using AOA (Android Open Accessory mode).
This app shall read a serial data stream (UART) from an accessory board and process it.
This accessory board is equipped with the FT311 chip from FTDI that represents the USB host.
So the Nexus would be the USB device.

Now I don`t know how to implement an AOA interface to read the serial data from the accessory using Qt Creator.

Are there additional libs required on the development system (Win8 and Qt 5.2) e.g. to have the AOA API available?
Is there an example app available?
Does Android 4.3 provide all required libs and functions or is it necessary to make changes on the Nexus 7? If yes, which changes are required?

Many thanks for any assistance.
