Android Microchip Accessory Development Starter kit PIC24F
You do not need to have com.android.future.usb.UsbAccessory (if I understand correctly that's your question, right?). This is because this namespace contains only a backported API to enable some kind of support on Android 2.3.4 (source). So the output of the detection app is completely normal and fine.
Now, this doesn't solve your problem yet, of course. I have only one idea right now: did you follow the manual? The whole section 6.2 is relevant, but I'm thinking in particular of section 6.2.2, &quot;Preparing the hardware&quot;:

Before attempting to run the demo application, insure that the correct firmware for the demo application has been loaded into the target firmware.
The firmware for this example can be found in the &quot;Basic Accessory Demo/Firmware&quot; folder of this distribution. Open the correct project file for your hardware platform for MPLAB 8. If you are using MPLAB X, open the MPLAB.X project folder and change the configuration in the configuration drop down box. Compile and program the firmware into the device.
