6.2.1 Getting the Android Application

There are several methods for getting the example Android application running on the target Android device. Before

attempting any of these methods, please insure that the Android device is running the appropriate version of the Android OS

(Updating the Android OS ( see page 37)).

Once the proper OS version is installed, please use one of the following methods to get the application into the Android

device.

6.2.1.1 From source

The source code for the example Android application is included in this installation. You should be able to compile and use

the IDE of your choice to directly load the example application as you would any other Android example program. Once the

application is loaded on the Android device you can remove the USB connection to the IDE and connect it to target

accessory to run the demo.

6.2.1.2 From Android Marketplace

The example application can be downloaded from the Android Marketplace. You should be able to find the demo application

by searching for "Microchip" and looking for the "Basic Accessory Demo" application.

You can also download the file by:

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.
