Sample app for the Host-based Card Emulation released in Android 4.4

This app is a simple demo app where most of the code was taken from the Host-based Card Emulation documentation at:

The HostApduService will simply wait for a SELECT AID apdu and then start a simple message exchange. Every message gets a unique message number.

You can find a precompiled APK in the releases section of this repository.

This app is used in conjunction with a demo app based on the NfcTools for Java project where a connection from an ACR122U desktop NFC reader is made. The reader will connect to this app and exchange arbitrary messages with the Android device.

Have a look at the blog post how this all works together:

I've also updated this app to demonstrate the Reader-Mode in Android 4.4 which allows you to communicate to a second Android device in host-based card emulation mode.

For the time being you need an Android 4.4 device for this to work.
