Remarks
This method will be called when a NFC-F packet has been received from a remote device. A response packet can be provided directly by returning a byte-array in this method. Note that in general response packets must be sent as quickly as possible, given the fact that the user is likely holding their device over an NFC reader when this method is called.
<p class="note">This method is running on the main thread of your application. If you cannot return a response packet immediately, return null and use the #sendResponsePacket(byte[]) method later.
