Remarks
Key to specify an NFC-A polling loop annotation (as a byte array) in the extras Bundle when calling enableReaderMode(Activity,ReaderCallback,int,Bundle). This polling loop annotation will be included as a non-standard polling frame which will be reported to via android.nfc.cardemulation.HostApduService.processPollingFrames(List). If there is no explicit value set by the app, the device will emit the default annotation. Use new byte[0] as annotation in the extra to override the default and don't emit any annotation.
