NFC HAL sends tag recognition event to NFC Service, and wherein, described tag recognition event includes described
NDEF message；
Described NFC Service receives described tag recognition event, and broadcasts described tag recognition event；
NFC activity processes described tag recognition event, parses described NDEF and disappear from described tag recognition event
Breath, and described NDEF message is shown.
1, further, described intent is TECH_DISCOVERED intent.
The invention have the benefit that
A kind of Android client card reading method based on NFC technique, when user needs to identify nfc card, first starts movement
The NFC module of equipment, then obtains the label information of nfc card by NFC module；Afterwards, label distribution system creation intent,
This intent encapsulates the label information of above-mentioned nfc card, and now, NFC HAL obtains NDEF from the label information of nfc card and disappears
Breath, NFC HAL sends tag recognition event to NFC Service again, after NFC Service receives tag recognition event,
NFC Service broadcasts this tag recognition event；Subsequently, NFC activity receives tag recognition event, and knows from label
Parsing described NDEF message in other event, the NDEF message being resolved to shown, above-mentioned card reading method is simple to operate, real
Strong by property, the interworking of mobile phone and card can be done directly by Android mobile phone client and mobile phone NFC module, thus take
Generation NFC contactless card reader the most on the market and the conventional communication mode of card, facilitate user and technical staff to move and do
Public.
Android client card reader and card reading method that the present invention provides are simple to operate, practical, can pass through Android
Cell-phone customer terminal and mobile phone NFC module are done directly the interworking of mobile phone and card, thus replace that NFC is non-on the market at present connects
Touch the conventional communication mode of card reader and card, facilitate user and technical staff to move office.

Detailed description of the invention
Below in conjunction with the accompanying drawing 2 and Fig. 3 in embodiment of the present invention, the technical scheme in embodiment of the present invention is entered
Row clearly and completely describes.
Embodiment 1
A kind of Android client card reading method based on NFC technique, comprises the following steps:
S1: start the NFC module of mobile device, and obtained the label information of nfc card by described NFC module.
S2: label distribution system creation intent.
Wherein, described intent encapsulates the label information of described nfc card.
During practical operation, if more than one application program can process above-mentioned intent, then mobile phone interface can eject
One choice box, allows user select to process the Activity of this label.Label distribution system defines 3 kinds of intent, wherein presses
Priority is arranged as from high to low: NDEF_DISCOVERED, TECH_DISCOVERED, TAG_DISCOVERED, and the present invention makes
Use TECH_DISCOVERED intent.If NDEF_DISCOVERED intent do not starts or neither one Activity
Filter detection NDEF_DISCOVERED and this label are known, then this TECH_DISCOVERED Intent will
Start.TECH_DISCOVERED intent requires to specify the technologies list needing to support in resource file.
S3:NFC HAL obtains NDEF message from the label information of described nfc card.
S4:NFC HAL sends tag recognition event to NFC Service, and wherein, described tag recognition event includes described
NDEF message.
