WebAPI/WebNFC: Difference between revisions

1. Gaia applications, in order to read NDEF messages from a passive tag (or) P2P phone, should declare 'nfc-ndef-discovered' in their manifest file.This implies that the Gaia application shall be listed in activity picker whenever an NDEF message is about to be read. However, if the Gaia application wishes to perform write operation after reading, it can choose to do so by using the API 'writeNDEF()'. (provided user has picked the Nfc Application as his choice in the activity picker)

 

2. In order to write NDEF message (No need to declare 'nfc-ndef-discovered' in its manifest file)

 

a) In a P2P mode, Gaia applications shall register for 'onpeerready' as described above

b) In Passive Tag mode, {{bug|937430}} is still under discussion.

These APIs should be used if the application wants to bypass the normal activity picker. As you may also have noted , for these event handlers to be fired, the Nfc Gaia

application should be the top-visible / foreground application.
