I'm building a custom tag which will use NFC for communications. It will support a large command set, and in the app there will be different buttons, one for each command. I would like to be able to disable the buttons when the tag is removed from the phone and re-enable when the tag is brought back into the phone's influence.
I didn't read the isConnected close enough. Seems this will work but will still require my app to check it multiple times a second to enable/disable the buttons. One step better than my app having to send full commands over NFC to poll.

You'll get an intent if/when it is connected again. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
