When I have a IsoPcdA activity in the foreground nfc_initiator_select_passive_target() return 0, i.e. no tags found, but this same code works with Google Wallet. Might be some sort of a catch 22 situation -- the reader expecting some response to detect it as a tag, and the tag expecting something from the reader to get activated. Unfortunately I didn't get a chance to investigate further. Additionally the ATR/ATS is different depending on whether Google Wallet is installed. Will try to look into it some more. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
