Hello David, Here is some code try { tag.connect(); if(tag.isConnected() && tag.isWritable()){ tag.writeNdefMessage(message); tag.close(); }
} catch (IOException e) { // TODO Auto-generated catch block } catch (FormatException e) { // TODO Auto-generated catch block } This code works for writing. I also have a problem how to detect a tag is lost. Although this code works but it can not stop on catch statment and therefore i can not implement a code if the tag is lost. john On Aug 1, 11:47 pm, David P <d.refi...@gmail.com> wrote: > Hey Nick, > > Could you please provide a code example of how to signal an event when > a "tag is lost"?
