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.
