According documentation, connect and format of NdefFormatable may cause RF
activity and may block.
They recommend call close from another thread. This not worked for me,
because when i call close, the thread is blocked too.
This is my code:
private void formatTag(Tag tag, NdefMessage ndefMessage) throws
IOException, FormatException {
final NdefFormatable ndefFormatable = NdefFormatable.get(tag);
if (ndefFormatable == null) {
return;
}
Thread thread = new Thread() {
@Override
public void run() {
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
try {
ndefFormatable.close();
Log.v("MyApp", "Forced close NFC");
} catch (IOException e) {
Log.v("MyApp", "Disconnect failed: " + e.getMessage());
}
}
};
thread.start();
ndefFormatable.connect();
ndefFormatable.format(ndefMessage);
ndefFormatable.close();}
Note 1: the formatTag is called from a AsyncTask
Note 2: This problem occurs on LG L90 device. I have tested on Moto X (1st
generation) and the problem not happens.
