android - NFC P2P tag intercept -

i building android app using eclipse , android sdk. implement nfc p2p function in app in sense when place 2 phones back, both send string , receive string automatically. of course happen in separate activity. have managed send custom tag (string) have been unable intercept , use afterwards in app code. how can this?

this have far:

public class mainactivity extends activity {  public nfcadapter madapter; pendingintent mpendingintent;   @override  protected void oncreate(bundle savedinstancestate) {      super.oncreate(savedinstancestate);      setcontentview(r.layout.activity_main);        madapter = nfcadapter.getdefaultadapter(this);       ndefrecord rec = ndefrecord.createuri("www.stackoverflow.com");       ndefmessage ndef = new ndefmessage(rec);       madapter.setndefpushmessage(ndef, this);  } 

i have spent lot of time trying find , understand solutions intercept tag. unsuccessfully.

thank help.

you can use foreground dispatch system receive ndef message within activity:

1. in onresume():

   pendingintent pendingintent = pendingintent.getactivity(this, 0, new intent(this, getclass()).addflags(intent.flag_activity_single_top), 0); nfcadapter nfcadapter = nfcadapter.getdefaultadapter(this); nfcadapter.enableforegrounddispatch(this, pendingintent, null, null); 

2. do upon receiving intent:

   public void onnewintent(intent intent) {     ... }
