You need to enableForegroundDispatch() on every activity that is supposed to be watching for NFC tag events. From what I've read, if Activity A enables dispatch and Activity B is in the foreground, the dispatch doesn't happen.
Also, to get onNewIntent() to work, make sure your Intent inside the PendingIntent has FLAG_ACTIVITY_CLEAR_TOP|FLAG_ACTIVITY_SINGLE_TOP as its flags. Here is a sample application demonstrating this: https://github.com/commonsguy/cw-advandroid/tree/master/NFC/URLTagger On Tue, Jun 14, 2011 at 5:52 AM, Ferit T <[email protected]> wrote: > Hi, > > i'm a relatively new to the android development so there could be some > dummy question.
