How to create an Android Application for ST dual memories
41
If a new NFC tag is detected during the MainActivity life (ie.:Activity is already in a started
state) and as activity is in launched mode set to "singleTop" ,the new intent is sent to the
activity which is in a foreground state and the onNewIntent(Intent) callback is called by the
system. Then onNewIntent(intent) callback can be overridden as following:
At this stage the activity is setup to start on NDEF intent from the System, to grab NDEF
intent while it still alive. The last action the activity must perform is to treat the received
NDEF message according the activity is designed to. Received NDEF intent carrying all the
Tag information parsed by low HW/SW layers.
Intent intent = getIntent();
 
            String action = intent.getAction(); 
 
            // Manage Intent in case the intent activate the application (automated 
launch) 
 
            // check AndroidManifest.xml 
 
            if (NfcAdapter.ACTION_NDEF_DISCOVERED.equals(action)) { 
process(intent); // call private method to treat the intent 
// storing NDEF Data  
 
 
 
           
}
@Override
public void onNewIntent(Intent intent) { 
 
String action = intent.getAction(); 
 
if (NfcAdapter.ACTION_NDEF_DISCOVERED.equals(action)) { 
  
process(intent); 
  
} 
 
 
}
