如何在Android中读取NFC标签并调用Web服务

Question

I'm now developing an android application with the NFC concept . In that application I need to pick my application if I swipe the NFC card and if I select my application my application must start calling webservice.

when it comes to my problem, If suppose my app crashed ,when I swipe the card next time ,the option to choose the application doesn't open .Instead,my application directly launched and couldn't call the webservice data.

On the whole.I'm getting last page when it crashed .But I need to open as fresh

I came to know that I need to make changes in OnResume() and OnNewIntent() .

I used , In OnResume()

    super.onResume();
         mNfcAdapter.enableForegroundDispatch(this, nfcPendingIntent,      mNdefExchangeFilters, null);
if (NfcAdapter.ACTION_NDEF_DISCOVERED.equals(getIntent().getAction())) {
NdefMessage[] msgs = getNdefMessages(getIntent());

byte[] payload = msgs[0].getRecords()[0].getPayload();


//Toast.makeText(this, new String(payload), Toast.LENGTH_LONG).show();
Student=new String(payload);



if(Student.equals(rakesh)
{
new Webservice.execute("");  // Calling SOAP Webservice
}

But,I can't find any changes with my problem .and one more thing that the problem will be resolve after I just open and close an another NFC project

Please help.

Answer 1

Yeah ! I got the solution .I forget a simple thing that I left calling onStop() method and my problem was,when my application stops(when Crashed).It runs in background as the previous activity.

I just tried the following,

   public void onStop()
{
super.onStop();
this.finish();
}

This may be helpful to others.

Thanks..
