Question

I am writing an application that communicates with other devices through SMSs.

I was able to implement a listener for received SMSs. The thing is that it is listening to all received messages. I would like to only listen received SMSs from a specific number.

Here is my onReceive method.

@Override
public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub
    Bundle bundle = intent.getExtras();

    Object messages[] = (Object[]) bundle.get("pdus");
    SmsMessage smsMessage[] = new SmsMessage[messages.length];
    for (int n = 0; n < messages.length; n++) {
        smsMessage[n] = SmsMessage.createFromPdu((byte[]) messages[n]);
    }

    // show first message
    Toast toast = Toast.makeText(context,
                  "Received SMS: " + smsMessage[0].getMessageBody(),
                  Toast.LENGTH_LONG);
    toast.show();
}

Answer 1

There is no way AFAIK to filter for a number just by the intent.

What you CAN do is to get phone number in the Receiver like this:

SMSMesssage msg=SMSMessage.creatFromPdu(pdu)
String origination_no = msg.getDisplayOriginatingAddress()
