received. Further, you could use another graphic to indicate when

the recipient has received the message. Alternatively, you could

use ProgressBar widgets track the progress to the user.

Receiving an SMS

Applications can also receive SMS messages. To do so, your

application must register a BroadcastReceiver to listen for the

Intent action associated with receiving an SMS. An application

listening to SMS in this way doesn’t prevent the message from

getting to other applications.

Expanding on the previous example, the following code shows how

any incoming text message can be placed within a TextView on the

screen:

final TextView receivedMessage = (TextView)findViewById(
R.id.received_message);
rcvIncoming = new BroadcastReceiver() {
public void onReceive(Context context, Intent intent) {
Log.i(“telephony”, “SMS received”);
Bundle data = intent.getExtras();
if (data != null) {
Object pdus[] = (Object[]) data.get(“pdus”);
String message = “New message:\n”;
String sender = null;
for (Object pdu : pdus) {
SmsMessage part = SmsMessage.
createFromPdu((byte[])pdu);
message += part.getDisplayMessageBody();
(sender == null) {
sender = part.
getDisplayOriginatingAddress();
}
}
receivedMessage.setText(message + “\nFrom: “+sender);
numberEntry.setText(sender);
}
}
};
registerReceiver(rcvIncoming, new IntentFilter(
“android.provider.Telephony.SMS_RECEIVED”));
