Custom Listener is Null in BroadcastReceiver

[AC Question]

I Create a BroadcastReciver and want to call a method when SMS Recived! this code work correctly in other classes but not fire in BroadcastReciver.

My BroadcastReciver.java:

public class IncomingSms extends BroadcastReceiver {
String smsBody;

private SmsListener smsListener;

public interface SmsListener {
void PassActivate();
};

public void setSmsListener(SmsListener listener) {
smsListener = listener;
}

public static final String SMS_BUNDLE = "pdus";
@Override
public void onReceive(Context context, Intent intent) {

String address = "";
Bundle intentExtras = intent.getExtras();
if (intentExtras != null) {
Object[] sms = (Object[]) intentExtras.get(SMS_BUNDLE);
String smsMessageStr = "";
for (int i = 0; i < sms.length; ++i) {
SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) sms);

smsBody = smsMessage.getMessageBody().toString();
address = smsMessage.getOriginatingAddress();
}

String strOrig = smsBody;

try {
if (strOrig.contains("_Activated_")) {
if(smsListener!=null){
smsListener.PassActivate();
}

} else {
Toast.makeText(context, "Ops", Toast.LENGTH_LONG).show();
}

} catch (Exception e) {
Toast.makeText(context, "Ops", Toast.LENGTH_LONG).show();
}

}

}

When SMS recive , I chek smsListener.But it's always null!

and My Activity:

import arfaie.navid.mei.IncomingSms.SmsListener;
public class Activate extends Activity {

private IncomingSms incomingSms;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_activate);

incomingSms = new IncomingSms();
incomingSms.setSmsListener(smsListener);

}

SmsListener smsListener = new SmsListener() {
@Override
public void PassActivate() {
Toast.makeText(getBaseContext(), "It Works", Toast.LENGTH_SHORT).show();
}
};
