Android广播接收器不起作用

Question

我似乎无法弄清楚为什么我的广播接收器不起作用。我希望收到传入的短信。

我没有在清单中声明广播接收器。我以编程方式注册它们。

    public static final String SMS_RECEIVED_ACTION = "android.provider.Telephony.SMS_RECEIVED";

    IntentFilter filter = new IntentFilter(SMS_RECEIVED_ACTION);
    filter.setPriority(999);
    this.registerReceiver(smsListener, filter);

我的广播接收器是活动中定义的

public BroadcastReceiver smsListener = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        if(intent.getAction().equals(SMS_RECEIVED_ACTION)) {
            System.out.println("In broadcast receiver");
            Bundle bundle = intent.getExtras();
            SmsMessage[] msgs = null;
            String msg_from;
            if (bundle != null){
                try{
                    Object[] pdus = (Object[]) bundle.get("pdus");
                    msgs = new SmsMessage[pdus.length];
                    for(int i=0; i<msgs.length; i++){
                        msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
                        msg_from = msgs[i].getOriginatingAddress();
                        System.out.println("SMS Message from: " + msg_from);
                    }
                }catch(Exception e){
                    System.out.println("Error when receiving a message");
                }
            }
        }
    }
}; 

非常感谢任何想法。
