Question

我创建了一个动态短信收到的接收器，但它不工作需要你的帮助...... 我从我的一部手机发送短信24685端口并在其他手机上运行下面提到的代码，但不知道为什么我没有在该端口上收到任何短信.. 为了您的信息，我收到了我的第一部手机的发送报告，但我的接收器无法检测到该消息....

public class TestingSMSReceiverActivity extends Activity {
private Context context;
private MessageReceivedReceiver messageReceivedReceiver;
private String port="24685";
private short sendPort= 24685;
private TextView tv;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    tv=(TextView) findViewById(R.id.tv);
    context=getApplicationContext();
    openReceiver();

}

public class MessageReceivedReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context arg0, Intent arg1) {
        showLog("MessageReceivedReceiver Message Received");
        Toast.makeText(context, "SMS Received", Toast.LENGTH_SHORT).show();

        try
        {

                if (bundle != null)
                {
                    //---retrieve the SMS message received---
