广播接收者在模拟器上可以实现，但是在小米3上没有效果

如题
代码为：
package com.sed.ipcall;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;

public class IpReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    System.out.println("我监听到了有新电话拨出。。。");
    //获取拨打的号码
    String number = getResultData();
    //取到保存的值
    SharedPreferences sp = context.getSharedPreferences("ipnumber",
            Context.MODE_PRIVATE);
    number = sp.getString("ipnumber", "") + number;
    //设置值
    System.out.println(number);

    setResultData(number);
}

}
