1.在功能清单中添加对应的权限
---短信读写权限
<uses-permission android:name="android.permission.SEND_SMS" />
<uses-permission android:name="android.permission.READ_SMS" />
<uses-permission android:name="android.permission.RECEIVE_SMS" />
---获取位置的权限
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /><!-- 获取准确GPS坐标的权限 -->
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION" /><!-- 允许模拟器模拟位置的权限 -->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /><!-- 获取粗略坐标的位置权限（网络定位时使用） -->
2.在功能清单中添加Service
<service android:name="com.smartdot.mobilesafe.service.LocationService"/>
3.Java代码
package com.smartdot.mobilesafe.service;
import android.app.Service;
import android.content.Intent;
import android.location.Criteria;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.os.IBinder;
import android.telephony.SmsManager;
/**
