浅析Android手机卫士之手机实现短信指令获取位置

发送短信，SmsManager.getDefault().sendTextMessage()方法，发送短信给安全号码，参数：sendTextMessage(目标手机, null(来源手机不支持), text, sentIntent, deliveryIntent)后两个参数，延迟报告和送达报告，不关心填null

需要这个权限 android.permission.SEND_SMS

判断一下内容是否为空，如果为空发送短信内容是正在获取，手动让坐标变化一下，才能正在得到

GPSService.java

package com.qingguow.mobilesafe.service;import android.app.Service;import android.content.Intent;import android.content.SharedPreferences;import android.content.SharedPreferences.Editor;import android.location.Criteria;import android.location.Location;import android.location.LocationListener;import android.location.LocationManager;import android.os.Bundle;import android.os.IBinder;public class GPSService extends Service {private LocationManager lm;private LocationListener listener;private SharedPreferences sp;@Overridepublic IBinder onBind(Intent arg0) {return null;}// 服务创建@Overridepublic void onCreate() {super.onCreate();sp=getSharedPreferences("config", MODE_PRIVATE);// 获取位置管理器lm = (LocationManager) getSystemService(LOCATION_SERVICE);listener = new MyLocationListener();Criteria criteria = new Criteria();criteria.setAccuracy(Criteria.ACCURACY_FINE);String provider = lm.getBestProvider(criteria, true);lm.requestLocationUpdates(provider, 0, 0, listener);}// 服务销毁@Overridepublic void onDestroy() {super.onDestroy();lm.removeUpdates(listener);listener=null;}private class MyLocationListener implements LocationListener {@Overridepublic void onLocationChanged(Location location) {// 获取经度String longitude = "longitude：" + location.getLongitude();String latitude = "latitude：" + location.getLatitude();String acc = "accuracy：" + location.getAccuracy();// 转换火星坐标try {ModifyOffset offset = ModifyOffset.getInstance(getAssets().open("axisoffset.dat"));PointDouble pinit = offset.s2c(new PointDouble(location.getLongitude(), location.getLatitude()));longitude = "longitude：" + pinit.x;latitude = "latitude：" + pinit.y;} catch (Exception e) {e.printStackTrace();}//保存数据Editor editor=sp.edit();editor.putString("lastlocation", longitude+latitude+acc);editor.commit();}@Overridepublic void onStatusChanged(String provider, int status, Bundle extras) {}@Overridepublic void onProviderEnabled(String provider) {}@Overridepublic void onProviderDisabled(String provider) {}}}

SmsReceiver.java

package com.qingguow.mobilesafe.receiver;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.content.SharedPreferences;import android.media.MediaPlayer;import android.telephony.SmsManager;import android.telephony.SmsMessage;import android.text.TextUtils;import com.qingguow.mobilesafe.R;import com.qingguow.mobilesafe.service.GPSService;public class SmsReceiver extends BroadcastReceiver {private SharedPreferences sp;@Overridepublic void onReceive(Context context, Intent intent) {sp=context.getSharedPreferences("config", Context.MODE_PRIVATE);//获取短信内容Object[] objs=(Object[]) intent.getExtras().get("pdus");for(Object obj:objs){SmsMessage sms=SmsMessage.createFromPdu((byte[])obj);String body=sms.getMessageBody();String sender=sms.getOriginatingAddress();String secSender=sp.getString("secphone", "");//判断是安全号码的短信if(secSender.equals(sender)){switch (body) {case "#*alarm*#"://发送报警音乐//Toast.makeText(context, "播放报警音乐", 1).show();MediaPlayer mp=MediaPlayer.create(context, R.raw.alarm);mp.start();abortBroadcast();break;case "#*location*#"://得到位置信息Intent intent1=new Intent(context,GPSService.class);context.startService(intent1);String lastLocation= sp.getString("lastlocation", "");//发送短信if(TextUtils.isEmpty(lastLocation)){SmsManager.getDefault().sendTextMessage(sender, null,"getting location", null, null);}else{SmsManager.getDefault().sendTextMessage(sender, null,lastLocation, null, null);}System.out.println("获取位置消息"+lastLocation);abortBroadcast();break;default:break;}}}}}
