[android] 手机卫士绑定sim卡

更新：

收不到启动广播，查看知乎，好像是说高版本的系统都禁止了

还可以通过adb发送开机广播

adb shell am broadcast -a android.intent.action.BOOT_COMPLETED

还没测试，回去再测试

========================== 

读取sim卡的序列号，保存起来，一旦sim发生变更了，认为是小偷的sim卡，发出警告

读取sim卡序列号

获取TelephonyManager对象，通过getSystemService(TELEPHONY_SERVICE)

调用TelephonyManager对象的getSimSerialNumber()方法，得到String类型的序列号

把序列号保存在SharedPreences里面

需要加权限 android.permission.READ_PHONE_STATE

检测sim卡是否变更

使用广播接收者，监听手机的开机广播

新建一个包 xxx.receiver，新建一个类BootCompleteReceiver.java

清单文件注册一下，添加<receiver>节点，设置名称android:name=”xxx”

添加意图过滤器<intent-filter>节点

添加动作<action/>节点，设置监听动作名称android.intent.action.BOOT_COMPLETED

在BootCompleteReceiver类里面的onReceive()方法里，接收到广播，读取当前的sim卡序列号，比较之前保存的sim卡序列号，如果不一样就发送短信给安全号码

监听开机启动需要权限 android:perission.RECEIVE_BOOT_COMPLETED

BootCompleteReceiver.java

package com.qingguow.mobilesafe.receiver;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.telephony.TelephonyManager;
import android.widget.Toast;

public class BootCompleteReceiver extends BroadcastReceiver {
    private TelephonyManager tm;
    private SharedPreferences sp;
    @Override
    public void onReceive(Context cotext, Intent arg1) {
        sp=cotext.getSharedPreferences("config", Context.MODE_PRIVATE);
        //读取当前的sim卡序列号
        tm=(TelephonyManager) cotext.getSystemService(Context.TELEPHONY_SERVICE);
        String relSim=tm.getSimSerialNumber();
        //读取之前保存的
        String saveSim=sp.getString("sim", "");
        //判断后发短信
        if(saveSim.equals(relSim)){
            
        }else{
            //发送报警短息给安全号码
            System.out.println("sim卡变更了");
            Toast.makeText(cotext, "sim卡变更了", 1).show();
        }
    }

}
