浅析Android手机卫士sim卡绑定
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
packagecom.qingguow.mobilesafe.receiver;
importandroid.content.BroadcastReceiver;
importandroid.content.Context;
importandroid.content.Intent;
importandroid.content.SharedPreferences;

@Override
publicvoidonReceive(Contextcotext,Intentarg1){
sp=cotext.getSharedPreferences("config",Context.MODE_PRIVATE);
//读取当前的sim卡序列号
tm=(TelephonyManager)cotext.getSystemService(Context.TELEPHONY_SERVICE);
StringrelSim=tm.getSimSerialNumber();
//读取之前保存的
StringsaveSim=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();
}
}
}
