淺析Android手機衛士sim卡綁定

讀取sim卡的序列號，保存起來，一旦sim發生變更了，認為是小偷的sim卡，發出警告

讀取sim卡序列號

獲取TelephonyManager對象，通過getSystemService(TELEPHONY_SERVICE)

調用TelephonyManager對象的getSimSerialNumber()方法，得到String類型的序列號

把序列號保存在SharedPreences裡面

需要加權限 android.permission.READ_PHONE_STATE

檢測sim卡是否變更

使用廣播接收者，監聽手機的開機廣播

新建一個包 xxx.receiver，新建一個類BootCompleteReceiver.java

清單文件注冊一下，添加<receiver>節點，設置名稱android:name=”xxx”

添加意圖過濾器<intent-filter>節點

添加動作<action/>節點，設置監聽動作名稱android.intent.action.BOOT_COMPLETED

在BootCompleteReceiver類裡面的onReceive()方法裡，接收到廣播，讀取當前的sim卡序列號，比較之前保存的sim卡序列號，如果不一樣就發送短信給安全號碼

監聽開機啟動需要權限 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);
//讀取當前的sim卡序列號
tm=(TelephonyManager) cotext.getSystemService(Context.TELEPHONY_SERVICE);
String relSim=tm.getSimSerialNumber();
//讀取之前保存的
String saveSim=sp.getString("sim", "");
//判斷後發短信
if(saveSim.equals(relSim)){
}else{
//發送報警短息給安全號碼
System.out.println("sim卡變更了");
Toast.makeText(cotext, "sim卡變更了", 1).show();
}
}
}
