讀取sim卡的序列號，保留起來，一旦sim產生變革了，以為是小偷的sim卡，收回正告

讀取sim卡序列號

獲得TelephonyManager對象，經由過程getSystemService(TELEPHONY_SERVICE)

挪用TelephonyManager對象的getSimSerialNumber()辦法，獲得String類型的序列號

把序列號保留在SharedPreences外面

須要加權限 android.permission.READ_PHONE_STATE

檢測sim卡能否變革

應用播送吸收者，監聽手機的開機播送

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，設置稱號android:name=”xxx”

添加意圖過濾器<intent-filter>節點

添加舉措<action/>節點，設置監聽舉措稱號android.intent.action.BOOT_COMPLETED

在BootCompleteReceiver類外面的onReceive()辦法裡，吸收到播送，讀取以後的sim卡序列號，比擬之前保留的sim卡序列號，假如紛歧樣就發送短信給平安號碼

監聽開機啟動須要權限 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;

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);
//讀取以後的sim卡序列號
tm=(TelephonyManager) cotext.getSystemService(Context.TELEPHONY_SERVICE);
String relSim=tm.getSimSerialNumber();
//讀取之前保留的
String saveSim=sp.getString("sim", "");
//斷定後發短信
if(saveSim.equals(relSim)){
}else{
//發送報警短息給平安號碼
System.out.println("sim卡變革了");
Toast.makeText(cotext, "sim卡變革了", 1).show();
}
}
