讀取sim卡的序列號，保存起來，一旦sim發(fā)生變更了，認(rèn)為是小偷的sim卡，發(fā)出警告
讀取sim卡序列號
獲取TelephonyManager對象，通過getSystemService(TELEPHONY_SERVICE)
調(diào)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里面
需要加權(quán)限 android.permission.READ_PHONE_STATE
檢測sim卡是否變更
使用廣播接收者，監(jiān)聽手機(jī)的開機(jī)廣播
新建一個(gè)包 xxx.receiver，新建一個(gè)類BootCompleteReceiver.java
清單文件注冊一下，添加<receiver>節(jié)點(diǎn)，設(shè)置名稱android:name=”xxx”
添加意圖過濾器<intent-filter>節(jié)點(diǎn)
添加動作<action/>節(jié)點(diǎn)，設(shè)置監(jiān)聽動作名稱android.intent.action.BOOT_COMPLETED
在BootCompleteReceiver類里面的onReceive()方法里，接收到廣播，讀取當(dāng)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(fā)送短信給安全號碼
監(jiān)聽開機(jī)啟動需要權(quán)限 android:perission.RECEIVE_BOOT_COMPLETED
