[Android]利用TelephonyManager取得電信資訊

Android可以透過TelephonyManager來取得電信資訊

1.首先需要先在AndroidManifest.xml中開放權限

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

2.利用TelephonyManager取得資訊

//以下為片段程式碼
text = (TextView) findViewById( R.id.test );
        
//取得Context.TELEPHONY_SERVICE
TelephonyManager telManager = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
//手機號碼
String lineNumber = telManager.getLine1Number();
//手機 IMEI
String imei = telManager.getDeviceId();
//手機 IMSI
String imsi = telManager.getSubscriberId();
//手機漫遊狀態
String roamingStatus = telManager.isNetworkRoaming() ? "漫遊中" : "非漫遊";
//電信網路國別
String country = telManager.getNetworkCountryIso();
//電信公司代號
String operator = telManager.getNetworkOperator();
//電信公司名稱
String operatorName = telManager.getNetworkOperatorName();
//行動網路類型
String[] networkTypeArray = {"UNKNOWN", "GPRS", "EDGE", "UMTS", "CDMA", "EVDO 0", "EVDO A", "1xRTT", "HSDPA", "HSUPA", "HSPA"};
String networkType = networkTypeArray[telManager.getNetworkType()];
//行動通訊類型
String[] phoneTypeArray = {"NONE", "GSM", "CDMA"};
String phoneType = phoneTypeArray[telManager.getPhoneType()];

text.setText("手機號碼：" + lineNumber + "\n" +
		"手機 IMEI：" + imei + "\n" +
		"手機 IMSI：" + imsi + "\n" +
		"手機漫遊狀態：" + roamingStatus + "\n" +
		"電信網路國別：" + country + "\n" +
		"電信公司代號：" + operator + "\n" +
		"電信公司名稱：" + operatorName + "\n" +
		"行動網路類型：" + networkType + "\n" +
		"行動通訊類型：" + phoneType + "\n"
		);
