以小米手機爲例,手機經常使用的基本信息能夠在Settings
--> About Phone
中看到,
例以下圖:java
那麼如何獲取這些設備信息呢? Android
中 一般經過 android.os.Build
類方法能夠獲取更多手機設備信息。android
獲取手機IMEI、寬、高、是否有SD卡,RAM、ROM、SD卡、是否聯網、網絡類型程序員
默認語言,設備名,型號、廠商、Fingerprint、Android 版本、SDK版本、Google 安全patch、發佈時間、版本類型、用戶名面試
獲取手機寬、高、IMEI
信息方法以下:安全
/** * 獲取設備寬度(px) * */
public static int getDeviceWidth(Context context) { return context.getResources().getDisplayMetrics().widthPixels; } /** * 獲取設備高度(px) */
public static int getDeviceHeight(Context context) { return context.getResources().getDisplayMetrics().heightPixels; } /** * 獲取設備的惟一標識, 須要 「android.permission.READ_Phone_STATE」權限 */
public static String getIMEI(Context context) { TelephonyManager tm = (TelephonyManager) context .getSystemService(Context.TELEPHONY_SERVICE); String deviceId = tm.getDeviceId(); if (deviceId == null) { return "UnKnown"; } else { return deviceId; } }
注意:獲取IMEI
須要獲取手機狀態權限微信
<!-- 讀取手機IMEI的設備權限 -->
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
若是是Android 6.0
以後的代碼請使用動態申請權限的方法申請權限,否定會報安全異常的錯誤SecurityException
,進而致使運行報錯。網絡
如需瞭解更多 系統安全權限的內容,請看 以前寫的文章 Android 系統權限使用詳解app
