推荐答案

使用的手机IMEI如下所述：的 http://www.androidsoftwaredeveloper.com/2009/04/02/how-to-get-the-phone-imei/

Use the phone Imei as described here: http://www.androidsoftwaredeveloper.com/2009/04/02/how-to-get-the-phone-imei/

String imei = TelephonyManager.getDefault().getDeviceId();
if (TextUtils.isEmpty(imei)) {
   return "";
}

您需要读取手机状态的权限来访问这些数据。所以，你必须添加

You need the read phone state permission to access this data. So you have to add

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

你的清单文件。

to your manifest file.
