如何唯一识别Android设备？ [英] How To Uniquely Identify An Android Device?

问题描述

我工作的一个应用程序（服务器Android客户端），允许用户从多个Android设备登录。当用户登录的设备上，该设备将被登记在服务器端，但我不知道如何避免重复的，所以我想知道这是否有任何机会，以唯一识别Android设备？我认为，谷歌播放和Facebook能够做到这一点。

I was working on an app (server-android client) that allow user to sign in from multiple android devices. When user logged in on a device, that device will be registered on server side, but I don't know how to avoid duplicate, so I was wondering that are there any chances to uniquely identify an android device? I think Google Play and Facebook can do that.

There are several options available, but there is no 100% guarantee that they will always work. See the android developer blog post: http://android-developers.blogspot.in/2011/03/identifying-app-installations.html

提到的最好的方法是 Settings.Secure.ANDROID_ID
