是Secure.ANDROID_ID唯一的每个设备？ [英] Is Secure.ANDROID_ID unique for each device?

问题描述

我用这电话：

Secure.getString(getApplicationContext().getContentResolver(), Secure.ANDROID_ID);

要获得一个UID为设备。我觉得我正在从多个设备相同的ID，虽然。如果这是可能的吗？

To get a UID for the device. I think I am getting the same ID from multiple devices though. Should this be possible?

在讨论的ID是：9774d56d682e549c，显然存在一个问题，一些设备返回这个ID <一个href="http://$c$c.google.com/p/android/issues/list?cursor=10603&updated=10603&ts=1295993403">http://$c$c.google.com/p/android/issues/list?cursor=10603&updated=10603&ts=1295993403

The ID in question is: 9774d56d682e549c and apparently there is an issue with several devices returning this ID http://code.google.com/p/android/issues/list?cursor=10603&updated=10603&ts=1295993403

推荐答案

检查到这的螺纹。然而，你应该小心，因为它的记录为可在恢复出厂设置改变。使用您自己的风险，它可以很容易地改变一个根深蒂固的手机。此外，它看起来好像有些厂商有问题，有重复号码的电话<一href="http://groups.google.com/group/android-developers/browse_thread/thread/53898e508fab44f6/84e54feb28272384">thread.根据你想要做什么，我可能wouldnt以此为UID。

Check into this thread,. However you should be careful as it's documented as "can change upon factory reset". Use at your own risk, and it can be easily changed on a rooted phone. Also it appears as if some manufacturer's have had issues with their phones having duplicate numbers thread. Depending on what your trying to do, I probably wouldnt use this as a UID.
