Android/Cordova UUID可靠性 [英] Android/Cordova UUID reliability
问题描述
我正在开发依赖于设备UUID的Apache Cordova应用.我脑海中浮现出几个问题，但不幸的是，我似乎无法在任何地方找到答案.
I'm developing an Apache Cordova app that relies on the device UUID. A couple questions run through my mind but I unfortunately couldn't seem to find the answer anywhere.
- 获得的device.uuid是否在每个平台上都一样，因为我计划同时在Android和iOS上发布它?
- Cordova提供的UUID与操作系统相同吗?
- 是否有任何更改/欺骗OS/Cordova UUID的方法?(这对我很重要)
推荐答案
在Android上，它使用 android.provider.Settings.Secure.ANDROID_ID
on android it uses android.provider.Settings.Secure.ANDROID_ID
在API级别3中添加的公共静态最终字符串ANDROID_ID
public static final String ANDROID_ID Added in API level 3
64位数字(以十六进制字符串形式)，当用户首先设置设备，并且对于用户设备的生命周期.如果恢复出厂设置，该值可能会更改在设备上执行.
A 64-bit number (as a hex string) that is randomly generated when the user first sets up the device and should remain constant for the lifetime of the user's device. The value may change if a factory reset is performed on the device.
注意:当一个设备有多个用户时(某些设备上可用)运行Android 4.2或更高版本)，则每个用户都将显示为完全单独的设备，因此ANDROID_ID值对于每个用户都是唯一的.
Note: When a device has multiple users (available on certain devices running Android 4.2 or higher), each user appears as a completely separate device, so the ANDROID_ID value is unique to each user.

在iOS上，cordova在首次运行时创建一个随机字符串，该字符串仅对您的应用程序唯一，并且甚至在应用程序更新时也可能会更改.
On iOS cordova create a random string on the first run, the string is unique for your app only, and might change even on app updates.

iOS上的uuid并非设备独有，但每个设备都有所不同应用程序，用于每次安装.如果您删除和删除它，它会更改重新安装该应用程序，甚至在升级iOS甚至重新安装时升级每个版本的应用程序(在iOS 5.1中明显).uuid不是可靠的价值.
The uuid on iOS is not unique to a device, but varies for each application, for each installation. It changes if you delete and re-install the app, and possibly also when you upgrade iOS, or even upgrade the app per version (apparent in iOS 5.1). The uuid is not a reliable value.
在iOS上，您可以将我的标识符用于供应商插件 https://github.com/jcesarmobile/IDFVPlugin
On iOS you can use my identifier for vendor plugin https://github.com/jcesarmobile/IDFVPlugin
It uses the native identifier for vendor https://developer.apple.com/library/ios/documentation/uikit/reference/UIDevice_Class/Reference/UIDevice.html#//apple_ref/occ/instp/UIDevice/identifierForVendor
