Is there a unique Android device ID?
In the licensing documentation the android developers mention an easy way to more or less securely identify an android device. They are using android.Settings.Secure.ANDROID_ID.
在许可文档中，android 开发人员提到了一种或多或少安全地识别 android 设备的简单方法。他们正在使用 android.Settings.Secure.ANDROID_ID。
They say they query the system settings for this. But they don't explain this any further.
他们说他们会为此查询系统设置。但他们没有进一步解释这一点。

It's all in the Javadoc, as linked to by this question you edited 30 minutes before this one! :)

这一切都在 Javadoc 中，正如您在此问题之前 30 分钟编辑的问题所链接的那样！:)
是否有唯一的 Android 设备 ID？
The "Secure" part just means that apps can't write to it, only read. I seem to recall that this device ID isn't always present; it's populated by the Market as required, perhaps.
“安全”部分只是意味着应用程序不能写入，只能读取。我似乎记得这个设备 ID 并不总是存在；它可能根据需要由市场填充。

adb shell sqlite3 /data/data/com.android.providers.settings/databases/settings.db "SELECT value FROM secure WHERE name='android_id'"
The android id is changeable with a rooted phone... Insert a android id with:
android id 可以使用 root 手机更改...插入一个 android id：
adb shell sqlite3 /data/data/com.android.providers.settings/databases/settings.db "UPDATE secure SET value='IDHERE' WHERE name='android_id'"
