安卓 ID 是
UP TO 16 characters long
最多 16 个字符长

The docs specify it as a 64-bit number (expressed as a hexadecimal string)here: https://developer.android.com/reference/android/provider/Settings.Secure.html#ANDROID_ID
文档在此处将其指定为64 位数字（表示为十六进制字符串）：https: //developer.android.com/reference/android/provider/Settings.Secure.html#ANDROID_ID
