androiduniqueidentifier

Is there an equivalent to iOS' identifierForVendor for android?

In iOS 6, [UIDevice currentDevice].identifierForVendor provides a unique ID across all the apps from a single vendor.

Is there any way to do the same thing in Android?

Solution

  • There is the Android Id:
    Generating Device-Specific Serial Number

    Note that Android is designed so you can't automatically get a full device id. Android even modified a pre-existing part of linux that would have made this possible.

    Even better than Android id: your app can request the AUTHENTICATE_ACCOUNTS permission. Then you know the user's Google id. This will be common across all apps and phones the user uses.
