Bear in mind that this ID is stored in a SQLite database and can be modified on rooted phones. Also bear in mind that there is only modest coordination on ANDROID_ID. For example, ARCHOS shipped their first Internet table where the ANDROID_ID value did not correspond to the API documentation (wasn't a hex string). This may be because they do not have the Android Market, and so get to invent their own strings. Reputedly, the ANDROID_ID value comes from the Market on first use. ANDROID_ID is fine for casual use, but it's not exactly the Rock of Gibraltar, if you know what I mean. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy _Beginning Android_ from Apress Now Available! -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
