Beware that if your app requests one of the hardware device identifiers (such as the WiFi MAC -address, the {@link android.os.Build#SERIAL} number, or the {@link -android.provider.Settings.Secure#ANDROID_ID} number), they will provide the same value for each +address or the {@link android.os.Build#SERIAL} number), they will provide the same value for each user because these identifiers are tied to the hardware and not the user. Not to mention the other problems these identifiers introduce as discussed in the Identifying -- cgit v1.1
