I may have found a problem in using the Wi-Fi Mac Address as a unique device id. If the Wi-Fi is turned off, I can detect that OK and ask the user to turn it on, provided I know that the device has Wi-Fi. I have been using PackageManager.hasSystemFeatures(PackageManager.FEATURE_WIFI) to determine this, and then resort to an inferior backup scheme in the rare cases where the devices does not have Wi-Fi capability. However I have evidence that some devices are returning FALSE even though they have Wi-Fi, if that Wi-Fi happens to be turned off. This evidence is only circumstantial based on the number of times my app has had to fall back to the inferior backup scheme for device id.
Can anyone confirm whether this is really true? If you boot up your device with Wi-Fi off, does PackageManager.hasSystemFeatures(PackageManager.FEATURE_WIFI) return FALSE? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
