Hi,
having the exact same problem on a Droid 2.0.1 and HTC Hero 1.5. :
String androidID = Secure.getString(this.getContextResolver(),
android.provider.Settings.Secure.ANDROID_ID);
Toast.makeText(this, "ANDROID_ID: " + androidID,
Toast.LENGTH_LONG).show();
consistently returns null on the devices and differences in OS and
device seem to indicate some sort of problem with the compiled code.
Not sure what is causing this, could be that the app erroneously
believes it is running on an emulator or for some other reason is
unable to retrieve the setting.
No uncaught exceptions or other error message are printed when making
these calls which help.
For our application to work we need to be 100% sure we have a unique
ID across all OS versions and device manufacturers, which is exactly
what androidID is for. We're using IMEI and some key voodoo to sort of
make it unique, but would prefer androidID to work. Also, it not
working may be caused by something else that is also breaking other
functionality.
Haven't found the cause yet, but as soon as something falls into place
I'll post it here. In the meantime, what is the name of the android
apps you're using? Would like to test with the exact same ones you're
testing on.
Thanks!
