Hi TAO,
Have you figured this out? I'm having the exact same problem.
I've tested my app on G1 (1.5), Nexus One (2.1), Droid (2.1), and EVO
(2.1).
The new API onSignalStrengthsChanged(SignalStrength signalStrength)
never got called on all 2.1 devices. But the funny part is the old API
onSignalStrengthChanged(int asu) worked correctly on Nexus One, but
not on Droid or EVO.
Please let me know if you are able to fix this problem.
Thanks.
