Get Cell RSSI(Network Signal Strength) on Android

问题:

Is there any way to retrieve the current cellular Signal Strength (RSSI) on Android 1.5?

I know there's a way to listen for signal strength updates through the TelephonyManager, but this seems to only give a "state," not a numeric value.

Is using the RSSI field on a neighboring cell fairly accurate? I'm guessing not, but I'm running out of ideas.

TelephonyManager.listen with flag LISTEN_SIGNAL_STRENGTHS

It seems that there is some kind of API change between the Android Versions. The answer to this question should give you some points to look further into this.
