title: get SignalStrength without Using PhoneStateListener onSignalStrengthchanged
body: <p>does anyone know how to get the signal strength without having to call the onSignalStrengthChanged.  The problem with onSignalStrengthchanged is that is it called when the signal strength changes and I need to get the value of signalstrength according to a different criteria. </p>
  
  <p>Thanks in advance.</p>
