Class PlacelabExampleMidlet

java.lang.Object
  javax.microedition.midlet.MIDlet
      org.placelab.midp.demo.PlacelabExampleMidlet

All Implemented Interfaces:

javax.microedition.lcdui.CommandListener, EstimateListener, java.lang.Runnable, SpotterListener

public class PlacelabExampleMidlet

extends javax.microedition.midlet.MIDlet

implements javax.microedition.lcdui.CommandListener, SpotterListener, EstimateListener, java.lang.Runnable

This is an example MIDlet that uses the Place Lab daemon to obtain position estimates. The demo shows current GSM cell information, all nearby bluetooth devices, and a position estimate if available. As required by Place Lab, the map database needs to be populated with known beacons that can be seen in order to generate position estimates.
