POAndroid onLocationChanged not called

Body
copied!<p>What do I need to do to get my LocationListener to fire it's onLocationChanged method?</p> <p>I am new to this stuff (java and android). Here is what I am doing. I handle a request for a location by calling context.startService(serviceIntent); Inside the intent service i have a nested class to act as the LocationListener in side the onHandleIntent method i start a thread which requests the location updates I maintain a reference to the LocationListener object and the tread in the the OnHandleIntent method.</p> <p>my plan was for the onLocationChanged method to update a variable that i could check periodically to see if the update has been completed, then break out of loop and do something with the location.</p> <p>The problem is the onLocationChanged method never gets called. The LocationListener object is still valid right to the end of the onHandleIntent method. I can even call it directly and get the debug message that I am expecting. I am pretty sure that the DDMS is changing the location as I have printed it out in various debug logs and i see it changing.</p> <p>Here is the code:</p> <pre><code>package com.example.locationrequestreceiver; import android.app.IntentService; import android.content.Context; import android.content.Intent; import android.location.Location; import android.location.LocationListener; import android.location.LocationManager; import android.os.Bundle; import android.os.Looper; import android.util.Log; public class LocationRequestService extends IntentService { private LocationManager locationManager; public class UpdateHandler implements Runnable, LocationListener { @Override public void onLocationChanged(Location arg0) { Log.d("myStuff", "inside location changed"); } @Override public void onProviderEnabled(String provider) {} @Override public void onStatusChanged(String provider, int status, Bundle extras) {} @Override public void onProviderDisabled(String provider) {} @Override public void run() { // TODO Auto-generated method stub Looper.prepare(); Log.d("myStuff", "inside thread"); locationManager.requestLocationUpdates("gps", 0, 0, this); Log.d("myStuff", "run ending"); Looper.loop() // <--- this was the fix } } public LocationRequestService() { super("LocationRequrestService"); Log.d("myStuff", "inside the service"); } @Override protected void onHandleIntent(Intent arg0) { locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE); UpdateHandler update_handler = new UpdateHandler(); Thread update_handler_thread = new Thread(update_handler); Log.d("myStuff", "starting thread"); update_handler_thread.start(); for (int count = 0; count < 20; count++) { try { Thread.sleep(1000); } catch (InterruptedException ex) { Thread.currentThread().interrupt(); } } Location location = locationManager.getLastKnownLocation("gps"); update_handler.onLocationChanged(location); } } </code></pre>
