java - Android emulator, Finding mock user location coordinates. Having problems -

hey guys, i'm having trouble trying find user's longitude , location run program , set telnet command geo fix mock location. while emulator running, set mock coordinates emulator become unresponsive , have program fail in detecting input coordinates.

import android.app.activity; import android.content.context; import android.location.location; import android.location.locationlistener; import android.location.locationmanager; import android.location.locationprovider; import android.os.bundle; import android.widget.textview; import android.widget.toast;  public class lbsact extends activity{     /** called when activity first created. */     public double longitude;     public double latitude;     public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.main);         longitude = 0;         latitude = 0;         //creating listener , manager         locationmanager lmanager = (locationmanager) this.getsystemservice(context.location_service);          locationlistener createlisten = new locationlistener(){             @override             public void onlocationchanged(location location) {                 //longitude = location.getlongitude();                 //latitude = location.getlatitude();                 string printout1 = "my current location is: " + "latitude = " + location.getlatitude() +                 "longitude = " + location.getlongitude();                     toast.maketext(getapplicationcontext(),printout1,toast.length_long).show();              }             @override             public void onproviderdisabled(string provider) {                 toast.maketext(getapplicationcontext(), "gps disabled", toast.length_long).show();              }             @override             public void onproviderenabled(string provider) {                 toast.maketext(getapplicationcontext(), "gps enabled", toast.length_long).show();              }             @override             public void onstatuschanged(string provider, int status,                     bundle extras) {             }         };          //cant use network emulator, can use gps mock locations         //toast.maketext(getapplicationcontext(), "does work?", toast.length_long).show();         lmanager.requestlocationupdates( locationmanager.gps_provider, 0, 0, createlisten);     }  } 

first of all. i'm assuming have read following: http://developer.android.com/guide/topics/location/obtaining-user-location.html

since mentioned injecting mock location data. there couple other things try to, instance use kml file inject gps locations: http://developer.android.com/guide/developing/tools/ddms.html#emulator-control

but main thing should create logging messages can more accurately detect program failing. here's article on how setup logcat: http://www.droidnova.com/debugging-in-android-using-eclipse,541.html

i suggest sending text screen might not work application can crash before gets calls.

also, have tried debugging application through eclipse? break on crash , give location of app failing.

i'll update answer give more details on issue it's kind of hard see what's happening without stack trace or logging trace.
