package com.collabera.labs.sai;  import java.util.timer; import java.util.timertask;  import android.app.service; 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.ibinder; import android.util.log; import android.widget.toast;  public class simpleservice extends service {     timer mytimer;  @override public ibinder onbind(intent arg0) {     // todo auto-generated method stub     return null; }  @override public void oncreate() {     super.oncreate();     toast.maketext(this,"service created ...", toast.length_long).show();     mytimer = new timer();     mytimer.schedule(new timertask() {          @override         public void run() {             // todo auto-generated method stub             //getdata();             locationmanager mlocmanager = (locationmanager) getsystemservice(context.location_service);             locationlistener mloclistener = new mylocationlistener();             mlocmanager.requestlocationupdates(locationmanager.gps_provider, 0, 0,                     mloclistener);          }     },0,1000);  }  @override public void ondestroy() {     super.ondestroy();     toast.maketext(this, "service destroyed ...", toast.length_long).show(); } public void getdata() {  } public class mylocationlistener implements locationlistener {     @override     public void onlocationchanged(location loc) {         loc.getlatitude();         loc.getlongitude();         string text = "my current location is: " + "latitude = "                 + loc.getlatitude() + "longitude = " + loc.getlongitude();         /*toast.maketext(getapplicationcontext(), text, toast.length_short)                 .show();*/         log.d("tag", "starting..");     }      @override     public void onproviderdisabled(string provider) {         /*toast.maketext(getapplicationcontext(), "gps disabled",                 toast.length_short).show();*/     }      @override     public void onproviderenabled(string provider) {         /*toast.maketext(getapplicationcontext(), "gps enabled",                 toast.length_short).show();*/     }      @override     public void onstatuschanged(string provider, int status, bundle extras) {     } }/* end of class mylocationlistener */ } 

toast.maketext(this, "service destroyed ...", toast.length_long).show();

you can't modify ui non-ui thread. services never executed on ui thread. log instead of making toast.

hey, struggling bit determine exact cause of error has been popping in our release environment. there not seem dealing particular error on google. this error message getting: sqlstate[34000]: invalid cursor name: 7 error: portal "" not exist the error pops when using pdo prepared statements. this setup our release environment: pgpool 3.0.1 (the postgresql backend in streaming replication mode!) php 5.3.5 postgresql 9.0 edit: architecture 64bit. the same error not manifest in our test environment (edit: forgot mention, standard test environment uses postgresql 9.0 without pgpool). thus, led suspect pgpool @ least partly suspect. does know probable causes error are? edit: ok, here example of kind of code causes error. $sql = 'select * '; $sql .= 'from "mytable" "mystuff" '; $sql .= 'where "mytable"."status" = 1 '; $sql .= 'and "mytable"."mytableid" = :table...
