How do I use Android SpeechRecognizer as a service? -


i trying run android voice recognition service. can verify oncreate() , onstart() methods of service called, no callbacks speech recognition methods called, despite fact have set speechrecognizer object correctly. speech recognition seems work when done in activity instead of service. how make work service? manifest issue?

package net.viralpatel.android.speechtotextdemo;  import java.io.bufferedwriter; import java.io.filewriter; import java.io.ioexception; import java.util.arraylist;  import android.app.service; import android.content.intent; import android.os.bundle; import android.os.ibinder; import android.speech.recognitionlistener; import android.speech.recognizerintent; import android.speech.speechrecognizer; import android.util.log; import android.widget.toast;  public class myservice extends service implements recognitionlistener {     private speechrecognizer speechrecognizer;     @override     public ibinder onbind(intent arg0) {         return null;     }     @override     public void oncreate() {         toast.maketext(this, "my service created", toast.length_long).show();         log.d("tag", "oncreate");         speechrecognizer = speechrecognizer.createspeechrecognizer(getapplicationcontext());         speechrecognizer.setrecognitionlistener(this);          intent intent = new intent(recognizerintent.action_recognize_speech);         intent.putextra(recognizerintent.extra_language_model,                 recognizerintent.language_model_web_search);          speechrecognizer.startlistening(intent);      }      @override     public void ondestroy() {         toast.maketext(this, "my service stopped", toast.length_long).show();         log.d("tag", "ondestroy");     }      @override     public void onstart(intent intent, int startid) {         toast.maketext(this, "my service started", toast.length_long).show();         log.d("tag", "onstart");     }      @override      public void onbeginningofspeech() {       log.d("speech", "onbeginningofspeech");      }       @override      public void onbufferreceived(byte[] buffer) {       log.d("speech", "onbufferreceived");      }       @override      public void onendofspeech() {       log.d("speech", "onendofspeech");      }       @override      public void onerror(int error) {       log.d("speech", "onerror");      }       @override      public void onevent(int eventtype, bundle params) {       log.d("speech", "onevent");      }       @override      public void onpartialresults(bundle partialresults) {       log.d("speech", "onpartialresults");      }       @override      public void onreadyforspeech(bundle params) {       log.d("speech", "onreadyforspeech");      }       @override      public void onresults(bundle results) {       log.d("speech", "onresults");       arraylist strlist = results.getstringarraylist(speechrecognizer.results_recognition);       (int = 0; < strlist.size();i++ ) {        log.d("speech", "result=" + strlist.get(i));       }       bufferedwriter out;     try {         out = new bufferedwriter(new filewriter("mnt/sdcard/results.txt")); //        out.write(processor.execute(strlist.get(0).tostring()));           out.write("hello world");      } catch (ioexception e) {         log.e("speech",e.tostring());     }      }       @override      public void onrmschanged(float rmsdb) {       log.d("speech", "onrmschanged");      } }

there 2 things think need clarify , may provide workaround.

  1. have declared service in manifest properly? believe addressed.

  2. speech recognition may not start "oncreate" of service. had done similar implementation didn't work. can try placing startlistening(intent) in other method , call explicitly. worked me.

let me know if helps.

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
