i have tried the following ,
package com.example.TextSpeaker;
import java.util.Locale;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.speech.tts.TextToSpeech;
import android.speech.tts.TextToSpeech.OnInitListener;
import android.util.Log;
import android.widget.Toast;
public class SpeakerService extends Service implements OnInitListener{
//Receiver rv = new Receiver();
//TextSpeaker tspker = new TextSpeaker();
public static TextToSpeech mtts;
@Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return null;
}
@Override
public void onCreate(){
//mtts =new TextToSpeech(getBaseContext(), null);
Log.d("SpeakerService","Service created successfully!");
mtts = new TextToSpeech(this,this);
mtts.setLanguage(Locale.ENGLISH);
//mtts.speak(rv.str, TextToSpeech.QUEUE_FLUSH,null);
//TextSpeaker.mtts.speak(Receiver.str,
TextToSpeech.QUEUE_FLUSH,null);
}
@Override
public void onStart(Intent intent,int startid)
{
Log.d("SpeakerService","Service started successfully!");
Log.d("SpeakerService","Service started successfully!");
//Log.d("SpeakerService","rv = " + rv.toString());
//Log.d("SpeakerService","tspker = " + tspker.toString());
Log.d("SpeakerService","tspker.mtts = " +
TextSpeaker.mtts.toString());
mtts = new TextToSpeech(this,this);
mtts.setLanguage(Locale.ENGLISH);
//TextSpeaker.mtts.speak("Service started",
TextToSpeech.QUEUE_FLUSH, null);
//TextSpeaker.mtts.speak(Receiver.str,
TextToSpeech.QUEUE_FLUSH,null);
mtts.speak(Receiver.str, TextToSpeech.QUEUE_FLUSH,null);
}
@Override
public void onDestroy(){
if(mtts!=null)
{
mtts.stop();
Toast.makeText(getApplicationContext(),"The service has
been
destroyed!", Toast.LENGTH_SHORT).show();
}
}
@Override
public void onInit(int arg0) {
// TODO Auto-generated method stub
}
}
Now i am not able to hear any sound. but only receive the Toast
messages. the logcat says "ERROR/MediaPlayerService(30): Couldn't open
fd for content://settings/system/notification_sound and also unable
to create media player""
