confused with BroadcastReceiver

Question

i have the following pgm which responds with a Toast with an incoming msg and also speaks out the received msg, however there seems to be no speech synthesis in background but i still can see the Toast though, so should i start a service from the onReceive method (don't know if that's possible) here and then in the startService method , write the speak method??

here's one of my pgms:

Receiver

package com.example.TextSpeaker;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.telephony.SmsMessage;
import android.util.Log;
import android.widget.Toast;

public class Receiver extends BroadcastReceiver{


public static String str;
@Override
public void onReceive(Context context, Intent intent) {
    Bundle bundle = intent.getExtras();
    Log.d("Receiver","Message received successfully");

    SmsMessage[] msgs = null;

    if(bundle!=null)
    {
        // retrive the sms received

        Object[] pdus = (Object[])bundle.get("pdus");
        msgs = new SmsMessage[pdus.length];
        for(int i=0;i<msgs.length;i++)
        {
            str="";
            msgs[i]=SmsMessage.createFromPdu((byte[]) pdus[i]);
            str+="Message From "+msgs[i].getOriginatingAddress()+".   ";
            str+="The message is "+msgs[i].getMessageBody().toString();
            //TextSpeaker.mtts.speak(Receiver.str, TextToSpeech.QUEUE_FLUSH,null);
            //str="";

        }
        Toast.makeText(context,str,Toast.LENGTH_LONG).show();
        TextSpeaker.mtts.speak(Receiver.str, TextToSpeech.QUEUE_FLUSH,null);

    }
}

}

Answer 1

Your idea about starting the service in onReceive() and handling the speech output in the service should work. I would do the same. But I'm rather new to android programming.

Answer 2

i tried the following but still i can only get the Toast but not the voice, again it's null synthesis shown in logcat :

Receiver

Intent serviceintent = new Intent();
        serviceintent.setAction(".SpeakerService");
     if(TextSpeaker.flag==1)
        {
            context.stopService(serviceintent);
        }
     else
     {
        context.startService(serviceintent);
        Toast.makeText(context,str,Toast.LENGTH_LONG).show();
        TextSpeaker.mtts.speak(Receiver.str, TextToSpeech.QUEUE_FLUSH,null);
     }

where the SpeakerService is

package com.example.TextSpeaker;

import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.speech.tts.TextToSpeech;
import android.util.Log;
import android.widget.Toast;


public class SpeakerService extends Service {

//Receiver rv = new Receiver();
//TextSpeaker tspker = new TextSpeaker();
//public TextToSpeech mtts;
@Override
public IBinder onBind(Intent arg0) {
    // TODO Auto-generated method stub
    return null;
}

@Override
public void onCreate(){

    Log.d("SpeakerService","Service created successfully!");


}
@Override
public void onStart(Intent intent,int startid)
{
    Log.d("SpeakerService","Service started successfully!");
    Log.d("SpeakerService","Service started successfully!");

    Log.d("SpeakerService","tspker.mtts = " + TextSpeaker.mtts.toString());
    TextSpeaker.mtts.speak(Receiver.str, TextToSpeech.QUEUE_FLUSH,null);
}
@Override
public void onDestroy(){
    if(TextSpeaker.mtts!=null)
    {
        TextSpeaker.mtts.stop();
        Toast.makeText(getApplicationContext(),"The service has been destroyed!", Toast.LENGTH_SHORT).show();
    }

}

}

Answer 3

Intent serviceintent = new Intent();
        serviceintent.setAction(".SpeakerService");

i guess using the following change in ur intent might help:

Intent serviceintent = new Intent(context, SpeakerService.class)

Answer 4

You need to give enough time for TTS service to start before you try to use it.
