Android Text to speech And Speech to text

I am working with text to speech and speech to text at the same time. I am making an app in which it ask a question through text to speech and get the answer from the user through speech and app convert it to text. but it does not work fine. both are working at the same time like what it speak, it text it back. can we give some delay so that when it stop speaking then it listen for the voice and return that text.

}
else{
speakOut();
promptSpeechInput();
}
}else{
Toast.makeText(this, "Initialization failed", Toast.LENGTH_LONG).show();
}
}
}
`

Try changing:
speakOut();
promptSpeechInput();
to
promptSpeechInput();
And then add:
speakOut();
after
eText1.setText(result.get(0));
This should speak the text after it has finished getting the text
Edit: use this to determine when the speech is finished. When it is just call promptSpeechInput()

I think you would need to add
myTTS = new TextToSpeech(this, this);
in onCreate() of your activity. Hope this helps. That is where you are getting null. You have initialized in onActivityResult for later use. But it should be initialized prior to its use, too.`

In app-billing takes money but wont give product

When i call the purchase screen i can buy the in app product and everything works ok but when the user leave the app and returns to view the product it keeps asking them to buy again,
I need to know how i can make this so when the user purchases the app the store screen doesnt come up anymore and they can access the product, the app is designed so that when the user buys the app they gain access to a new activity with features built in
if anyone could help, I would be most grateful
I used this tutorial which was very helpful in getting me started:[TUT] Simple InApp Billing / Payment By blundell

You can check when the application starts by using restoreTransactions. If you have used Managed Products or Subscriptions then only you will get all the details of the user.
For Unmanaged product there is no detail maintained by google.
So call this in your main activity
mBillingService = new BillingService();
mBillingService.setContext(this);
mBillingService.restoreTransactions();
Once you call this in ResponseHandler class there is one method purchaseResponse
purchaseResponse(final Context context,
final PurchaseState purchaseState, final String productId,
final String orderId, final long purchaseTime,
final String developerPayload, final String purchaseToken) {
}
which will return all the details.
You can check purchaseState then after
if (purchaseState == PurchaseState.PURCHASED) {
} else if (purchaseState == PurchaseState.REFUNDED) {
} else if (purchaseState == PurchaseState.CANCELED) {
}

Cannot start TTS (Text to Speech)

Ok basically I have everything set up and I have set up my onClick method many times, but this time it is set up in my main.xml file
<Button
android:layout_alignParentRight="true"
android:layout_height="40dip"
android:layout_width="80dip"
android:id="#+id/speak"
android:enabled="true"
android:visible="true"
android:text="Speak" >
</Button>
obviously it has other things to define its layout but that is one of the xml layouts inside my button, and for some reason every time I click on the button, it just closes the entire application, Why is that?
also If I set it up to add a onClickListener then the button just does nothing.
I would set up my onClick listener like this
speak.setOnClickListener(this);
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.speak:
doSpeak();
break;
}
}
and it still doesnt work.... So i just dont know what I am doing wrong

I mean am i not setting the volume or setting or telling it to speak?!?!?, am I not telling it to do something it is supposed to do?..... the volume on my phone is on and the media volume is up, I have an HTC evo 4g so it should work.....

There are many things mixed up in your code, especially the part where you check the engine with a StartActivityforResult().
Please see this example of a working TTS: http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/TextToSpeechActivity.html
Also you did not assign any ID to the button (apparently?) Could it be, that another button is using the ID?
/edit:
First of all, merge both Activities. If you call onCreate()again, it will override the previous one. Then add implements OnClickListener and replace
speakBtn.setOnClickListener((OnClickListener) this);
with
speakBtn.setOnClickListener(this);
Eclipse will tell you that you need to add an unimplemented method.

If the XML code you copied at the top of your question is all you have to declare that button, then it is missing the id you expect (R.id.speak) in the handler...
I would suggest you add some debug prints in the doButton function see if that gets called correctly before going any further in the text-to-speech and so on.

If anyone can help or has a better way to run the code, I love to hear your ideals. I try to research but every way I try gave me a error or something. Thanks in advance.

Your button will not work until TextToSpeech calls onInit. So you should disable btnSpeak until then.

Your TTS stuff looks fine. However, I dont see where you are binding any button to your onClick method and neither does your Activity seem to implement the onClickListener interface. You would need to do one or the other to get that onClick method to run.
So basically, I dont see any way your onClick method will ever get called.
Assuming you have some view/button in your layout the user is supposed to click to hear the tts, I think you want something like:
Button btnSpeak = (Button)findViewById(R.id.btnSpeak);
btnSpeak.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
TextView textSpeak = (TextView) findViewById(R.id.mainText);
tts.speak(textSpeak.getText(), TextToSpeech.QUEUE_FLUSH, null);
}
});
