Speech Recongnition android.content.ActivityNotFoundException

[ulasoc]

Speech recognition displays "Android.content.ActivityNotFoundException" on Android Vitals screen. I think SR is not installed in some devices, does not support it, turns it into crashes. What is best way avoiding this crash?

Error Log:

android.content.ActivityNotFoundException:

The Code:

private void CeviriBaslat() {

       Intent i = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
   if (lang.equals("tur")){

       i.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "tr-Tr");
       i.putExtra(RecognizerIntent.EXTRA_PROMPT, "Haydi birşey söyle!");

   }

   if (lang.equals("eng")){

       i.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.ENGLISH
               .toString());
       i.putExtra(RecognizerIntent.EXTRA_PROMPT, "Lets say something!");

   }



   startActivityForResult(i, check);

It looks like you need to have an application installed which can handle speech recognition. If you don't then that exception is thrown

https://developer.android.com/reference/android/speech/RecognizerIntent.html#ACTION_RECOGNIZE_SPEECH

This page gives a bit more explanation about how to implement a speech recognition app

Thank you sir. How can I prevent crashes if user have not installed Sp , when exception is thrown that it turns into Android Vitals on Google Play Console as crash log? Is it enough to use Try and Catch exception with code? Do you have any idea?

Yes absolutely you must catch the exception if it occurs. See the answer below for a code example of how to do that
