android text to speech 0 supported languages on nexus 7 -

i'm working on little app gives user option "speak" couple of commands app respond.

i've got speech recognition working , commands registered. being recognized , means, answer should played.

only issue is: doesn't.

here's bit of code use determine languages supported google's tts engine (i'm developing older version of android "tts.getavailablelangues()" isn't in there unfortunately):

locale[] locales = locale.getavailablelocales();     list<locale> localelist = new arraylist<locale>();     (locale locale : locales) {         int res = speaker.islanguageavailable(locale);         if (res == texttospeech.lang_country_available) {             log.d(tag, "language: " + locale);             localelist.add(locale);         }     }     log.d(tag, "languages available: " + localelist.size()); 

the output of last log always: "languages available: 0"

and indeed, if run bit of code:

int id = speaker.setlanguage(locale.english); checkid(id); 

it'll come "language not supported" error. odd, given i'm trying use 1 of default languages: english (uk, us, doesn't matter, it's "not supported").

so, obviously, when try run

speaker.getlanguage(); 

it returns null...

even stranger initlistener reports "texttospeech.success"

private oninitlistener listener = new oninitlistener() {      @override     public void oninit(int status) {         if (status == texttospeech.success) {             log.d(tag, "tts engine started succesfully");         } else if (status == texttospeech.error) {             log.d(tag, "seems error occured :c");         }      }  }; 

so log shows: "tts engine started succesfully".

and actual code use run tts:

public void speak(string text, context context, oninitlistener listener) {     string tag = "dashboardactivity";     log.d(tag, "speaking started in dummy module");     texttospeech speaker = new texttospeech(context, listener);      // int id = speaker.setlanguage(locale.uk);     int id = speaker.setlanguage(locale.english);      speaker.speak(text, texttospeech.queue_flush, null); } 

there doesn't seem wrong code, or missing something?

here's list of things i've tried/checked/installed:

• tts installed
• voice data installed (multiple voices uk , english)
• if press "listen example" button in settings works!

so, i'm sitting there's no reason shouldn't working. question then:

• am missing something? (special permissions? data?)
• why code tts engine supports 0 languages out of 400-something "locales"?
• how can fix this?

ok, fixed it. didn't think time tts engine needs initialize called "speak" right after instantiating it.

i moved oninit listener , presto: works!

here's oninitlistener now:

private oninitlistener listener = new oninitlistener() {      @override     public void oninit(int status) {         if (status == texttospeech.success) {             log.d(tag, "tts engine started succesfully");             log.d(tag, "setting language default");             int id = tts.setlanguage(locale.getdefault());             checkid(id);             tts.speak(mmessagetospeak, texttospeech.queue_flush, null);         } else if (status == texttospeech.error) {             log.d(tag, "seems error occured :c");         }      }  };
