The exception was thrown in the following code:
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Speech recognition demo");
startActivityForResult(intent, VOICE_RECOGNITION_REQUEST_CODE);.
I've googled and found that it's because of the voice search app from google is missing on the device I am using. and I could solve the problem by installing the app manually, but how could I get the apk installed programly, like import some library or other~
Thanks a lot.
