Androiud app crash on new Recognizer()

[CJure]

Hi, I am testing VOSK on Android and when instantiate Recognizer app crashes. I use following code:

private void startRecording() {
  try {
           Log.i("VOSK","START");
           StorageService.unpack(context, "model-en-us", "model",
                   (tempModel) -> {
                       model = tempModel;
                   },
                   (exception) -> Log.e("RECORD", "model load failed " + exception));
           Recognizer recognizer = new Recognizer(model, 16000.0f);
           SpeechService speechService = new SpeechService(recognizer, 16000.0f);
           speechService.startListening(new RecognitionListener() {
               @Override
               public void onPartialResult(String hypothesis) {
                   Log.i("VOSK", "PARTIAL RESULT: " + hypothesis);
               }

               @Override
               public void onResult(String hypothesis) {
                   Log.i("VOSK", "RESULT: " + hypothesis);

               }

               @Override
               public void onFinalResult(String hypothesis) {
                   Log.i("VOSK", "FINAL RESULT: " + hypothesis);

               }

               @Override
               public void onError(Exception exception) {
                   Log.e("VOSK", "ERROR RESULT: " + exception);

               }

               @Override
               public void onTimeout() {
                   Log.i("VOSK", "TIMEOUT");
               }
           });
       } catch (Exception e) {
           Log.e("VOSK", "Exception: " + e);
           throw new RuntimeException(e);
       }

Another question is it possible to feed existing audio file to VOSK and get text as response?

You need to wait for model initialization in unpack, now you try to use the model before it is initialized
