Trying to pass audio file to VOSK, it's in wav format however it causes the application to crash . this is my code:

 private fun recognizeFile() {
            try {
                Log.i("recognizer1","trying recognizer")
                val rec = Recognizer(
                    model, 16000f, "[\"one zero zero zero one\", " +
                            "\"oh zero one two three four five six seven eight nine\", \"[unk]\"]"
                )
                Log.i("recognizer2","trying recognizer")
                val ais: InputStream = audioFileRecordedOuput.inputStream()
                Log.i("recognizer3","trying recognizer")
                if (ais.skip(44) != 44L) throw IOException("File too short")
                Log.i("recognizer4","trying recognizer")
                speechStreamService = SpeechStreamService(rec, ais, 16000F)
                Log.i("recognizer5","trying recognizer")
                speechStreamService.start(this)
                Log.i("recognizer6","trying recognizer")
            } catch (e: IOException) {
                Log.e("Recognizer file",e.stackTraceToString())
            }

    }

and this is the stacktrace:

The logs only show up to Log.i("recognizer1","trying recognizer") and then crashes.

You probably didn't add jna library as a dependency for your project.

On most phones it is included as a default I think, but some time it might be missing.

Thank you I added it when I checkout the sample app build gradle.

Adding

implementation group: 'net.java.dev.jna', name: 'jna', version: '5.10.0'

to my app's build.gradle fixed this issue for me!
