How can I add text to speak for Arabic in Android?

How can I use text to speak for Arabic in Android Java or Kotlin? I've tried using android.speech.tts.TextToSpeech but Arabic is unavailable.

Anyone know of any free API's I can use for Arabic text to speak?

Sorry for my question being unclear. Below in Kotlin is an example of what I am trying to do:

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)

    tts = TextToSpeech(view.context, TextToSpeech.OnInitListener { status ->
        if (status != TextToSpeech.ERROR) {
            val loc = Locale("ar")
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
                val voiceName = loc.toLanguageTag()
                val voice = Voice(voiceName, loc, Voice.QUALITY_HIGH, Voice.LATENCY_HIGH, false, null)
                tts?.voice = voice
            }
            else {
                tts?.language = loc
            }

            //tts?.language = Locale.Arabic
        }
    })
    tts_button.setOnClickListener {
        val toSpeak = "As-salamu alaykum"
        //val toSpeak = "السلام عليكم"

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            tts?.speak(toSpeak, TextToSpeech.QUEUE_FLUSH, null, null)
        }
        else {
            tts?.speak(toSpeak, TextToSpeech.QUEUE_FLUSH, null)
        }
    }
}

Google's API clearly does not support Arabic. Anyone know of a different free API or library I can use instead that supports Arabic?

If you still think my question is unclear, please leave a comment and I will attempt to clarify further what I mean.
