How to programmatically install a specific TTS engine in Android?

I’m trying to add a special TTS engine to my application - not based on the system, so each person will have a different one, but one for everyone.

There is a method in the documentation: setEngineByPackageName () , which looks like it will do what I want. However, looking at other similar problems earlier, I found something using this method: https://stackoverflow.com/questions/12549086/selecting-required-tts-programmatics-in-android .

It looks quite normal, but it is used after checking the system whether the TTS engine is installed and installing it if it is not (it is not determined which one).

@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    // Fire off an intent to check if a TTS engine is installed
    Intent checkIntent = new Intent();
    checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
    startActivityForResult(checkIntent, MY_DATA_CHECK_CODE);
}

public void onActivityResult(int requestCode, int resultCode, Intent data)
{
    if (requestCode == MY_DATA_CHECK_CODE)
    {
        if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS)
        {
            // success, create the TTS instance
            mTts = new TextToSpeech(this, this);
        }
        else
        {
            // missing data, install it
            Intent installIntent = new Intent();
            installIntent.setAction(
                    TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
            startActivity(installIntent);
        }
    }
}
