android TTS install language if not exist

i Try to use JAPANESE language on my Android 4 device.

int value = tts.setLanguage(Locale.JAPANESE);

but value is -2.

this is my code for checking

protected void check(int requestCode, int resultCode, Intent data) {
        if (requestCode == 0) {
            switch (resultCode) {
            case TextToSpeech.Engine.CHECK_VOICE_DATA_PASS:
                tts = new TextToSpeech(this, this);
                break;
            case TextToSpeech.Engine.CHECK_VOICE_DATA_BAD_DATA:
            case TextToSpeech.Engine.CHECK_VOICE_DATA_MISSING_DATA:
            case TextToSpeech.Engine.CHECK_VOICE_DATA_MISSING_VOLUME:
                Intent installIntent = new Intent();
                installIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
                startActivity(installIntent);
                break;
            case TextToSpeech.Engine.CHECK_VOICE_DATA_FAIL:
            default:
                Log.e(TAG, "Got a failure. TTS not available");
            }

You start your method by testing result code is equal to 0 and then have a swith on result code value (which you already know is equal to 0):

    if (requestCode == 0) {
        switch (resultCode) {

As written in your code, if language is not installed tts will not be initialized and any further reference to it will crash you application.

You can see the correct way to do it in An introduction to Text-To-Speech in Android
