TTS在某些设备上崩溃

Question

在某些设备上加载TTS时出现以下错误（我不知道它们是什么，因为它来自客户端的远程堆栈跟踪）。

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.droidprofessor.android.mmm/com.droidprofessor.android.mmm.ActivityGame}: android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.speech.tts.engine.CHECK_TTS_DATA }

和

在我之前的帖子（Getting Error when loading TTS）中，我按照描述进行了更改。我添加了以下

                PackageManager pm = getPackageManager();
                Intent installIntent = new Intent();
                installIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
                ResolveInfo resolveInfo = pm.resolveActivity( installIntent, PackageManager.MATCH_DEFAULT_ONLY );

                if( resolveInfo == null ) {
                   // Not able to find the activity which should be started for this intent
                    Toast.makeText(getApplicationContext(), R.string.unable_to_access_the_android_market, Toast.LENGTH_LONG).show();
                } else {
                   startActivity( installIntent );
                }

以下是TTS活动的完整来源

public abstract class ActivityTTS extends Activity implements OnInitListener {
    //TEXT TO SPEECH SERVICE
    public static final int CHECK_TTS_AVAILABILITY = 0;
    private static final String TAG = "ActivityTTS";
    private TextToSpeech mTts; //Text to speech library


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        //TTS Service
        Intent checkIntent = new Intent();
        checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
        startActivityForResult(checkIntent, CHECK_TTS_AVAILABILITY);
    }

    /**
     * For TTS
     */
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        try {
            if(Logging.DEBUG_LOG) Log.d(TAG, "TTS Response: "+requestCode);
            if (requestCode == CHECK_TTS_AVAILABILITY) {
                if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {

                    // success, create the TTS instance
                    mTts = new TextToSpeech(this, this);            

                } else {
                    // missing data, install it
                    Toast.makeText(getApplicationContext(), R.string.install_audio_data, Toast.LENGTH_LONG).show();

                    PackageManager pm = getPackageManager();
                    Intent installIntent = new Intent();
                    installIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
                    ResolveInfo resolveInfo = pm.resolveActivity( installIntent, PackageManager.MATCH_DEFAULT_ONLY );

                    if( resolveInfo == null ) {

                    } else {
                       startActivity( installIntent );
                    }

                    finish();
                }
            }
        }catch (Exception e) {
            if(Logging.ERROR_LOG) Log.e(TAG, "Unable to access service");
            finish();
        }

    }




    /**
     * Loads when the TTS is ready
     */
    @Override
    public void onInit(int status) {
        mTts.setLanguage(Locale.getDefault());
    }


    /**

    final void speak(String text) {
        try{
            mTts.stop(); //Stop speaking
            mTts.speak(text, TextToSpeech.QUEUE_FLUSH, null);
        }
        catch(Exception e) {
            if (Logging.ERROR_LOG) Log.e(TAG, "TTS Failed - cannot say: "+text );
        }

    }


    @Override
    protected void onDestroy() {
        super.onDestroy();

        //Close the Text to Speech Library
        if(mTts != null) mTts.shutdown(); 
    }
