媒体播放器应用程序中的多个声音崩溃

Question

• 我开发了一个app，里面有4个声音文件一起播放
• 第一个声音：
  • 按下下一个按钮 -第二声：
  • 上一次按下按钮时
• 第三声：
  • 播放项目的声音

• 第四声：

  • 播放项目（项目如何说话）

• 一切正常，直到用户快速回放和第四次，文本到语音引擎崩溃

MediaPlayer：错误 (-19, 0) android

• 我尝试重置媒体播放器，在下一个和上一个按钮中释放并停止，但在后退和第四次之后，项目声音仍然停止。

我做了什么：

public class A extends Activity {


    int imgArr[] = {R.drawable.a, R.drawable.b, R.drawable.c, R.drawable.d};
    int soundsrc[] = {R.raw.a, R.raw.b, R.raw.c, R.raw.d};
    String pro[] = new String[]{"a", "b", "c", "d"};
    ImageView iView;
    int count = 0;

    TextToSpeech txtToSpeech1;
    MediaPlayer mp;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(R.layout.activity_names);
        stopService(new Intent(this, PlayMusic.class));


        iView = (ImageView) findViewById(R.id.imageView5);
        iView.setImageResource(R.drawable.befora);
        txtToSpeech1 = new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {


            @Override
            public void onInit(int status) {
                if(status != TextToSpeech.ERROR) {
                    txtToSpeech1.setLanguage(Locale.UK);
                    txtToSpeech1.speak(pro[count], TextToSpeech.QUEUE_FLUSH, null);
                }
            }
        });

        Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            public void run() {
                aSounds();
            }
        }, 1000);




    }

    @Override
    public void onDestroy() {
        // Don't forget to shutdown!
        if (txtToSpeech1 != null) {
            txtToSpeech1.stop();
            txtToSpeech1.shutdown();
        }
        super.onDestroy();
    }

    public void onPause(){
        if(txtToSpeech1 !=null){
            txtToSpeech1.stop();
            txtToSpeech1.shutdown();
        }
        super.onPause();
    }

    public void aSounds() {
        mp = MediaPlayer.create(ANames.this, soundsrc[count]);
        mp.start();
    }


    public void forwardd(View v) {
        buttonSounds(R.raw.multimedia_button_click);
        if (count < imgArr.length && count >= 0) {
            count++;
            if (count == imgArr.length)
                count = 0;
            iView.setImageResource(imgArr[count]);

            if (txtToSpeech1.isSpeaking()) {
                Log.i("Tag", "Stop speaking");
                txtToSpeech1.stop();
            }

            txtToSpeech1.speak(pro[count], TextToSpeech.QUEUE_FLUSH, null);
            // Execute some code after 2 seconds have passed

            Handler handler = new Handler();
            handler.postDelayed(new Runnable() {
                public void run() {
                    aSounds();
                }
            }, 1000);


        }
    }

    public void backwardd(View v) {
        buttonSounds(R.raw.multimedia_button_click);

        if (count >= 0 && count < imgArr.length) {
            count--;
            if (count == -1) {
                count = imgArr.length - 1;
            }
            iView.setImageResource(imgArr[count]);
            txtToSpeech1.speak(pro[count], TextToSpeech.QUEUE_FLUSH, null);

            Handler handler = new Handler();
            handler.postDelayed(new Runnable() {
                public void run() {
                    aSounds();
                }
            }, 1000);


        }
    }

    public void onImageClick(View v) {
        txtToSpeech1.speak(pro[count], TextToSpeech.QUEUE_FLUSH, null);
        Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            public void run() {
                aSounds();
            }
        }, 1000);
    }

    public void home(View v) {
        buttonSounds(R.raw.multimedia_button_click);
        Intent ii = new Intent(ANames.this, PlayMusic.class);
        finish();
        startService(ii);
    }

    public void buttonSounds(int src) {
        mp = MediaPlayer.create(ANames.this, R.raw.multimedia_button_click);
        mp.start();
    }


}

--我一直在尝试，非常非常长

-- 在 Google 上尝试了几乎所有关于媒体播放器工作的堆栈溢出答案。

-- 还有如何在点击按钮时停止、释放、重置、启动媒体播放器，但对我没有任何作用..

-- 所以最后决定把问题放到stack-overflow寻求帮助

-- 衷心欢迎任何帮助，并在此先感谢

如果按钮播放 1-4 秒的声音效果。考虑使用SoundPool 类。据我所知，它应该用于那些东西。媒体播放器错误 LINK 和 LINK。似乎遇到错误 19 的人需要释放他正在播放的资源。
