Android:无法找到QCMediaPlayer

Question

我的媒体播放器有问题,因为我在我的lg-smartphone上将我的android -version更新为5.0.2.

我有一个独立的课程来播放音乐

public class MediaPlayerService {

    public static MediaPlayer mediaPlayer;
    private static SoundPool soundPool;
    public static boolean isplayingAudio = false;
    static int soundID;

    public static enum State {
        Stopped, 
        Playing, 
    }

    static State mState = State.Stopped;

    public static void playAudioFromMediaPlayer(Context c) {

        mediaPlayer = new MediaPlayer();
        mediaPlayer = MediaPlayer.create(c, R.raw.hooray);
        if (!mState.equals(State.Stopped)) {
                mediaPlayer.start();
                mState = State.Playing;
        }
    }

    @SuppressWarnings("deprecation")
    public static void loadAudioFromSoundPool(Context c, int id) {

        soundPool = new SoundPool(4, AudioManager.STREAM_MUSIC, 100);   
        soundID = soundPool.load(c, SoundList.soundList.get(id), 1);
    }

    public static void playAudioFromSoundPool() {

        soundPool.play(soundID, 1, 1, 0, 0, 1);
    }

    public static boolean isMediaPlayerPlaying() {
        if (mState.equals(State.Playing)) {
            return true;
        }
        return false;
    }

    public void releaseMediaPlayer() {
        if(mediaPlayer != null || mediaPlayer.isPlaying()) {    
            mediaPlayer.stop();
            mediaPlayer.release();
            mediaPlayer = null;
        }
    }       

    public void releaseSoundPool() {

    }
 }

我想在Mainactivity上播放声音文件

MediaPlayerService.playAudioFromMediaPlayer(getApplicationContext(), soundID);

但我成了以下日志消息:

使用soundpool它可以正常工作,但不适用于媒体播放器.这是什么原因,我该如何解决？

在此先感谢我的英语:)

我认为您的平台不支持使用 QCMediaPlayer 恐怕 - 这就是为什么它给您所有这些错误，您可以通过查看此来源找到更多信息：

如果我是你，我会暂时坚持使用 soundpool。
