MediaPlayer在循环时抖动

Question

我想使用MediaPlayer循环播放曲目。我已将MediaPlayer对象设置为循环。问题是轨道完成并进入下一个循环，有明显的抖动/滞后。我怎么能避免这种情况？我目前使用this链接中提到的代码。我使用以下代码设置我的MediaPlayer实例。

private void setupMPLesson() {
    setVolumeControlStream(AudioManager.STREAM_MUSIC);

    mMPCurrPlayer = new MediaPlayer();
    mMPCurrPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
    try {
        mMPCurrPlayer.setDataSource(this, Uri.parse("android.resource://" + RESOURCES_PACKAGE +
                "/" + R.raw.sweep_up_down_wav));
        mMPCurrPlayer.prepare();
    } catch (IOException e) {
        Log.e(TAG, "Could not find the file:", e);
    }

    // Create the media player instance for the next iteration ...
    createNextMediaPlayer();

}

方法createNextMediaPlayer()如下：

private void createNextMediaPlayer() {
        mNextPlayer = new MediaPlayer();
        mNextPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
        try {
            mNextPlayer.setDataSource(this, Uri.parse("android.resource://" + RESOURCES_PACKAGE +
                    "/" + R.raw.sweep_up_down_wav));
        } catch (IOException e) {
            Log.e(TAG,"Could not find the file:", e);
        }

        mNextPlayer.setOnPreparedListener(this);
        mNextPlayer.prepareAsync();

        // setting the completion listener to the mMPCurrPlayer
        mMPCurrPlayer.setOnCompletionListener(this);
    } 

准备好mNextPlayer后，我会执行以下操作：

@Override
    public void onPrepared(MediaPlayer mp) {
        mMPCurrPlayer.setNextMediaPlayer(mNextPlayer);
    }

完成一个cloop后，我将OnCompletionListener实现为：

@Override
    public void onCompletion(MediaPlayer mp) {
        // Check if the mp completed playing the number of loops required ..
        // If the current loop is smaller than the number of set loops ..

        mCompletedLoops++;

        mp.release();

        // Assign the current mMPCurrPlayer to the created mNextPlayer for looping ..
        mMPCurrPlayer = mNextPlayer;
        // Create the next media player and make it ready for the next iteration ..
        createNextMediaPlayer();

        if (mCompletedLoops < mNumLoops) {
            return;
        }

        // stop the media player ..
        mMPCurrPlayer.pause();
}

我还跟踪当前循环并在我越过所需数量的循环后停止。
