Question

我正在研究媒体播放器应用程序，当它说出Https mp3链接的IOException时遇到了这个问题，我写的媒体播放器在除4.4.2之外的所有平台上都运行得很好。在Kitkat上，每当我设置数据源时，它都会给我设置数据源IO异常。

这是我用来调用构造播放器并初始化其所有组件的方法。

private void constructPlayer(SermonDtoNew sermonDto) throws IOException {
    mPlayer = new MediaPlayer();
    if (sermonDto == null) {
        return;
    }
    int pos = this.sermonDto.url.lastIndexOf('/') + 1;
    String str = sermonDto.url.substring(0, pos) + Uri.encode(sermonDto.url.substring(pos));
    mPlayer.setDataSource(this, Uri.parse(str));

    mPlayer.prepareAsync();

    mPlayer.setOnInfoListener(this);
    mPlayer.setOnPreparedListener(this);
    mPlayer.setOnErrorListener(this);
    mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
    mPlayer.setWakeMode(getApplicationContext(), PowerManager.PARTIAL_WAKE_LOCK);
    mPlayer.setOnCompletionListener(this);

    if (currentVersionSupportLockScreenControls) {
//            RegisterRemoteClient();
    }

    aquireWifiLock();
    requestFocus();
}

任何帮助将不胜感激。这个相同的代码适用于marshmallow，棒棒糖和除android 4.4.2之外的其他平台。
