我正在尝试开发一个无线流应用程序使用服务，使它在后台播放。我用过前台、wakelock和wifilock，但我注意到收音机在20-30分钟后停止播放。我使用了电池优化和不同的链接，但问题仍然存在。请看一下我的代码，告诉我我做错了什么。我对此进行了一些研究，但没有找到解决办法。代码是在androidstudio上用java编写的，我已经在galaxys8和nexus5x上测试了这个应用程序。我的代码如下：

`My_code_in_MyService.jave_Section`

    MediaPlayer mediaPlayer;
    String url = "http://s28.myradiostream.com:11618/listen.mp3";
    ConnectionDetector connectionDetector;
    int Notification_ID =10;
    WifiManager wMgr;
    WifiManager.WifiLock wifiLock;

    public  MyService_8()
    {

    }

    @Override
    public void onCreate() {

        connectionDetector = new ConnectionDetector(this);
        mediaPlayer = new MediaPlayer();
        mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);

        try
        {
            mediaPlayer.setDataSource(url);
            mediaPlayer.prepareAsync();
            mediaPlayer.setWakeMode(getApplicationContext(), PowerManager.PARTIAL_WAKE_LOCK);
        }
        catch (IOException e)
        {
            Toast.makeText(MyService_8.this, "Something went wrong, please try again", Toast.LENGTH_SHORT).show();
        }
