java - Mediaplayer 不播放来自 URL 的音频

Question

目前我正在 Android Studio 上开发我的简单媒体音频播放器，我正在尝试从 URL 播放声音，但出现错误，请检查下面的代码：

public class MainActivity extends AppCompatActivity {

    public MediaPlayer mediaPlayer;
    Handler handler;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        handler = new Handler();
        final Runnable r = new Runnable() {
            public void run() {
                initAudio(getApplicationContext(), "http://ntcdn.stream/audio/teste.ogg");
                handler.postDelayed(this, 1000);
            }
        };
        handler.postDelayed(r, 1000);

    }

    public void initAudio(final Context context, String url) {
        if (mediaPlayer == null) {
            try {
                mediaPlayer = new MediaPlayer();
                mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
                mediaPlayer = MediaPlayer.create(context, Uri.parse(url));
                mediaPlayer.start();
            } catch (Exception e) {
                e.printStackTrace();
                Toast.makeText(context, "Falha ao iniciar o áudio", Toast.LENGTH_LONG).show();
                killMediaPlayer();
            }
        }
    }


    public void killMediaPlayer() {
        if (mediaPlayer != null) {
            try {
                mediaPlayer.reset();
                mediaPlayer.release();
                mediaPlayer = null;
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }

我想创建一个循环来始终播放音频，但是我从 logcat 收到了这个错误：

你能帮助我吗？我真的不知道我应该怎么做才能解决这个问题。

用这个：

private void startPlaying() {
    mediaPlayer = new MediaPlayer();
    try {
        mediaPlayer.setDataSource(YOUR_URL);
        mediaPlayer.prepare();
    } catch (IOException ignored) {
    }
    mediaPlayer.start();
}
