使用 Media 在 Android 中使用 URL 播放媒体

Play Media using URL in Android using Media

我正在尝试使用 Media Player 播放 URL 中的音乐,但播放时出现错误

        final MediaPlayer mp = new MediaPlayer();
    try {

        mp.setDataSource(url[0]);
        mp.prepare();
        mp.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
            @Override
            public void onPrepared(MediaPlayer mediaPlayer) {
                mp.start();
            }
        });
    } catch(Exception e){
        System.out.println(e);
    }

我也试过使用 URI

        Uri uri = Uri.parse(url[0]);
        mp.setDataSource(context,uri);
        mp.prepare();

并且还尝试使用 mp.prepareAsync();方法

但随后也会出现此类错误并且无法播放媒体

W/MediaPlayer: Couldn't open 
java.io.FileNotFoundException: No content provider: 
    at android.content.ContentResolver.openTypedAssetFileDescriptor(ContentResolver.java:1675)
    at android.content.ContentResolver.openAssetFileDescriptor(ContentResolver.java:1505)

也得到这个

W/AudioTrack: Use of stream types is deprecated for operations other than volume control
See the documentation of AudioTrack() for what to use instead with android.media.AudioAttributes to qualify your playback use case
V/AudioTrack: pause(2131): prior state:STATE_ACTIVE
I/System.out: java.io.FileNotFoundException: : open failed: ENOENT (No such file or directory)

尝试将 url 解析为 Uri.parse(url),这可能有效。

我遇到了同样的问题,这段代码解决了我的问题

我用另一个线程播放来自url的音乐...

    final Handler handler =new Handler();

    final Thread audioThread = new Thread(new Runnable() {
        @Override
        public void run() {
            final MediaPlayer mediaPlayer = new MediaPlayer();

            Uri myUri = Uri.parse(url[0]);
            try {
                mediaPlayer.setDataSource(context, myUri);
                mediaPlayer.prepare();
            } catch (IOException e) {
                e.printStackTrace();
            }

            handler.post(new Runnable() {
                @Override
                public void run() {
                    btnPlayPause.setOnClickListener(new View.OnClickListener() {
                        @Override
                        public void onClick(View view) {
                            if (mediaPlayer.isPlaying()) {
                                mediaPlayer.pause();
                            } else {
                                if (mediaPlayer.getCurrentPosition() > 0)
                                    mediaPlayer.seekTo(0);
                                mediaPlayer.start();
                            }
                        }
                    });
                }
            });
        }
    });

** url[0] 表示您的音乐 url 和 btnplaypause 是播放和暂停音频的按钮

希望这也能解决您的问题...
