Android: 无法创建 MediaPlayer

Question

我正在尝试运行一个简单的测试应用程序来从在线广播电台流式传输音乐，但我总是收到有关 MediaPlayer setDataSource() 方法的错误。这是日志：

08-26 11:33:42.268  17698-17698/com.example.bruno.radioteste D/MainActivity﹕ Attempt to play http://50.7.98.106:8398
08-26 11:33:42.268  17698-17698/com.example.bruno.radioteste E/MediaPlayer﹕ Unable to create media player
08-26 11:33:42.268  17698-17698/com.example.bruno.radioteste W/System.err﹕ java.io.IOException: setDataSource failed.: status=0x80000000
08-26 11:33:42.278  17698-17698/com.example.bruno.radioteste W/System.err﹕ at android.media.MediaPlayer._setDataSource(Native Method)

代码非常简单，根据我的搜索，它应该可以正常工作。布局的 xml:

<Button
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="BassDrive-http://50.7.98.106:8398"
    android:onClick="play" />

和 activity class:

 public class MainActivity extends AppCompatActivity implements MediaPlayer.OnPreparedListener {

private static final String TAG = MainActivity.class.getSimpleName();

private MediaPlayer player;
private boolean isPlaying = false;

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

    player = new MediaPlayer();
    player.setOnPreparedListener(this);
    player.setAudioStreamType(AudioManager.STREAM_MUSIC);
}

public void play(View view) {

    if(isPlaying) {
        player.stop();
        isPlaying = false;
    } else {

        try {

            String stationIp = ((Button)view).getText().toString().split("-")[1];
            Log.d(TAG, "Attempt to play " + stationIp);
            player.setDataSource(stationIp);
            player.prepareAsync();
            isPlaying = true;

        } catch(Exception e) {
            e.printStackTrace();
        }
    }

}

@Override
public void onPrepared(MediaPlayer mp) {
    Log.d(TAG, "Trying to start...");
    mp.start();
}

@Override
protected void onStop() {
    super.onStop();

    // clear media player
    player.stop();
    player.release();
    player = null;
}

有两种可能的情况，

您是否在清单中添加了此权限？

<uses-permission android:name="android.permission.INTERNET" />

如果是，则 android 无法解码您的流。要对此进行测试，您可以尝试其他流。例如，尝试 spotify 30 秒预览流 http://d318706lgtcm8e.cloudfront.net/mp3-preview/d9d8686acc79916d2db76abdaa2c18a594fed332
