Question

好的，所以我第一次使用SHOUTCast流，并且我被告知Android已经改变了它与ICS后音频的工作方式

所以，我尝试了一些在2.3和2.2上运行良好的代码，但是当我尝试在4.2.2上运行它时它没有播放，

这是我的MainActivity.java

package com.mooo.ajbiz11.ponyfeather;

import android.app.Activity;
import android.media.AudioManager;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;

public class MainActivity extends Activity implements
        MediaPlayer.OnCompletionListener, MediaPlayer.OnPreparedListener,
        MediaPlayer.OnErrorListener, MediaPlayer.OnBufferingUpdateListener {

    private String TAG = getClass().getSimpleName();
    private MediaPlayer mp = null;

    private Button play;
    private Button pause;
    private Button stop;

    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.activity_main);

        play = (Button) findViewById(R.id.play);
        pause = (Button) findViewById(R.id.pause);
        stop = (Button) findViewById(R.id.stop);

        play.setOnClickListener(new View.OnClickListener() {
            public void onClick(View view) {
                play();
            }
        });

        pause.setOnClickListener(new View.OnClickListener() {
            public void onClick(View view) {
                pause();
            }
        });

        stop.setOnClickListener(new View.OnClickListener() {
            public void onClick(View view) {
                stop();
            }
        });
    }

    private void play() {
        Uri myUri = Uri.parse("http://radio.ponyvillelive.com:8026/stream");
        try {
            if (mp == null) {
                this.mp = new MediaPlayer();
            } else {
                mp.stop();
                mp.reset();
            }
            mp.setDataSource(this, myUri); // Go to Initialized state
            mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
            mp.setOnPreparedListener(this);
            mp.setOnBufferingUpdateListener(this);

            mp.setOnErrorListener(this);
            mp.prepareAsync();

            Log.d(TAG, "LoadClip Done");
        } catch (Throwable t) {
            Log.d(TAG, t.toString());
        }
    }

    @Override
    public void onPrepared(MediaPlayer mp) {
        Log.d(TAG, "Stream is prepared");
        mp.start();
    }

    private void pause() {
        mp.pause();
    }

    private void stop() {
        mp.stop();

    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        stop();

    }

    public void onCompletion(MediaPlayer mp) {
        stop();
    }

    public boolean onError(MediaPlayer mp, int what, int extra) {
        StringBuilder sb = new StringBuilder();
        sb.append("Media Player Error: ");
        switch (what) {
            case MediaPlayer.MEDIA_ERROR_NOT_VALID_FOR_PROGRESSIVE_PLAYBACK:
                sb.append("Not Valid for Progressive Playback");
                break;
            case MediaPlayer.MEDIA_ERROR_SERVER_DIED:
                sb.append("Server Died");
                break;
            case MediaPlayer.MEDIA_ERROR_UNKNOWN:
                sb.append("Unknown");
                break;
            default:
                sb.append(" Non standard (");
                sb.append(what);
                sb.append(")");
        }
        sb.append(" (" + what + ") ");
        sb.append(extra);
        Log.e(TAG, sb.toString());
        return true;
    }

    public void onBufferingUpdate(MediaPlayer mp, int percent) {
        Log.d(TAG, "PlayerService onBufferingUpdate : " + percent + "%");
    }

}

这在Android 2.3中完美运行，并且是为2.2制作的，但我似乎无法理解4.0+中的新音频内容所以当我运行已编译的APK（我在Dropbox中签名时，签名我一无所获......

我对Android编程非常陌生，任何帮助/见解都会令人惊叹，但要保持温和......我对Java的理解只是基本的...

另外，我想从三个按钮切换到MediaController，但找不到文档

Answer 1

Pfft ...数字......在发布时运行了一个LogCat，注意到我错过了互联网许可......

代码完美无缺，只需要一个许可，它就像我的平板电脑上的黄油一样
