【问题描述】：
请查看我用于流式广播流的代码，它适用于一个 URL，但不适用于另一个。
这个有效：
Uri myUri = Uri.parse("http://fr3.ah.fm:9000/");
但不是这个：
Uri myUri = Uri.parse("http://someOtherURL");
SimpleMusicStream.java
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 SimpleMusicStream 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.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://fr3.ah.fm:9000/");
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 + "%");
}
}
main.xml：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<Button
android:text="Play"
android:id="@+id/play"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></Button>
<Button
android:text="Pause"
android:id="@+id/pause"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></Button>
<Button
android:text="Stop"
android:id="@+id/stop"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></Button>
</LinearLayout>
Log-cat 显示错误：
NuHTTPDataSource(33): Server did not give us the content length!
Media Player Error: Unknown (1) -2147483648
Media Player Error: Unknown (1) -1002
有人可以帮我解决吗？
编辑：
只是为了与大家分享，我们的current code works with Android 2.1 & minor versions, but not works with Android 2.2 or higher。
谢谢

基于一些快速的谷歌搜索，它的音频编码
audio/aacp也让其他人有些头疼。 -

你能和我分享一下 ShoutCast URL Streaming Andriod 的源代码吗？
