推荐答案
java.io.FileNotFoundException:没有内容提供者: http://www.example.com:8000/live.ogg
java.io.FileNotFoundException: No content provider: http://www.example.com:8000/live.ogg
因为它会根据上下文尝试从设备contentprovider中加载为文件,所以您将其作为URL进行传递.
Because its trying load as a file from device contentprovider based on the context and you are passing as a URL.
似乎您的问题在于将数据源设置为mediaplayer.当您尝试播放
Seems your issue is in setting datasource to mediaplayer. As you are trying to play url or streaming which required to setDataSource method without context.
播放实时流媒体时,我遇到了同样的问题.下面的代码解决了我的问题.
I was facing same issue while playing live streaming. and below code resolved my issue.

出于测试目的,我在这里使用了两个网址
For testing purpose here i have used two urls
UPDATE PlayerActivity
UPDATE PlayerActivity
public class PlayerScreen extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.player);
startService(new Intent(this, MediaPlayerService.class));
/*
* To get url which is passing from the previous activity listitem click.
* If url which is pass from listitem click is not empty it will start player
* */
String url = getIntent().getStringExtra("url");
if (!TextUtils.isEmpty(url))
startMediaPlayer(url);
}
@Override
protected void onResume() {
super.onResume();
registerReceiver(receiverFromservice, new IntentFilter(MediaPlayerService.SERVICE_TO_ACTIVITY));
}
private String currentPlayerStatus = "N/A";
private BroadcastReceiver receiverFromservice = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (MediaPlayerService.SERVICE_TO_ACTIVITY.equalsIgnoreCase(action)) {
/*
* To get current status of player
* */
currentPlayerStatus = intent.getStringExtra(MediaPlayerService.PLAYER_STATUS_KEY);
Log.e("Player Mode", "" + currentPlayerStatus);
}
}
};
@Override
protected void onPause() {
super.onPause();
unregisterReceiver(receiverFromservice);
}
/**
* TO start media player.It will send broadcast to Service & from service player will start
*
* @param url
*/
public void startMediaPlayer(String url) {
Intent intent = new Intent();
intent.setAction(MediaPlayerService.BROADCAST_TO_SERVICE);
intent.putExtra(MediaPlayerService.PLAYER_FUNCTION_TYPE, MediaPlayerService.PLAY_MEDIA_PLAYER);
intent.putExtra(MediaPlayerService.PLAYER_TRACK_URL, url);
sendBroadcast(intent);
}
}
让我知道是否有事.
