Android媒体流错误? Java.io.FileNotFoundException:没有内容提供者:http://

我跟随 this 在Android中播放流广播

在这里工作正常,但单击后播放器加载位变慢,我需要等待30秒钟以上的时间

但是我在控制台中收到此错误

在链接中,您可以看到所有文件,例如 player

由于此错误,我的流很慢。请任何人帮助我这种类型

这是我尝试使用.ogg和Just.mp3/live文件导致的错误

http://www.example.com:8000/beet.ogg
http://www.example.com:8000/mouthorgan.mp3
http://www.example.com:8000/live

音频正在播放,但是出现此错误之后,它花费了大约30秒钟的时间。有时候,它花费的时间太长了。

请帮我解决这个问题

Whats Going On

Java.io.FileNotFoundException:没有内容提供者: 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。

似乎您的问题在于将数据源设置为mediaplayer。当您尝试播放 setDataSource 方法所需的没有上下文的URL或流时。

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。

        String url = getIntent().getStringExtra("url");
        if (!TextUtils.isEmpty(url))
            startMediaPlayer(url);

    }

    @Override

            String action = intent.getAction();
            if (MediaPlayerService.SERVICE_TO_ACTIVITY.equalsIgnoreCase(action)) {
                /*

                currentPlayerStatus = intent.getStringExtra(MediaPlayerService.PLAYER_STATUS_KEY);
                Log.e("Player Mode", "" + currentPlayerStatus);

转到此文件 https://github.com/Old-Geek/Radio/blob/master/app/src/main/Java/org/oucho/radio/Player.Java#L234 并更改

player.setDataSource(context, Uri.parse(url));

player.setDataSource(url)

问题是void setDataSource (String path)设置要使用的数据源(文件路径或http/rtsp URL)。

path字符串:文件的路径,或您要播放的流的http/rtsp URL

github代码使用void setDataSource (Context context, Uri uri),它假定uri具有某种形式的ContentProvider

context Context:解决Uri时要使用的Context
uri Uri:您要播放的数据的内容URI

在Android 9+上,净HTTP流量可能会导致此问题。请检查以下一项: Android 8:不允许使用明文HTTP流量
