I have the above error when I am using below url http://cdnbakmi.kaltura.com/p/672322/sp/67232200/raw/entry_id/0_281db5u2/version/0
but execute my application with out any errors when I am trying with sample url http://www.pocketjourney.com/downloads/pj/tutorials/audio.mp3
I write bellow code for my application
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.reset();
mediaPlayer.setDataSource(audioURL);
mediaPlayer.prepare(); // might take long! (for buffering, etc)
mediaPlayer.start();
please tell me is this problem with my coding or with providing url.
thanks in advance.
edit: I solve this problem by using this code
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setInstanceFollowRedirects(false);
String redirectUrl = conn.getHeaderField("Location");
I get the redirect url by using above code.
回答1:
When it's not working with one server (and working for another) it means the problem is with the server (response) and not in your app. Try those links in browser first.
The failing link is redirecting to another URL that is actual MP3 URL. So you need to connect to the URL and get the response that may contain the actual mp3 URL.
I think this get the new URL.
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.getURL()// should give you the new URL dynamically created by server.
