无法从Android应用启动音频链接

Question

I'm trying to launch an intent from my application that will play audio from a streaming server. I've got a url for that stream and I'm using bit.ly to simplify the url to launch (I've tried without bit.ly and have the same results)

intent = new Intent( Intent.ACTION_VIEW, Uri.parse( "http://bit.ly/gKltQE" ) );
intent.setFlags( Intent.FLAG_ACTIVITY_NEW_TASK ); // i tried with and without this, no luck
startActivity( intent );

The browser starts, loads up the bit.ly link, redirects to the audio link then closes and returns to my app

When I launch the same bit.ly link in the browser manually, it works fine (launches the audio streaming app):

I've tried fiddling with various intent.setFlags parameters but to no avail. Maybe a permissions issue? Or something to do with how I'm calling startActivity?

Answer 1

Not a permissions issue, it's just the BrowserActivity ending prematurely, maybe because there's no current tab. Best thing to do is to give an extra clue to the Intent resolver that it's not actually the Browser that should be handling the data:

intent.setType("audio/mpeg");

No other flags are needed... Sound Player (or your media player of choice) will now handle it.
