recording stream to mp3

[Tony fig]

Here is the code that i found on net and seems to be the right code but for some reason every time I run it, it keeps crashing on me and i have been searching the net alll day and i have't been able to solve it. here is the code

try {
                       URLConnection conn = new URL("http://50.7.70.58:8708").openConnection();

                        InputStream is = conn.getInputStream();

                   OutputStream outstream = new FileOutputStream(new File("/mnt/sdcard/Download/file.mp3"));
                   byte[] buffer = new byte[4096];
                   int len;
                   while ((len = is.read(buffer)) > 0) {
                      outstream.write(buffer, 0, len);
                   }
                   outstream.close();
                   } catch (IOException e) {
                       e.printStackTrace();
                   }


here is the err im getting

If that is the full stack trace, where is the reference to a line in your code?

[Ron McLeod]

It seems like there is a problem with your URL.  If you snoop the network traffic, you will see that the server drops the connection immediately.  I tried your code using a different endpoint (http://50.7.70.58:8838/live for example), and it did capture the stream to file, and I was able to play using VideoLAN.

[Tony fig]

I just tried it using 3 different urls but keeps crashing. isn't there a way have it reconnect if if drops?

Did you try the URL that I suggested?

Provide a stack trace so that we can see where it is failing.

[Tony fig]

I just tried the url you have posted and it still crashes. Im using android studio to test on. could that be the problem?

It's difficult to guess at what the problem might be without seeing the stack trace for the crash.

[Tony fig]

were do i find the stack trace

here is some more err

It looks like a NetworkOnMainThreadException was thrown because you are running a network operation on the main (UI) thread.  This is discouraged because it can make your application freeze and become unresponsive.

You should be running your code in a separate thread using AyncTask.

I don't know if it's the cause of the error, but you should check for >= 0 or != -1. 0 is a valid return value, which just means that nothing was available right now, but at a later time data may become available again. Only -1 has a special meaning here: the actual end of the stream.
