Problem when downloading a file

Here's the problem I'm facing : I try to download a file from a tomcat server using the following snipet of code

try
 {
   BufferedInputStream getit = new BufferedInputStream(new URL("http://192.168.2.180:8080/android.apk").openStream());
   FileOutputStream saveit = new FileOutputStream(path);
   BufferedOutputStream bout = new BufferedOutputStream(saveit,1024);
   byte data[] = new byte[1024];
   int readed = getit.read(data,0,1024);
   while(readed != -1)
    {
        bout.write(data,0,readed);
        readed = getit.read(data,0,1024);
    }
    bout.close();
    getit.close();
    saveit.close();
}
catch(Exception e)
{
   e.printStackTrace
}

The above works just fine when I run it on the emulator , but when I try to test it on my device it doesn't do anything , and ~50 sec later it throws a "socket timeout"exception at the line

 BufferedInputStream getit = new BufferedInputStream(new URL("http://192.168.2.180:8080/android.apk").openStream());

What is this happening and how can I fix it ?

here's the stacktrace

The problem comes from the port 8080, try with a default url like http://www.google.com. (default port = 80) It will work.

As Samuh said, check that you have access to the private ip. Also you should catch that timeout exception correctly, showing a dialog to the user or a Toast.

Remember that if you are willing to use 3g in your phone for you application, I would recommend increasing the timeout values using something like:

setConnectTimeout(CONNECT_TIMEOUT);
setReadTimeout(READ_TIMEOUT);
