How to detect if network connection is down while downloading file using InputStream and FileOutputStream in android?

I am downloading a file and then writing it into sdcard using following code:

 HttpResponse response = httpClient.execute(request);
 HttpEntity entity = response.getEntity();
 InputStream is = entity.getContent();
 File file = new File(Environment.getExternalStorageDirectory()+"/MyProject/data");
 FileOutputStream fos = new FileOutputStream(file);
 int inByte;
 while((inByte = is.read()) != -1){ 
     fos.write(inByte);
     System.out.println("in while loop inByte: "+inByte);
 }
 fos.close();
 is.close();

Everything is working fine. Normally it takes 2 minutes to download file. If i take out network cable during downloading then seems like it stays in while loop forever. That code is in try catch block but i do not get any exception. Is there anyway to get out of that while loop when network cable is unplugged. Thanks in advance.

You should be able to solve this by setting the timeouts on the HttpClient - the socket is staying open in case the server has a delay in the response. You can simply tell it to not wait so long. See the timeout options here:
