Error in InputSreamReader with Http Connection

I am extening "AsyncTask" in class and running below code in run method using timer class its a continue task.

 HttpClient client = new DefaultHttpClient();
 HttpPost httpPost = new HttpPost(sche.URL);
 long startTime = System.currentTimeMillis();
 HttpResponse response = client.execute(httpPost);
 in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
 String extStorageDirectory = Environment.getExternalStorageDirectory().toString();
 File file = new File(extStorageDirectory+"/"+runInBackend.count+sche.file_name);
 **is=new InputStreamReader(response.getEntity().getContent());**
 long bytesRead = 0;
 long totalBytesRead 
 //long startTime = System.currentTimeMillis();

 while ((bytesRead = is.read())!=0) 
 {    开发者_StackOverflow
     totalBytesRead += bytesRead;
 }

it is printing the below Output in logCat lines continuously but when i remove

InputStreamReader line that is bolded its work fine can anyone why this is behaving

like this

Use org.apache.http.util.EntityUtils.toByteArray(final HttpEntity entity) to read byte array from the server response.

Another point - read it only once. In your code it looks like you are trying to do this twice.
