You have an HttpResponse there, check it before you try to use the entity.

http://developer.android.com/reference/org/apache/http/HttpResponse.html

int code = response.getStatusLine().getStatusCode(); 
String message = response.getStatusLine().getReasonPhrase();

And here are the constants Apache uses for the codes (they’re standard HTTP, but since you’re using HttpClient you can refer to these to see if you got a response you expect, or not): http://developer.android.com/reference/org/apache/http/HttpStatus.html

If the request gets to the server and fails, the response will let you know (for “wrong url” such as not even resolving the host, the connection will timeout, but that’s not the error you’re getting). And, even after that, I believe you should still check that the entity is not null before you pass it to EntityUtils (if it is null, something else unexpected went wrong, bail out).

Here’s an example that should point you in the right direction (I would not recommend just copying/pasting it, but rather trying to understand it; this is a broad generalization, you may want to just check for standard OK responses, not redirects, and or your server side may be doing something non-standard, that depends on the server):

HttpResponse httpResponse = null;
  String response = null;
  String message = null;
  int code = -1;
  try {
     httpResponse = client.execute(request);
     code = httpResponse.getStatusLine().getStatusCode();
     message = httpResponse.getStatusLine().getReasonPhrase();

     Log.i("LOG_TAG", "HTTP response -- code:" + code + "  message:" + message);

     if (code >= 200 && code <= 399) {
        Log.v("LOG_TAG", "got valid HTTP response code (200-399) processing response entity");
        HttpEntity entity = httpResponse.getEntity();
        if (entity != null) {
           InputStream instream = null;
           try {
              instream = entity.getContent();
              // convert stream if gzip header present in response
              Header contentEncoding = httpResponse.getFirstHeader("Content-Encoding");
              if (contentEncoding != null && contentEncoding.getValue().equalsIgnoreCase("gzip")) {
                 instream = new GZIPInputStream(instream);
              }
              response = convertStreamToString(instream);
           } finally {
              if (instream != null) {
                 instream.close();
              }
           }
        }
     } else {
        // GOT SOME NON-VALID CODE, 404 (not found), 5xx (error), etc (log this, react to this, whatever, but you can't just use the "entity")
     }
  } catch (ClientProtocolException e) {
     throw new RuntimeException("ERROR:" + e.getMessage(), e);
  } catch (IOException e) {
     throw new RuntimeException("ERROR:" + e.getMessage(), e);
  } finally {
     // shutdown connections
     client.getConnectionManager().shutdown();
  }

In general an HTTP response code between 200 and 399 is a success or redirect, and 4xx, 5xx are errors. Here’s some more info on HTTP response codes in general: http://en.wikipedia.org/wiki/List_of_HTTP_status_codes
