  </code></pre>
  
  <p>while debugging the code reaches up to:</p>
  
  <pre><code>httpPost.setEntity(entity);
  </code></pre>
  
  <p>and it shows exception after this line ie on this statement:</p>
  
  <pre><code>HttpResponse response = httpClient.execute(httpPost, localContext);
  </code></pre>
  
  <p>Could any one help me on this?</p>
