  <p>This code is downloading the image from a web source, but every time when "curl_easy_perform" method is called it gives the error code 6. I have checked this with different URL but still unsuccessful :( ...</p>
  
  <p>"android.permission.INTERNET" and "android.permission.WRITE_EXTERNAL_STORAGE" permissions already given in Manifest file.</p>
  
  <p>Any pointer to solve this will be a great help.</p>
