title: Android WebView Post Request with Custom Headers
body: <p>I could see there are two separate methods in Android docs to post the data and add the headers.</p>
  
  <pre><code>For setting Headers
  public void loadUrl (String url, Map&lt;String, String&gt; additionalHttpHeaders)
  
  
  For setting Post Data
  public void postUrl (String url, byte[] postData)
  </code></pre>
  
  <p>But what I really required is to post the data along with headers. ( Means I want a single method which does both the task ? )</p>
  
  <p>Can somebody please help me out with that.</p>
  
  <p>Thanks :)</p>
