title: How to set mime type of custom zip file?
body: <p>In my application I have create zip file in SD Card and rename it to custom extension like </p>
  
  <blockquote>
    <p><strong>customzipfile.abc</strong></p>
  </blockquote>
  
  <p>I have already use below code in manifest file but it's not working for me. I have also refer related link but it's fail for me.</p>
  
  <pre><code>&lt;intent-filter&gt;
        &lt;action android:name="android.intent.action.VIEW" /&gt;
        &lt;category android:name="android.intent.category.DEFAULT" /&gt;
        &lt;data android:scheme="file" /&gt;
        &lt;data android:mimeType="*/*" /&gt;
        &lt;data android:pathPattern=".*\\.abc" /&gt;   
        &lt;data android:host="*" /&gt;
  &lt;/intent-filter&gt;
  </code></pre>
  
  <p>Whenever I trying to get mime type it return null</p>
  
  <pre><code> String fileExtension= MimeTypeMap.getFileExtensionFromUrl(selectedUri.toString());
   String mimeType= MimeTypeMap.getSingleton().getMimeTypeFromExtension(fileExtension);
  </code></pre>
  
  <p>I have to also store this file on Google Drive. Whenever I'm trying to get file list from drive, I can't get this file using IntentSender.</p>
  
  <pre><code>IntentSender intentSender = Drive.DriveApi
                     .newOpenFileActivityBuilder()
                     .setMimeType(new String[] { "application/abc" })
                     .build(getGoogleApiClient());
  </code></pre>
