title: Hyperlinks with non HTTP schema in GMAIL
body: <p>So I'm making mobile apps and want to do links to activate things in both iOS and Android using the same URL. I know how to do this already. my intent on android is something like : </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;category android:name="android.intent.category.BROWSABLE"/&gt;
                  &lt;data android:host="activity.action android:scheme="myapp"/&gt;
              &lt;/intent-filter&gt;
  </code></pre>
  
  <p>My problem is when I go to test this and want to do a hyperlink in an email myapp://activity.action is not recognized as a url in gmail on android and displays as plain text. is there a way to fix this? how do i get non standard schema recognized by gmail as a link? </p>
