body: <p>I am using <a href="https://github.com/openid/AppAuth-Android" rel="nofollow noreferrer">App-Auth</a> Library for OAuth authentication in Android app, and my login is in inappbrowser which is opened in Customtab. Now I want to add client cert to app which help server to identify the app.</p>
  <p>Is there a way I can add the client cert  which is in the apps raw folder to the in app browser.</p>
  <p>I don't want my users to install client certificate manually. Just want to pass on my app's client certificate to browser or added to cookie manager temporarily.</p>
