I have enabled DNS over https on Android P (it has built in system wide cpapbility) with Cloudflare. Problem is that I have no idea how to test if it is really working :-)

Install stubby on your mac or linux host. Ask the same questions on both. See what happens.

  Nice ! Didn't know about that. For a reference, this is what I get when I set my dns as 1dot1dot1dot1.cloudflare-dns.com on Android P: https://cloudflare-dns.com/help/#eyJpc0NmIjoiWWVzIiwiaXNEb3QiOiJZZXMiLCJpc0RvaCI6Ik5vIiwicmVzb2x2ZXJJcC0xLjEuMS4xIjoiWWVzIiwicmVzb2x2ZXJJcC0xLjAuMC4xIjoiWWVzIiwicmVzb2x2ZXJJcC0yNjA2OjQ3MDA6NDcwMDo6MTExMSI6Ik5vIiwicmVzb2x2ZXJJcC0yNjA2OjQ3MDA6NDcwMDo6MTAwMSI6Ik5vIiwiZGF0YWNlbnRlckxvY2F0aW9uIjoiWlJIIiwiaXNwTmFtZSI6IkNsb3VkZmxhcmUiLCJpc3BBc24iOiIxMzMzNSJ9 https://cloudflare-dns.com/help/#eyJpc0NmIjoiWWVzIiwiaXNEb3Q...

Intercept the traffic somewhere and inspect it with Wireshark. You can decrypt the HTTPS packets if you can manage to log the keys on Android (see https://jimshaver.net/2015/02/11/decrypting-tls-browser-traffic-with-wireshark-the-easy-way/ https://jimshaver.net/2015/02/11/decrypting-tls-browser-traf...).
