1. Add an Emulator named `pixel5`, if you don't already have one

```
$ sdkmanager --install "system-images;android-29;google_apis;x86"
$ echo "no" | avdmanager --verbose create avd --force --name "pixel5" --device "pixel" --package "system-images;android-29;google_apis;x86" --tag "google_apis" --abi "x86"
```

2. Run an Emulator using Android Studio or from command line.

```

fun Challenge.commonEquals(other: Any?): Boolean {
  return other is Challenge &&
    other.scheme == scheme &&
    other.authParams == authParams
}

fun Challenge.commonHashCode(): Int {
  var result = 29
  result = 31 * result + scheme.hashCode()
  result = 31 * result + authParams.hashCode()
  return result
}

        H2_PRIOR_KNOWLEDGE.protocol -> H2_PRIOR_KNOWLEDGE
        HTTP_2.protocol -> HTTP_2
        SPDY_3.protocol -> SPDY_3
        QUIC.protocol -> QUIC
        else -> {
          // Support HTTP3 draft like h3-29
          if (protocol.startsWith(HTTP_3.protocol)) HTTP_3 else throw IOException("Unexpected protocol: $protocol")
        }
      }
    }
  }
