1.  Install root Mitm CA  cert

  - Installing the mitmproxy CA as a user certificate (via http://mitm.it)

   - In your AVD, go to Settings → Security → Advanced → Encryption & credentials → Trusted credentials. Find your certificate (default name is mitmproxy) in the list.

REF: https://docs.mitmproxy.org/stable/howto/install-system-trusted-ca-android/

NOTE: you will see chrome can proxy by mitmweb, but other apps don't. cause other apps don't use system certs.  so you should update app network security config.

2.  rebuild app with network_security_config.xml

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <base-config>
        <trust-anchors>
            <certificates src="system" />
            <certificates src="user" overridePins="true" />
        </trust-anchors>
    </base-config>
</network-security-config>

3.  add latency for app

# Optional per-host overrides (host -> (request_delay, response_delay))
# If a host is not listed here, defaults are used.
HOST_DELAY_MAP = {
    # "api.example.com": (0.05, 0.05),
    # "example.com": (0.5, 0.5),
