The steps for HTTP traffic are typically much easier than HTTPS traffic, so a quick sanity check here makes sure that your proxy is set up correctly and reachable by the device.

At this point, you should be able to browse to and see Burp’s welcome screen.

Execute adb reverse tcp:8080 tcp:8080 which sends all traffic received on :8080 to :8080.
