If you want to RE some android apps HTTP or even HTTPS, it's more straight-forward to use httptoolkit and frida. Might be a bit rough the first time you do it, but once its set up its a breeze. You can intercept calls and even modify etc
This is actually now built into HTTP Toolkit, so it's easier than it sounds - if you connect a rooted device, there's an "Android app with Frida" interception option that installs Frida and runs the scripts above for you against any given app on the device automatically.
