Resuming an Android app Activity with launchmode singleTask

Overview

I have an Android app with two activities:

Activity A is an onboarding with intent-filter as MAIN, LAUNCHER and launchmode singleTask
Activity B is a WebView that took data from Activity A

On first load a user will onboard and then startActivity() takes them to Activity B with a finish(). ActivityB is technically the main activity view I want the user to be seeing from now on for the rest of the future. I do set preferences so that Activity A will segue to B on the next close/open.

Behavior

When the app is backgrounded and then resumed, Activity B refreshes the webpage each time. It appears the app goes through Activity A and then B which has a loadUrl(). Why does singleTask run through the entire app?

Not setting launchMode or using singleInstance results in Activity A being properly ignored and staying on Activity B. However I was using singleTask because of an unrelated Branch.io setup.

>But my console log still seems to show that Activity A does get run through but NOT Activity B. Can you explain this? – karandeep singh Feb 16 '18 at 20:39
Sorry to clarify: `singleTask` Results in both activities code being re-executed on resume. `singleInstance` Results in Activity A being executed but not Activity B – ericjam Feb 16 '18 at 20:57
are you trying to launch your app from launcher? – karandeep singh Feb 16 '18 at 21:00
From launcher, and upon app resume – ericjam Feb 22 '18 at 19:24
