157239028: Firebase Dynamiclink not open my MAIN Activity and not receive newest link data

See original GitHub issue

[REQUIRED] Step 2: Describe your environment

Android Studio version: 3.5_
Firebase Component: Firebase Dynamic link
Component version: 19.0.0

[REQUIRED] Step 3: Describe the problem

Steps to reproduce:

I’m not a native speaker in English, sorry for my bad grammar 😓

I found that dynamic links might not open my app through the activity with action.MAIN tag when I click the link to my app after first time(which is completely fine). In this situation, neither the intent from onNewIntent with launchMode=singleTask nor normal getIntent with launchMode=standard returns the newest data from firebase but the previous one. However, if I clear the app from history before open it without dynamiclink, I can still get the latest missing data, which might be the same cause by issue #357

For example, if I have two dynamic links: link_a => https://example.page.link/url1 link_b => https://example.page.link/url2

I press link_a in social media -> open my app -> receive data inside link_a -> get back to social media and press link_b or link_a again -> open my app (not restart my MAIN activity) -> still receive data inside link_a until completely close the app -> completely close the app and launch app by icon (I should not get any link data) -> receive link_b data which I should get previous

When dynamic links run into not launch my app from MAIN activity for the first time, it won’t restart MAIN activity even if I use adb command or other ways to send intent until clear from history.
