This is the tiny sample code for testing Firebase Dynamiclinks issue, which has more detail description below in Issue Description part.

The app only have two activities. MainActivity is declared <action android:name="android.intent.action.MAIN" /> and <category android:name="android.intent.category.LAUNCHER" /> to simulate the app's entry point such as "welcome page" or "launch transition". Every launching process should go into MainActivity, which handles incoming intent by Firebase SDK and pass the target link to RealHomePageActivity. RealHomePageActivity just get the target link and show it on screen.

firebase/firebase-android-sdk#982

If the app is NOT in histroy and open NOT by dynamic links, anything looks fine. But if the app is NOT in histroy and open by dynamic link, this link will be failed until clearing histroy, which "failed" means the open process not through the activity with <action android:name="android.intent.action.MAIN" /> tag and the data in getIntent() is still the old one.

With this app for example the flow will like:

• User open the app (not in history) by clicking FDL_Reddit which is target to website of Reddit
  -> you will see https://reddit.com on screen
  
• User leave the app (not destroy it, like click devices home button)
  
• User click the FDL_Google link
  -> you will see https://www.google.com on screen
  
• Doing step 2 (leave app) again and click FDL_Reddit
  -> you will see app is open not through MainActivity and still show https://www.google.com on screen
• Close app and clear the histroy then re-open NOT by dynamiclinks -> you will see https//reddit.com on screen, but it should be null because I'm not open it by dynamic links

With the same logic, if you first open by FDL_Twitter, then you click FDL_Reddit, FDL_Facebook, FDL_Google, FDL_Others, they are all re-launch the MainActivity and work find, just FDL_Twitter will never work again until clearing history.
