Android Kotlin Fundamentals codelab: failed to pop the chooser

[black-pwq]

Describe the problem

in codelab Android fundamentals 02.3:Implicit intents, it says we can open another application using implicit intents. But after i implemented the two applications (suggested in the taks 5 in that lab), it failed to open the app that i implemented. However it always opens the default application (say, chrome when open a website), and i cannot see the chooser. I tested in both emulator and my own physical device, the results were same. I guess this is caused by the high API level i used, or something should be added in my manifest.

In which lesson and step of the codelab can this issue be found? Android fundamentals 02.3:Implicit intents, step 7(Task 5: Receive an implicit Intent)

How to reproduce? click the "open website" button
