[BUG] "Lawnchair Recent Apps" Crashes on Older Android Versions

[berkekbgz]

Describe the bug

Sometimes "Lawnchair Recent Apps" crashes when I try to access to recent apps using gesture controls.

Here's what I found:

In Line 255 of TopTaskTracker.java, Lawnchair tries to access isVisible method which introduced in Android 12. So I am thinking this is the reason why it is crashing on older Android.

https://github.com/LawnchairLauncher/lawnchair/blob/fb6fcb7a872c703bdd3fc8ca5430fca7ba000947/quickstep/src/com/android/quickstep/TopTaskTracker.java#L248-L260

I am not entirely sure on this since I don't have much experience in that side of Android development but I hope I could help.

Steps to reproduce

I didn't know it is happening because of an activity that is excluded from recents until I read the code and I don't know how to spawn that type of activity so I cannot reproduce it now. It is just happens randomly(?).

1. Find a way to summon an activity that is excluded from recents.
2. Using gesture controls swipe up to access recent apps
3. Go to 1 until it gives you a crash log

Expected behavior

It should not crash I think.
