AutofillClientController leaking activity: system leak or is it my implementation?

Question

When rotating the emulator the memory leak below pops up. I'm not able to figure out exactly where it comes from. To me it looks like the systems AutofillClientController is leaking my ExampleActivity. Any thoughts are appreciated!

Tested on:

• Pixel 7 Pro API 34
• Pixel 4 API 31
• Pixel 3a API 28
• Pixel 4 API 21 (report is slightly different, but I think the cause is the same)
• LeakCanary 2.13

• CommonsWare: Agreed, that feels like a leak caused by the framework.
• keivan shamlu: it would be helpful if you can share the activity code please
