accessibility - Android Talkback announcement interrupted

I have activity A with recipes that opens activity B for more options for a recipe.
In activity B I'm doing an action (like adding to favorites) that finishes activity B.
When doing that action, I'm triggering a Talkback announcement so that the user knows the action has been completed successfully.
However, the announcement gets interrupted halfway through because activity B is finishing and Talkback starts announcing activity A instead.

How can I make sure that Talkback announcements are not interrupted? Is there any way to change the priority in the API (similar to live regions?)

I also tried adding a Toast, but the toast announcement gets interrupted as well...

Any suggestions?
Thanks!
