I'm looking for the simplest way to have two activities displayed at once, so that one Activity always remains visible, and the other changes with user interaction.
In other words:
- I currently have code for a program with several Activities.
- The user can navigate between these activities.
- I want to add a new Activity that will always be visible alongside what I already have.
- When the user navigates from the current Activity to another one, this new "side Activity" will remain visible.
I've seen many different ideas for doing something similar, but haven't been able to adapt them to my needs.
Any help would be appreciated.
