Is there any way to track what fragment/s are visible right now?

Question

I work on a very large project. It has a lot of modules and views - activities and fragments. I need to understand what fragment and what activity are running at the moment. Then I need to move to this class of activity and fragment in the project. Is there any way to find the class name? maybe by logs or smth else?

Answer 1

You can use Android Profiler for this. You will also get a lot of details from this tool. Just hover the mouse over the graph, it will show the fragment currently showing.

Answer 2

You can try Layout Inspector, a feature of android studio. When the app is running on a device that is connected to Android Studio, you can click on any item to see the view id, you can use these ids to find out which activity/fragment they belong to (through xml file)

Answer 3

Use UserVisibleHint for that:

boolean isVisible;

@Override
    public void setUserVisibleHint(boolean isVisibleToUser) {
        super.setUserVisibleHint(isVisibleToUser);
        isVisible = isVisibleToUser;
    }

When you want to check the visibility of the fragment, simply check it.

if (isVisible) {
      //Fragment is visible
    } else {
      //Fragment is not visible
    }
