So you do not want to click the button and pause the video, but do you want to open a full menu and let the video continue?
If you want to have a complete menu, as in the example n.2 of my library, but without pausing the video, the menu should be opened without starting any activity.
In the example number 2 the menu is linked to a transparent activity that pauses the video of the app under.
Actually, it is possible to have a complete floating menu without opening the activity, but I limited it to a single floating button.
At the moment I do not plan to change it, it would take time that I do not have available. But there are other libraries that you can find that do similar things,
@JordiCP and others I think of
@Informatix that are right for you. Search the forum for the word StandOut
