The top-most window in Z order that wants input focus gets it. The window manager implements a simple policy for Z ordering. The parts of interest here are: 1. All windows associated with activities at the bottom, ordered by the global activity stack. 2. Toasts (which can't get input focus). 3. Status bar elements. 4. System dialogs (like crash / ANR dialogs). 5. Lock screen and its UI elements. Thus if your activity is resumed, it is at the top of the stack, and if it asks for input focus it will take it from all other activities since those are below it. However windows can still be on top of it, which can take input focus away from it.
