close an activity after some time
I'm trying to make a dice rolling app and I want to run an activity which
displays an image of the result when a button is pressed and close it
after a few seconds. So how can I do this?
Maybe there's another way to display an image on top of my activity
without calling a new activity? I'm not sure.
I've read some things about timers but I don't really get it. And I know
people will tell me to let the user tap to dismiss the window but for this
app I'm sure I want it gone automatically.
