I want to create a button which will be shown on top of all apps. something like this
as you can see, there is a button at top left corner. it can receive touch events and touch events can be received outside it by other apps.
I tried to use Theme.Translucent.NoTitleBar
to my activity but it does not helped. I also set size to my button to [100, 100] but other activity behind it can not receive touch events. I think that the problem is in activity's window. it's size does not equel activity's size.
any help please
UPD
solved
