Hello. How can i close telephone screen with app like sleeping. Should i use activity starter.
Is there anybody to answer?
there are many. Please clarify your question and tell whether and what you have already tried.
As far as I know, this is not possible.
But you can set the background of the screen to black and all visible components (except one, for undo) to invisible.
Thanks a lot. I want to do that. When the children get their parents phone, after the minutes, the phone will be shut down.
