I need someone who can built a special CountDownTimer in Android.
The CountDownTimer have to start after clicking a button (button in StartActivity and CountDownTimer in MainActivity ==> 2 XML).
The CountDownTimer stop automatically to each next Friday. It Means if I click the button on Monday at 8:45:32 PM, the CountDownTimer have to stop next Friday at 8:45:32 PM and redirect to StartActivtity.
The CountDownTimer shows remaining Day(s), Hours, Minutes and Seconds.
"I M P O R T A N T"
The payment is only at the End of project if the app works.
When the phone is turned off or the app is closed, the timer must work in the background.
