Notification when user comes online in Viber
Is it somehow possible for a phone to notify me when a user comes online in Viber? I'm not talking about a notification that comes when a user install viber on his phone and you get a notification that your friend started using viber. I'm talking about when your friend is already a user, and then turns off viber or his phone, and than turn it back on. In that moment I'd like to receive notification. If there is no simple solution is there an API for Viber wchich can help me do that. Or can I write an app for it without API?
