I have a solution to dismiss the ActionSheet from iOS using the RootViewController. But I am unable to crack this for Android as I don't see any class that can give me control on the ActionSheet.
The requirement is to close this action sheet (if it was opened) when the application goes to sleep mode. We bring up the login screen when it wakes up from sleep- but it also shows ActionSheet with the login page since it was not closed. We do not close the current page either, when app sleeps- we keep it in the background, on login we show the last active page again.
