I am creating an application that contains fragments inside tabs.In this, when I try to call the application for billing in the application, it gives me the error inserted below.
Here is the design for calling my fragments in the application.
CalendarUIActivity (FragmentActivity) -> CalendarUIMain (Fragment) -> When the user ask for more then InAppSubsricbe (DialogFragment) -> On click of OK of above dialog another dialog fragment got open with list of In-App Products which InAppProductsList(DialogFragment)
Now, when I click on the list of products from the “Dialog Fragment” Edit it redirects it method to main CalendarUIMain Fragment at that time, it gives me an error (as shown in the figure below) when opening the purchase screen on the market successfully. But when you click OK on the purchase screen, it disappears when the application is forcibly closed.
