Set App Update Resumed Listener
This is an function which sets up a listener to retrieve Update Information in the event your application was paused and then resumed. The purpose of this function is to handle situations where an update was being downloaded and for some reason the download was paused halfway through or completed while your application was closed.
You should always set this listener up to check if the Update Availability was in a status of DEVELOPER_TRIGGERED_UPDATE_IN_PROGRESS to prompt the user to continue the update by Launching a Play Update Request.
You should also check if there is an already downloaded update ready to be installed in order to prompt the user to Install the Update.

You can simply click and drag this pin to create a custom event.
Example
