Set the launchMode on the Activity in your manifest to be
singleTask. This will make it so that if an existing Activity exists when you try to launch it, it will find it and call its onNewIntent instead of creating a new instance.Please note that this will only work if the framework hasn't destroyed the old activity for resources yet. Which is unlikely if you quickly go back to that app, but can happen if you take a long time or open resource intensive apps.
