Android: App shortcut has to be recreated after update

Question

A weird thing is happening: I've published an update to google play. When users download the update the existing home screen shortcut disappears and the have to recreate it or on other devices, the shortcut stays on the homescreen, but when they press it, it says the refering app isn't there and then they have to delete that shortcut and recreate it.

Does anyone know why this is happening?

Answer 1

Well I've chosen another launcher activity.

This is why it isn't working anymore. The shortcut references a launcher Activity and since you changed it, the shortcut won't work anymore.
