AppLinker4Unity

AppLinker4Unity is a Unity Android plugin (AAR) that allows you to fetch list of installed applications on a device, get app icons, names and perform actions such as opening the app or navigating to its settings page — that you can use on your Unity UI.

I've use this on one of my repo Simple Launcher.
