Android build installs without an icon in the app drawer

Iam having this weird issue. I made an empty android project. When I built it and installed on my phone, the app icon showed up normally like it should. Then I added the oculus integration asset to build the app for Gear VR. Now after building and installing, the app installs itself without an app icon. It works fine if launched through cable or immediately after installing, but you cannot launch it afterwards because there is no icon to press in the app drawer. I don't get it what is going on and why the icon dissapeares when using the oculus integration.

Thanks for any help.
