Android Xamarin Forms set splash screen while xamarin forms initalizes

Just as the title says I'm looking for a way to basically hide the Xamarin Forms initialization process via a splash screen.
Currently I have the splash screen working as a separate activity that is the main launcher. Right now the splash screen is shown for 5 seconds then disappears. On faster devices this is not a problem but when I down clock the device to simulate slower devices the splash screen shows, then disappears leaving a black screen before the initialization process finishes showing the main screen.

Is there a way to launch the splash screen then have the XF initialization process signal that is finished and that the splash screen can be closed?

Any examples would be much appreciated.
