Correctly size the Android 12 splash screen

[mattleibow]

Description of Change

This PR make sure the splash image on Android 12+ fits withing the visible area. The image is still currently stretched and this will have to be fixed in another PR as this involves changing the rendering code, but for now if the source image is a square, then all is well.

Issues Fixed

Fixes #9794

NOTE: the splash image is still stretched because Android does not support an "aspect fill/fit", so we will have to do that ourselves. And the image is clipped on the corners because our image goes right to the end of the image, and it is being rendered in a circle.
To get a good splash screen image, make sure the it is square and fits within a circle.

is this fixed yet? having the same problem

[fgiacomelli]

Same problem for me, I tried the solution suggested in #9794 from @mattleibow but it lacks some informations:

• where do we have to place the file used as main image (the one you write as "name_of_your_splash_image") and what are the build action that we have to set?
• what is the build action that we have to use for the \maui_splash.xml file?

please if your workaround really works with Android 12 provide us a detailed and working sample because I tested with a lot of combinations and none works.

Still seeing this using .NET 7.0.102 :(

[mattleibow]

What are you seeing @mhrastegari? This PR is about the aspect ratio of the image. You may be seeing the new feature of Android to not support the full screen splash. They only support "icons" now. See also #7404

Please open a new issue with a screenshot if it is not the new, small circle splash format from Google. We can't really do anything. Probably in the next android they will change again, so best we can do is hope they un-decide to make this horrible decision.
