[feat] add an optional splash screen spinner

[peterpeterparker]

[X] I would like to suggest a feature

Description

Cordova provide the ability optionally to display a spinner over the splash screen.

Reference: https://github.com/apache/cordova-plugin-splashscreen

  <preference name="ShowSplashScreenSpinner" value="false"/>

I personally found this option interesting because I kind of feel that without spinner, even if the app took only 2 seconds too boot, as a user you kind of ask yourself if something is happening or not

If I'm not mistaken, maybe I missed it in the documentation, but this isn't possible yet in Capacitor therefore I allow myself to just suggest this feature

p.s.: If that would not be possible, already answered or if it's a duplicate etc. plz accept my apologies in advance

Hi @peterpeterparker. You may be interested in animating your splash screen using #790 (android only). See an example of what it brings, or a simpler version.

Some info on AnimatedVectorDrawable:

• https://developer.android.com/reference/android/graphics/drawable/AnimatedVectorDrawable

How I do it:

• https://github.com/cabasvert/cabasvert/blob/master/packages/client/capacitor.config.json#L8
• https://github.com/cabasvert/cabasvert/tree/master/packages/client/android/app/src/main/res

Ask me if you need more info.

@ptitjes thx for the links and details, definitely interesting and I might use it at some point, really cool 👍

that being said, I think the idea of a spinner is still kind of not too bad. It would be good to have a solution for both iOS and android and a spinner could be applied on full size splash image
