Make splash screen icon show when opening the app from deep link by including item in themes.xml

[veronicatc]

When opening my cordova app from deep links, the Android splash screen icon doesn't show.

I found out this is by design in Android, and to have it show, I need to add this to the theme style:

<item name="android:windowSplashScreenBehavior">icon_preferred</item>

How can I add this to the themes.xml file that is dynamically created by cordova cli when I compile the app?

Android documentation https://developer.android.com/develop/ui/views/launch/splash-screen#set-theme

Thanks!

Should be doable via the config-file directive.

Untested example:

<widget ... xmlns:android="http://schemas.android.com/apk/res/android">
   ...
   <platform name="android">
       ...
       <config-file target="themes.xml" parent="/resources/style">
           <item name="android:windowSplashScreenBehavior">icon_preferred</item>
       </config-file>
   </platform>
</widget

Couple of notes:

1. to use the android XML namespace, you need to add the xmlns:android attribute on the widget tag if you don't already have one.
2. the windowSplashScreenBehaviour setting is only honoured on API 33 or later. I'm not sure if it will cause issues on earlier devices.

Cordova should setup the files on the prepare command, so you can use cordova prepare android to test, then take a look at /platforms/android/app/src/main/res/values/themes.xml to make sure you're augmentation was taken. Prepare is implicitly ran on build & run as well.

Because this doesn't describe a bug I'm also going to transfer this to the main cordova repo as a discussion.
