This is a simple plugin for Android which will set the window background color for you app's MainActivity to a color of your choice. This allows you to avoid the standard dark grey background which will flash for a second before your splash screen appears. Set the color to the same background as your splash screen for a smoother start-up effect.

You'll need to set your desired window background color while installing the plugin by supplying the WINDOW_BACKGROUND_COLOR variable. Set it to whatever you want, preferrably the same color as your splash screen.

cordova plugin add cordova-plugin-android-window-background --variable WINDOW_BACKGROUND_COLOR=#ff69b4 --save

Or install directly from this repo:

cordova plugin add https://github.com/winteragency/cordova-plugin-android-window-background.git --variable WINDOW_BACKGROUND_COLOR=#ff69b4 --save

• Android (cordova-android 7.0.0+)

A custom WINDOW_BACKGROUND_COLOR variable will be added to your app's config.xml after installation with the value you selected (provided you included the --save flag). You can change it whenever you want, but you'll need to remove and re-add the Android platform from your project in order for the change to go through.

<plugin name="cordova-plugin-window-background">
    <variable name="WINDOW_BACKGROUND_COLOR" value="#B4D455" />
</plugin>

To re-add the Android platform:

cordova platform remove android
cordova platform add android

• Set status bar and/or navigation bar color in the theme as well. The standard Cordova Status Bar plugin will set the status bar color only after the app has initalized, resulting in an ugly translucent status bar while the splash screen is showing.
• Allow an image background to be used as windowBackground? Perhaps set it to the same image as the splash screen automatically?
• Find a way to make changes to config.xml automatically update without having to re-add the platform.
