I want to change the color of the status bar, the background color of the splash screen, or the color of the loading sign in Android.

Open colors.xml file to edit colors of the status bar, splash screen, and loading sign/loading indicator (image: https://www.webviewgold.com/docs/android/assets/img/screenshot_colors.png). Moreover, you can choose a light or dark theme of text color in the Config.java file: Check out the darkStatusBarText variable; set the variable to true for dark status bar text.
