Android Marshmallow introduces black status icons for light colored themes
Android M will have a lot of cool new features, but one of the smaller ones Google didn’t mention was for app developers. Roman Nurik has revealed a new windowLightStatusBar flag that will tell the system to make icons and text in the status bar a translucent black color instead of the usual white.
This flag will be useful for apps which use light-colored tint for their status bar where white icons might be hard to read. It’s small, but developers who remain mindful of these small details tend to earn loyal userbases, so be sure to use it if your app needs it!
