MaterialColdStart
Utilize the window background during cold start time to make your app
Material Cold Start is an Android technique and asset generator for improving the visual appearance of an application's cold-start period. It uses the activity window background to display an interface-like preview before the main activity finishes initializing. This avoids the blank flash that can otherwise appear around status bars, toolbars, and app bars. The project generates scalable nine-patch assets that can imitate a Material Design app shell during startup.
