MaterialColdStart

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. Shell-based SVG templates allow developers to adjust dimensions and generate assets for multiple device configurations. A temporary launch theme is applied in the manifest and then replaced with the normal application theme during activity creation. The repository was archived in 2021 and now serves primarily as a reference for this older Android startup technique.
