安卓设置动态图标

Question

我正在开发一个通知应用程序，我想知道当我收到一个像 Whatsapp 中发生的新通知时，是否有办法动态设置应用程序图标，图标顶部带有圆圈数字，谢谢:)

There is no such feature available in android OS itself. The notification badge and dynamic icon like in weather and calendar apps purely depends on the launcher app you are using. For example, Samsung can ship a Samsung calendar app on Samsung devices. Samsung's home screen on those same Samsung devices can have special rules for rendering an icon for Samsung's calendar app, rules that involve showing the day of the month. This is because Samsung wrote the home screen. Hope you understand the scenario.
