There is popular github that works app icon badges for most Android devices. 有一个流行的github，适用于大多数Android设备的应用程序图标徽章。 Sure still some platform, some devices didn't support that. 当然，仍然有一些平台，某些设备不支持该平台。 But those libraries almost cover all of the devices that support app icon badges. 但是这些库几乎涵盖了所有支持应用程序图标徽章的设备。

So to your question, No. Because Android framework didn't define the app notification badges before.(I am not sure if Android default framework have it now. I've been search the keyword of BADGE_COUNT_UPDATE in the ASOP android7 and nothing found) So all those custom badges are made by device manufacturer framework developer. 因此，对您的问题，不是。因为Android框架以前没有定义应用程序通知徽章。（我不确定Android默认框架现在是否具有它。我一直在ASOP android7中搜索BADGE_COUNT_UPDATE的关键字，但未找到任何内容）因此，所有这些自定义徽章都是由设备制造商框架开发人员制作的。

To another question. 另一个问题。 I use keyword badge to search the ASOP source code and didn't find any noticeable part about app icon badges. 我使用关键字badge来搜索ASOP源代码，但未找到有关应用程序图标badge的任何明显部分。 And even there is one inbuilt framework method about this after certain version of android. 在某些版本的android之后，甚至还有一个内置的框架方法。 The framework still cannot cover all the devices before the certain version. 该框架仍然无法覆盖特定版本之前的所有设备。 So not quite sure what do you mean by confidential app , but using libraries is the first choice to cover most android devices based on the real situation like this. 因此，不太确定您所说的“ 机密应用”是什么意思，但基于这样的实际情况，使用库是覆盖大多数android设备的首选。
