How to implement the Android icon Digital Corner label (Badgenumber)

http://blog.csdn.net/janice0529/article/details/44344169

Android system Xiaomi, Samsung, Sony mobile phone send desktop quick key reminder digital icon, in Android system, well-known does not support Badgenumber, although third-party control Badgeview can implement in-app digital reminders, but for system icons, In particular, the logo of the app is difficult to achieve digital signage, even the way the drawings are constantly modified, but this way is inherently flawed, very poor practicality. Fortunately, some ROM vendors offer private APIs, but they also make it difficult, and the API's disagreement means that the increase in code volume and compatibility issues are more pronounced.

We now come to realize the desktop logo or icon on the top right corner, first look at 2 pictures, the first one from the Internet, the second from the personal practice! (because the experimental conditions are limited, only to test millet (⊙o⊙) ..., interested students to test the other bar)

Okay, on the code.
