On Xiaomi, Samsung, Sony Mobile: Numbers (number of unread messages) are displayed on the icon: This part of the code is found in QQ5.
Xiaomi has passed the test.
Samsung and Sony have no corresponding phones and no tests. Some may modify the code (judging which phone code is).
Test it, you can reply to the test results, thank you
1. Native system (native Launcher), you can only modify shortcuts, and there will be toast prompts when adding and deleting them.
2. Xiaomi, Samsung, Sony Mobile: Custom Launcher: The action to send the number of unread messages is already different.For details, you can look at the code. . .
Determine the phone code:
/***
* Add numbers to the shortcut to the application icon
* @param clazz started activity
* @param isShowNum Whether to display numbers
* @param num Number displayed: integer
* @param isStroke Whether to add borders
*
