How to close the program in the upper left corner of nexus 4?

I usually hold down the notification in the notification bar directly, and two options, delete notification and application information, will pop up, which can be set in the application information. Another method is to click on the rightmost one of the three primary keys at the bottom of the interface, find the program to cancel the notification, and press and hold the application information to reset.

In ink weather, you usually start it yourself. Turn off self-startup first, and then try to set it up. After a few days, I found it boring and deleted the ink.
