Android shortcuts 1-create shortcuts through applications

Android shortcuts are the most basic components on the desktop. It is used to directly start a component of an application.

In general, you can create a shortcut to change an application on the left side of the Launcher Application List by long-clicking the icon of an application. In addition, you can add shortcuts to the desktop in two ways:

1. Create an Intent in the application and notify Launcher to create a shortcut in the form of Broadcast.

2. register an IntentFilter that meets specific conditions for the application components, and then add a shortcut to start the component on the Launcher desktop.

The following describes how to add shortcuts to an application.
