shortcut function

Starting from Android N, Google Launcher has provided a shortcut function to facilitate users to use the functional services provided by the application faster (such as the picture below). When you pay every time We always have to open the app and find the payment button. Isn’t this more convenient?

Here we will explain in detail how third-party applications add and manage their own shortcuts. (Recommended Learning: PHPSTORM )

android has the authority requirements for ShortCut, not all Launcher can display the applicationcut. The explanation

Only the default launcher can access the shortcut information.

Only the desktop that is set as the default Launcher has the permission to obtain shortcut. How to let non-default desktops also obtain shortcut permissions? There is also a way, and we will study it later.

Static shortcut

Android supports static shutdown and dynamic shortcut. For dynamic shortcut, you don’t need to do any configuration in the manifest. For static one, you only need to declare meta. -data can

<meta-data android:name="android.app.shortcuts" android:resource="@xml/shortcuts"/>

Dynamic shortcut

framework provides ShortcutManager to manage shortcut. The method of obtaining ShortcutManager is as follows

mShortcutManager = mContext.getSystemService(ShortcutManager.class);

shortcut Update

If the user switches languages, how should shortcut be updated? Maybe you have already guessed that ShortcutManager must provide an updated interface. You need to re-obtain the resources and set them again, and finally call the following interface to update.

public boolean updateShortcuts(List<ShortcutInfo> shortcutInfoList) {
        ...
    }

The shortcut function provides a quick entry for applications. Applications can not only set static shortcuts, but also set dynamic shortcuts. They can also enable or disable shortcuts, and can also set shortcuts based on the user's usage behavior. Provide different shortcuts for different users.

The shortcut function requires the Android system SDK to be above 25. Unfortunately, domestic mobile phone manufacturers are slow to update and have not yet become widely popular. However, I believe that there will be a large number of applications providing this in the next two years. Function
