Android Add, remove, and judge desktop shortcut icons

Ideas:

Launcher in order for the application to customize its own shortcut icons, a broadcastreceiver is registered to receive customized information for the shortcut icons sent by other applications. So we just need to construct the corresponding intent based on the broadcastreceiver and load our custom information, and finally call the Sendbroadcast method to create a shortcut icon.

Steps:

1. You must have permission to create a shortcut;
2. Create a shortcut for the broadcast of the Intent action setting Com.android.launcher.action.INSTALL_SHORTCUT
3. Remove the Intent action setting for the broadcast of the shortcut Com.android.launcher.action.UNINSTALL_SHORTCUT
4. Set the picture and name of the shortcut in the Intent;

The permissions you need to add are as follows:

<uses-permissionAndroid:name= "Com.android.launcher.permission.INSTALL_SHORTCUT"/>    <uses-permissionAndroid:name= "Com.android.launcher.permission.UNINSTALL_SHORTCUT"/>    <uses-permissionAndroid:name= "Com.android.launcher.permission.READ_SETTINGS"/>    <uses-permissionAndroid:name= "Com.android.launcher2.permission.READ_SETTINGS"/>    <uses-permissionAndroid:name= "Com.android.launcher3.permission.READ_SETTINGS"/>
