In android, how do I add a desktop icon and delete an icon after uninstalling a program?

1: The create icon is as follows:

Intent intent = new Intent ();
Intent. setClass (this, SplashActivity. class );

Intent addShortcut = new Intent (ACTION_ADD_SHORTCUT );
Parcelable icon = Intent. Reset cuticonresource. fromContext (this,
R. drawable. icon );
AddShortcut. putExtra (Intent. EXTRA_SHORTCUT_NAME, getString (R. string. app_name ));
AddShortcut. putExtra (Intent. EXTRA_SHORTCUT_INTENT, intent );
AddShortcut. putExtra ("duplicate", 0 );
AddShortcut. putExtra (Intent. EXTRA_SHORTCUT_ICON_RESOURCE, icon );
SendBroadcast (addShortcut );

 

 

2: The delete icon is as follows:

Intent intent = new Intent ();
Intent. setClass (this, SplashActivity. class );
Intent. setAction ("android. intent. action. MAIN ");
Intent. addCategory ("android. intent. category. LAUNCHER ");

Intent addShortcut = new Intent (ACTION_ADD_SHORTCUT );
Parcelable icon = Intent. Reset cuticonresource. fromContext (this,
R. drawable. icon );
AddShortcut. putExtra (Intent. EXTRA_SHORTCUT_NAME, getString (R. string. app_name ));
AddShortcut. putExtra (Intent. EXTRA_SHORTCUT_INTENT, intent );
AddShortcut. putExtra ("duplicate", 0 );
AddShortcut. putExtra (Intent. EXTRA_SHORTCUT_ICON_RESOURCE, icon );
SendBroadcast (addShortcut );

Intent. setAction ("android. intent. action. MAIN ");

Intent. addCategory ("android. intent. category. LAUNCHER ");

Two filter attributes are required.
