How to delete Desktop shortcuts after the android program is uninstalled

My application will create a shortcut on the desktop when it is used for the first time. The code for creating a shortcut is as follows: my application will create a shortcut on the desktop when it is used for the first time. The code for creating a shortcut is as follows: my application will create a shortcut on the desktop when it is used for the first time. The code for creating a shortcut is as follows: when my program is used for the first time, a shortcut will be created on the desktop. The Code is as follows:

Java code

1. Intent intent = new intent ();
2. Intent. setclass (this, splashactivity. Class );
4. Intent addshortcut = new intent (action_add_shortcut );
5. Parcelable icon = intent. Reset cuticonresource. fromcontext (this,
6. R. drawable. Icon );
7. Addshortcut. putextra (intent. extra_shortcut_name, getstring (R. String. app_name ));
8. Addshortcut. putextra (intent. extra_shortcut_intent, intent );
9. Addshortcut. putextra ("DUPLICATE", 0 );
10. Addshortcut. putextra (intent. extra_shortcut_icon_resource, icon );
11. Sendbroadcast (addshortcut );

However, when the program is uninstalled, it does not delete the shortcuts on the desktop at the same time. This problem happened to me for a long time yesterday and is finally solved today. The solution is as follows:

Java code

1. Intent intent = new intent ();
2. Intent. setclass (this, splashactivity. Class );
3. Intent. setaction ("android. Intent. Action. Main ");
4. Intent. addcategory ("android. Intent. Category. launcher ");
6. Intent addshortcut = new intent (action_add_shortcut );
7. Parcelable icon = intent. Reset cuticonresource. fromcontext (this,
8. R. drawable. Icon );
9. Addshortcut. putextra (intent. extra_shortcut_name, getstring (R. String. app_name ));
10. Addshortcut. putextra (intent. extra_shortcut_intent, intent );
11. Addshortcut. putextra ("DUPLICATE", 0 );
12. Addshortcut. putextra (intent. extra_shortcut_icon_resource, icon );
13. Sendbroadcast (addshortcut );

However, when the program is uninstalled, it does not delete the shortcuts on the desktop at the same time. This problem happened to me for a long time yesterday and is finally solved today. The solution is as follows: that is, adding two filter attributes to intent.

Intent. setaction ("android. Intent. Action. Main ");

Intent. addcategory ("android. Intent. Category. launcher ");

In this way, the desktop icon will be bound to my application. After the application is uninstalled, the system will automatically delete the icon at the same time.
