Android app Add shortcut

Implementation principle: The use of intent, the code is as follows:

1 //Create a shortcut2     Private voidCreateShortcut () {3Intent shortcut =NewIntent ("Com.android.launcher.action.INSTALL_SHORTCUT"); 4 Shortcut.putextra (Intent.extra_shortcut_name, getString (r.string.app_name)); 5Intent Intent =NewIntent (Intent.action_main); 6 intent.addcategory (Intent.category_launcher); 7Intent.setclass ( This, Mainactivity.class);//set the first page8 Shortcut.putextra (intent.extra_shortcut_intent, Intent); 9Shortcuticonresource iconres = Intent.ShortcutIconResource.fromContext ( This, R.drawable.ic_launcher); Ten Shortcut.putextra (Intent.extra_shortcut_icon_resource, iconres);  One sendbroadcast (shortcut);  AToast.maketext (Getapplicationcontext (), "created successfully", Toast.length_short). Show (); -     }   -     //To interpret if a shortcut already exists the      Public Booleanisexistshortcut () { -         BooleanIsinstallshortcut =false;  -         FinalContentresolver cr = Mainactivity. This. Getcontentresolver ();  -         FinalString authority = "Com.android.launcher2.settings";  +         FinalUri Content_uri = Uri.parse ("content://" + Authority + "/favorites?notify=true");  -Cursor C = cr.query (Content_uri,NewString[] {"title", "Iconresource"}, "Title=?",NewString[] {getString (r.string.app_name)},NULL);  +         if(c! =NULL&& c.getcount () > 0) {   AIsinstallshortcut =true;  at         }   -         returnIsinstallshortcut;  -}

And then use the time:

1 if (Isexistshortcut ()) {2     Toast.maketext (Getapplicationcontext (), "Shortcut already exists", Toast.length_short). Show (); 3 }else{4    createshortcut (); 5 }

Remember to add permissions in the manifest file:

1     <uses-permission android:name= "Com.android.launcher.permission.INSTALL_SHORTCUT"/>2     < Uses-permission android:name= "Com.android.launcher.permission.READ_SETTINGS"/>3  < Uses-permission android:name= "Com.android.launcher.permission.WRITE_SETTINGS"/>
