Add two permissions First

<uses-permission android:name= "Com.android.launcher3.permission.READ_SETTINGS"/>
<uses-permission android:name= "Com.android.launcher3.permission.WRITE_SETTINGS"/>

These two are permissions to modify the desktop's database

You can't change it without adding it!

Get data directly from content providers,

Static arraylist<shortcutinfo> Getitemsinlocalcoordinates (context context) {arraylist<shortcutinfo> it        EMS = new arraylist<shortcutinfo> ();        Final Contentresolver cr = Context.getcontentresolver (); Cursor C = cr.query (LauncherSettings.Favorites.CONTENT_URI, new string[] {LauncherSettings.Favorites.ITEM_ TYPE, LauncherSettings.Favorites.CONTAINER, LauncherSettings.Favorites.SCREEN, LAUNCHERSETTINGS.FAVORITES.C ELLX, LauncherSettings.Favorites.CELLY, LauncherSettings.Favorites.SPANX, LauncherSettings.Favorites.SPANY        , launchersettings.favorites.title,launchersettings.favorites.intent}, NULL, NULL, NULL);        Final int itemtypeindex = C.getcolumnindexorthrow (LauncherSettings.Favorites.ITEM_TYPE);        Final int containerindex = C.getcolumnindexorthrow (LauncherSettings.Favorites.CONTAINER);        Final int screenindex = C.getcolumnindexorthrow (LauncherSettings.Favorites.SCREEN); Final int Cellxindex = C.getcolumnindexorthrow (LauncherSettings.Favorites.CELLX);        Final int cellyindex = C.getcolumnindexorthrow (LauncherSettings.Favorites.CELLY);        Final int spanxindex = C.getcolumnindexorthrow (LauncherSettings.Favorites.SPANX);        Final int spanyindex = C.getcolumnindexorthrow (LauncherSettings.Favorites.SPANY);        Final int titleindex = C.getcolumnindexorthrow (LauncherSettings.Favorites.TITLE);        Final int intenindex = C.getcolumnindexorthrow (LauncherSettings.Favorites.INTENT);                try {while (C.movetonext ()) {Shortcutinfo item = new Shortcutinfo ();                ITEM.CELLX = C.getint (Cellxindex);                item.celly = C.getint (Cellyindex);                Item.spanx = Math.max (1, C.getint (Spanxindex));                Item.spany = Math.max (1, C.getint (Spanyindex));                Item.container = C.getint (Containerindex);                Item.itemtype = C.getint (Itemtypeindex); Item.screenid = C.getint (Screenindex);                Item.title=c.getstring (Titleindex);                if (c.getstring (intenindex)!=null) {item.intent=new Intent (c.getstring (Intenindex));            } items.add (item);        }} catch (Exception e) {items.clear ();        } finally {c.close ();    } return items; }

Modify the content similarly by the URL to modify,

I will not write the code specifically.
