Android Settings wallpapers and create desktop icons

Wrote a small demo that implements the logic of setting up wallpapers and creating desktop icons:

Creating a wallpaper is simpler, turning drawable into bitmap, and then directly using SetWallpaper on the line:

Bitmap Bitmap = Bitmapfactory.decoderesource (Main.this.getResources (), r.drawable.wallpaper);                try {                    Main.this.setWallpaper (bitmap);                } catch (IOException e) {                    e.printstacktrace ();                }

To create a desktop icon:

if (!hasshortcut ()) {                    addshortcut ();                } else {                    toast.maketext (main.this, "desktop icon already exists", toast.length_short). Show ();                }

To create and delete desktop icons:

/** * Create desktop icons for programs */private void Addshortcut () {Intent shortcut = new Intent ("Com.android.launcher.actio        N.install_shortcut "); Shortcut.putextra (Intent.extra_shortcut_name, getString (r.string.app_name));//The name of the shortcut Shortcut.putextra (" Duplicate ", false);        Duplicate creation of Intent shortcutintent = new Intent (intent.action_main) is not allowed;        Shortcutintent.setclassname (this, This.getclass (). GetName ());        Shortcut.putextra (Intent.extra_shortcut_intent, shortcutintent);        Icon Intent.shortcuticonresource iconres = Intent.ShortcutIconResource.fromContext (this, r.drawable.ic_launcher);        Shortcut.putextra (Intent.extra_shortcut_icon_resource, iconres);    Sendbroadcast (shortcut); }/** * Delete the app's desktop icon */private void Delshortcut () {Intent shortcut = new Intent ("Com.android.launcher. Action.        Uninstall_shortcut ");        Icon Name Shortcut.putextra (Intent.extra_shortcut_name, getString (r.string.app_name)); String APPCLThis.getpackagename () + "." + This.getlocalclassname ();        ComponentName comp = new ComponentName (This.getpackagename (), appclass);        Shortcut.putextra (Intent.extra_shortcut_intent, New Intent (Intent.action_main). SetComponent (comp));    Sendbroadcast (shortcut); }

Determine if the desktop icon already exists:

Private Boolean Hasshortcut () {        Boolean isinstallshortcut = false;        Final Contentresolver cr = Main.this.getContentResolver ();        Final String authority = "com.android.launcher.settings";        Final Uri Content_uri = Uri.parse ("content://" + Authority + "/favorites?notify=true");        Cursor C = cr.query (Content_uri, new string[]{"title", "Iconresource"}, "Title=?",                new string[]{ Main.this.getString (R.string.app_name). Trim ()}, null);        if (c! = null && c.getcount () > 0) {            isinstallshortcut = true;        }        return isinstallshortcut;    }
