The Android Desktop program provides the ability to add and remove desktop shortcuts and determine if a shortcut exists.

Just pass in the shortcut title, icon, and click on the shortcut to execute the app intent. The code is as follows:



1. Add desktop shortcuts to Android



/**

* Add desktop shortcuts to the current app

*

* @param CX

* @param appName

* Shortcut Name

*/

public static void Addshortcut (Context cx) {

Intent shortcut = new Intent ("Com.android.launcher.action.INSTALL_SHORTCUT");

Intent shortcutintent = Cx.getpackagemanager ()

. Getlaunchintentforpackage (Cx.getpackagename ());

Shortcut.putextra (Intent.extra_shortcut_intent, shortcutintent);

Get the current app name

String title = null;

try {

Final Packagemanager PM = Cx.getpackagemanager ();

title = Pm.getapplicationlabel (

Pm.getapplicationinfo (Cx.getpackagename (),

Packagemanager.get_meta_data). toString ();

} catch (Exception e) {

}

Shortcut name

Shortcut.putextra (Intent.extra_shortcut_name, title);

Duplicate creation is not allowed (not necessarily valid)

Shortcut.putextra ("duplicate", false);

Icon for shortcut

Parcelable Iconresource = Intent.ShortcutIconResource.fromContext (CX,

R.drawable.ic_launcher);

Shortcut.putextra (Intent.extra_shortcut_icon_resource, Iconresource);

Cx.sendbroadcast (shortcut);

}



2. Android Delete Desktop shortcut



/**

* Remove desktop shortcuts for the current app

*

* @param CX

*/

public static void Delshortcut (Context cx) {

Intent shortcut = new Intent (

"Com.android.launcher.action.UNINSTALL_SHORTCUT");

Get the current app name

String title = null;

try {

Final Packagemanager PM = Cx.getpackagemanager ();

title = Pm.getapplicationlabel (

Pm.getapplicationinfo (Cx.getpackagename (),

Packagemanager.get_meta_data). toString ();

} catch (Exception e) {

}

Shortcut name

Shortcut.putextra (Intent.extra_shortcut_name, title);

Intent shortcutintent = Cx.getpackagemanager ()

. Getlaunchintentforpackage (Cx.getpackagename ());

Shortcut.putextra (Intent.extra_shortcut_intent, shortcutintent);

Cx.sendbroadcast (shortcut);

}



3, Android to determine whether the app already exists desktop shortcut



/**

* Determine if a shortcut has been added to the desktop

*

* @param CX

* @param titlename

* Shortcut Name

* @return

*/

public static Boolean hasshortcut (Context cx) {

Boolean result = false;

Get the current app name

String title = null;

try {

Final Packagemanager PM = Cx.getpackagemanager ();

title = Pm.getapplicationlabel (

Pm.getapplicationinfo (Cx.getpackagename (),

Packagemanager.get_meta_data). toString ();

} catch (Exception e) {

}

Final String Uristr;

if (Android.os.Build.VERSION.SDK_INT < 8) {

Uristr = "Content://com.android.launcher.settings/favorites?notify=true";

} else {

Uristr = "Content://com.android.launcher2.settings/favorites?notify=true";

}

Final Uri Content_uri = Uri.parse (URISTR);

Final Cursor C = cx.getcontentresolver (). query (Content_uri, NULL,

"Title=?", new string[] {title}, NULL);

if (c! = null && c.getcount () > 0) {

result = true;

}

return result;

}
