　　 Public Static Final String action_add_shortcut = "Com.android.launcher.action.INSTALL_SHORTCUT";

    Private voidaddshortcut (String name) {Intent addshortcutintent=NewIntent (action_add_shortcut); //do not allow duplicate creationAddshortcutintent.putextra ("Duplicate",false);//The test is not repeated according to the name of the shortcut.//should be based on the intent of the fast chain to determine whether duplicate, that is, the value of the Intent.extra_shortcut_intent field//but the name is not the same, although some phone system will show a toast prompt repeat, will still establish a fast chain//prompt when there is no space on the screen//Note: Duplicate creation behavior MIUI and Samsung phones are not the same, millet on the seemingly can't repeat create shortcut//nameAddshortcutintent.putextra (Intent.extra_shortcut_name, NAME); //iconsAddshortcutintent.putextra (Intent.extra_shortcut_icon_resource, Intent.ShortcutIconResource.fro Mcontext (mainactivity.

This, Mainactivity.class);        Launcherintent.addcategory (Intent.category_launcher);        Addshortcutintent. PutExtra (Intent.extra_shortcut_intent, launcherintent); //Send broadcastSendbroadcast (addshortcutintent); }
