android 共支持三种快捷方式，
静态快捷方式动态快捷方式固定快捷方式
如果要把快捷方式创建到桌面 需要创建固定快捷方式 【官方文档】
代码如下:
ShortcutManager shortcutManager =context.getSystemService(ShortcutManager.class);if (shortcutManager.isRequestPinShortcutSupported()) {// Assumes there's already a shortcut with the ID "my-shortcut".// The shortcut must be enabled.ShortcutInfo pinShortcutInfo =new ShortcutInfo.Builder(context, "my-shortcut").build();// Create the PendingIntent object only if your app needs to be notified// that the user allowed the shortcut to be pinned. Note that, if the// pinning operation fails, your app isn't notified. We assume here that the// app has implemented a method called createShortcutResultIntent() that// returns a broadcast intent.Intent pinnedShortcutCallbackIntent =shortcutManager.createShortcutResultIntent(pinShortcutInfo);// Configure the intent so that your app's broadcast receiver gets// the callback successfully.For details, see PendingIntent.getBroadcast().PendingIntent successCallback = PendingIntent.getBroadcast(context, /* request code */ 0,pinnedShortcutCallbackIntent, /* flags */ 0);shortcutManager.requestPinShortcut(pinShortcutInfo,successCallback.getIntentSender());}
如果创建的时候报这个错
Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified
修改这行代码
PendingIntent successCallback = PendingIntent.getBroadcast(context, /* request code */ 0,pinnedShortcutCallbackIntent, /* flags */ 0);
为
PendingIntent successCallback = PendingIntent.getBroadcast(this, /* request code */ 0,pinnedShortcutCallbackIntent, /* flags */ PendingIntent.FLAG_IMMUTABLE);
