应用程序在主屏幕上创建多个快捷方式

Question

My main activity has the following code

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    …


    homescreenShortcut();
}

private void homescreenShortcut() {
    Intent shortcutIntent = new Intent();
    shortcutIntent.setClassName(this, this.getClass().getName());
    shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    shortcutIntent.addCategory(Intent.ACTION_PICK_ACTIVITY);
    Intent intent = new Intent();
    intent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
    intent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "MyApp");
    intent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE,
        Intent.ShortcutIconResource.fromContext(this, R.drawable.app_icon));

    intent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
    sendBroadcast(intent);
}

Every time I launch the app, it creates a new shortcut on the home screen. Is there a standard or simple way to make sure only one home icon is created?

I am thinking of uninstalling the previous (if any) and then (re)installing. But that seems like an overkill.

shortcutintent.putExtra("duplicate", false);
