the class PackageItemInfo method loadSafeLabel.

     * reasonable amount. This prevents a malicious party to influence UI
     * layout via the app label misleading the user into performing a
     * detrimental for them action. If the label is too long it will be
     * truncated and ellipsized at the end.
     *
     * @param pm A PackageManager from which the label can be loaded; usually
     * the PackageManager from which you originally retrieved this item
     * @return Returns a CharSequence containing the item's label. If the
     * item does not have a label, its name is returned.
