我正在创建一个用于向 WhatsApp 添加自定义贴纸的 android 应用程序。我已按照此示例进行操作，但在向 WhatsApp 添加贴纸时，会显示错误对话框，并显示消息“此贴纸包存在问题，无法添加到 Whatsap”。我得到 onActivity 结果的验证错误是"fd must not be null"。我无法找到此错误的原因。在这种情况下，FD 是什么？
我尝试过的： -我尝试添加发布者电子邮件、网站等所有字段，但仍然出现此错误。
- 对于托盘图像，我在我的资产文件夹中添加了一个 webp 图标，并在托盘图像文件字段中提供了它的名称。
需要什么： - 我从 firebase 获取的自定义贴纸包应该添加到 WhatsApp 中，包括正常和动画。
这是从我的项目创建的 json 文件
