android - 尝试实现 ar core 时无法加载 Renderable

Question

为什么我在尝试创建 ar 应用程序时收到此错误？

Unable to load Renderable registryId='android.resource://com.nevco.ar/raw/cat'
    java.util.concurrent.CompletionException: java.lang.AssertionError: No RCB file at uri: android.resource://com.nevco.ar/raw/cat

我正在按照本教程创建一个简单的 ar 应用程序，但每次我启动我的应用程序时，我都会收到此错误。我不知道该怎么做才能解决这个问题。一些帮助将不胜感激。我附上了教程的链接。 https://www.androidauthority.com/google-arcore-972579/

检查你的模型是.sfb文件还是.obj文件。

.sfb 正在为我工​​作，但我在 .obj 中遇到同样的错误。
