我正在使用 Nativescript+Typescrit，我在原生插件中有一个 java 类和接口，我想直接在 typescript 中使用它们，为了清楚地描述问题，我做了一个简单的代码如下：
Java 接口是这样的：
package com.test;
public interface Animal {
public void eat();
}
Java 类使用此接口，如下所示：
package com.test;
public class Box {
private Animal animal;
public void setAnimal(Animal a){
this.animal = a;
}
public void startEat(){
this.animal.eat();
}
}
在打字稿中，我定义了一个类实现 Animal，如下所示：
@Interfaces(com.test.Animal)
export class Cat extends java.lang.Object {
constructor() {
super();
return global.__native(this);
}
public eat():void {
console.log("cat is eating");
}
}
现在我想像这样使用它：
import { Cat } from "./cat"
let box = new com.test.Box();
box.setAnimal(new Cat());
box.startEat();
在安卓模拟器中运行后，我收到此错误：

我花了很多时间检查这个问题，但没有想法，最有可能的是我错误地扩展了 Animal 接口，我是根据这个扩展类接口做的。
如果我在打字稿中使用接口，它可以工作：
import { Cat } from "./cat"
let box = new com.test.Box();
box.setAnimal(new com.test.Animal({
eat() {
console.log("I am eatting");
}
}));
box.startEat();
所以我徘徊为什么我不能在打字稿中扩展 java 接口，感谢任何有用的答案。
似乎重新启动模拟器并重新运行"tns 运行 android"无需任何更改即可解决此问题。
