未知：ReactNative：CatalystInstanceImpl 捕获本机异常 java.lang.RuntimeException：无法调用

Question

当我尝试从 React Native 模块调用函数时，它给我返回未知的错误：ReactNative：CatalystInstanceImpl 捕获本机异常 java.lang.RuntimeException：无法调用

\n

当我使用 Handler(Looper) 方法添加实际函数时，如果我只是打印或控制台模块方法的某些内容，它就会工作，它会抛出错误

\n

我下面的代码有什么问题？或者我错过了什么？

\n

这是我的本机模块类
