使用 NativeModules 时，在 React Native 中“必须被捕获或声明为抛出”

Question

我想构建一个本机模块来对重启设备进行本机反应。我发现这个在java中以编程方式关闭设备。它在 android studio 中单独工作，但是当我尝试在本机模块中使用它时，出现以下错误https://pasteboard.co/IztJ6ll.jpgC:\Users\Ali\Desktop\Android\ReactNative\ReactNativeTest\android\app\src\main\java\com\reactnativetest\ToastModule.java:42: error: unreported exception IOException; must be caught or declared to be thrown    Process proc = Runtime.getRuntime().exec(new String[] { "su", "-c", "reboot" });                                            ^C:\Users\Ali\Desktop\Android\ReactNative\ReactNativeTest\android\app\src\main\java\com\reactnativetest\ToastModule.java:43: error: unreported exception InterruptedException; must be caught or declared to be thrown      proc.waitFor();                  ^2 errors> Task :app:compileDebugJavaWithJavac FAILEDFAILURE: Build failed with an exception.* What went wrong:Execution failed for task ':app:compileDebugJavaWithJavac'.> Compilation failed; see the compiler error output for details.* Try:Run with --stacktrace option to get the stack trace.

它就在日志中：

C:\Users\Ali\Desktop\Android\ReactNative\ReactNativeTest\android\app\src\main\java\com\reactnativetest\ToastModule.java:43: 错误：未报告异常 InterruptedException; 必须被捕获或声明抛出 proc.waitFor();

proc.waitFor()抛出异常。您应该用 try-catch 包围它，或者在方法签名中声明throws InterruptedException并在其他地方处理它
