我正在编辑一个基于我之前做过的类似应用的安卓应用。这次它不起作用，但我不知道为什么。

应用程序错误：

The Application Buchanan Java Quiz Game (process hu.csc395.javaquizgame) has stopped unexpectedly Please Try again.

我的日志显示：

我不知道这些在哪里，所以也许我只是想念它。

完整的 Logcat 除外：

可能是因为同时打开了两个模拟器。

在您的代码中的某处，您使用了类的nextInt方法，Random我认为您将其传递给负数integer，这将抛出IllegalArgumentException（它要求方法参数为正数）。

这发生在您的resetQuiz方法中，因此请检查您在代码中所做的事情。
