Question

我正在编辑anandroid应用程序，该应用程序基于我之前曾做过的类似工具。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.

我的日志显示了这个：

我不知道这些位置在哪里，所以也许我只是错过它。

Full Logcat，但有例外：

我的控制台显示一切正常运行，直到：

  [2012-04-28 01:48:17 - Emulator] emulator: WARNING: Unable to create sensors port: Unknown error
[2012-04-28 01:48:17 - Buchanan_JavaQuizGame] New emulator found: emulator-5554

Answer 1

可能是因为有两个仿真器同时打开。

Answer 2

在您的代码中的某个位置，您使用nextInt类的Random方法，我认为您将其传递为负integer，这将抛出IllegalArgumentException（它需要方法参数为正）。

在您的resetQuiz方法中会发生这种情况，因此请检查您在代码中执行的操作。
