Android应用因错误关闭

Question

我的手机上安装了android应用。 每当我尝试打开该应用程序时，它将关闭并显示一条消息“该应用程序已意外停止”。 我试图从错误日志中找到原因，但是我无法理解出了什么问题。 这是日志中的错误部分：

E/Web Console(13393): Uncaught TypeError: Object [object Object] has no method 'scroller' at https://xxxx.xxxx.com/assets/js/m/common.js:2

E/Web Console(13393): Uncaught ReferenceError: module is not defined at https://xxxx.xxxx.com/assets/js/m/common.js:4

E/AndroidRuntime(13393): at com.myapp.MainActivity$WebFragment$1.onPageFinished(MainActivity.java:470)

谁能帮助我了解可能出了什么问题？ 这是我的MainActivity代码：

有没有一种方法可以避免上述错误，使应用程序可以正常运行？

Answer 1

您的commons.js中的javascript代码在commons.js文件的第2行和第4行中包含错误。 这就是日志输出所显示的内容。 修复它们后，该应用程序将不再崩溃。
