android - 特有的android RuntimeException

Question

我刚刚在我的开发者控制台上收到了看起来最奇怪的堆栈跟踪。令我困惑的是“MArcos”从何而来？这是应用程序:https://play.google.com/store/apps/details?id=genius.mohammad.accelerometer.mouse

如果需要，请尝试重新创建异常，如果可以，请向我解释它是什么。谢谢!

Answer 1

Caused by: java.lang.NumberFormatException: unable to parse 'MArcos' as integer

在您的代码(MainActivity.java:第 85 行)中，您似乎正在尝试将 String 解析为 Integer。
