java - 如何查找并调试实际代码行 Java 错误 : Fatal Exception: java. lang.IndexOutOfBoundsException:

Question

我的 crashletics 日志中出现以下错误，我知道此错误与数组索引超出范围有关，并且我知道如何修复它，

但是，我的问题是我到底如何从下面的日志中找到发生这种情况的位置，因为日志中的所有提示都是通用的并且代码库非常大，因此很难用断点检查所有地方，并且由于在某些竞争条件下很少发生，任何人都可以给我关于如何找到答案的正确方向的线索吗？

我会看看这一行

android.widget.ArrayAdapter.getItem + 385 (ArrayAdapter.java:385)

这表明您的 ArrayAdapter 中发生了错误。

因为项目中没有很多适配器，所以我认为这是跟踪错误的合理起点
