在Android Studio中增加Debug（logcat？）大小

Question

我有这个java.lang.IndexOutOfBoundsException问题，我想在我的代码中跟踪它，但Android Studio没有给我足够的Back Stack（Debug和Logcat选项卡）来查看问题的开始位置。我想增加显示的调试信息的大小，但我不知道该怎么做。

我已经尝试过这里显示的两种方法：Android Studio logcat history/buffer size但它们似乎不起作用，我总是得到相同的调试信息。

不是您要求的确切解决方案，而是获得异常跟踪的最佳方法之一。

您应该使用以下命令记录Crashlytics上的所有异常：

Crashlytics.logException(e);

所有记录的异常都将报告为非致命错误。
