无法捕获且不会停止程序的错误
我正在运行一段代码,该代码在 Eclipse 中抛出错误。奇怪的是,logcat 显示抛出错误后程序继续运行,而且代码块正在正确执行其任务,但我无法捕获错误。这有可能是 eclipse 的 bug 吗?我在下面包含了我的 logcat。

I am running a piece of code that is throwing an error in eclipse. The strange thing is that the logcat shows that after the error is thrown the program keeps running, furthermore the block of code is performing it's task correctly, and I am unable to catch the error. Is it possible that this is an eclipse bug? I have included my logcat below.

尝试修复导致此行出现 NullPointerException 的代码(或将其作为问题的一部分发布):
您运行多个线程吗?恕我直言,这不太可能是 Eclipse 中的错误。
Try to fix the code which causes the NullPointerException at this line (or post it as part of your question):
Do you run several threads? IMHO It's highly unlikely that it is an bug in Eclipse.
