-Xstacktracefile选项之后,就可以将线程的调用堆栈输出指定的文件中去。可以通过"dalvik.vm.stack-trace-file"系统属性来调用堆栈输出文件。 第5部分:添加一些常用配置,注释已经很清楚了,这里就不说了 第6部分:添加虚拟机的堆大小,这里看见大的heapsize,给16M。虚拟机用"-Xmx"来制定Java堆的最大值。我们...

在我们这个技术驱动的社会中,小工具和硬件只是硬币更明显的一面。在这一章中,我们将讨论编程的基础知识。我们还将看看数字系统的可见部分:硬件。 到底什么是编程? 基本上,编程是告诉数字设备,比如你的个人电脑,做什么的行为。我们键入由编程语言定义的命令列表,以便发生有用或有趣的事件。正确编程的计算机运行着世界...

throw;preserves the original stack trace of the exception, which is stored in theException.StackTraceproperty. Opposite to that,throw e;updates theStackTraceproperty ofe. When an exception is thrown, the common language runtime (CLR) looks for thecatchblockthat can handle this exception. If the...
In #203 and #623 we discussed printing the Java stacktrace by default, in order to assist developers with problems happenning within Java. This PR does this by overridding __str__(), without trying...
