Android Native crash tomestone trace批量转换方法

      最近在跟进一个native crash的问题，偶然发现Android 5.0及其以上的版本源代码下有批量转换 Native trace 工具 development/scripts/stack，特此记录一下.

      帮助信息如下：

usage: ./development/scripts/stack [options] [FILE]

  --arch=arm|arm64|mips|mips64|x86|x86_64
       the target architecture

  FILE should contain a stack trace in it somewhere
       the tool will find that and re-print it with
       source files and line numbers.  If you don't
       pass FILE, or if file is -, it reads from
       stdin.

           

     其中的FILE文件主要是当发生native crash 产生的tomestone墓碑文件，下面就来演示一下具体的使用方法，其中会将所有的tomestone批量trace出来，方便开发者跟踪错误的natve代码，而不需要使用传统的addrline2或者ndk-stack一个个的进行查找

     下面是截取转换后的一段trace数据，可以非常清晰的看见调用流程，这样远比使用addrline2或者ndk-stack来得方便
