Android Native crash tomestone trace批量轉換方法

      最近在跟進一個native crash的問題，偶然發現Android 5.0及其以上的版本源代碼下有批量轉換 Native trace 工具 development/scripts/stack，特此記錄一下.

      幫助資訊如下：

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檔案主要是當發生native crash 産生的tomestone墓碑檔案，下面就來示範一下具體的使用方法，其中會将所有的tomestone批量trace出來，友善開發者跟蹤錯誤的natve代碼，而不需要使用傳統的addrline2或者ndk-stack一個個的進行查找

     下面是截取轉換後的一段trace資料，可以非常清晰的看見調用流程，這樣遠比使用addrline2或者ndk-stack來得友善
