Andoid 利用ndk-stack定位崩溃代码

标签：

Android NDK自从版本R6开始, 提供了一个工具ndk-stack( 在目录{ndk_root}/中 ). 这个工具能自动分析dump下来的crash log, 将崩溃时的调用内存地址和c++代码一行一行对应起来.

执行命令ndk-stack --help

Usage:
   ndk-stack -sym <path> [-dump <path>]

      -sym  Contains full path to the root directory for symbols.
      -dump Contains full path to the file containing the crash dump.
            This is an optional parameter. If ommited, ndk-stack will
            read input data from stdin

• -dump参数很容易理解, 即dump下来的log文本文件. ndk-stack会分析此文件.
• -sym参数就是你android项目下,编译成功之后,obj目录下的文件.

示范一下:

$ adb logcat | ndk-stack -sym ./obj/local/armeabi
