Android 调用堆栈跟踪

时间：2014-05-16 09:14:49 收藏：0 阅读：551

Android开发中，我们也会经常遇到段错误，也就是SIGSEGV（11），这个时候libc的backtrace会打印出对应的堆栈信息，而你看到的仅仅是一对数字，好像无从查起。

如下面这一从串断错误：

I/DEBUG (13002): 4ebe0a94 a86167b7 /system/lib/libwebcore.so

我们的板子上的lib 经常被strip过了，没有了符号信息。不过我们可以通过编译时候生成的库来获取对应的符号信息。编译器也为我们提供了相应的工具:addr2line 全名为：arm-eabi-addr2line ，可在对应板子源码目录找到。

通过上面的断错误分析，位于system/lib/libwebcore.so 这个库出现了断错误，可以将其pull下来正逐行分析。命令为：arm-eabi-addr2line -f -e ~/桌面/libwebcore.so 0038f2de

这种分析法同样适用于使用jni开发的库。
