本文实例讲述了Android调用堆栈跟踪的方法。分享给大家供大家参考。具体如下：
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：

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。
希望本文所述对大家的Android程序设计有所帮助。
