准备工作

• android ndk（里面包含64位的addr2line执行文件） developer.android.google.cn/ndk/downloa…
• not stripped的so文件（带symbols信息） 路径：out/target/product/qssi_64/symbols/system/lib64/*.so

查看bin文件的tripped状态

我们可以使用 file <file path> 来查看 可以看到symbols路径下的bin文件为not stripped状态，不带symbols的路径下的bin文件为stripped状态。 注意：symbols lib库必须是与用来复现问题的bin在同一次build出来的才可以

在执行文件中添加调用堆栈打印进行验证

1. 导入CallStack头文件
2. 调用CallStack::logStack方法打印堆栈

#include <utils/CallStack.h>
CallStack::logStack("qinbin");

使用方法

./android-ndk-r26c/toolchains/llvm/prebuilt/linux-x86_64/bin/llvm-addr2line -C -f -e <file path> <address>

llvm-addr2line -h
