Android中使用addr2line来分析native信息
系统：Ubuntu12.04
手机系统：Android5.0
在Android的开发过程中有会有很多的native bug必须要用addr2line来分析，并且这个工具也非常的好用。下面我们来看看具体的使用。
烧录到手机上的版本和你电脑上的编译出的版本要一致，这个数据才是准确的，才好定位到那一行。
首先找到自己电脑可用的addr2line，用命令find . -name *addr2line。我的如下
@njws19:~/qcom8974_l_row/LINUX/android$ find . -name *addr2line
./external/chromium_org/build/android/pylib/symbols/mock_addr2line

你自己随便找一个可用的addr2line使用，我这里选用的是./prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.11-4.6/bin/x86_64-linux-addr2line
首先是在电脑上编译出一个eng版本，烧录到手机，在测试或调试的过程中出错了，查看出错信息如下：

出错代码信息可以在电脑上（在你编译系统的android目录）查找：libskia.so
查找结果如下
@njws19:~/qcom8974_l_row/LINUX/android/out/target$ find -name libskia.so
./product/kingdom_row/obj/lib/libskia.so
./product/kingdom_row/obj/SHARED_LIBRARIES/libskia_intermediates/LINKED/libskia.so
./product/kingdom_row/obj/PACKAGING/target_files_intermediates/kingdom_row-target_files-K920_S204_150127_ROW/SYSTEM/lib/libskia.so

./product/kingdom_row/symbols/system/lib/libskia.so
./product/kingdom_row/system/lib/libskia.so
有用的信息是这行，带有symbols字样的 ./product/kingdom_row/symbols/system/lib/libskia.so
这样就可以使用addr2line来查找出错的文件行数，
