一般在ndk崩潰的時(shí)候高蜂，完全看不懂崩潰日志聪黎，在網(wǎng)上了解以后，發(fā)現(xiàn)ndk有提供解析的工具备恤，我使用的add2line稿饰，參考網(wǎng)上的python腳本的實(shí)例，最后借助Android Studio的External Tools露泊，最后的效果如下：

只要在當(dāng)前工程下隨便創(chuàng)建一個(gè)文件喉镰，存儲(chǔ)對(duì)應(yīng)backtrace的log，右鍵運(yùn)行External Tools惭笑，就可以解析出錯(cuò)的文件了
步驟
python腳本
#!/usr/bin/env python
# coding=utf-8
import argparse
import os
import re
import sys
NdkPath = "D:/Android/Sdk/ndk/22.1.7171670" #ndk路徑
ProjectDir = "D:/WorkSpace/Android/xxx" #對(duì)應(yīng)安卓工程路徑
def getOptions(args=sys.argv[1:]):
parser = argparse.ArgumentParser(description="Parses command.")
parser.add_argument("-n", "--ndk", help="Your ndk path.")
parser.add_argument("-p", "--project", help="Your project path.")
parser.add_argument("-f", "--file", help="crash log file.")
options = parser.parse_args(args)
return options
def parser(projectDir, ndkPath, crashFilePath):
print("開始解析")
symbolDir = f"{projectDir}/app/build/intermediates/ndkBuild/debug/obj/local/arm64-v8a"
addr2lineFilePath = f"{ndkPath}/toolchains/aarch64-linux-android-4.9/prebuilt/windows-x86_64/bin" \
"/aarch64-linux-android-addr2line.exe "
p = re.compile(r"(.*#\d* pc) ([\da-zA-Z]*) /data/app/.*==/lib/arm64/([\w.]*).*", re.MULTILINE)
with open(crashFilePath, "r") as file:
for line in file:
if line.find("\n") < 0:
line += "\n"
matched = p.search(line)
if matched is not None:
head = matched.group(1)
pc = matched.group(2)
soName = matched.group(3)
# 解析調(diào)用棧
command = f"{addr2lineFilePath} -f -e {symbolDir}/{soName} {pc}"
f = os.popen(command)
read = f.read()
f.close()
print(line, end="")
print(f"{head} \u001b[31m{read}\u001b[0m", end="")
if __name__ == '__main__':
option = getOptions()
print(option)
if option.project is None:
option.project = ProjectDir
if option.ndk is None:
option.ndk = NdkPath
if option.file is None:
option.file = os.path.dirname(os.path.realpath(__file__)) + "/NdkCrash.txt"
parser(option.project, option.ndk, option.file)
以上腳本解析的是arm64-v8a的包侣姆，自己可以根據(jù)情況改改，然后symbolDir可以得看看你的as版本了沉噩，生成的so是不是在這個(gè)路徑下

ndk位置我在python腳本里面寫死了捺宗，上面就沒加
