一般在ndk崩溃的时候，完全看不懂崩溃日志，在网上了解以后，发现ndk有提供解析的工具，我使用的add2line，参考网上的python脚本的实例，最后借助Android Studio的External Tools，最后的效果如下：

只要在当前工程下随便创建一个文件，存储对应backtrace的log，右键运行External Tools，就可以解析出错的文件了

步骤

python脚本

#!/usr/bin/env python
# coding=utf-8
import argparse
import os
import re

import sys

NdkPath = "D:/Android/Sdk/ndk/22.1.7171670" #ndk路径
ProjectDir = "D:/WorkSpace/Android/xxx" #对应安卓工程路径


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("开始解析")

    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)

                # 解析调用栈
                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)

以上脚本解析的是arm64-v8a的包，自己可以根据情况改改，然后symbolDir可以得看看你的as版本了，生成的so是不是在这个路径下

AS External tools配置

AS菜单 File > Setting > Tools > External Tools

ndk位置我在python脚本里面写死了，上面就没加
