Android Native Crash捕获和处理

测试异常

测试异常代码如下：

extern "C" JNIEXPORT void JNICALL
Java_io_github_kongpf8848_ndk_demo_MainActivity_testCrash(
        JNIEnv *env,
        jobject clazz) {
    LOGD("testCrash");
    int *a = NULL;
    *a = 1;
}

在Logcat里看到的崩溃日志如下：

使用addr2line获取具体的崩溃信息

addr2line的本地地址如下：
/Users/kongpengfei/Desktop/jack/software/android-sdk-macos/ndk/21.4.7075529/toolchains/aarch64-linux-android-4.9/prebuilt/darwin-x86_64/bin/aarch64-linux-android-addr2line
执行如下命令：

aarch64-linux-android-addr2line -f -C -e libnative-lib.so 00000000000007b0

输出如下：

Java_io_github_kongpf8848_ndk_demo_MainActivity_testCrash
/Users/kongpengfei/Desktop/jack/workspace/Github/ndk-demo/Demo9/src/main/cpp/native-lib.cpp:19

可以看到具体出错代码的行数为第19行

Breakpad简介

‌Breakpad‌ 是一个开源的崩溃报告工具，主要用于捕获和分析应用程序中的崩溃信息。在Android平台上，Breakpad 可以帮助开发者捕获和分析Native层(C++)的崩溃信息。

Breakpad is a set of client and server components which implement a crash-reporting system.

构建

环境搭建

为了方便编译，我选择的是购买腾讯云轻量应用服务器，价格35元/月，配置如下：

系统镜像	地域	配置
Ubuntu 20.04.6 LTS	美国硅谷	CPU - 2核内存 - 2GB 系统盘 - SSD 云硬盘 60GB

安装depot_tools

下载depot_tools

git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git

配置环境变量

vim ~/.bashrc

export depot_tools=/root/depot_tools
export PATH=$depot_tools:$PATH

source ~/.bashrc

升级gcc到11版本以支持C++20

添加 PPA 仓库

sudo apt update
sudo apt install software-properties-common
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt update

安装gcc 11

sudo apt install gcc-11 g++-11

切换默认gcc版本

sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-11 110
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-11 110
# 选择默认版本
sudo update-alternatives --config gcc
sudo update-alternatives --config g++

获取源码

mkdir breakpad && cd breakpad
fetch breakpad

编译源码

cd src
./configure && make

编译成功后，输出的主要产物为：

src/libbreakpad.a //用来集成到客户端app中，收集崩溃信息
src/tools/linux/dump_syms/dump_syms //用来提取so文件的符号表信息
src/processor/minidump_stackwalk //用来从.sym符号文件和dump文件中提取崩溃时的堆栈信息
