步骤

注意：这个过程需要在Android源码环境中运行，可以使用adb端口转发工具，来连接服务器端的源码进行运行

关于adb端口转发：请看https://www.cnblogs.com/pyjetson/p/14828485.html

1. 运行gdbclient.py脚本

首先是使用vscode remote ssh终端连接服务器
1. 找到进程的pid号
adb shell "ps -A | grep vold"

2. 运行gdbclient.py脚本
gdbclient.py -p 20750 --setup-forwarding vscode

2. 复制生成的launch.json并新建/home/jetson/android_aosp/aosp/.vscode/launch.json

    "configurations": [

        {

                    "description": "gdb command: set solib-search-path", 
                    "ignoreFailures": false
                },
                {
                    "text": "-gdb-set solib-absolute-prefix /home/jetson/android_aosp/aosp/out/target/product/generic_x86/symbols", 
                    "description": "gdb command: set solib-absolute-prefix", 
                    "ignoreFailures": false
                }, 
                {
                    "text": "-interpreter-exec console \"source /home/jetson/android_aosp/aosp/development/scripts/gdb/dalvik.gdb\"", 
                    "description": "gdb command: source art commands", 
                    "ignoreFailures": false
                }
            ], 
            "name": "(gdbclient.py) Attach vold (port: 5039)", 
            "miDebuggerServerAddress": "localhost:5039", 
            "request": "launch", 
            "type": "cppdbg", 
            "cwd": "/home/jetson/android_aosp/aosp", 
            "MIMode": "gdb"
        }
    ]
}

3. 运行gdb即可，打断点

参考

1. 使用调试程序
