1、系统环境
操作系统：Windows11
虚拟机VirtualBox6.1：Downloads – Oracle VM VirtualBox
Ubuntu18.04.6:?https://releases.ubuntu.com/18.04/ubuntu-18.04.6-desktop-amd64.iso
VirtualBox主机与虚拟机不能复制粘贴的解决办法，要开启两项：
第1项：安装增强功能
第2项：选中使用主机输（I/O）缓存
2、GDB8.2 带python功能
a@sys:~$ gdb
GNU gdb (Ubuntu 8.1.1-0ubuntu1) 8.1.1
Copyright (C) 2018 Free Software Foundation, Inc.

This GDB was configured as "x86_64-linux-gnu".
Type "show configuration" for configuration details.

Find the GDB manual and other documentation resources online at:

Type "apropos word" to search for commands related to "word".
(gdb) python
>import os
>import sys
>print(sys.version_info)
>end
sys.version_info(major=3, minor=6, micro=9, releaselevel='final', serial=0)
(gdb)
如果gdb本身没有带python，需要自己安装，过程中注意事项如下：
安装Python2.7出现如下错误：
The following packages have unmet dependencies:
?python2.7 : Depends: python2.7-minimal (= 2.7.15~rc1-1) but it is not going to be installed
? ? ? ? ? ? ?Depends: libpython2.7-stdlib (= 2.7.15~rc1-1) but 2.7.17-1~18.04ubuntu1.6 is to be installed
E: Unable to correct problems, you have held broken packages.
则执行下面的安装命令：
sudo apt-get install aptitude
sudo aptitude install python2.7
其他辅助命令：查看进程的绝对路径
ll /proc/pid
sudo aptitude install gcc? ? 输入 n y y?
sudo apt-get install g++
sudo apt-get install?python2.7-dev
sudo apt-get install texinfo
wget http://ftp.gnu.org/gnu/gdb/gdb-8.2.tar.gz
tar zxf gdb-8.2.tar.gz
sudo aptitude install make
gdb-8.2$ ./configure?--with-python='/usr/bin/python2.7'
3、安装Android Studio
安装sdk ndk avd
设置$PATH
a@sys:~$ cat ~/.bashrc
export PATH=~/Android/Sdk/platform-tools:~/Android/Sdk/emulator:$PATH
开启虚拟机CPU VT虚拟化，并赋予kvm权限:
sudo chown a -R /dev/kvm
4、下载安卓内核源代码
repo init --depth=1 -u https://android.googlesource.com/kernel/manifest -b q-goldfish-android-goldfish-4.14-dev
