定制Android系统(编译Xposed和刷机)

编译完aosp源码，就开始编译xposed了

编译环境

安卓设备 sailfish 编译环境 MacOS（10.15绝对是坑）推荐kali（最终是在kali上搞定）

安装工具

• 更新&&配置
• 安装git

apt install git -y
git config --global user.email "your mail"
git config --global user.name "your name"
apt install -y gcc make libstdc++.i686 libstdc++-devel.i686 zlib-devel openssl-devel perl cpio expat-devel gettext-devel autoconf glibc.i686 glibc-devel.i686 zlib-devel.i686 libstdc++.i686 libX11-devel.i686 ncurses-devel.i686 ncurses-libs.i686 gperf flex gcc-c++ bison patch
apt install -y java-1.8.0-openjdk.x86_64 java-1.8.0-openjdk-devel.x86_64 java-1.8.0-openjdk-headless.x86_64
apt install perl -y
apt -q perl-CPAN

• 安装repo工具

mkdir ~/bin
PATH=~/bin:$PATH
curl -sSL  'https://gerrit-googlesource.proxy.ustclug.org/git-repo/+/master/repo?format=TEXT' |base64 -d > ~/bin/repo
chmod +x ~/bin/repo
export REPO_URL='https://mirrors.tuna.tsinghua.edu.cn/git/git-repo'

• 装个看CPU、内存、缓存的htop

yum install htop -y

同步源码

我们有两种方式同步源码，清华和谷歌，这次试用的是腾讯云，就用清华了。

• 创建存放源码的文件夹

mkdir n/
cd /root/n/

• 初始化仓库  从清华的服务器同步

repo init -u https://android.googlesource.com/platform/manifest

也可以指定特定的版本同步源码,记得输入y 选择源码版本 https://source.android.com/setup/start/build-numbers#source-code-tags-and-builds 以Pixel为例, 对应的Android 7源码tag是android-7.1.2_r33, build id是NZH54D. PS: 这里版本不要选错,不然后面没办法成功刷机.

repo init -u https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/platform/manifest -b android-7.1.2_r33 --depth=1

• 同步源码树 下面三行命令其中一行就行。

repo sync
repo sync -j8 #8个线程同步代码
nohup repo sync -j8 >>sync.log 2>&1 & #推荐：后台去同步，ssh断开也没事。

可以看到htop下，多个cpu已经跑起来了。

同步xposed源码

• XposedTools

cd ~
git clone https://github.com/rovo89/XposedTools.git

修改配置文件

cp build.conf.sample build.conf
vim build.conf

如下配置

   [General]
   outdir = /Users/zxc/Android/n/out #输出目录，out一定要存在
   javadir = /Users/zxc/Android/n/XposedBridge #XposedBridge的 位置

   [Build]
   # Please keep the base version number and add your custom suffix
   version = 89 (custom build by xyz / %s)#我们这里是89版本
   makeflags = -j8 #8个线程同步

  [GPG]
  sign = release
  user = 852109AA!

  # Root directories of the AOSP source tree per SDK version
 [AospDir]
  #19 = /android/aosp/440
  #21 = /android/aosp/500
  25 = /Users/zxc/Android/n #安卓7.1源码位置，上边两个注释
  # SDKs to be used for compiling BusyBox
  # Needs https://github.com/rovo89/android_external_busybox
  [BusyBox]#下面的都改成25，看资料说不改也行
  arm = 25
  x86 = 25
  armv5 = 25

• xposed xposed为整个Xposed框架的native部分,主要内容为xposed修改的app_process源码和相关库文件.这里需要提一下,这部分源码有两种同步方式.第一采用修改local_manifests,然后repo sync的方式.第二种则为手动下载合并.本文采用第二种方式.

cd /Users/zxc/Android/n
cd frameworks/base/cmds/
git clone https://github.com/rovo89/Xposed.git xposed

• android_art Xposed为了支持新的runtime,修改了art的源码.我们需要把原来的art源码替换成Xposed提供的代码.

cd /root/n
rm -rf art
git clone https://github.com/rovo89/android_art.git -b xposed-nougat-mr2  art

• XposedBridge XposedBridge的代码直接clone即可,没有版本的限制.需要注意与javadir对应.

cd /root/n
git clone https://github.com/rovo89/XposedBridge.git

安装

• 下载地址 (自己提取的，没测试) https://dl.google.com/android/repository/platform-25_r03.zip https://dl.google.com/android/repository/sources-25_r01.zip 之前在as里面已经装了，就不在装了。我们需要改XposedBridge/app/build.gradle为下面的（这里是安卓7.1就是sdk25）。在XposedBridge/local.properties添加

 sdk.dir=/Users/zxc/Android/sdk#自己的sdk目录

编译

• 初始化编译环境

source build/envsetup.sh
lunch 18

• 编译XposedBridge

cd /root/XposedTools
 ./build.pl -a java

编译完成

BUILD SUCCESSFUL

Done!

• 编译native层代码

 ./build.pl -t arm64:25 #25是sdk版本 对应安卓7.1

file

错误

kali

• flex-2.5.39: fatal internal error, exec of /usr/bin/m4 failed

sudo apt-get  install libxml2-utils

刷机

这里不能直接刷进去 感谢肉丝大佬的指点 修改XposedInstaller的源码 这里的url都换成你自己的

    public Builder setUrl(String url) {
            mUrl = url;
            System.out.println("xposed=" + url);
            if (url.contains("uninstaller")) {
                mUrl = "http://192.168.2.185:8000/xposed-uninstaller-20180117-arm64.zip";
            } else {
                mUrl = "http://192.168.2.185:8000/xposed-v89-sdk25-arm64-custom-build-by-xyz-20200726.zip";
            }
            return this;
        }

file

• 刷入错误
  
• 这里下载一下官方的卸载zip，替换下 先刷入卸载包，再刷入安装包即可

mac

mac10.15 劝退

• python3会出现 print错误 修改build/tools/findleaves.py里面的print r为print(r) 即可

• 大小写敏感问题 mac 分区是默认不是大小敏感，所以需要重新分区。参考这里 https://blog.bihe0832.com/mac-disk-utility.html

• Can not find SDK 10.8 at /Developer/SDKs/MacOSX10.8.sdk 解决办法就是将mac_sdk_versions_supported改为系统中所装版本或者自己下载一个放在sdk目录

export MAC_SDK_VERSION="10.11"

https://github.com/phracker/MacOSX-SDKs/releases/download/10.11/MacOSX10.8.sdk.tar.xz

#mac_sdk_versions_supported := 10.6 10.7 10.8 10.9
mac_sdk_versions_supported := 10.11

• Bad CPU type in executable

brew install wsk

external/libcxx/include/cstdlib:167:44: error: declaration conflicts with target of using declaration already in scope

 解决办法：见stackoverflow，Xcode降级到8.3.3
