Pixel Experience For Osborn（编译记录）

1、环境准备：

Install the platform-tools

If you haven’t previously installed adb and fastboot, you can download them from Google. Extract it running:

unzip platform-tools-latest-linux.zip -d ~

Tip: The file may not be named identically to what stands in this command, so adjust accordingly.

Now you have to add adb and fastboot to your PATH. Open ~/.profile and add the following:

# add Android SDK platform tools to path
if [ -d "$HOME/platform-tools" ] ; then
    PATH="$HOME/platform-tools:$PATH"
fi

Then, run source ~/.profile to update your environment.

Preparing your system to build

check

Tip: This guide assumes that you have Ubuntu 18 (or higher) installed.

Installing git:

sudo apt install git

Running configuration script:

cd ~/
git clone https://github.com/akhilnarang/scripts
cd scripts
./setup/android_build_env.sh

Create the directories

You’ll need to set up some directories in your build environment.

To create them:

mkdir -p ~/bin
mkdir -p ~/android/pe

The ~/bin directory will contain the git-repo tool (commonly named “repo”) and the ~/android/pe directory will contain the source code of PixelExperience.

Install the `repo` command

Enter the following to download the repo binary and make it executable (runnable):

curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo

Put the `~/bin` directory in your path of execution

In recent versions of Ubuntu, ~/bin should already be in your PATH. You can check this by opening ~/.profile with a text editor and verifying the following code exists (add it if it is missing):

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

Then, run source ~/.profile to update your environment.

Configure git

Given that repo requires you to identify yourself to sync Android, run the following commands to configure your git identity:

git config --global user.email "[email protected]"
git config --global user.name "Your Name"

Initialize the PixelExperience source repository

The following branches can be used to build for the OnePlus 5T:

twelve (discontinued)
twelve-plus (discontinued)
eleven (discontinued)
eleven-plus (discontinued)

Enter the following to initialize the repository:

info_outline

Note: Make sure the branch you enter here is the one you wish to build!

cd ~/android/pe
repo init -u https://github.com/PixelExperience/manifest -b branch_name

Download the source code

To start the download of the source code to your computer, type the following:

repo sync -c -j$(nproc --all) --force-sync --no-clone-bundle --no-tags

2、同步代码

（2）设备树代码同步：

1）Device：

git clone [email protected]:wxwxwz/android_device_smartisan_osborn.git -b lineage-17.1 device/smartisan/osborn

2) Kernel:

git clone https://github.com/wxwxwz/android_kernel_smartisan_sdm660.git -b lineage-17.1 kernel/smartisan/sdm660

3、Vendor

git clone [email protected]:wxwxwz/android_vendor_smartisan_osborn.git -b lineage-17.1 device/smartisan/osborn

自定义源码配置

1、修改NTP
目录：frameworks/base/core/res/res/values/config.xml
NTP服务器示例：time.apple.com（苹果）

2、修改captive portal
目录：packages/modules/NetworkStack/res/values/config.xml
Captive地址示例：https://connectivitycheck.platform.hicloud.com/generate_204（华为）

//如果修改了某些配置，只需要进行一下步骤便可只编译修改的部分

//如果遇到inja failed with: exit status 1,则有可能是交换内存关闭，启动即可（或直接重启系统）

Bug记录：

1、无法启动音频服务导致卡第二屏：
(1)替换frameworks/av/相关文件：使用patch文件（git am **.patch）
(2)替换hardware/interfaces相关文件，同上。
(3)重新编译
