## Build AOSP
### Build compile environment
1. Install Ubuntu 18.04
2. Install packages: `sudo apt-get install git-core gnupg flex bison build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z1-dev libgl1-mesa-dev libxml2-utils xsltproc unzip fontconfig`
- https://source.android.com/setup/build/initializing
3. Install Repo
```
mkdir ~/bin
PATH=~/bin:$PATH
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo ;\
chmod a+x ~/bin/repo ;\
gpg --recv-key 8BB9AD793E8E6153AF0F9A4416530D5E920F5C65 ;\
curl https://storage.googleapis.com/git-repo-downloads/repo.asc | gpg --verify - ~/bin/repo
```
- https://source.android.com/setup/develop#installing-repo
4. Download AOSP source
1. Create folder for AOSP
```
mkdir -p ~/codes/aosp ; cd ~/codes/aosp
```
2. Setup git
```
git config --global user.name AwinHuang ;\
git config --global user.email awinhuang@gmail.com
```
3. Download source code
```
repo init -u https://android.googlesource.com/platform/manifest ;\
repo sync -j8
```
- 如果要切換某一個特定版本可以使用`-b`，例如：`repo init -u https://android.googlesource.com/platform/manifest -b android-10.0.0_r47`。
- 要知道版本tag可以查看：https://source.android.com/setup/start/build-numbers#source-code-tags-and-builds
5. Build code
```
source build/envsetup.sh ;\
lunch aosp_arm-eng ;\
make clobber ;\
make -j16
```
- `make clobber`用來刪除build資料夾

- [Android AOSP基础（三）Android系统源码的整编和单编 | BATcoder - 刘望舒](http://liuwangshu.cn/framework/aosp/3-compiling-aosp.html)
## Build kernel
1. Download the code
```
mkdir -p ~/codes/kernel ;\
cd ~/codes/kernel ;\
repo init -u https://android.googlesource.com/kernel/manifest ;\
repo sync -j16
```
2. Compile
```
build/build.sh
```
- 如果遇到`Command 'java' not found, but can be installed with:`
- 依序安裝
- `sudo apt install default-jre`
- `sudo apt install openjdk-11-jre-headless`
- `sudo apt install openjdk-8-jre-headless`
- 執行 `sudo update-alternatives --config java`
- 選擇 `/usr/lib/jvm/java-11-openjdk-amd64/bin/java`
- 再次compile
- `source build/envsetup.sh`
- `mm idegen`
3. 產生android.iml和android.ipr
在source code跟目錄下執行：`development/tools/idegen/idegen.sh`

## Android App programming
- R的全名：`<PACKAGE_NAME> + .R`，例如package name是`com.awin.testapp`，那全名是`com.awin.testapp.R`。
- AndroidX = Android eXtension
- Layout
- layout_margin: 物件與其他物件的距離
- layout_gravity: 物件在容器內的位置（靠左、靠右、置中...）
- textApperance: 字型大小
- Extensions
- Android 4.1 沒有自動加入的extension
- 打開build.gradle，在`plugins`區塊中加入：
```
id 'kotlin-kapt'
id 'kotlin-android-extensions'
```
- 使用ViewModel & LiveData
- 確認有 `kotlin-kapt` 這個plugin。
![[Pasted image 20210330102148.png]]
- [Android jetpack所有library](https://developer.android.com/jetpack/androidx/explorer)
- [Android jetpack - Lifecycle](https://developer.android.com/jetpack/androidx/releases/lifecycle)
- 從`Declaring dependencies`這區塊複製必要的module
![[Pasted image 20210330110411.png]]
```
def lifecycle_version = "2.3.1"
// ViewModel
implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:$lifecycle_version"
// LiveData
implementation "androidx.lifecycle:lifecycle-livedata-ktx:$lifecycle_version"
// Annotation processor
kapt "androidx.lifecycle:lifecycle-compiler:$lifecycle_version"
```
- Create a ViewModel
```kotlin
viewModel = ViewModelProvider(this).get(GuessViewModel::class.java)
```
- Observe a live data in ViewModel
```kotlin
viewModel.counter.observe(this, Observer {
counter.setText(it.toString())
})
```
counter這個變數是包含在ViewModel裡面的live data，我們的資料則是放在counter裡面的「value」。
所以如果要取用我們的data，則是：`viewModel.counter.value`。
- 使用LiveData
- `val counter = MutableLiveData<Int>()`
### Use ViewBinding
ViewBinding is used to replace Kotlin Synthetics.
1. 在`app/build.gradle`中加入：
```
plugins {
...
id 'kotlin-parcelize' <-- Add this
}
android {
...
buildFeatures { <-- Add this
viewBinding true
}
...
}
```
2. 在你的activity裡面
1. `import <APP_DOMAIN_NAME>.databinding.<ACTIVITY_NAME>Binding`
假如：APP_DOMAIN_NAME是`com.example.testmultisectioncyclerview`，ACTIVITY_NAME是`ActivityMain`，那就是：
`import com.example.testmultisectioncyclerview.databinding.ActivityMainBinding`
2. 用`lateinit`宣告一個變數，變數名稱是activity的名字加上binding，例如`ActivityMain`就是：
`private lateinit var activityBinding: ActivityMainBinding`
3. 在`onCreate()`中，就可以用`activityBinding`來取得view與其他元件了：
```
activityBinding = ActivityMainBinding.inflate(layoutInflater)
setContentView(activityBinding.root) <-- root就是view
```
