# LKD3568 Android11 系统架包使用步骤

## 1.编译生成系统架包
- 下载LKD3568源码并编译，参考[Android11系统编译](http://wiki.neardi.com/wiki/rk3568/zh_CN/docs/android/build.html)
- 生成的系统架包路径：`LKD3568-SDK-Android/out/soong/.intermediates/frameworks/base/framework-minus-apex/android_common/combined/framework-minus-apex.jar`

## 2.Android Studio如何使用系统架包

### 2.1.拷贝架包
`framework-minus-apex.jar`拷贝至`Project/app/libs`目录，重命名成`framework.jar`

### 2.2.添加依赖
`compileOnly`只参与编译，不会打包进应用，修改`Project/app/src/build.gradle`
``` shell
dependencies {
    compileOnly fileTree(dir: 'libs', include: ['*.jar'])
    compileOnly files('libs/framework.jar')
    ...
}    
``` 
### 2.3.配置IDE
优先使用`framework.jar`，修改`Project/app/src/build.gradle`
``` shell
android {
    ...
    gradle.projectsEvaluated {
        tasks.withType(JavaCompile) {
            Set<File> fileSet = options.bootstrapClasspath.getFiles()
            List<File> newFileList =  new ArrayList<>();
            newFileList.add(new File("libs/framework.jar"))
            newFileList.addAll(fileSet)
            options.bootstrapClasspath = files(newFileList.toArray())
        }
    }
}    
``` 
### 2.4.系统应用声明
修改`Project/app/src/main/AndroidManifest.xml`
``` shell
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    ...
    android:sharedUserId="android.uid.system"
>  
```
## 3.编译应用
- 执行`Make Project`或`F9`
- 生成的app路径：`Project/app/build/outputs/apk/debug/app-debug.apk`

## 4.系统签名
- 拷贝`app-debug.apk`至`Project/signtools`目录
- 执行签名命令
``` shell
java -jar signapk.jar platform.x509.pem platform.pk8 app-debug.apk FrameworkApiTest.apk
```
- `FrameworkApiTest.apk`即为签好名的系统应用

## 5.安装应用
调试阶段应用可以直接push至设备`/system/app`目录，后续需内置到ROM中
``` shell
adb root
adb remount
adb push FrameworkApiTest.apk /system/app/
adb reboot
```

## 6.系统API如何使用
以获取当前以太网名称为例
``` shell
EthernetManager mEthManager = (EthernetManager) getSystemService("ethernet");
//See LKD3568-SDK-Android/packages/apps/Settings/src/com/android/settings/ethernet/EthernetSettings.java
String[] ifaces = mEthManager.getAvailableInterfaces();
if (ifaces.length > 0) {
   mIfaceName = ifaces[0];//"eth0";
   String ifaceNameDebug = String.format("mIfaceName:%s ", mIfaceName);
   Log.d(TAG, ifaceNameDebug);
}
```
