1 Quick Start
1.1 Step 1 Include libfriendlyarm-things.so in APP
Clone the following library locally:
git clone https://github.com/friendlyarm/friendlythings-sdk
Copy all the files under the libs directory to your working directory and create a "com/friendlyarm" directory in your Android project's src directory, copy the whole "java/FriendlyThings" to your newly created "com/friendlyarm" directory. The whole project directory will look like this(Note:AndroidStudio's project may be a little bit different):
YourProject/
├── AndroidManifest.xml
├── libs
│ ├── arm64-v8a
│ │ └── libfriendlyarm-things.so
│ └── armeabi
│ └── libfriendlyarm-things.so

│ │ ├── GPIOEnum.java
│ │ ├── HardwareControler.java

│ │ ├── SPI.java
│ │ └── WatchDogEnum.javaImport the following components and the major APIs are included in the HardwareControler.java file:
import com.friendlyarm.FriendlyThings.HardwareControler; import com.friendlyarm.FriendlyThings.SPIEnum; import com.friendlyarm.FriendlyThings.GPIOEnum; import com.friendlyarm.FriendlyThings.FileCtlEnum; import com.friendlyarm.FriendlyThings.BoardType;
1.2 (第2步) 让你的app拥有system权限
你的app需要拥有system权限，才能访问硬件资源;
请参考下面的方法修改你 app 的 AndroidManifest.xml 和 Android.mk这两个文件;
并且最好将你的app放到Android源码中去编译，这一步不是必需的，但是建议这么做，如果你的app在外部编译，你需要对apk进行签名才能让你的app拥有system权限（新手不太建议，过程比较繁琐）。
1.2.1 修改AndroidManifest.xml
在应用程序的AndroidManifest.xml中的manifest节点中加入以下属性：
android:sharedUserId="android.uid.system"
1.2.2 修改Android.mk
编写一个Android.mk文件(最简单的方法就是拷贝示例中的Android.mk文件)，修改Android.mk文件，加入LOCAL_CERTIFICATE := platform这一行:
LOCAL_PATH:= $(call my-dir) include $(CLEAR_VARS) LOCAL_SRC_FILES := $(call all-subdir-java-files) LOCAL_PACKAGE_NAME := 你的项目名 LOCAL_CERTIFICATE := platform LOCAL_MODULE_TAGS := optional LOCAL_CFLAGS := -lfriendlyarm-hardware include $(BUILD_PACKAGE)
1.3 (最后1步) 在 Android源代码中编译你的app
先在 Android源代码根目录调用 setenv.sh 导出环境变量，然后进入你的 app 目录，使用mm命令编译;
例子：编译 GPIO_LED_Demo，以RK3399平台为例:
cd rk3399-android-8.1 . setenv.sh cd vendor/friendlyelec/apps/GPIO_LED_Demo mm
