mijiaSDK文档


目的

本文档为接入mijiaSDK的第三方开发者提供开发独立App的指导。

前提条件

在进行独立App开发前,您需要

基础准备

在您正式进行产品接入前,需要首先完成一下准备工作

1. 帐号接入

mijiaSDK目前支持小米帐号登陆,开发者需要到小米帐号开放平台注册自己的App信息,并在小米帐号系统Oauth权限管理中,申请并审核通过“智能家庭服务”权限,请确保申请通过此权限,否则不能正常使用。如果在接入过程中遇到问题,可加QQ群385428920咨询。然后下载小米帐号最新版SDK,并集成到自己应用中。

2. 消息推送

mijiaSDK中集成有Mipush,目前主要是用于订阅设备事件。App使用前,开发者需要到小米消息推送服务注册自己的App信息。

3. 注册AppId,AppKey以及设备信息

将应用注册到小米帐号时,会生成相关的AppId和Appkey,需要将这部分信息注册到智能家居后台。

产品接入

1. 云端配置产品信息

将应用需要支持的设备信息注册到智能家居后台。

2. 撰写设备功能描述文档

首先,这里简述一下MiotDevice的模型,一个Device包含一个或者多个Service,此处的Service代表设备的一种能力,一个具体的设备可能有多种能力。一个Service包含一系列property,action:

  • property表示该service当前状态,property具有名称,数据类型,默认值,以及其值改变时是否触发事件
  • action表示service可以控制的动作 撰写一份xml格式的设备功能描述文档,用于描述设备具体功能,可以参考demo中附带的ddd_SmartSocket.xml(小米智能插座)以及ddd_AuxAircondition.xml(奥克斯空调)。

3. 生成设备代码

撰写完设备功能描述文档后,使用提供的脚本codegenerator.jar,运行如下命令

    java -jar codegenerator.jar src/main/assets/ddd_SmartSocket.xml

运行时将最后一个变量替换为自己xml文档的相对路径,运行成功后将生成SmartSocketBase.java以及SmartSocketBaseService.java两个文件(生成文件数量与xml中定义的service数量有关)

使用SDK开发App

接下来将简要介绍如何配置和使用mijiaSDK开发自己的App,也可以参考其中的demo。

1. 配置AndroidManifest.xml

  • mijiaSDK支持的最低android版本
     <uses-sdk
        android:minSdkVersion="16"
        android:targetSdkVersion="18" />
  • mijiaSDK需要的权限列表
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE"/>
    <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE"/>
    <uses-permission android:name="android.permission.CONNECTIVITY_INTERNAL"/>​
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.USE_CREDENTIALS"/>
    <uses-permission android:name="android.permission.AUTHENTICATE_ACCOUNTS"/>

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.CHANGE_WIFI_MULTICAST_STATE"/>

    <!--小米帐号SDK需要的权限-->   
    <uses-permission android:name="com.xiaomi.permission.AUTH_SERVICE" />

    <!--Mipush需要的权限,这里的com.mi.test改成app的包名-->   
    <permission
        android:name="com.mi.test.permission.MIPUSH_RECEIVE"
        android:protectionLevel="signature" />
    <uses-permission android:name="com.mi.test.permission.MIPUSH_RECEIVE" />
  • mijiaSDK需要配置的android组件(这些组件已经在SDK中声明过了,在自己的APP中可以不再声明)
        <!--小米帐号SDK的组件-->
        <activity
            android:name="com.xiaomi.account.openauth.AuthorizeActivity"

                <action android:name="miot.aidl.IBinderPool"/>
            </intent-filter>
        </service>

2. 初始化SDK

这里简单描述如何初始化mijiaSDK,可以参考demo中TestApplication.java

  • 首先初始化MiotManager:
    MiotManager.getInstance().initialize(getApplicationContext());
  • 然后将小米帐号处的AppId,AppKey设置到SDK中:
    AppConfiguration appConfig = new AppConfiguration();
    appConfig.setAppId(AppConfig.APP_ID);
    appConfig.setAppKey(AppConfig.APP_KEY);
    MiotManager.getInstance().setAppConfig(appConfig);
  • 接着将App需要处理的设备配置到SDK中:
    try {
        DeviceModel smartSocket = DeviceModelFactory.createDeviceModel(TestApplication.this,
                TestConstants.CHUANGMI_PLUG_V1,
                TestConstants.CHUANGMI_PLUG_V1_URL,
                SmartSocketBase.class);
        MiotManager.getInstance().addModel(smartSocket);
    } catch (DeviceModelException e) {
        e.printStackTrace();
    }

方法createDeviceModel中的参数依次为:context;model:云端注册的设备model;url:xml格式的profile文档,需要放到项目assets目录下;clazz(Class<?>):之前生成的设备代码的class

  • 最后bindService:
    MiotManager.getInstance().open();

如果返回值为0,则为绑定成功。退出应用时需要unBind:

    MiotManager.getInstance().close()

同上,返回值为0,则为解绑成功

  • 将用户信息保存到Service中,可以参考demo中AccountActivity.java
private void processAuthResult(XiaomiOAuthResults results) {
    String accessToken = results.getAccessToken();
    String expiresIn = results.getExpiresIn();
    String scope = results.getScopes();
    String state = results.getState();
    String tokenType = results.getTokenType();
    String macKey = results.getMacKey();
    String macAlgorithm = results.getMacAlgorithm();

    ...

    new XiaomiAccountGetPeopleInfoTask(accessToken, expiresIn, macKey, macAlgorithm,
            new XiaomiAccountGetPeopleInfoTask.Handler() {
                @Override
                public void onSucceed(People people) {
                    Log.d(TAG, "XiaomiAccountGetPeopleInfoTask OK");
                    try {
                        MiotManager.getPeopleManager().savePeople(people);
                        initUserInfo();
                    } catch (MiotException e) {
                        e.printStackTrace();
                    }
                }

                @Override
                public void onFailed() {
                    Log.d(TAG, "XiaomiAccountGetPeopleInfoTask Failed");
                }
            }).execute();
}

3. 开发设备相关功能

SDK目前提供了如下功能:

  1. 获取设备列表:获取设备
  2. 快连设备:用于将新设备联网,也就是快连(目前快连默认完成绑定设备)
  3. 绑定设备: 完成设备与用户的帐号绑定关系
  4. 解绑设备:允许用户解除与设备的绑定关系
  5. 分享设备:用户可以将设备分享给其他人(目前仅小米帐号)
  6. 控制设备:包括获取设备状态、下发指令和订阅设备事件

获取设备列表

调用DeviceManager中的设备发现接口,可以参考demo中MiDeviceManager.java相关代码

    try {
        MiotManager.getDeviceManager().getRemoteDeviceList(new DeviceManager.DeviceHandler() {
            @Override
            public void onSucceed(List<AbstractDevice> devices) {
                //TODO
            }

            @Override
            public void onFailed(int errCode, String description) {
                //TODO
            }
        });
    } catch (MiotException e) {
        e.printStackTrace();
    }

快连设备

  • 发现待连接设备 调用DeviceManager中的设备扫描接口,可以参考demo中MiDeviceManager.java相关代码
    List<DiscoveryType> types = new ArrayList<>();
    types.add(DiscoveryType.MIOT_WIFI);
    try {
        MiotManager.getDeviceManager().startScan(types, new DeviceManager.DeviceHandler() {
            @Override
            public void onSucceed(List<AbstractDevice> devices) {
                //TODO
            }

            @Override
            public void onFailed(int errCode, String description) {
                //TODO
            });
    } catch (MiotException e) {
        e.printStackTrace();
    }

需要注意的是,Android6.0加入运行时权限,扫描Wifi设备需要运行时权限的支持,关于运行时权限,详见google文档,demo中有一个简单的示例,代码如下所示:

    private static final int REQUEST_LOCATION_PERMISSION = 10000;

    @TargetApi(23)
    private boolean hasPermission() {
        return Build.VERSION.SDK_INT < 23 ||
                ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED &&
                        ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED;
    }

    @TargetApi(23)
    private void requestPermission() {
        if (Build.VERSION.SDK_INT < 23) {
            return;
        }
        String[] permissions = new String[]{
                Manifest.permission.ACCESS_FINE_LOCATION,
                Manifest.permission.ACCESS_COARSE_LOCATION
        };
        ActivityCompat.requestPermissions(this, permissions, REQUEST_LOCATION_PERMISSION);
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        switch (requestCode) {
            case REQUEST_LOCATION_PERMISSION:
                if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    MiDeviceManager.getInstance().startScan();
                } else {
                    Log.e(TAG, "on permission to scan device");
                }
        }
    }
  • 配置快连图标和文案:将快连图标放置到自己工程的res/drawable-xxhdpi目录下,并命名为kuailian_miio_icon.png。在strings.xml文件添加
    <string name="common_mieda_device">(文案)</string>
  • 快连设备,获取到设备列表后,如果设备是待连接的设备,可以调用以下方法连接到云端,具体可以参考demo中DeviceActivity.class:
private void connectDevice(AbstractDevice device) {
    try {
        MiotManager.getDeviceConnector().connectToCloud(device, new CompletionHandler() {
            @Override
            public void onSucceed() {
                Logger.d(TAG, "connect device onSucceed");
            }

            @Override
            public void onFailed(int errCode, String description) {
                Logger.e(TAG, "connect device onFailed: " + errCode + description);
            }
        });
    } catch (MiotException e) {
        e.printStackTrace();
    }
}

绑定设备

绑定设备,即为将设备绑定到一个用户帐号下,只能用于未绑定的广域网设备(目前快连过程中会默认绑定设备)

    try {
        MiotManager.getDeviceManager().takeOwnership(abstractDevice, new CompletionHandler() {
            @Override
            public void onSucceed() {
                Logger.d(TAG, "takeOwnership onSucceed");
            }

            @Override
            public void onFailed(int errCode, String description) {
                Logger.e(TAG, "takeOwnership onFialed: " + errCode + " " + description);
            }
        });      
    } catch (MiotException e) {
        e.printStackTrace();
    }

解绑设备

解绑设备,即为从用户名下删除该设备,并重置该设备

    try {
        MiotManager.getDeviceManager().disclaimOwnership(abstractDevice, new CompletionHandler() {
            @Override
            public void onSucceed() {
                Logger.d(TAG, "disclaimOwnership onSucceed");
            }

            @Override
            public void onFailed(int errCode, String description) {
                Logger.e(TAG, "disclaimOwnership onFialed: " + errCode + " " + description);
            }
        });      
    } catch (MiotException e) {
        e.printStackTrace();
    }

分享设备

  • 将设备分享给其他人
    try {
        MiotManager.getDeviceManager().shareDevice(mAbstractDevice, userId, new CompletionHandler() {
            @Override
            public void onSucceed() {
                Logger.d(TAG, "shareDevice onSucceed");
            }

            @Override
            public void onFailed(int errCode, String description) {
                Logger.e(TAG, "shareDevice onFailed: " + errCode + " " + description);
            }
        });
    } catch (MiotException e) {
        e.printStackTrace();
    }

其中userId为用户小米帐号ID。

  • 取消分享
    try {
        MiotManager.getDeviceManager().cancelShare(mAbstractDevice, userId, new CompletionHandler() {
            @Override
            public void onSucceed() {
                Logger.d(TAG, "cancelShare onSucceed");
            }

            @Override
            public void onFailed(int errCode, String description) {
                Logger.e(TAG, "cancelShare onFailed: " + errCode + " " + description);
            }
        });
    } catch (MiotException e) {
        e.printStackTrace();
    }
  • 查看设备被分享用户列表
    try {
        MiotManager.getDeviceManager().querySharedUsers(mAbstractDevice, new CommonHandler<List<SharedUser>>() {
            @Override
            public void onSucceed(List<SharedUser> result) {
                Logger.d(TAG, "querySharedUsers onSucceed");
                ...
            }

            @Override
            public void onFailed(int errCode, String description) {
                Logger.e(TAG, "querySharedUsers onFailed: " + errCode + " " + description);
            }
        });
    } catch (MiotException e) {
        e.printStackTrace();
    }
  • 被分享者查看设备分享邀请
    try {
        MiotManager.getDeviceManager().querySharedRequests(new CommonHandler<List<SharedRequest>>() {
            @Override
            public void onSucceed(List<SharedRequest> result) {
                Logger.d(TAG, "querySharedRequests onSucceed");
                ...
            }

            @Override
            public void onFailed(int errCode, String description) {
                Logger.e(TAG, "querySharedRequests: " + errCode + description);
            }
        });
    } catch (MiotException e) {
        e.printStackTrace();
    }
  • 接受或者拒绝设备分享邀请
    sharedRequest.setShareStatus(ShareStatus.accept);
    try {
        MiotManager.getDeviceManager().replySharedRequest(sharedRequest, new CompletionHandler() {
            @Override
            public void onSucceed() {
                Logger.d(TAG, "replySharedRequest onSucceed");
            }

            @Override
            public void onFailed(int errCode, String description) {
                Logger.e(TAG, "replySharedRequest: " + errCode + description);
            }
        });
    } catch (MiotException e) {
        e.printStackTrace();
    }

其中ShareStatus中accept为接受邀请,reject为拒绝邀请。

控制设备

这里以小米插座为例,简要说明一下,具体可以参见demo中SmartsocketActivity

  • 获取设备状态
public void getProperties() {
    try {
        mSmartSocketBaseService.getProperties(new SmartSocketBaseService.GetPropertiesCompletionHandler() {
            @Override
            public void onSucceed(final Boolean usbStatus, final Boolean powerStatus) {
                Logger.d(TAGString.format("getProperties usbStatus=%s powerStatus=%s", usbStatus, powerStatus));
                ...
            }

            @Override
            public void onFailed(int errCode, String description) {
                Logger.e(TAGString.format("getProperties Failed, code: %d %s", errCode, description));
            }
        });
    } catch(MiotException e) {
        e.printStackTrace();
    }
}
  • 下发命令
public void setPlugOn() {
    try {
        mSmartSocketBaseService.setPlugOn(new CompletionHandler() {
            @Override
            public void onSucceed() {
                Logger.d(TAG, "setPlugOn OK");
                ...
            }

            @Override
            public void onFailed(int errCode, String description) {
                Logger.e(TAGString.format("setPlugOn Failed, code: %d %s", errCode, description));
            }
        });
    } catch (MiotException e) {
        e.printStackTrace();
    }
}
  • 订阅状态变化 需要注意的是订阅部分使用的是MiPush的服务,其与应用包名绑定。
public void subscribeNotification() {
