CaaS Engine是华为依托畅连业务通信能力，面向应用开发者和硬件开发者提供的开放接口，帮助开发者实现应用内实时共享的能力，助力用户即刻分享应用内允许共享的内容。
在这个Codelab中，你将创建Demo Project，并将CaaS Engine的SDK集成到Demo Project中，以及完成CaaS Engine服务的整体流程搭建。
集成CaaS Engine能力，需要完成以下准备工作：
向项目中的build.gradle中配置仓库：
buildscript {
repositories {
google()
jcenter()
maven {url 'http://developer.huawei.com/repo/'}
}
}
allprojects {
repositories {
maven {url 'http://developer.huawei.com/repo/'}
google()
jcenter()
}
}
在工程APP目录中的build.gradle中添加如下依赖：
repositories {
flatDir {
dirs 'libs'
}
}
dependencies {
implementation group: 'com.huawei.caaskit', name: 'caaskitlite', version: '1.0.1.400', ext: 'aar'
}
点击同步工程按钮，进行工程同步，如下图所示：
同步成功后，如下图所示：
在自身应用AndroidManifest.xml中添加开发者联盟创建应用时生成的appid信息，name为"com.huawei.hms.client.appid"，value为"appid=*"，*用自己注册的appid。权限申请，请依照《开发指南》中"开发准备"的详细说明来完成。
CaaS服务的初始化封装代码如下：CaasKitHelper.java
public class CaasKitHelper {
private static final String TAG = "CaasKitHelper";
private static CaasKitHelper sCaasKitHelper;
private HwCaasServiceManager mHwCaasServiceManager;
private HwCaasHandler mHwCaasHandler;
private Context mContext;
private boolean mIsSendShowFail;
private boolean mIsCaasKitInit;
private boolean mIsHasCaaSContacts = false;
private HwCallStateCallBack mCallStateCallBack = new HwCallStateCallBack() {
@Override
public void notifyCallState(HwCaasUtils.CallState state) {
Log.d(TAG, "callState: " + state);
}
};
private HwCaasServiceCallBack mCallBack = new HwCaasServiceCallBack() {
@Override
public void initSuccess(HwCaasHandler handler) {
...
}
@Override
public void initFail(int retCode) {
...
}
@Override
public void releaseSuccess() {
...
}
};
private CaasKitHelper() {
mContext = CaasKitApplication.getContext();
}
public synchronized static CaasKitHelper getInstance() {
if (sCaasKitHelper == null) {
sCaasKitHelper = new CaasKitHelper();
}
return sCaasKitHelper;
}
public void caasKitInit() {
Log.d(TAG, "caasKitInit.");
if (!mIsCaasKitInit) {
// initialize mHwCaasServiceManager instance.
mHwCaasServiceManager = HwCaasServiceManager.init();
// initialize HwCaasHandler instance through handlerType.
mHwCaasServiceManager.initHandler(mContext, HwCaasUtils.SCREEN_SHARING_TYPE, mCallBack);
mIsCaasKitInit = true;
}
}
}
在合适的位置进行调用：CaasKitDemoActivity.java

super.onCreate(savedInstanceState);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_caaskitdemo);
CaasKitHelper.getInstance().caasKitInit();
}
}
CaasKitHelper.java
public class CaasKitHelper {
private static final String TAG = "CaasKitHelper";
private static final int VIEWHEIGHT = 248;
private static final int VIEWWIDTH = 256;
private static final int LOCATION_X = 102;
private static final int LOCATION_Y = 140;
private static CaasKitHelper sCaasKitHelper;
private HwCaasServiceManager mHwCaasServiceManager;
private HwCaasHandler mHwCaasHandler;

}
};
private HwCaasServiceCallBack mCallBack = new HwCaasServiceCallBack() {
@Override
public void initSuccess(HwCaasHandler handler) {
// callback after successful initialization of HwCaasHandler.
mHwCaasHandler = handler;
if (mHwCaasHandler != null) {
// 显示在对端呼入界面的来电应用名称，必须设置，不然畅连入口无法显示
mHwCaasHandler.setCallerAppName("Application");
// 联系人选择悬浮窗 也可以选择全屏列表（类似系统联系人界面）
mHwCaasHandler.setContactViewStyle(HwCaasUtils.ContactsViewStyle.FULL_SCREEN);
// 当选择悬浮窗时，可设置悬浮窗的大小和初始位置，选择全屏联系人界面了这些设置就不需要了
// mHwCaasHandler.setContactViewStyle(HwCaasUtils.ContactsViewStyle.FLOAT_VIEW);
