服务接入华为分享开发指导

代码集成

1.集成IDL接口，用于建立分享方与华为分享的交互通道，完成后续服务分享过程。

在“java”目录同级目录创建“idl”接口目录（可手动添加或通过DevEco Studio创建）：com/huawei/hwshare/third（固定路径），然后创建名为IHwShareCallback.idl和IHwShareService.idl的IDL文件。

IHwShareCallback.idl :interface com.huawei.hwshare.third.IHwShareCallback {    [oneway] void notifyState([in] int state);}IHwShareService.idl :sequenceable ohos.interwork.utils.PacMapEx;interface com.huawei.hwshare.third.IHwShareCallback;interface com.huawei.hwshare.third.IHwShareService {    int startAuth([in] String appId, [in] IHwShareCallback callback);    int shareFaInfo([in] PacMapEx pacMapEx);}

2.创建ShareFaManager类，用于管理分享方与华为分享的连接通道和数据交互。

import com.huawei.hwshare.third.HwShareCallbackStub;import com.huawei.hwshare.third.HwShareServiceProxy;import ohos.aafwk.ability.IAbilityConnection;import ohos.aafwk.content.Intent;import ohos.app.Context;import ohos.bundle.ElementName;import ohos.eventhandler.EventHandler;import ohos.eventhandler.EventRunner;import ohos.interwork.utils.PacMapEx;import ohos.rpc.IRemoteObject;import ohos.rpc.RemoteException;import ohos.hiviewdfx.HiLog;import ohos.hiviewdfx.HiLogLabel;public class ShareFaManager {    private static final HiLogLabel LABEL_LOG = new HiLogLabel(3, 0xD000F00, "ShareFa");    private static final String LOG_FORMAT = "%{public}s: %{public}s";    public static final String HM_FA_ICON = "ohos_fa_icon";    public static final String HM_FA_NAME = "ohos_fa_name";    public static final String HM_ABILITY_NAME = "ohos_ability_name";    public static final String HM_BUNDLE_NAME = "ohos_bundle_name";    public static final String SHARING_FA_TYPE = "sharing_fa_type";    public static final String SHARING_THUMB_DATA = "sharing_fa_thumb_data";    public static final String SHARING_CONTENT_INFO = "sharing_fa_content_info";    public static final String SHARING_EXTRA_INFO = "sharing_fa_extra_info";    private static final String TAG = "ShareHmFaManager";    private static final String SHARE_PKG_NAME = "com.huawei.android.instantshare";    private static final String SHARE_ACTION = "com.huawei.instantshare.action.THIRD_SHARE";    private static final long UNBIND_TIME = 20*1000L;    private Context mContext;    private String mAppId;    private PacMapEx mSharePacMap;    private static ShareFaManager sSingleInstance;    private HwShareServiceProxy mShareService;    private boolean mHasPermission = false;    private EventHandler mHandler = new EventHandler(EventRunner.getMainEventRunner());    private final IAbilityConnection mConnection = new IAbilityConnection() { @Override public void onAbilityConnectDone(ElementName elementName, IRemoteObject iRemoteObject, int i) { HiLog.error(LABEL_LOG, LOG_FORMAT, TAG, "onAbilityConnectDone success."); mHandler.postTask(()->{     mShareService = new HwShareServiceProxy(iRemoteObject);  try {      mShareService.startAuth(mAppId, mFaCallback);  } catch (RemoteException e) {      HiLog.error(LABEL_LOG, LOG_FORMAT, TAG, "startAuth error.");  }  });     }     @Override     public void onAbilityDisconnectDone(ElementName elementName, int i) {  HiLog.info(LABEL_LOG, LOG_FORMAT, TAG, "onAbilityDisconnectDone.");  mHandler.postTask(()->{      mShareService = null;      mHasPermission = false;      });     }    };    private Runnable mTask = () -> { if (mContext != null && mShareService != null) {     mContext.disconnectAbility(mConnection);     mHasPermission = false;     mShareService = null; }    };    private final HwShareCallbackStub mFaCallback = new HwShareCallbackStub("HwShareCallbackStub") { @Override public void notifyState(int state) throws RemoteException {     mHandler.postTask(()->{  HiLog.info(LABEL_LOG, LOG_FORMAT, TAG, "notifyState: " + state);  if (state == 0) {      mHasPermission = true;      if (mSharePacMap != null) {   shareFaInfo();      }  }     }); }    };    /**     * 单例模式获取ShareFaManager的实例对象     *     * @param context 程序Context     * @return ShareFaManager实例对象     */    public static synchronized ShareFaManager getInstance(Context context) { if (sSingleInstance == null && context != null) {     sSingleInstance = new ShareFaManager(context.getApplicationContext()); } return sSingleInstance;    }    private ShareFaManager(Context context) { mContext = context;    }    private void shareFaInfo() { if (mShareService == null) {     return; } if (mHasPermission) {     HiLog.info(LABEL_LOG, LOG_FORMAT, TAG, "start shareFaInfo.");     try {  mShareService.shareFaInfo(mSharePacMap);  mSharePacMap = null;     } catch (RemoteException e) {  HiLog.error(LABEL_LOG, LOG_FORMAT, TAG, "shareFaInfo error.");     } } // 不使用时断开 mHandler.postTask(mTask, UNBIND_TIME);    }    /**     * 用于分享服务     *     * @param appId 开发者联盟网站创建原子化服务时生成的appid     * @param pacMap 服务信息载体     */    public void shareFaInfo(String appId, PacMapEx pacMap) { if (mContext == null) {     return; } mAppId = appId; mSharePacMap = pacMap; mHandler.removeTask(mTask); shareFaInfo(); bindShareService();    }    private void bindShareService() { if (mShareService != null) {     return; } HiLog.error(LABEL_LOG, LOG_FORMAT, TAG, "start bindShareService."); Intent intent = new Intent(); Operation operation = new Intent.OperationBuilder()     .withDeviceId("")     .withBundleName(SHARE_PKG_NAME)     .withAction(SHARE_ACTION)     .withFlags(Intent.FLAG_NOT_OHOS_COMPONENT)     .build(); intent.setOperation(operation); mContext.connectAbility(intent, mConnection);    }}

效果如图所示

代码实现

xml代码绘画一个text按钮，代码如下

java 代码给按钮实现点击事件，需要注意的必选参数，代码如下
