HarmonyOS-鸿蒙app开发 —基于java_华为分享接入_服务接入华为分享开发指导

服务接入华为分享开发步骤（HarmonyOS侧）

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。

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。

.withAction(SHARE_ACTION)

.withFlags(Intent.FLAG_NOT_OHOS_COMPONENT)

.build();

intent.setOperation(operation);

mContext.connectAbility(intent, mConnection);

}

}

封装服务分享数据，调用ShareFaManager封装的接口完成服务的分享。

PacMapEx pacMap = new PacMapEx();

pacMap.putObjectValue(ShareFaManager.SHARING_FA_TYPE, 0);

pacMap.putObjectValue(ShareFaManager.HM_BUNDLE_NAME, getBundleName());

pacMap.putObjectValue(ShareFaManager.SHARING_EXTRA_INFO, “xxxxxxxx”);

pacMap.putObjectValue(ShareFaManager.HM_ABILITY_NAME, XxxAbility.class.getName());

pacMap.putObjectValue(ShareFaManager.SHARING_CONTENT_INFO, “xxxxxxx”);

pacMap.putObjectValue(ShareFaManager.SHARING_THUMB_DATA, picByte);

pacMap.putObjectValue(ShareFaManager.HM_FA_ICON, iconByte);

pacMap.putObjectValue(ShareFaManager.HM_FA_NAME, “FAShareDemo”);

// 第一个参数为appid，在华为AGC创建原子化服务时自动生成。

ShareFaManager.getInstance(MainAbilitySlice.this).shareFaInfo(“xxxxxxxxxx”, pacMap);

编译HAP包后进行调试。

准备两台HarmonyOS手机，且其系统软件版本不低于HarmonyOS 2.0。

配置真机调试（具体配置方式请参见真机调试指导），参考用户业务流程进行调试。
