HarmonyOS 鸿蒙Next中使用Wear Engine查询已连接的穿戴设备列表出错

HarmonyOS 鸿蒙Next中使用Wear Engine查询已连接的穿戴设备列表出错 要使用Wear Engine服务，进行手机侧应用的开发测试

1、按照文档，已经完成了申请Wear Engine服务，申请结果如下：

cke_3508.png

cke_3862.png

2、已在工程中entry模块的module.json5文件中，完成Client ID配置。

3、代码中调用

@State deviceClient: wearEngine.DeviceClient = wearEngine.getDeviceClient(this.getUIContext().getHostContext());

this.deviceClient.getConnectedDevices().then(devices => {
  this.deviceList = devices;
  this.printContent += `Succeeded in getting devices, devices number is ${devices.length}` + '\n';
  console.info(`Succeeded in getting devices, devices number is ${devices.length}`);
}).catch((error: BusinessError) => {
  this.printContent += `Failed to get devices. Code is ${error.code}, message is ${error.message}` + '\n';
  console.error(`Failed to get devices. Code is ${error.code}, message is ${error.message}`);
})

提示：getConnectedDevices error is {“code”:1008509999,“name”:"",“message”:“Internal error.”}

4、测试设备为：Pura 70 Pro HarmonyOS 5.1.0 ,API版本17。

导出hilog日志到当前目录。

hdc file recv data/log/hilog/ ./

提供问题发生时间点前后完整的hilog日志。

日志文件附在下方，辛苦。

你好，hilog日志如附件。

在鸿蒙Next中，使用Wear Engine查询设备列表出错可能由权限未配置或引擎初始化异常导致。请检查ohos.permission.DISTRIBUTED_DATASYNC权限是否在module.json5中声明，并确认设备已开启蓝牙且处于可发现状态。排查Wear Engine API调用参数是否正确，避免空指针或类型错误。

从您的描述来看，Wear Engine服务申请和配置已基本完成，但调用getConnectedDevices时返回错误码1008509999（内部错误）。以下是排查建议：

  1. 权限检查：确保在module.json5中已声明必要的权限，例如ohos.permission.DISTRIBUTED_DATASYNC，用于设备发现和通信。

  2. 服务依赖验证：确认Wear Engine服务已正确集成到项目中，依赖项版本与HarmonyOS Next API 17兼容。检查package.json中@ohos/wearEngine的版本是否支持当前系统。

  3. 上下文传递：getDeviceClient使用的HostContext需确保来自有效的UI组件上下文。建议在aboutToAppear或组件初始化时获取上下文，避免空值。

  4. 设备连接状态：确保测试手机与穿戴设备已通过蓝牙或Wi-Fi正常配对并连接。系统设置中应显示设备为“已连接”状态。

  5. 错误日志分析：通过hilog查看详细错误日志，使用console.error输出更完整的堆栈信息，辅助定位内部错误的具体原因。

  6. API兼容性：HarmonyOS 5.1.0（API 17）可能与Wear Engine部分接口存在适配问题，建议检查是否有已知的版本兼容性更新或补丁。

若以上步骤仍无法解决，建议提供更详细的错误日志或尝试在真机调试模式下复现问题。
