程序包 ohos.distributedschedule.interwork

Provides interfaces and classes for registering and unregistering device state callbacks, obtaining information about all devices or a specified device on the distributed network, querying application information, and initializing the distributed execution framework. You can use this package to perform the following operations:

• Call DeviceManager#registerDeviceStateCallback(IDeviceStateCallback) to register device state callbacks so that your application can receive notifications when a device on the distributed network becomes online or offline and call DeviceManager#unregisterDeviceStateCallback(IDeviceStateCallback) to unregister these callbacks.
• Call DeviceManager#getDeviceList(int) to obtain information about all devices on the distributed network.
• Call DeviceManager#getDeviceInfo(String) to obtain information about a specified device on the distributed network.
• Call DeviceManager#queryRemoteAbilityByIntent(Intent) to obtain AbilityInfo information about a non-HarmonyOS application on the distributed network.
• Call DeviceManager#initDistributedEnvironment(String, IInitCallback) to initialize the distributed execution framework on a device with a callback specified to notify your application of the initialization result. After the cross-device task is complete, call DeviceManager#unInitDistributedEnvironment(String, IInitCallback) to deactivate the distributed execution framework.
