问题描述
是否有可能从一个Android应用程序使上下文订阅猎户座语境经纪资源呢？对于NGSI10基本操作（updateContext和queryContext）我supose任何普通的Android REST客户端可以使用，但如何才能通过subscribeContext订阅？
Is it possible to make context subscriptions to Orion Context Broker resources from an Android application? For NGSI10 basic operations (updateContext and queryContext) I supose that any common android rest client can be used, but how can we subscribe through subscribeContext?
在此先感谢。
