NetworkFetchProducer

extends Object
implements Producer<T>

| java.lang.Object | | ↳ | com.facebook.imagepipeline.producers.NetworkFetchProducer |

Class Overview

A producer to actually fetch images from the network.

Downloaded bytes may be passed to the consumer as they are downloaded, but not more often than #TIME_BETWEEN_PARTIAL_RESULTS_MS.

Clients should provide an instance of NetworkFetcher to make use of their networking stack. Use HttpUrlConnectionNetworkFetcher as a model.
