public HttpUrlConnectionNetworkFetcher(String userAgent, int httpConnectionTimeout)

public HttpUrlConnectionNetworkFetcher(String userAgent, Map<String, String> requestHeaders, int httpConnectionTimeout)

Public Methods

public HttpUrlConnectionNetworkFetcher.HttpUrlConnectionNetworkFetchState createFetchState(Consumer<EncodedImage> consumer, ProducerContext context)

public void fetch(HttpUrlConnectionNetworkFetcher.HttpUrlConnectionNetworkFetchState fetchState, NetworkFetcher.Callback callback)

public Map<String, String> getExtraMap(HttpUrlConnectionNetworkFetcher.HttpUrlConnectionNetworkFetchState fetchState, int byteSize)

Gets a map containing extra parameters to pass to the listeners.

Returning map is optional and is useful for instrumentation purposes.

This map won't be modified by the caller.

Parameters

| fetchState | the fetch-specific state | | byteSize | size of the data in bytes |

Returns
  • a map with extra parameters

public void onFetchCompletion(HttpUrlConnectionNetworkFetcher.HttpUrlConnectionNetworkFetchState fetchState, int byteSize)

Called after the fetch completes.

Implementing this method is optional and is useful for instrumentation purposes.

Parameters

| fetchState | the fetch-specific state | | byteSize | size of the data in bytes |
