Class Overview
Network fetcher that uses Volley as its backend. The request being made will bypass Volley's cache.
Volley does not allow access to a InputStream. Therefore, responses will be passed along as complete byte arrays, which will not allow for progressive JPEG streaming.

Public Methods
public VolleyNetworkFetcher.VolleyNetworkFetchState createFetchState (Consumer<EncodedImage> consumer, ProducerContext context)
public void fetch (VolleyNetworkFetcher.VolleyNetworkFetchState fetchState, NetworkFetcher.Callback callback)
public Map<String, String> getExtraMap (VolleyNetworkFetcher.VolleyNetworkFetchState 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 (VolleyNetworkFetcher.VolleyNetworkFetchState 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 |
