Client API. The Codename One framework your app is built on: this runs on the device, not in a backend.

public class NetworkTransport

Object
NetworkTransport

The application’s RpcTransport: each request goes through the NetworkManager queue as a ConnectionRequest, waiting with addToQueueAndWait, so a call from the EDT keeps the UI responsive. Headers added with header go on every request, which is how a provider’s API key is passed.

Not shared with the backend, which has com.codename1.backend.WebRpcTransport instead.

Constructors

Methods

`public` `NetworkTransport header(String name, String value)`	Adds a header sent with every request, for instance an API key.
`public` `NetworkTransport timeout(int millis)`	The request timeout in milliseconds; 30 seconds by default.
