Retrofit2

A Retrofit 2 Converter. Factory for Kotlin serialization.

The Retrofit class generates an implementation of the GitHubService interface. The relative URL of the resource is specified in the annotation. A request URL can be updated dynamically using replacement blocks and parameters on the method. A corresponding parameter must be annotated with Path using the same string. The object will also be converted using a converter specified on the Retrofit instance. If no converter is added, only RequestBody can be used.

Adapts a Call with response type R into the type of T. Creates CallAdapter instances based on the return type of the service interface methods. Creates Converter instances based on a type and target usage. Retrofit adapts a Java interface to HTTP calls by using annotations on the declared methods to define how requests are made. Build a new Retrofit. Call An invocation of a Retrofit method that sends a request to a webserver and returns a response. Factory Creates CallAdapter instances based on the return type of the service interface methods.

Every method of an interface represents one possible API call. The return value wraps the response in a Call object with the type of the expected result. You can use replacement blocks and query parameters to adjust the URL. With the help of the Path annotation on the method parameter, the value of that parameter is bound to the specific replacement block. Query parameters are added with the Query annotation on a method parameter. They are automatically added at the end of the URL. The Body annotation on a method parameter tells Retrofit to use the object as the request body for the call.

Additionally, it provides functionality for multipart request body and file uploads. Now we can build the interface for the API that will actually fetch the data from the server. Now we will make a little wrapper class for our API to keep the Retrofit initialization code wrapped up nicely. Calling enqueue tells Retrofit to make that call on a background thread and return the result to the callback that we're creating here. However, you don't need your own model class.

Calls may be executed synchronously with execute , or asynchronously with enqueue retrofit2. In either case the call can be canceled at any time with cancel. A call that is busy writing its request or reading its response may receive a IOException ; this is working as designed. Throws: IOException - if a problem occurred talking to the server. RuntimeException - and subclasses if an unexpected error occurs creating the request or decoding the response. It is an error to execute or enqueue a call more than once. An attempt will be made to cancel in-flight calls, and if the call has not yet been executed it never will be.

ArrayAdapter ; import android. AppCompatActivity ; import android. A DialogFragment is used to enter the credentials for authentication. With the help of this annotation, we can provide the URL for this request. Branches Tags. Authentication with OkHttp interceptors The above method only adds the credentials, if you request your user details. This is needed to specify the owner and the repository name for which the issues should be requested. Licensed under the Apache License, Version 2. For the title of the channel and the several item-elements, we can directly point to the specific elements within the channel-element. Retrofit 1. GsonBuilder ; import java.

It's time to kick off a brand-new Retrofit topic and mini series: call adapters. In this first introductory tutorial you'll learn what call adapters are and how you can utilize them in Retrofit.

Because Kotlin serialization is so flexible in the types it supports, these converters assume that they can handle all types. Retrofit can also be extended by adapters to get involved with other libraries like RxJava 2. By default, Retrofit will give you sane defaults for your platform but it allows for customization. ArrayAdapter ; import android. Notifications Fork 59 Star 1k. You can select a repository from a drop-down field and list the issues that are assigned to the user for the selected repository. This allows us to change the URL for each request dynamically. The first method would be to manipulate the header for the request with the help of annotations. Create data model Create the following two data classes which are used to store the response data from Stackoverflow. You switched accounts on another tab or window. Callback Communicates responses from a server or offline requests.
