A android async http json third-party library called android-async-http helps handle the entire process of sending and parsing network requests for us in a more robust and easy-to-use way.

If you are upgrading from previous versions, you need to change these import statements for the Header class from:. If you have any other import statements that start with org. Now, we just create an AsyncHttpClientand then execute a request specifying an anonymous class as a callback:. This will automatically execute the request asynchronously android async http json fire the onSuccess when the response returns a success code and onFailure if the response does not.

Assuming the callback uses JsonHttpResponseHandlerthe request will be sent out with the appropriate parameters passed in the query string and then the response can be parsed as JSON and made available within onSuccess. This approach works also for nested JSON objects too. In addition, many API requests require authentication in order to identify the user making the request.

This is typically done with a standard OAuth process for authentication. Fortunately, there are several OAuth libraries out there to simplify the process of authentication such as scribe and signpost, android async http json.

You can explore several examples of using scribe or signpost to authenticate. We have also created a meta-library to make this process as simple as possible called android-oauth-handler and a skeleton app to act as a template for a simple rest client called android-rest-client-template.

Using these wrappers, you can then send an API request and properly process the response using code like this:, android async http json. Note that as shown above you should also handle failure cases with JsonHttpResultHandler using the onFailure method so your application is robust to "losing internet" and user doesn't become confused with unexpected results.
