Direct Known Subclasses:
SyncHttpClient
```
public class AsyncHttpClient extends java.lang.Object
```
The AsyncHttpClient can be used to make asynchronous GET, POST, PUT and DELETE HTTP requests in your Android applications. Requests can be made with additional parameters by passing a RequestParams instance, and responses can be handled by passing an anonymously overridden ResponseHandlerInterface instance.For example:
```
 AsyncHttpClient client = new AsyncHttpClient();  client.get("http://www.google.com", new ResponseHandlerInterface() {      @Override      public void onSuccess(String response) {          System.out.println(response);      }  });  
```
