Class AsyncHttpClient

java.lang.Object

com.loopj.android.http.AsyncHttpClient

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 AsyncHttpResponseHandler() {
     @Override
     public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
          System.out.println(response);
     }
     @Override
     public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable
 error)
 {
          error.printStackTrace(System.out);
     }
 });
