RestClient

REST Client is an android application to test Restful web services. It can be used to test variety of HTTP communications.
REST Client is designed for Android Environment. A REST-based API typically manifests itself by specifying a set of methods constrained by the HTTP protocol (GET, POST, PUT.) that can be applied to resources expressed as URIs. Return values are presented using the typical HTTP status code mechanism along with content distinguished by type.We use web services to exchange data with the server over HTTPS via Rest client .We should use a complex architecture that uses a combination of a Content Provider and a Service, so our data was more persistent between app restarts. Content Provider checks its local database, if the content is not there it sends an Intent to a service which fetches the content, inserts it into the Content Provider, then the Content Provider calls back to the Activity (with a Content Observer) and the Activity can carry on. The Content Provider exposes simple methods, Get, Put, and Post. REST Client Save, update, and load requests. The requests are sent through HTTP methods (GET, POST, and PUT) and the response is show in XML, WEB and JSON.
Each REST operation is executed on a resource identified by a request URL. The url is send, its checks and validate the url. The request is send by using http methods (Get, Post, and Put) and show responses. Request headers used in REST service calls are Content-Type and Accept which are both used for content negotiation. Content-Type indicates the format of the request body. This header is required for HTTP methods that create or modify resources (i.e., POST and PUT).The Accept header tells the server the response format desired by the client. If we want to receive resource representations in XML format, it would include an Accept header with a value of application/xml. If the server doesn't support the format of the body's request or the desired response, a 415 "Unsupported Media Type" error should be returned.
In addition to the HTTP headers, the expected format and content of the request body are defined. This information specifies the format in which resource representations will be submitted to the server (e.g., JSON or XML) as well as the information contained in that representation (e.g., field names and values). In order to provide flexibility to the client, REST services support multiple request formats such as JSON and XML. REST response also includes a status code that conveys the result of the requested operation. HTTP Basic Authentication is provided. If the username and password are accepted, then you will receive the response from the request. If they are not accepted, then the server is supposed to return an HTTP 401 Unauthorized response
