Jersey客户端与协议缓存的Android [英] Jersey client in android with protocol buffer
本文介绍了Jersey客户端与协议缓存的Android的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想使用的协议缓存在Android中创建一个Jersey客户端。
我使用下列库：
新泽西州的客户1.8.jar
球衣的核心 - 1.8.jar
protobuf的-java的2.4.0a.jar
I would like to create a Jersey client in Android using protocol buffer. I am using the following libraries: jersey-client-1.8.jar jersey-core-1.8.jar protobuf-java-2.4.0a.jar
在code我已经写：
import com.sun.jersey.api.client.ClientRequest;
import com.sun.jersey.api.client.ClientResponse;
import com.sun.jersey.api.client.WebResource;
import com.sun.jersey.api.client.WebResource.Builder;
import com.sun.jersey.api.client.filter.ClientFilter;
import com.sun.jersey.api.client.filter.HTTPBasicAuthFilter;
BaseRestClient client = BaseRestClient.create("", "");
HTTPBasicAuthFilter authenticationFilter =
new HTTPBasicAuthFilter(username, password);
client.addFilter(authenticationFilter);
..........
..........
WebResource webResourceGetMea = client.resource(url);
webResourceGetMea = webResourceGetMea.path("/accounts").path("/login");
ClientResponse responseGetMea = webResourceGetMea.type("application/x-protobuf").get(ClientResponse.class);
以上code作为主要的Java（）的应用程序成功运行，但是当我运行它在Android上responseGetMea（）对象为空（code的最后一行）。
The above code is running successfully as Java main() application but when I am running it on Android the responseGetMea() object is null (last line of code).
我使用的是应用程序/ x-protobuf的，因为在这样的方式它是在服务器端定义。
我在我的Android应用程序添加INTERNET权限。
我也是从Android浏览器检查的网址，当我点击它，它提示我输入用户名和密码（预期的行为）。
I am using the "application/x-protobuf" because in such way it was defined on server side. I have added the INTERNET permission in my Android application. I also checked the URL from Android browser and when I click it, it prompts me to input the user name and the password(the expected behaviour).
我真的AP preciate任何帮助。
I really appreciate any help.

这是另外...当试图与它有一些错误抱怨previous链接的版本，Buscador才能发布。 Buscador的新版本张贴工作如下，
