最近我正在開發Android應用程序 我想要做的是使用來自.NET WCF的web服務 到我的應用程序連接到Android上使用JSON WCF web服務
這是我的客戶端代碼

import java.io.InputStreamReader;
import org.apache.http.HttpEntity;<br>
import org.apache.http.HttpResponse;<br>
import org.apache.http.client.methods.HttpGet;<br>

import android.widget.TextView;<br>
public class MyPamIndex extends Activity {
private final static String SERVICE_URI = "http://172.30.2.95:9000/JSON/MyPam.svc";
private TextView NabVals;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_pam_index);
NabVals = (TextView)findViewById(R.id.textView2);
}
public void OnRefreshClick(View button)
{
try {
// Send GET request to <service>/GetVehicle/<plate>
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet request = new HttpGet(SERVICE_URI + "/ProductID/" + "1");
request.setHeader("Accept", "application/json");
request.setHeader("Content-type", "application/json");
HttpResponse response = httpClient.execute(request);
HttpEntity responseEntity = response.getEntity();
// Read response data into buffer
char[] buffer = new char[(int)responseEntity.getContentLength()];
InputStream stream = responseEntity.getContent();
InputStreamReader reader = new InputStreamReader(stream);
reader.read(buffer);
stream.close();
JSONObject vehicle = new JSONObject(new String(buffer));
NabVals.setText(vehicle.getString("NabValue"));
// Populate text fields
} catch (Exception e) {
e.printStackTrace();
}
}
當我運行的應用程序它有一個錯誤 在 HttpResponse響應= httpClient.execute(請求); 我有搜索整個論壇,但沒有發現任何 我已經加我的Android清單文件,但仍然沒有工作 請幫我
這是我的清單文件
