I am making an application that uploads images to server and updates its database to server in android while executing it, it shows an error

Connection to http://localhost refused 

和更多的错误,我研究了这个问题,而不是提供URL连接

我这样做,但问题是一样的

代码

public int uploadFile(ArrayList<String> sourceFileUri, String info, String latitude, String longitude, String id) throws IOException {
        try {
            HttpClient httpClient = new DefaultHttpClient();
            HttpContext localContext = new BasicHttpContext();
            HttpPost httpPost = new HttpPost("http://10.0.2.2/deliverysystem/order/add");

            MultipartEntity entity = new MultipartEntity(
                    HttpMultipartMode.BROWSER_COMPATIBLE);

            entity.addPart("returnformat", new StringBody("json"));
            System.out.println(sourceFileUri.size());
            for(int i=0;i<sourceFileUri.size();i++){
                String sourceFile = sourceFileUri.get(i);
                entity.addPart("uploaded_file"+(i+1), new FileBody(new File(sourceFile)));
            }

            entity.addPart("fld_delivery_id", new StringBody(id));
            entity.addPart("fld_delivery_location", new StringBody(info));
            entity.addPart("fld_latitude", new StringBody(latitude));
            entity.addPart("fld_longitude", new StringBody(longitude));
            httpPost.setEntity(entity);
            HttpResponse response = httpClient.execute(httpPost, localContext);
            BufferedReader reader = new BufferedReader(
                    new InputStreamReader(
                            response.getEntity().getContent(), "UTF-8"));

            String sResponse = reader.readLine();
            return 1;
        } catch (Exception e) {
            if (dialog.isShowing())
                dialog.dismiss();

            Log.e(e.getClass().getName(), e.getMessage(), e);
            return 1;
        }

       }

httpPost.setEntity(entity);

并且在此行后面显示异常,即在此语句中:

and it shows exception after this line ie on this statement:

HttpResponse response = httpClient.execute(httpPost, localContext);

任何人都可以帮助我吗?

Could any one help me on this?

推荐答案

如果你使用模拟器运行你的应用程序的本地服务器。将本地 ip 标记为 10.0.2.2 ,并且必须为您的应用授予互联网权限:

if you are using emulator to run your app for local server. mention the local ipas 10.0.2.2 and have to give Internet permission into your app :

<uses-permission  android:name="android.permission.INTERNET" />
