我想提出的是上传图片到服务器,并更新其数据库中的Android服务器在执行它的应用程序,它显示了一个错误
Connection to http://localhost refused
和许多更多的错误,我研究这个问题,并发现,而不是提供的URL连接
http://localhost/... provide the link as http://10.0.2.2/...
我这样做,但问题是相同的多个错误是在这里:

文件上传的代码是:
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;
}
}
在调试代码最多时达:
httpPost.setEntity(entity);
它表明这条线即在此声明后的异常:
HttpResponse response = httpClient.execute(httpPost, localContext);
可以在任何一个可以帮助我在这?
