问题 I have a recurring problem in my Android application. Basically I am using PHP and a MYSQL database to register and login users into my app. Registration works fine. I am able to connect to the database and insert the new user into the table without any problems. The issue I am facing is when logging into the app. Whenever I call the login url, I am getting the following error: BasicNetwork.performRequest: Unexpected response code 500 for URL.

问题 I want app to show dates in listview. My app has TabLayout which imitates this and Listviews which imitate this.So, tabs have listview. After showing all json dates in listview, they load json dates again. It happens when I swipe each tabs like tab1→tab2→tab3→tab1→tab3... . This is may code. If anyone knows what is wrong, please teach me. public class AppController extends Application { public static final String TAG = AppController.class.getSimpleName(); private RequestQueue mRequestQueue;

问题 I read the documentation about making an network request activity independent by making a singleton class and passing the application context to it. I implemented it similarly, however I still find that on rotation the app waits for the call again to complete before displaying any data. So what am I doing wrong and how to set it up properly so that the call lasts the lifetime of the application so that it doesn't call every time on orientation change as per the documentation. I know it can be

问题 I want to upload files(images,documents etc) from my android application to my server.I'm using Volley library for network calls in my application. I'm using the following code to upload files but it is not performing any operation.(showing volley timeout error finally) public class MultipartRequest extends Request<String> { private MultipartEntity entity = new MultipartEntity(); private static final String FILE_PART_NAME = "file"; private final Response.Listener<String> mListener; private

问题 I am using Android Volley for network calls. Generally I use JSONRequest to receive the json data and then convert them into object using GSON. new Response.Listener<JSONObject>() { @Override public void onResponse(JSONObject response) { ///Convert response.toString() to POJO using GSON } }; If I use plain string request and then convert string to objects using GSON, will that be more faster than JSONRequest? new Response.Listener<String>() { @Override public void onResponse(String response)

问题 i want to fetch some data from a URL and the server is very slow... So whenever i use volley to get the data, I get TimeOurError , Is there anyway i can handle for how long volley should try to get the data as the server is slow...It takes little time and i also want to run this request constantly to check data, I plan to use Timer for it...Is it okay to use Timer for continuously checking data? Here is my volley request for now...It works for other URL's public void checkData() {

问题 I am fetching json data through Volley. The problem I am having is that Volley's onResponse is never called, and hence the data are not parsed and displayed. Sample JSON data { "title": "This is a sample text title title", "cat": { "origin" : "United states", "target" : "Asia", }, "content": "Lorem ipsum ipsum trxt hag jlak jshss jsyts pjqgq uuqtyq usiuqjo uwywh", } NewsActivity public class NewsDetails extends AppCompatActivity { private final String TAG = "NewsDetails"; private

问题 hello. I want to make a post request using gson.
