问题 I am using the volley networking library for android. I'am looking for a way to get notified when a bunch of requests are finished, rather than checking all the response listeners individualy (which i also do). Is there an easy way to get a callback from the queue when all tasks are done? 回答1: Keep the requests count in a member variable and decrement everytime a request finishes, and when the counter goes to 0, you're done! I'm not aware of a callback exposed that tracks all the requests and

问题 Volley library doesn't return whole response data. It only return the part of the response data. I am calling drupal services. Below is my code for it. public void BoardRoomRequest() { pdialog = new ProgressDialog(BoardRoom.this); pdialog.setTitle("Please wait...."); String url = Global_Application.url + "views/boardroom"; Log.d("url========", url); Map<String, String> params = new HashMap<String, String>(); StringRequest req = new StringRequest(Request.Method.GET, getApplicationContext(),

问题 In my app for Android I'm using Volley for loading images in custom listview. when i refresh(delete all items and load tiems) listview many times, my app is killed with this message how can i fix it? 04-26 13:08:01.038: E/dalvikvm-heap(18040): Out of memory on a 1684947261-byte allocation. 04-26 13:08:01.038: I/dalvikvm(18040): "Thread-11094" prio=5 tid=299 RUNNABLE 04-26 13:08:01.038: I/dalvikvm(18040): | group="main" sCount=0 dsCount=0 obj=0x439ea8e8 self=0x7fb55250 04-26 13:08:01.038: I

问题 After reading this article, I started thinking about memory leaks with Volley. Usually, the listeners implemented with Volley have either an implicit or explicit reference to the outer class (the activity). for example: JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.GET, url, null, new Response.Listener<JSONObject>() { @Override public void onResponse(JSONObject response) { updateLayout(); } } in this case there is an implicit reference... or I may want to create a custom

问题 I almost always use a Service when I download data from a web service. I store the result in a database and displays the result in my view using a cursor loader. But after Google released the network library Volley I have become a bit confused. The volley library uses async tasks instead of a Service and it doesn't use cursors. I thought that I was supposed to avoid async task and store my data in a database so that I could handle orientation changes properly - without loosing data and having

问题 I am currently making a get request using volley and in onResponse i am trying to parse the jsonObject using gson to my model.

问题 Scenario - upload binary data in the body of a post, handle a response body containing JSON. How to do the following using Volley? curl -X POST -H "X-Application-Id: 3KxPB" -H "X-REST-API-Key: jkuI9" -H "Content-Type: audio/3gp" --data-binary '@test.3gp' https://host/1/files/audio IMO - there is a gap in Volley handling binary POST body types that apache httpclient handles in subclasses of abstracthttpentity. If buffered binary data generated on the phone by camera, microphone, or other

问题 I try to use Volley library and upload image to server. This library should do this process in standalone mode, but have got following error message: java.net.SocketException: sendto failed: ECONNRESET (Connection reset by peer) Is it maybe a server side misconfiguration? I try to upload a jpeg image with this code: private void uploadImage(){ final ProgressDialog loading = ProgressDialog.show(this,"Uploading...","Please wait...",false,false); StringRequest stringRequest = new StringRequest

问题 I'm currently developing an instant message application based on FCM (Firebase Cloud Message). My problem lies in the follow scenario: User is connected to an intermitent network - i.e. a wi-fi that, although holds the connection with the device, might lose internet connection from time to time with the internet provider; User attempts to send a message (a POST request using volley) when the device is connected to the wi-fi but with no internet connection; What is the best way to tackle this
