Hi,

I try to make a POST request with params and custom headers, but it not worked. When I try to make a GET request with my custom headers and URL params, it works.

I use a JsonObjectRequest and I try to add my POST params in a JSONObject or in the override method getParams but none of them work.

Can you help me? Thanks in advance.

I'm getting this error sometimes which causes my application to crash:

java.lang.NegativeArraySizeException: -450 at com.android.volley.toolbox.DiskBasedCache.streamToBytes(DiskBasedCache.java:322) at com.android.volley.toolbox.DiskBasedCache.get(DiskBasedCache.java:118) at com.android.volley.CacheDispatcher.run(CacheDispatcher.java:100)

The client the exception thrown as follows: java.lang.OutOfMemoryError at com.android.volley.toolbox.DiskBasedCache.streamToBytes(DiskBasedCache.java:322) at com.android.volley.toolbox.DiskBasedCache.readString(DiskBasedCache.java:540) at com.android.volley.toolbox.DiskBasedCache.readStringStringMap(DiskBasedCache.java:562) at com.android.volley.toolbox.DiskBasedCache$CacheHeader.readHeader(DiskBasedCache.java:403) at com.android.volley.toolbox.DiskBasedCache.initialize(DiskBasedCache.java:156) at com.android.volley.CacheDispatcher.run(CacheDispatcher.java:84)

Request some JSON format of data only. Please help to analyze what's the problem?

When I need to make a POST request, I set retry policy = 0, but when the HTTP request hits the timeout, Volley sends another request (and if the timeout is hit again, it will send another one).

Looks like someone else is seeing the same issue here: http://stackoverflow.com/questions/29034735/volley-makes-duplicate-post-call-at-timeout-mark

I'm experiencing it with 1.0.8, 1.0.10, 1.0.15. I didn't try other releases.

This is a major issue because POSTs are by definition not idempotent and I can't find a workaround using Volley with POSTs.

When the NetworkDispatcher is interrupted while doing a request, the exception is swallowed and the thread will wait forever on the blocking queue take() method.

I add volley library to my project using Android Studio(gradle version: 2.4), but the gradle complains that Failed to resolve: com.mcxiaoke.volley:library:1.0.18. However I change the volley to 1.0.17, it is OK.

code here.

@Override
public Map<String, String> getHeaders() throws AuthFailureError {
    Map<String,String> headers = new HashMap<String, String>();
    headers.put("Content-Type","application/x-www-form-urlencoded");
    return headers;
}

there a two Content-Type header in the HTTP request, one is from getHeader(), the other one is added by Volley.

Encountered in the course of a problem version 1.0.18

such as: new StringRequest(Request.Method.GET,url, new Response.Listener() { @Override public void onResponse(String response) {

        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {

        }
    });

I take request a tag . in fragment/activity stop ,call cancel.

but now has leak :

• GC ROOT thread com.android.volley.CacheDispatcher. (named 'Thread-16404')

I thinks reference to the fragment/activity will also be removed

Please refer to this link: https://stackoverflow.com/questions/26599636/should-i-worry-about-memory-leaks-and-using-weakreference-with-volley-in-android#=

If you do this request with volley https://maps.googleapis.com/maps/api/directions/json?sensor=true&origin=48.8256676,2.383315000000001&destination=50.6293797,3.0570117&alternatives=true

WIth a StringRequest or JsonRequest, a timeout occurs.

Here is my stacktrace can't reporduce it on my devices though :(

java.lang.NullPointerException at android.graphics.Bitmap.createBitmap(Bitmap.java:622) at android.graphics.Bitmap.createScaledBitmap(Bitmap.java:487) at com.android.volley.toolbox.ImageRequest.doParse(ImageRequest.java:169) at com.android.volley.toolbox.ImageRequest.parseNetworkResponse(ImageRequest.java:126) at com.android.volley.CacheDispatcher.run(CacheDispatcher.java:118)

Is there a workaround or this need to be fixed in library ?

logging like this :D/Volley: [54973] BasicNetwork.logSlowRequests: HTTP response for request=<[ ] https://us-centra...

How to disable it? I tried this code VolleyLog.DEBUG = false; at MyApplication.java but still showing on the logcat.

I am using Leakcanary for detecting memory leak in my app. but astonishingly leak canary reported memory leak in volley due to use of anonymous listener. I have asked this issue on StackOverflow below is the link:

anonymous-listener-of-volley-request-causing-memory-leak

void finish(Request<?> request) --> last line: mCacheQueue.addAll(waitingRequests);

how to understand this? why we transfer all requests in waitingRequests to cacheQueue this time instead of put them to cacheQueue originally created? u know, both action can add the request to NetworkQueue if can't get desired cache;?

hi,

I try the official volley library from Google. (version 1.0.0), still a lot of bugs not fixed.

Even this project consider deprecated, the code is still newer then official library with lot of bugs fixed, perhaps should remove the deprecated instead :)
