Volley – Sending a POST request using JSONArrayRequest

Android set up Volley to use from cache

Please note that if the web service supports caching output, you don’t have to use CacheRequest below, because Volley will automatically cache.

Hope this help! JsonObjectRequest jsonObjectRequest = … Read more

Android Volley – BasicNetwork.performRequest: Unexpected response code 400

One way of doing this without changing Volley‘s source code is to check for the response data in the VolleyError and parse it your self.

Change Volley timeout duration

See Request.setRetryPolicy() and the constructor for DefaultRetryPolicy, e.g. JsonObjectRequest myRequest = new JsonObjectRequest(Method.GET, url, null, new Response.Listener<JSONObject>() { @Override public void onResponse(JSONObject response) { Log.d(TAG, response.toString()); } }, new Response.ErrorListener() { @Override public void onErrorResponse(VolleyError error) { Log.d(TAG, “Error: ” + error.getMessage()); } }); myRequest.setRetryPolicy(new DefaultRetryPolicy( MY_SOCKET_TIMEOUT_MS, DefaultRetryPolicy.DEFAULT_MAX_RETRIES, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));

Volley – POST/GET parameters

For the GET parameters there are two alternatives: First: As suggested in a comment bellow the question you can just use String and replace the parameters placeholders with their values like: String uri = String.format(“http://somesite.com/some_endpoint.php?param1=%1$s&param2=%2$s”, num1, num2); StringRequest myReq = new StringRequest(Method.GET, uri, createMyReqSuccessListener(), createMyReqErrorListener()); queue.add(myReq); where num1 and num2 are String variables that contain … Read more
