If you use any of the default Request classes implemented in volley(e.g. StringRequest, JsonRequest, etc.), then call setShouldCache(false) right before adding the request object to the volley RequestQueue: request.setShouldCache(false); myQueue.add(request); If you have your own implementation of the Request class, then you can call setShouldCache(false) in the constructor of your class. This solution disables caching … Read more
As pointed out by others as well, Volley is officially available on Github: Add this line to your gradle dependencies for volley: compile ‘com.android.volley:volley:1.0.0’ To install volley from source read below: I like to keep the official volley repository in my app. That way I get it from the official source and can get updates … Read more
For your comment I think that async is provided by Volley automatically. So i need to know how to get JSON data into the first snippet IMO, instead of your first snippet, you can try the following way (of course, you can replace JSONArray request by JSONObject request): VolleyResponseListener listener = new VolleyResponseListener() { @Override … Read more
Google Volley provides 2 ways to clear an item from the Cache: AppController.getInstance().getRequestQueue().getCache().remove(key); and AppController.getInstance().getRequestQueue().getCache().invalidate(key, fullExpire); Remove means you are removing the actual cached data. Invalidate means you are just marking the data as invalid. So volley will check with the server whether the data is still valid. The full expire determines whether to use … Read more
No need to use connection.setChunkedStreamingMode(0); to avoid volley sending data twice bug. you need to set retry policy for current request : JsonObjectRequest jsonObjReq = new JsonObjectRequest(…); jsonObjReq.setRetryPolicy(new DefaultRetryPolicy( 0, DefaultRetryPolicy.DEFAULT_MAX_RETRIES, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
I’ve implemented something similar to this, and it’s relatively simple. Your log message is printing out what looks like gibberish, because response.data is really a byte array – not a String. Also, a VolleyError is really just an extended Exception, so Exception.getMessage() likely wouldn’t return what you are looking for unless you override the parsing … Read more
Use HashMap<String ,String> params=new HashMap<String, String>(7); for(int i=1;i<=7;i++) { params.put(“params_”+i, arr[i]); } in CustomJobjectRequest class because currently you are using String type as value in Map in CustomJobjectRequest class but sending String[] type when create object of CustomJobjectRequest class. Edit: To send all values in single parameter to server use JSONObject.Create a json object using … Read more
You can use the following working sample code. I have tested. Hope this helps! try { jsonBody = new JSONObject(); jsonBody.put(“Title”, “VolleyApp Android Demo”); jsonBody.put(“Author”, “BNK”); jsonBody.put(“Date”, “2015/08/26”); requestBody = jsonBody.toString(); StringRequest stringRequest = new StringRequest(1, url, new Response.Listener<String>() { @Override public void onResponse(String response) { textView.setText(response); } }, new Response.ErrorListener() { @Override public void … Read more
Or, how can I ensure error.networkResponse is non-null in onErrorResponse? My first thought would be to check if the object is null. @Override public void onErrorResponse(VolleyError error) { NetworkResponse networkResponse = error.networkResponse; if (networkResponse != null && networkResponse.statusCode == HttpStatus.SC_UNAUTHORIZED) { // HTTP Status Code: 401 Unauthorized } } Alternatively, you could also try grabbing … Read more
In the streamToBytes(), first it will new bytes by the cache file length, does your cache file was too large than application maximum heap size ? private static byte[] streamToBytes(InputStream in, int length) throws IOException { byte[] bytes = new byte[length]; … } public synchronized Entry get(String key) { CacheHeader entry = mEntries.get(key); File file … Read more
