I am facing a problem where my POST request parameters are not going to server after 1st time. I know Volley is using cache mechanism for responses, but in my case my request parameter values can be changed at runtime as i am using pagination in Recyclerview.
So my questions is how can i send Post request parameter every time and wont loose cache mechanism of volley.
I have tried using below ones and get my things done (calling getParams() every-time).. but it loses caches response and i don't want that.
requestQueue.getCache().clear();
stringRequest.setShouldCache(false);
Also have Searched Google and below links but cant find any proper solution. below are the SO links
- Volley not calling getParams() for second time
- Volley not calling getParams()
- Android volley does not calling getParams in POST request
- Volley not calling getParams() for standard POST request
Below is my code:
StringRequest stringRequest = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() { @Override public void onResponse(String response) { Log.e("RES", response); GsonBuilder gsonBuilder = new GsonBuilder(); gsonBuilder.setDateFormat("M/d/yy hh:mm a"); //Format of our JSON dates Gson gson = gsonBuilder.create(); NewsFeedPOJO resultObj = (NewsFeedPOJO) gson.fromJson(response, (Class) NewsFeedPOJO.class); inCurrPage = Integer.parseInt(resultObj.getPagination().getCurrent_page()); inTotalPage = Integer.parseInt(resultObj.getPagination().getTotal_pages()); inCurrPage++; arrayList.addAll(resultObj.getNewsFeedList()); if (isFtym) { isFtym = false; layoutManager = new LinearLayoutManager(MainActivity.this); rcNewsFeed.setLayoutManager(layoutManager); adapter = new NewsFeedAdapter(MainActivity.this, arrayList); rcNewsFeed.setAdapter(adapter); } else { adapter.notifyItemInserted(arrayList.size()); adapter.notifyDataSetChanged(); } } }, new Response.ErrorListener() { @Override public void onErrorResponse(VolleyError error) { } }) { @Override protected Map<String, String> getParams() throws AuthFailureError { Map<String, String> map = new HashMap<>(); map.put("user_id", "188"); if (inCurrPage == 0) map.put("page", "1"); else { map.put("page", "" + inCurrPage); } Log.e("RES", inCurrPage + " PARA"); return map; } }; //RequestQueue requestQueue = Volley.newRequestQueue(MainActivity.this); //requestQueue.add(stringRequest); //requestQueue.getCache().clear(); //AppController.getInstance().addToRequestQueue(stringRequest); // stringRequest.setShouldCache(false); VolleySingleton.getInstance(this).addToRequestQueue(stringRequest); using below Volley Dependency.
compile 'com.android.volley:volley:1.1.0' If need more information please do let me know. Thanks in advance. Your efforts will be appreciated.

Did you checked your Volley Singleton is correct or not ?
import android.content.Context; import android.graphics.Bitmap; import android.util.LruCache; import com.android.volley.Request; import com.android.volley.RequestQueue; import com.android.volley.toolbox.ImageLoader; import com.android.volley.toolbox.Volley; public class VolleySingleton { private static AppSingleton mAppSingletonInstance; private RequestQueue mRequestQueue; private ImageLoader mImageLoader; private static Context mContext; private AppSingleton(Context context) { mContext = context; mRequestQueue = getRequestQueue(); mImageLoader = new ImageLoader(mRequestQueue, new ImageLoader.ImageCache() { private final LruCache<String, Bitmap> cache = new LruCache<String, Bitmap>(20); @Override public Bitmap getBitmap(String url) { return cache.get(url); } @Override public void putBitmap(String url, Bitmap bitmap) { cache.put(url, bitmap); } }); } public static synchronized AppSingleton getInstance(Context context) { if (mAppSingletonInstance == null) { mAppSingletonInstance = new AppSingleton(context); } return mAppSingletonInstance; } public RequestQueue getRequestQueue() { if (mRequestQueue == null) { // getApplicationContext() is key, it keeps you from leaking the // Activity or BroadcastReceiver if someone passes one in. mRequestQueue = Volley.newRequestQueue(mContext.getApplicationContext()); } return mRequestQueue; } public <T> void addToRequestQueue(Request<T> req,String tag) { req.setTag(tag); getRequestQueue().add(req); } public ImageLoader getImageLoader() { return mImageLoader; } public void cancelPendingRequests(Object tag) { if (mRequestQueue != null) { mRequestQueue.cancelAll(tag); } } } Or maybe there is other in your code.
