Json parsing Using Volley does not get cahced - json

Question

I Parse json using volley framework, which every time gets response from the server, does not check the cache, It has taken a whole day, Here is my code. Any of you have used volley for parsing json are expected to help
Cache cache = AppController.getInstance().getRequestQueue().getCache();
Entry entry = cache.get(diag_url);
if(entry != null){
try {
String data = new String(entry.data, "UTF-8");
// handle data, like converting it to xml, json, bitmap etc.,
// Parsing json
JSONArray jsonArray = new JSONArray(data);
for (int i = 0; i < jsonArray.length(); i++) {
try {
DiagRegPojo test = new DiagRegPojo();
JSONObject obj = jsonArray.getJSONObject(i);
String testName = obj.getString("content");
Log.d("Response From Cache", testName);
test.setTitle(testName);
// adding movie to movies array
testList.add(test);
} catch (JSONException e) {
e.printStackTrace();
}
}
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (JSONException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}else{
// Creating volley request obj
JsonArrayRequest testReq = new JsonArrayRequest(diag_url,
new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
Log.d(TAG, response.toString());
hidePDialog();
// Parsing json
for (int i = 0; i < response.length(); i++) {
try {
JSONObject obj = response.getJSONObject(i);
DiagRegPojo test = new DiagRegPojo();
test.setTitle(obj.getString("content"));
Log.d("Response From Server", obj.getString("content"));
// adding movie to movies array
testList.add(test);
} catch (JSONException e) {
e.printStackTrace();
}
}
// notifying list adapter about data changes
// so that it renders the list view with updated data
mAdapter.notifyDataSetChanged();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
hidePDialog();
}
})
{
//**
// Passing some request headers
//*
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Cookie", MainActivity.sharedpreferences.getString(savedCookie, ""));
headers.put("Set-Cookie", MainActivity.sharedpreferences.getString(savedCookie, ""));
headers.put("Content-Type", "application/x-www-form-urlencoded");
//headers.put("Content-Type","application/json");
headers.put("Accept", "application/x-www-form-urlencoded");
return headers;
}
};
// Adding request to request queue
AppController.getInstance().addToRequestQueue(testReq);
}
}

To cache images, I have used this. sure it can be of some help to you.
public ImageLoader getImageLoader() {
getRequestQueue();
if (mImageLoader == null) {
mImageLoader = new ImageLoader(this.mRequestQueue,
new LruBitmapCache());
}
return this.mImageLoader;
}
.
public class LruBitmapCache extends LruCache<String, Bitmap> implements
ImageCache {
public static int getDefaultLruCacheSize() {
final int maxMemory = (int) (Runtime.getRuntime().maxMemory() / 1024);
final int cacheSize = maxMemory / 8;
return cacheSize;
}
public LruBitmapCache() {
this(getDefaultLruCacheSize());
}
public LruBitmapCache(int sizeInKiloBytes) {
super(sizeInKiloBytes);
}
#Override
protected int sizeOf(String key, Bitmap value) {
return value.getRowBytes() * value.getHeight() / 1024;
}
#Override
public Bitmap getBitmap(String url) {
return get(url);
}
#Override
public void putBitmap(String url, Bitmap bitmap) {
put(url, bitmap);
}
}
