restapi casha store data but i want when i click on listview item all items from service they store in cacha

I apply cache but it works only one time when I click on first item it shows data after that when I click on another it shows same data how t fix it any guidelines
Here is my code
String URL = "http://facekart.azanic.com/Data_show_all_.php";
final ProgressDialog progressDialog = new ProgressDialog(getContext());
progressDialog.setMessage("Fetcing, please wait...");
progressDialog.show();
StringRequest request = new StringRequest(Request.Method.POST, URL, new Response.Listener<String>() {
#Override
public void onResponse(String s) {
progressDialog.dismiss();
try {
JSONObject jsonObject = new JSONObject(s);
JSONArray jsonArray = jsonObject.getJSONArray("result");//getting array
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject jsonObject1 = jsonArray.getJSONObject(i);

Handle response of multiple request from Volley Library

I am sending multiple request through for loop.
On response I get success or failure message, and I need to show this message in a AlertDialog.
My Problem is: when I am sending 10 request then I am getting 10 response hence 10 times dialogue is showing with response.
I want to show only one dialogue when all response will have come,and that dialogue should contain response according to their each and every request.
How can I do it.
code which I tried:
if (globalInstance.isNetworkAvailable(AddBookingList.this)) {
int si = checkedItems.size();
if (checkedItems.size() > 0) {
for (int i = 0; i < si; i++) {
int appid = checkedItems.get(i).getAppid();
int bookingId = checkedItems.get(i).getBookingid();
List<Contacts> con = db.getadvertisment(bookingId);
List<AddImages> img = db.getImagesbybookingId(bookingId);
String postXml = createxmlForPost(con, img);
sendDataToServer(postXml,appid, bookingId, si);
}
}
}
private void sendDataToServer(final String postXml, final int appid, final int bookingId, final int si) {
final ProgressDialog progressDialog = new ProgressDialog(this, R.style.AppCompatAlertDialogStyle);
progressDialog.setMessage("Please wait...");
progressDialog.setCancelable(false);
progressDialog.show();
try {
final RequestQueue queue = Volley.newRequestQueue(this);

obj.put("xmlData", postXml);
int socketTimeout = 30000;//30 seconds

new Response.Listener<String>() {
#Override
public void onResponse(String st) {
if (progressDialog != null || progressDialog.isShowing()) {
progressDialog.dismiss();
}
try {
JSONArray response = new JSONArray(st);
for (int i = 0; i < response.length(); i++) {
JSONObject jsonObject = response.getJSONObject(i);
int status = jsonObject.getInt("Status");
String msg = jsonObject.getString("Msg");
String serverbooking_id = jsonObject.getString("BookingId");
if (status == 1) {
checkedItems.clear();
if (response.length() > 1) {
String newserverbooking_id = response.getJSONObject(0).getString("BookingId") + "\n" + response.getJSONObject(1).getString("BookingId");
db.updateBookingDetailsbyAppId(newserverbooking_id, appid, status);
} else {
db.updateBookingDetailsbyAppId(serverbooking_id, appid, status);
}
showDatainList();
globalInstance.showSuceessMessage(true, "Success!!! Your BookingID is: " + serverbooking_id, AddBookingList.this);
try {
List<Contacts> contacts = db.getAllBookingDetails();
for (int h = 0; h < contacts.size(); h++) {

As i understand your problem is calling globalInstance.showSuceessMessage() or globalInstance.showFailureMessage every time you get the response.
what i think might work is:
Instead of these two methods, define an Arraylist<String> and based on the
success or failure of the response add messages to it like "Success!!! Your BookingID is: " + serverbooking_id and "Booking Failed." + msg.
Define a method like showMessages() which has a dialogue containing the messages u added to arraylist before. then call it after where you called thesendDataToServer method which is in the if (checkedItems.size() > 0) block.

My app crashes when there is no value in my JSON

I'm posting "id" value (which i pass to this activity via getintent)
Uid = getIntent().getStringExtra("id");
to server and retrieving the corresponding jsonobjects.
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("id", Uid);
return params;
}
When my jsonarray is empty, my app crashes. I want to toast"Error" when jsonarray is empty. How can I fix this?
Here is my code:
public class kill extends FragmentActivity {
GridView grid1;
CustomGrid_Album adapter;
private ProgressDialog pDialog;
String Uid,Disp;
public String category;
public String selected;
public static String imagename;
Button Alb_sel;
ArrayList<Item_album> gridArray = new ArrayList<Item_album>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.album_display);
grid1 = (GridView) findViewById(R.id.gridView2);
Uid = getIntent().getStringExtra("id");
Disp = getIntent().getStringExtra("disp");
Alb_sel=(Button)findViewById(R.id.album_to_select);
pDialog = new ProgressDialog(kill.this);
pDialog.setMessage("Loading...");
pDialog.show();
//fetching JSONArray
final RequestQueue queue = Volley.newRequestQueue(getApplicationContext());
StringRequest stringRequest = new StringRequest(com.android.volley.Request.Method.POST, AppConfig.URL_Gallery4,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Datas.imageIds = new String[response.length()];
JSONArray arr = null;
try {
arr = new JSONArray(response);
} catch (JSONException e1) {
e1.printStackTrace();
}
int i=0;
for (i = 0; i < arr.length(); i++) {
try {
JSONObject obj = arr.getJSONObject(i);
category = obj.getString("category_name");
selected = obj.getString("album_id");
imagename = obj.getString("org_image_name");
Datas.imageIds[i] = AppConfig.URL_IMAGE_temp+obj.getString("album_image").substring(3);
gridArray.add(new Item_album(Datas.imageIds[i]));
} catch (JSONException e) {
e.printStackTrace();
}
}
final int xl = i;
adapter = new CustomGrid_Album(kill.this,xl,gridArray);
adapter.notifyDataSetChanged();
grid1.setAdapter(adapter);
pDialog.dismiss();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getApplicationContext(), "No images in this gallery", Toast.LENGTH_SHORT).show();
error.printStackTrace();
}
})
{
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("id", Uid);
return params;
}
};
queue.add(stringRequest);
}
}

apply the check in onResponse
if(response.length()==0){
// error message
}else{
// your rest of the code
}

This looks problematic.
Datas.imageIds = new String[response.length()];
You don't want an array with the size of the string. You want an array of the size of the JSONArray within the response.
public void onResponse(String response) {
JSONArray arr = null;
try {
arr = new JSONArray(response);
Datas.imageIds = new String[arr.length()];
} catch (JSONException e1) {
e1.printStackTrace();
}
However, your code is going to continue on if an exception is thrown there, then you'll end up with a NullPointerException, so you should move the for-loop into the try-catch as well.
Realistically, though, you should just use a JSONArrayRequest if you're going to be expecting a JSONArray.
i want to toast"Error" when jsonarray is empty
Simple enough.
arr = new JSONArray(response);
if (arr.length() == 0) {
// TODO: Toast
}

I would simply add two checks to your onResponse method:
...
public void onResponse(String response) {
// Check if the response itself is an empty string or null
if(TextUtils.isEmpty(response)) {
// Show your user feedback
return;
}
Datas.imageIds = new String[response.length()];
JSONArray arr = null;
try {
arr = new JSONArray(response);
// Check if your JSON has no elements in it
if(arr.length == 0) {
// Show your user feedback
return;
}
} catch (JSONException e1) {
e1.printStackTrace();
}
...

You have declared JSONArray arr = null;
After that you assign the server's JSON to that JSONArray.
Add a line after getting that
if(arr==null)
{
//toast
}
else
{
//whatever you want to do with JSON
}

StringRequest stringRequest = new StringRequest(com.android.volley.Request.Method.POST, AppConfig.URL_Gallery4,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
if(response.length()==0){
Toast.makeText(getActivity(),"no data found",Toast.LENGTH_SHORT).show();
}
else{
Datas.imageIds = new String[response.length()];
JSONArray arr = null;
try {
arr = new JSONArray(response);
} catch (JSONException e1) {
e1.printStackTrace();
}
if(arr.length()>0){
int i=0;
for (i = 0; i < arr.length(); i++) {
try {
JSONObject obj = arr.getJSONObject(i);
category = obj.getString("category_name");
selected = obj.getString("album_id");
imagename = obj.getString("org_image_name");
Datas.imageIds[i] = AppConfig.URL_IMAGE_temp+obj.getString("album_image").substring(3);
gridArray.add(new Item_album(Datas.imageIds[i]));
} catch (JSONException e) {
e.printStackTrace();
}
}
final int xl = i;
adapter = new CustomGrid_Album(kill.this,xl,gridArray);
adapter.notifyDataSetChanged();
grid1.setAdapter(adapter);
}else{
Toast.makeText(getActivity(),"no data found",Toast.LENGTH_SHORT).show();
}
}
pDialog.dismiss();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getApplicationContext(), "No images in this gallery", Toast.LENGTH_SHORT).show();
error.printStackTrace();
}
})
{
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("id", Uid);
return params;
}
};

Use the below code to check whether response is null or not and in object check whether it is having key or data with key is not null
if(response!=null){
try {
Datas.imageIds = new String[response.length()];
JSONArray arr = new JSONArray(response);
for (int i = 0; i < arr.length(); i++) {
try {
JSONObject obj = arr.getJSONObject(i);
if(obj!=null){
if(obj.has("category_name") && !obj.isNull("category_name"){
category = obj.getString("category_name");
}
if(obj.has("album_id") && !obj.isNull("album_id"){
selected = obj.getString("album_id");
}
if(obj.has("org_image_name") && !obj.isNull("org_image_name"){
imagename = obj.getString("org_image_name");
}
if(obj.has("album_image") && !obj.isNull("album_image"){
Datas.imageIds[i] = AppConfig.URL_IMAGE_temp+obj.getString("album_image").substring(3);
gridArray.add(new Item_album(Datas.imageIds[i]));
}
}
} catch (JSONException e) {
e.printStackTrace();
}
}
final int xl = i;
adapter = new CustomGrid_Album(kill.this,xl,gridArray);
adapter.notifyDataSetChanged();
grid1.setAdapter(adapter);
pDialog.dismiss();
} catch (JSONException e1) {
e1.printStackTrace();
}
}

You are using StringRequest, instead of that use JsonArrayRequest to make request as below, so you will get response in onResponse methode when there is a valid JSONArray in response, and if there is no data then you will get response in onError method
JsonArrayRequest rReq = new JsonArrayRequest(Request.Method.GET,"url", new JSONObject(), new Response.Listener() {
#Override
public void onResponse(JSONArray response) {
Log.e(TAG, "onResponse: "+response.toString() );
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e(TAG, "onErrorResponse: "+error.getMessage() );
}
})

Volley Cache not get updated

Hi I am using volley jar in my android app to cache the json data for the offline mode.It works perfectly.Here is my code
Cache cache1 = AppController.getInstance().getRequestQueue().getCache();
Entry entry1 = cache1.get(URL);
if (entry1 != null) {
// fetch the data from cache
try {
data2 = new String(entry1.data, "UTF-8");
try {
parseJsonFeed(new JSONObject(data2));
} catch (JSONException e) {
e.printStackTrace();
}
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
} else {
AppController.getInstance().getRequestQueue().getCache().remove(URL);
// making fresh volley request and getting json
JsonObjectRequest jsonReq1 = new JsonObjectRequest(Method.GET,
URL, null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
VolleyLog.d(TAG, "Response: " + response.toString());
if (response != null) {
parseJsonFeed(response);
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error:" + error.getMessage());
}
});
// Adding request to volley request queue
AppController.getInstance().addToRequestQueue(jsonReq1);
}
private void parseJsonFeed(JSONObject response) {
try {
feedArray = response.getJSONArray("events");
for (int i = 0; i < feedArray.length(); i++) {
feedObj = (JSONObject) feedArray.get(i);
event_id.add(feedObj.getInt("event_id"));
event_desc.add(feedObj.getString("event_title"));
event_date.add(feedObj.getString("event_date"));
event_place.add(feedObj.getString("event_place"));
event_time.add(feedObj.getString("event_time"));
}
listView.setAdapter(new dataListAdapter(event_date,event_desc,event_place,event_time));
//Log.i("event1111", event.toString());
// Log.i("event2222", event2.toString());
Toast.makeText(getActivity(), "dataa"+event_id, 5000).show();
} catch (JSONException e) {
e.printStackTrace();
}
}
my problem is that I got data.But When I updated json data,the cache data will not update.So how can I change cache data based on json data.Please help me thanks in advance :)

Set the cache header response of your server correctly, I think you need to change the max-age of the header or any custom configuration because Volley looks at the header then stores the response in the cache, here is how it dose:
headerValue = headers.get("Cache-Control");
if (headerValue != null) {
hasCacheControl = true;
String[] tokens = headerValue.split(",");
for (int i = 0; i < tokens.length; i++) {
String token = tokens[i].trim();
if (token.equals("no-cache") || token.equals("no-store")) {
return null;
} else if (token.startsWith("max-age=")) {
try {
maxAge = Long.parseLong(token.substring(8));
} catch (Exception e) {
}
} else if (token.equals("must-revalidate") || token.equals("proxy-revalidate")) {
maxAge = 0;
}
}
}
headerValue = headers.get("Expires");
if (headerValue != null) {
serverExpires = parseDateAsEpoch(headerValue);
}
serverEtag = headers.get("ETag");
// Cache-Control takes precedence over an Expires header, even if both exist and Expires
// is more restrictive.
if (hasCacheControl) {
softExpire = now + maxAge * 1000;
} else if (serverDate > 0 && serverExpires >= serverDate) {
// Default semantic for Expire header in HTTP specification is softExpire.
softExpire = now + (serverExpires - serverDate);
}
Cache.Entry entry = new Cache.Entry();
entry.data = response.data;
entry.etag = serverEtag;
entry.softTtl = softExpire;
entry.ttl = entry.softTtl;
entry.serverDate = serverDate;
entry.responseHeaders = headers;

Stop creating fragmnet view until i have parsed all data from Json.

I receive a null pointer exeception when trying to populate the interface beacuse I have no data in my instance object.
I am using a login button and call a service, i receive a json and after I parse it i have a status handler...login ok... Here I want to start an asynk task to get some photo data
public void StatusHandlerLogin(String status, Activity currentActivity) {
if (status.equals("0")) {
new GetPhotoDataTask(currentActivity).execute();
Intent intent = new Intent(currentActivity,
NavigationActivity.class);
currentActivity.startActivity(intent);
}
//}
The asynk task is like this

on do in background i have a method that call other service
get PhotoData with userId as param

List<PhotoData> photoDataList = new ArrayList<PhotoData>();
if (response != null) {

}
return photoDataList;
}
and if response is not null i parse it
public static List<PhotoData> parseJsonArrayForFotoData(JsonArray jsonArray) {

PhotoData photoData = new PhotoData(photoID.toString(),
photoUrl.toString(), thumbURL.toString(), null, tagsList);
photoDataList.add(photoData);
}
return photoDataList;
}
ok in GetPhotoDataTaskFb do in background i set the instance of the photos object
AppManager.getInstance().setphotoUrls(photoUrls);
and in fragmnet
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
rootView = inflater.inflate(R.layout.ac_image_pager, container,
false);
// Dummy code
if (counter == 0) {
for (int i = 0; i <= 20; i++) {
try {
Thread.sleep(100);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
counter++;
String[] imageUrls = AppManager.getInstance().getphotoUrls();
//here is where i get the null.. i tried some dummy code to delay and receive data but it is not working
How can I manage to stop create view until all data is parsed?
