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";

#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);
Itemssetget it = new Itemssetget();
it.setName(jsonObject1.getString("name"));
it.setPhonenumber_seller(jsonObject1.getString("phonenumber_seller"));

The error ArrayIndexOutOfBoundsException: length=1; index=1 means your array at index 1 is not valid; in other words, you are trying to access the second element of an array that has only one element.
The below code will give a similar error:
public class ReplicateError {
public static void main(String args[]) {
// reproducing java.lang.ArrayIndexOutOfBoundsException : 1 error
String[] clients = {"John"};
String client = clients[1];
// this will throw java.lang.ArrayIndexOutOfBoundsException : 1
System.out.println(client);
}
}
I suggest you do a bound check:
if (args.length < 2) {
System.err.println("Not enough arguments received.");
return;
}

Best Approach using Volley Android to Insert SQLITE Database?

I'm using Volley in my android application but I'm facing a problem, I have to use volley only for async connections?
Because per example I have an 1800 record database from web service to my application I start my volley and retrieve fine but I'm inserting this records on my SQLite and when I do that my application freezy why?
I thinking volley have async methods to handle this but it freezy when I loop on a volley and insert. My dialogue stops animation and everything.
Before volley I use the Assyntask from android and never freezy my application and I'm using httpost but now I change to volley and I'm facing this issue I will share my code :
public void volleyJsonObjectRequest(String url) {
String REQUEST_TAG = "com.androidtutorialpoint.volleyJsonObjectRequest";
pDialog = new ProgressDialog(getActivity());
pDialog.setMessage("Sincronizando pedidos..");
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
pDialog.show();
// prepare the Request
JsonObjectRequest getRequest = new JsonObjectRequest(Request.Method.GET, url, null,
new Response.Listener<JSONObject>()
{
#Override
public void onResponse(JSONObject response) {
// display response
Log.d("Response", response.toString());
List<HashMap<String,String>> listObjectsServer = new ArrayList<>();
try {
MDAutomap controller;
controller = new MDAutomap(getActivity());
JSONArray jsonArrayPedidos = response.getJSONArray("pedidos");
if (jsonArrayPedidos != null && jsonArrayPedidos.length() > 0) {
HashMap<String, String> pedidos = new HashMap<String, String>();
for (int i = 0; i < jsonArrayPedidos.length(); i++) {
JSONObject obj = jsonArrayPedidos.getJSONObject(i);
pedidos.put("nomeusuario", obj.getString("nomeUsuario"));
pedidos.put("id", obj.getString("id"));
pedidos.put("nome", obj.getString("nome"));
pedidos.put("eventoid", obj.getString("eventoid"));
pedidos.put("descricao", obj.getString("descricao"));
pedidos.put("valor", obj.getString("valor"));
pedidos.put("veiculo", obj.getString("veiculo"));
pedidos.put("transactioncode", obj.getString("transactioncode"));
pedidos.put("referencecode", obj.getString("referencecode"));
pedidos.put("status", obj.getString("status"));
pedidos.put("flag", obj.getString("flag"));
pedidos.put("usuario", obj.getString("usuario"));
pedidos.put("created_at", obj.getString("created_at"));
pedidos.put("updated_at", obj.getString("updated_at"));
if (controller.checkPedido(pedidos.get("id"))) {
controller.updatePedido(pedidos);
}else {
controller.inserirPedido(pedidos);
}
}
if (pDialog != null && pDialog.isShowing()) {
pDialog.dismiss();
}
//userMsg("Sincronizado com sucesso os pedidos.");
}else {
if (pDialog != null && pDialog.isShowing()) {
pDialog.dismiss();
}
//userMsg("Não existe pedidos para sincronizar.");
}
} catch (JSONException e1) {
e1.printStackTrace();
}
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error) {
error.printStackTrace();
if (pDialog != null && pDialog.isShowing()) {
pDialog.dismiss();
}
userMsg("Não foi possível fazer conexão, por favor tenta novamente.");
}
}
);

Yes it will freeze because it is getting huge data from service and inserting in Db on main UI thread . So i solved that problem by taking a async task inside volley response and it worked in my case
private void hitApiForSyncDropdownsData(final String ApiType) {
showDialog();
String jsonAsParamstr = makeJsonStr(ApiType);
JsonObjectRequest req = new JsonObjectRequest(wholeUrl, makeJsonFromStrJson(jsonAsParamstr),
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
if (response.getString(Constant.Utils.responseCode).equals("1")) {
new ProcessJsonAsync(ApiType).execute(response, null, null);
//processing response in Async as getting heavy reponse and inserting into DB
} else {
showShortToast(response.getString(Constant.Utils.responseMessage));
dismissDialog();
}
} catch (JSONException e) {
e.printStackTrace();
dismissDialog();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.e("Error: ", error.getMessage());
showmsgForVolleyIfConnProb(error, context);
}
});
req = setretryPolicy(req);
AppController.getInstance().addToRequestQueue(req);
}
and that async Code would look like
private class ProcessJsonAsync extends AsyncTask<JSONObject, Void, Integer> {
String ApiType;
ProcessJsonAsync(String ApiType) {
this.ApiType = ApiType;
}
protected Integer doInBackground(JSONObject... jsonObjects) {
ArrayList<DataModel> dataModelArraylist = new ArrayList<>();
Integer insertedResult = -1;
try {
JSONObject response = jsonObjects[0];
if (response.getString(Constant.Utils.responseCode).equalsIgnoreCase("1")) {
JSONArray jsonarray = response.getJSONArray(Constant.Utils.responseObject);
for (int i = 0; i < jsonarray.length(); i++) {
JSONObject jsonObj = jsonarray.getJSONObject(i);
dataModelArraylist.add(new DataModel(jsonObj.getString("data1"), jsonObj.getString("data2"));
}
DataStrucTable dataStrucTable=new DataStructTable();
insertedResult=dataStrucTable.insertArrayInDb(dataModelArraylist);
//here it will insert thousands of entries in DB on background thread and will not hang your UI
}
} catch (JSONException e) {
e.printStackTrace();
}
return insertedResult;
}
#Override
protected void onPostExecute(Integer integer) {
Toast.makeText(context, integer == -1 ? "Data couldn't insert in DB" :"Data successfully inserted", Toast.LENGTH_SHORT).show();
}
}

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() );
}
})

Adding an array in params.put to volley request in android

I'm using Volley to interact with an API. I need to send a post request (with parameters) to a service that returns a JSON Array.
My Api code is having a function like:
public function Add($tripData) {
$response = "Unsuccessful";
if (isset($tripData)) {
//print_r($tripData);
$tripsModel = new TasksModel();
$tripsModel->user_id = $tripData["user_id"];
$tripsModel->date = $tripData["date"];
$tripsModel->latitude = $tripData["latitude"];
$tripsModel->longitude = $tripData["longitude"];
$tripsModel->location = $tripData["location"];
$tripsModel->notes = $tripData["notes"];
$tripsModel->trip = $tripData["trip"];
$tripsModel->city = $tripData["city"];
$method = new CommonMethods();
$response = $method->save("locationdetails", $tripsModel);
}
echo json_encode($response);
}
I just need to put params.put("data", data) to be in following kind of array:
$taskData["user_id"]=2;
$tripData["date"]="2015-06-02 16:01";
$tripData["latitude"]="41.213181";
$tripData["longitude"]="-124.004631";
$tripData["location"]="Redwood National";
$tripData["notes"]="hello";
$tripData["trip"]=3;
$tripData["city"]="California";
so that it could be used as:
$obj = new Myclass;
$var = $obj->Add($tripData);
I have checked the service already but could not post it from android code using hashmap.
private void insertTripData(final String[] tripData) {
// TODO Auto-generated method stub
// Tag used to cancel the request
String tag_string_req = "req_login";
StringRequest strReq = new StringRequest(Method.POST,
AppConfig.URL_REGISTER, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d("inserttrip",
"inserttrip Response: " + response.toString());
try {
JSONObject jObj = new JSONObject(response);
boolean error = jObj.getBoolean("error");
// Check for error node in json
if (!error) {
// user successfully logged in
// Create login session
// Launch main activity
Toast.makeText(getApplicationContext(),
"user data inserted", Toast.LENGTH_LONG)
.show();
} else {
// Error in login. Get the error message
String errorMsg = jObj.getString("error_msg");
// String errorMsg =
// "Please check your network connection";
Toast.makeText(getApplicationContext(),
errorMsg, Toast.LENGTH_LONG).show();
}
} catch (JSONException e) {
// JSON error
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("insertTripError",
"Data Error: " + error.getMessage());
String errorMsg = "Please check your network connection";
Toast.makeText(getApplicationContext(), errorMsg,
Toast.LENGTH_LONG).show();
}
}) {
#Override
protected HashMap<String, String> getParams() {
// Posting parameters to login url
JSONObject jsonObject = new JSONObject();
for (int i = 0; i <= tripData.length; i++) {
tripData[i] = "questionId_" + i + "_" + "ans_" + i;
try {
jsonObject.put("params_" + i, tripData[i]);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
String data= jsonObject.toString();
HashMap<String, String> params = new HashMap<String, String>();
params.put("tag", "trip");
params.put("action", "add");
params.put("data", data);
return params;
}
};
// Adding request to request queue
AppController.getInstance().addToRequestQueue(strReq, tag_string_req);
}

You said, getting "ArrayIndexOutOfBound" error in your logcat.
May be problem with your getParams() method.
Change the for loop this:
for (int i = 0; i <= tripData.length; i++)
To:
for (int i = 0; i < tripData.length; i++)
Check now and if you get any other problem, please show your logcat here,.
