Multiple request at android volley

Multiple request at android volley - android

I get an error when I make multiple volley requests.
First, I am requesting login and it works fine. After the login process, the main activity opens in the application. When I make a new request here, the request is added to the queue. But the request is not executed. what is the reason of this?
This code is login function:
private void LoginUser(final String email, final String password) {
String tag_string_req = "request_register";
pDialog.setMessage("Giriş Yapılıyor ...");
showDialog();
StringRequest strReq = new StringRequest(Request.Method.POST,
URL_LOGIN, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
JSONObject jObj = new JSONObject(response);
boolean error = jObj.getBoolean("error");
if (!error) {
JSONObject user = jObj.getJSONObject("user");
int userId = user.getInt("UserId");
int uId = user.getInt("UId");
Intent intent = new Intent(LoginActivity.this, MainActivity.class);
intent.putExtra("UserId", userId);
intent.putExtra("UId", uId);
startActivity(intent);
finish();
} else {
String errorMsg = jObj.getString("message");
Toast.makeText(getApplicationContext(), errorMsg, Toast.LENGTH_LONG).show();
hideDialog();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(getApplicationContext(), error.getMessage(), Toast.LENGTH_LONG).show();
hideDialog();
}
}) {
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("email", email);
params.put("password", password);
return params;
}
};
strReq.setShouldCache(false);
LoginApplication.getInstance().addToRequestQueue(strReq, tag_string_req);
}
This code is get datas about user at after login function:
public void Sync(final Context context, final int uId)
{
String tag_string_req = "request_syncUser";
db1 = new Database(context);
StringRequest strReq = new StringRequest(Request.Method.POST,
URL_LOGIN, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
//gelen tüm verileri local db ye at
try {
SQLiteDatabase db = db1.getWritableDatabase();
JSONObject jObj = new JSONObject(response);
JSONArray responseUser = jObj.getJSONArray("user");
boolean error = jObj.getBoolean("error");
String message = jObj.getString("message");
if(!error) {
for(int i=0; i<responseUser.length(); i++)
{
JSONObject user = responseUser.getJSONObject(i);
String u_name = user.getString("Name");
String u_surname = user.getString("Surname");
String u_email = user.getString("Email");
String u_password = user.getString("Password");
String u_isLogin = user.getString("isLogin");
String u_isSync = user.getString("isSync");
int u_uId = user.getInt("UId");
ContentValues cv = new ContentValues();
cv.put("Name", u_name);
cv.put("Surname", u_surname);
cv.put("Email", u_email);
cv.put("Password", u_password);
cv.put("isLogin", u_isLogin);
cv.put("isSync", u_isSync);
cv.put("UId", u_uId);
db.insertOrThrow("user", null, cv);
Toast.makeText(context, message ,Toast.LENGTH_LONG).show();
Toast.makeText(context, u_name + u_surname,Toast.LENGTH_LONG).show();
}
} else {
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(context, error.getMessage(), Toast.LENGTH_LONG).show();
}
}) {
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<>();
params.put("uId", String.valueOf(uId));
return params;
}
};
strReq.setShouldCache(false);
LoginApplication.getInstance().addToRequestQueue(strReq, tag_string_req);
}
}

Well we need to see your code?
That said my guess is you are not creating / accessing your queue in a singleton pattern. Complete guess. Always always always post code.

How Can I use Post Method in Volley?

I want to know how can I POST Request Object in volley
class Request {
int restId;
List<Item> items;
}
class Item{
int itemId;
int count;
}

OnCreate():
RequestQueue requestQueue = Volley.newRequestQueue(this);
Example Post Method:
StringRequest postRequest = new StringRequest(Request.Method.POST, url1,
new Response.Listener<String>()
{
#Override
public void onResponse(String response)
{
try
{
System.out.println("response: " + response);
JSONObject jsonObject = new JSONObject(response);
String success = jsonObject.getString("success");
System.out.println("success: " + success);
// success-e gore usere info gosterilir
if (success.equals("true"))
{
Toast.makeText(SignUpActivity.this, R.string.register_success, Toast.LENGTH_SHORT).show();
Intent intent = new Intent(SignUpActivity.this, SignInActivity.class);
startActivity(intent);
}
else
{
String errorMessage = jsonObject.getString("message");
Toast.makeText(SignUpActivity.this, R.string.register_failed, Toast.LENGTH_SHORT).show();
}
}
catch (JSONException e)
{
e.printStackTrace();
}
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error)
{
Toast.makeText(SignUpActivity.this, "Something went wrong", Toast.LENGTH_SHORT).show();
}
}
)
{
#Override
protected Map<String, String> getParams()
{
Map<String, String> params = new HashMap<>();
params.put("name", nameText);
params.put("login", userNameText);
params.put("email", emailText);
params.put("password", passwordText);
if (!dateText.equals(""))
params.put("birthday", dateText);
return params;
}
};
requestQueue.add(postRequest);

There is no applicable constructor? Error appears on POST method in volley

The Problem was with my device. The Network mode was set to GSM Only. I Changed it to GSM/WCDMA auto and it worked. The Same Problem also occurs with Retrofit Http library. Retrofit returns Retrofit.Retrofit error. Hope this helps someone

Use Volley like this,... It is working for me.

First of all you are not sending json to your server. You are sending parametrized url with post method and getting json text as response.
I think the problem is the response from the server which is supposedly json. But from your log, this text "---- YOUR DATA ----" which you get from Log.d(TAG, "Register Response: " + response.toString()); is not at all json formatted . So you need to modify your server to respond in correct json format.

This is the solution. I had to use the JsonObjectRequest class and not the StringRequest on. What JsonRequest does is that it converts your HashMap key-value pairs into a JSON Format.
private void registerUser(String email_address,String username, String
password) {
String tag_json_obj = "json_obj_req";
final ProgressDialog pDialog = new ProgressDialog(this);
pDialog.setMessage("posting...");
pDialog.show();
final String mVendorId =
DeviceDetails.getInstance(mContext).getVendor_id();
String mUserId = UserModel.getInstance(mContext).getUser_id();
String location = getResources().getConfiguration().locale.getCountry();
final HashMap<String, String> postParams = new HashMap<String, String>
();
postParams.put("username", username);
postParams.put("email", email_address);
postParams.put("password", password);
postParams.put("location", location);
Response.Listener<JSONObject> listener;
Response.ErrorListener errorListener;
final JSONObject jsonObject = new JSONObject(postParams);
JsonObjectRequest jsonObjReq = new
JsonObjectRequest(AppConfig.URL_REGISTER, jsonObject,
new com.android.volley.Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
//Log.d("TAG", response.toString());
try {
Toast.makeText(getApplicationContext(),
response.getString("message"), Toast.LENGTH_LONG).show();
// Toast.makeText(getApplicationContext(), "Thank
you for your post", Toast.LENGTH_LONG).show();
if (response.getString("status").equals("success")){
session.setLogin(true);
pDialog.dismiss();
Intent i = new
Intent(RegisterActivity.this,Welcome.class);
startActivity(i);
