Error 400 in android volley while using POST request method

I'm passing a key-value pair in String request using post request method I'm getting error 400.
The Error is:E/Volley: [1120] NetworkUtility.shouldRetryException: Unexpected response code 400 for http://11.1.1.86:9000/cef/investmentStrategies/android
RequestQueue MyRequestQueue = Volley.newRequestQueue(getContext());
url5 = "http://11.1.1.86:9000/cef/investmentStrategies/android";
StringRequest stringRequest5 = new StringRequest(Request.Method.POST, url5, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
System.out.println("No Error");
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
System.out.println("Error is here..");
}
}) {
#Nullable
#Override
protected Map<String, String> getParams() {
Map<String, String> MyData = new HashMap<String, String>();
MyData.put("Field",id);
return MyData;
}
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("Content-Type", "application/json");
return params;
}
};
MyRequestQueue.add(stringRequest5);
}

HTTP POST Request as a different Java Class - Android Studio

I am a complete noob to Android Studio, Java and Stack Overflow. My app performs a lot of HTTP Post requests using Volley and hence I've made an independent Java class with the code to perform the post request.
public class HTTPReq {
String[] finalResponse = new String[1];
public String postRequest(final HashMap<String,String> params, final Context context) {
RequestQueue requestQueue = Volley.newRequestQueue(context);
String url = "https://reqres.in/api/login";
StringRequest stringRequest = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
finalResponse[0] = response;
Toast.makeText(context, "2" + finalResponse[0], Toast.LENGTH_LONG).show();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
finalResponse[1] = error.getMessage();
//Toast.makeText(context, "Response Failed", Toast.LENGTH_LONG).show();
}
}) {
#Override
protected Map<String, String> getParams() {
return params;
}
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("Content-Type", "application/x-www-form-urlencoded");
return params;
}
};
requestQueue.add(stringRequest);
Toast.makeText(context, "3" + finalResponse[0], Toast.LENGTH_LONG).show();
return finalResponse[0];
}
}
What I'm trying to achieve is to get the response of the http request to the function call using return.
The function call is as follows:
public void login(String phno, String password,Context context)
{
HashMap<String,String> credentials = new HashMap<String, String>();
credentials.put("email","eve.holt#reqres.in");
credentials.put("password","cityslicka");
HTTPReq httpReq = new HTTPReq();
String response = httpReq.postRequest(credentials,context);
Toast.makeText(context, "1" + response, Toast.LENGTH_LONG).show();
}
I hope it's clear what I'm trying to achieve. Please help me with this.

your con use feature interface
public class HTTPReq {
public void postRequest(final HashMap<String, String> params, final Context context, final ResponseCallBack callBack) {
RequestQueue requestQueue = Volley.newRequestQueue(context);
String url = "https://reqres.in/api/login";
StringRequest stringRequest = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
callBack.onResponse(response);
Toast.makeText(context, response, Toast.LENGTH_LONG).show();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
callBack.onError(error);
Toast.makeText(context, "Response Failed", Toast.LENGTH_LONG).show();
}
}) {
#Override
protected Map<String, String> getParams() {
return params;
}
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("Content-Type", "application/x-www-form-urlencoded");
return params;
}
};
requestQueue.add(stringRequest);
}
}
calss interface :
import com.android.volley.VolleyError;
public interface ResponseCallBack<T> {
public void onResponse(T response);
public void onError(VolleyError error_response);
}
MainActivity:
public class MainActivity extends AppCompatActivity implements ResponseCallBack {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
HTTPReq httpReq = new HTTPReq();
HashMap<String, String> credentials = new HashMap<String, String>();
credentials.put("email", "eve.holt#reqres.in");
credentials.put("password", "cityslicka");
httpReq.postRequest(credentials, this, this);
}
#Override
public void onResponse(Object response) {
Log.e("TAG", "onResponse: " + response);
}
#Override
public void onError(VolleyError error_response) {
Log.e("TAG", "onError: " + error_response);
}

Android: How to call put method in Volley?

When i call URL on postman, it returns expected result. I use PUT method using Volley, but it does not work.
StringRequest reg=new StringRequest(Request.Method.PUT, AppConfig.Registration, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d("USER_REG",response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d("USER_REG","-------------"+error);
}
}){
#Override
protected Map<String,String> getParams(){
Map<String,String> params = new HashMap<String, String>();
params.put(name1,Name);
params.put(client_id1,CID);
params.put(email1,Email);
params.put(mobile1,Mobile);
params.put(password1,Password);
params.put(device_id1,"123456");
return params;
}
};
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(reg);
Here's the postman output.

Currently you are sending the data from your Android using Volley as path parameters which should be sent as JSON like the following.
RequestQueue queue = Volley.newRequestQueue(this);
private void makeJsonObjReq() {
Map<String, String> postParam= new HashMap<String, String>();
postParam.put(name1,Name);
postParam.put(client_id1,CID);
postParam.put(email1,Email);
postParam.put(mobile1,Mobile);
postParam.put(password1,Password);
postParam.put(device_id1,"123456");
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Method.PUT,
Const.YOUR_URL, new JSONObject(postParam),
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d(TAG, response.toString());
msgResponse.setText(response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
}
}) {
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json; charset=utf-8");
return headers;
}
};
jsonObjReq.setTag(TAG);
queue.add(jsonObjReq);
You need to add the Content-Type as application/json in the header as well.

Send int and String as param in volley

Am trying to send String and int as params in volley. But it show error on String if i use Map<String,Integer> params = new HashMap<String, String>(); and show error on int if i use Map<String,String> params = new HashMap<String, String>(); So how can i send int and String as a param in post request.
StringRequest stringRequest = new StringRequest(Request.Method.POST, "http://www.aaa.com/insert/signup" ,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.i("sign_up_res", response);
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("error" , error.toString());
}
}){
#Override
protected Map<String,String> getParams(){
Map<String,String> params = new HashMap<String, String>();
params.put("firstname" , PreferenceManager.getDefaultSharedPreferences(getApplicationContext()).getString(Local_Preference.FIRSTNAME, "Not Set") );
params.put("number" , "123");
return params;
}
};
stringRequest.setRetryPolicy(new DefaultRetryPolicy(
1000,
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
RequestQueue requestQueue = Volley.newRequestQueue(SignUp2Activity.this);
requestQueue.add(stringRequest);
In Sql table is like firstname (varchar) and number(int). I don't want to change the int type to varchar in sql. Is there any way to send int and String in a single params.

you can do this create a
Map params = new HashMap();
then
params.put(key,value); // for string
params.put(key,String.valueOf(value)); // for int As suggested

Please follow the code using this my problem is solved
String tag_json_obj = "json_obj_req";
String url = "https://api.androidhive.info/volley/person_object.json";
ProgressDialog pDialog = new ProgressDialog(this);
pDialog.setMessage("Loading...");
pDialog.show();
JsonObjectRequest jsonObjReq = new JsonObjectRequest(Method.POST,
url, null,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d(TAG, response.toString());
pDialog.hide();
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
VolleyLog.d(TAG, "Error: " + error.getMessage());
pDialog.hide();
}
}) {
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("name", "Androidhive");
params.put("email", "abc#androidhive.info");
params.put("password", "password123");
return params;
}
};
// Adding request to request queue
AppController.getInstance().addToRequestQueue(jsonObjReq, tag_json_obj);

How to send Post request using Volley in Android?

I am sending a volley request like this
btnSignUp.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//submitForm();
JsonObjectRequest jsonobjectRequest = new JsonObjectRequest(Request.Method.POST, URL, null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
//errorlabel.setText(response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
errorlabel.setText("Invalid username / password");
}
}){
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("email", "asd#asd.com");
params.put("password", "asd");
return params;
}
};
errorlabel.setText(jsonobjectRequest.toString());
requestQueue.add(jsonobjectRequest);
}
});
}
But I get an error message from the server saying invalid email/password.
I have set up the correct params. I tested it out on Postman and it works in there. Here is a screenshot.

I had same problem and i tried with String request, its working
StringRequest jsonObjRequest = new StringRequest(Request.Method.POST,
URL,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
}) {
#Override
public String getBodyContentType() {
return "application/x-www-form-urlencoded; charset=UTF-8";
}
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> postParam = new HashMap<String, String>();
postParam.put("email", "asd#asd.com");
postParam.put("password", "asd");
return postParam;
}
};
requestQueue.add(jsonObjRequest);
