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);

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);

I am going to use volley to get data
RequestQueue queue = Volley.newRequestQueue(SummaryPhoneActivity.this);
String url = "https://covid19storageservice.table.core.windows.net/COVID19Survey?sv=2019-02-02&ss=bfqt&srt=sco&sp=rwdlacup&se=2020-06-30T18:04:08Z&st=2020-03-30T10:04:08Z&spr=https&sig=Ei3Kcr6xT5e7znK4ebwx6%2FVS09Ia5pbD1lnWRBh6bm4%3D";
StringRequest stringRequest = new StringRequest(Request.Method.GET, url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d("response:", response);
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d("error:", error.toString());
}
}){
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("Content-Type", "application/json");
return params;
}
};
queue.add(stringRequest);
I can get error: com.android.volley.ClientError.
Above url is working on postman.
How can I use volley for above case. Thanks for your advance.
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.
I try to use GET on Volley , but i need send request to application/json .
I take a look for some answers , i try to use jsonBody , but it shows error:
null com.android.volley.ServerError
Here is my code:
public class MainActivity extends AppCompatActivity {
String url = "http://114.35.246.42:2212/MobileApp/DEST_WebService.asmx/GetNews";
JSONObject jsonBody;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try {
//I try to use this for send Header is application/json
jsonBody = new JSONObject("{\"type\":\"example\"}");
} catch (JSONException ex) {
ex.printStackTrace();
}
RequestQueue mQueue = Volley.newRequestQueue(getApplicationContext());
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(url, jsonBody,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d("TAG", response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("TAG", error.getMessage(), error);
}
});
mQueue.add(jsonObjectRequest);
}
}
Is any one can teach me how to fix this , any help would be appreciated.
Here is my url:
String url = "http://114.35.246.42:2212/MobileApp/DEST_WebService.asmx/GetNews";
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("Content-Type", "application/json");
return params;
}
Implementation in your's
public class MainActivity extends AppCompatActivity {
String url = "http://114.35.246.42:2212/MobileApp/DEST_WebService.asmx/GetNews";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
RequestQueue mQueue = Volley.newRequestQueue(getApplicationContext());
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(url, jsonBody,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d("TAG", response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("TAG", error.getMessage(), error);
}
}) { //no semicolon or coma
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("Content-Type", "application/json");
return params;
}
};
mQueue.add(jsonObjectRequest);
}
}
In general for setting a custom header you need to override getHeaders and set the custom header manually. However, volley handles content type headers differently and getHeaders way does not always work.
So for your case you need to override getBodyContentType. So your code will look like
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(url, jsonBody,new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
Log.d("TAG", response.toString());
}, new Response.ErrorListener(){
#Override
public void onErrorResponse(VolleyError error) {
Log.e("TAG", error.getMessage(), error);
}
}){
#Override
public String getBodyContentType(){
return "application/json";
}
};
I try to use GET on Volley
The docs for the method you are calling says this
Constructor which defaults to GET if jsonRequest is null, POST otherwise
You can't GET with an HTTP JSON body. Maybe that's the error.
//I try to use this for send Header is application/json
jsonBody = new JSONObject("{\"type\":\"example\"}");
That's not the header, so pass in null here to do GET
new JsonObjectRequest(url, null,
And towards the end of your request, override a method to request JSON
...
#Override
public void onErrorResponse(VolleyError error) {
Log.e("TAG", error.getMessage(), error);
}
}) { // Notice no semi-colon here
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("Content-Type", "application/json");
return params;
}
};
Use String request instead of jsonrequest like this
StringRequest loginMe = new StringRequest(Request.Method.GET, "http://114.35.246.42:2212/MobileApp/DEST_WebService.asmx/GetNews", new Response.Listener<String>() {
#Override
public void onResponse(String response) {
System.out.println("LoginActivity -- onResponse --> " + response);
if (progressDialog != null) {
progressDialog.dismiss();
}
try {
JSONObject jsonObject = new JSONObject(response);
} catch (Exception e) {
CommonUtility.somethingWentWrongDialog(activity,
"LoginActivity -- onResponse-- Exception --> ".concat(e.getMessage()));
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
if (progressDialog != null) {
progressDialog.dismiss();
}
CommonUtility.somethingWentWrongDialog(activity,
"LoginActivity -- onErrorResponse --> ".concat(error.getMessage()));
}
}) {
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<>();
System.out.println("LoginActivity -- LoginParams --> " + params.toString());
return params;
}
};
loginMe.setRetryPolicy(new DefaultRetryPolicy(60000, DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
Volley.newRequestQueue(activity).add(loginMe);
