I want to call API Using Volley. There is an Multiple object Request So i don't Know Proper way. I was tried to code as below.But it does not give me Response.So can Anyone help me???
MainActivity
public void getJsonResponsePost(){
JSONObject jsonData = new JSONObject();
JSONObject json = new JSONObject();
/*{"data":{"lang_type":"1","keyword":"","latitude":23.022499999999997,"longitude":72.57139833333333,"category":6}}*/
try {
jsonData.put("data",json);
json.put("lang_type","1");
json.put("keyword","");
json.put("latitude",23.022499999999997);
json.put("longitude",72.57139833333333);
json.put("category",6);
Log.d("TAG",jsonData.toString());
} catch (JSONException e) {
e.printStackTrace();
}
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, url, json, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response)
{
Log.d("String Response :",response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d(" Error getting :",error.toString());
}
});
jsonObjectRequest.setTag(REQ_TAG);
requestQueue.add(jsonObjectRequest);
}
I get the following response
String Response :: {"status":"0","message":"Please pass the language type."}
Can you try this?
try {
json.put("lang_type","1");
json.put("keyword","");
json.put("latitude",23.022499999999997);
json.put("longitude",72.57139833333333);
json.put("category",6);
jsonData.put("data",json);
Log.d("TAG",jsonData.toString());
} catch (JSONException e) {
e.printStackTrace();
}
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, url, jsonData, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response)
{
Log.d("String Response :",response.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d(" Error getting :",error.toString());
}
});

I have a webservice which returns json files. If I call this url (http://192.168.178.67:8080/simplestock/webapi/swipeService/swipes/Aktien) on my smartphone browser, I will get a json array back.
Now I've tried to get this json in my android project with this code:
JsonArrayRequest jsonObjectRequest = new JsonArrayRequest
(Request.Method.GET, url, null, new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
Log.d("Success", "onResponse is Called");
try {
Log.d("Get Object: ", response.getJSONArray(1).toString());
} catch (JSONException e) {
e.printStackTrace();
Log.d("Failure", "JSON Error");
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d("JSON", "Error");
}
});
The problem is that the respond isn't called and I don't get any error message. I've added the internet permission in the manifest. I test on my smartphone, which is in the same network than the localhost. Anybody got an idea?
In what ever method you are calling your code you need to add the request to the queue: jsonObjectRequest.add(jsonArrayRequest);
Like this:
JsonArrayRequest jsonObjectRequest = new JsonArrayRequest
(Request.Method.GET, url, null, new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
Log.d("Success", "onResponse is Called");
try {
Log.d("Get Object: ", response.getJSONArray(1).toString());
} catch (JSONException e) {
e.printStackTrace();
Log.d("Failure", "JSON Error");
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d("JSON", "Error");
}
});
jsonObjectRequest.add(jsonArrayRequest);
I am fetching data from db and want to set text. Values are getting fetched and displaying in url but setText not working, when I used JSONObject also same problem. Where am I going wrong.? Below is my code and backend output.
{
"status": 200,
"db": {
"test_count": 2539,
"franchise_count": 2,
"patient_count": 1,
"invoice_count": 1,
"total_income": "12140",
"current_income": "12140",
"total_expense": null,
"current_expense": null,
"user_count": 2
}}
JsonObjectRequest objectRequest = new JsonObjectRequest(Request.Method.GET, url,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
progressDialog.dismiss();
try {
JSONObject object = new JSONObject();
u = object.getString("user_count");
user_count.setText(u);
} catch (JSONException e) {
Toast.makeText(getContext(),"No Records Found",Toast.LENGTH_LONG);
Log.e("Error", "Failed" +e.toString());
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
progressDialog.dismiss();
Log.e("Error", "Try Later" +error.toString());
Toast.makeText(getContext(),"No Records Found",Toast.LENGTH_LONG);
}
});
RequestQueue requestQueue = Volley.newRequestQueue(getActivity());
requestQueue.add(objectRequest);
}
Change your try block contents like below
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
progressDialog.dismiss();
try {
JSONObject newObject=response.getJSONObject("db");
u = newObject.getString("user_count");
user_count.setText(u);
} catch (JSONException e) {
Toast.makeText(getContext(),"No Records Found",Toast.LENGTH_LONG);
Log.e("Error", "Failed" +e.toString());
e.printStackTrace();
}
}
I have a POST method send a JsonObject via Volley:
JsonObjectRequest request = new JsonObjectRequest(Request.Method.POST, url, postBody, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
log("success");
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
log("" + error);
}
});
request.setRetryPolicy(new DefaultRetryPolicy(10000, 0, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
Volley.newRequestQueue(this).add(request);
With postBody:
JSONObject postBody = new JSONObject();
try {
postBody.put("name", "rome");
//postBody.put("image", file?);
} catch (JSONException e) {
log("" + e);
}
I want to send a image file with key "image" above. This file type is the same with file of form-data in PostMan (not url of file).
Is there anyway to do it? Thanks.
Good Day, I would like to get data from this url, and I have problems with onResponse method implementation:
I have something like this:
public void onClick(View v) {
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET, "http://horoscope-api.herokuapp.com/",
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
//The Problem is here
JSONArray jsonArray = response.getJSONArray("");
String author = jsonArray.getString(0);
textView.setText(author);
}catch(JSONException e){
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
}
);
requestQueue.add(jsonObjectRequest);
}
I don`t understand how to implement onResponse method correctly, I know that I must to get string from array or object, but data from link make me problems to understand what is it object or array, can you write me how to get author field from this url.
Thank you
Since the response in your link is JSONObject, you only need to do the following inside onResponse:
String author = response.getString("author");
textView.setText(author);
Hope this helps!
The response that you are getting is not a JSONArray but is a JSONObject. You could try the below code and see if you are able to get the author.
public void onClick(View v) {
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.GET, "http://horoscope-api.herokuapp.com/",
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
String author = response.get("author");
textView.setText(author);
}catch(JSONException e){
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
}
);
requestQueue.add(jsonObjectRequest);
}
Hope this helps.
The data from link is JSONObject not JSONArray. Call response.getString("author"); to get author string.
try{
String author = response.getString("author");
} catch(JSONException e) {
e.printStackTrace();
}
Hi I am a beginner in Android , I am learning to make Api Calls. I got a tutorial of Volley which uses GET to Receive response. Now I want to Send Post request Using Volley. I don't know how to do that, what would be the code for POST in the given Tutorial. Please guide me to send Post Request.The link to the tutorial that I am learning is http://www.truiton.com/2015/02/android-volley-example/
you have to used below code to send request
// Instantiate the RequestQueue.
RequestQueue queue = Volley.newRequestQueue(this);
String url ="http://www.google.com";
// Request a string response from the provided URL.
StringRequest stringRequest = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
// Display the first 500 characters of the response string.
mTextView.setText("Response is: "+ response.substring(0,500));
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
mTextView.setText("That didn't work!");
}
});
// Add the request to the RequestQueue.
queue.add(stringRequest);
try {
/** json object parameter**/
JSONObject jsonObject = new JSONObject();
jsonObject.put("hello", "hello");
Log.e("jsonObject params", jsonObject.toString() + "");
/**URL */
String url ="http://google.com"
progress.setVisibility(View.VISIBLE);
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, url, jsonObject, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject jsonObject) {
progress.setVisibility(View.GONE);
Log.e(TAG, "Response " + jsonObject.toString());
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError volleyError) {
progress.setVisibility(View.GONE);
Log.e(TAG, volleyError);
Util.showToast(activity, "Please try again");
}
});
requestQueue.add(jsonObjectRequest);
} catch (JSONException e) {
progress.setVisibility(View.GONE);
Log.e(TAG, e);
}
catch (Exception e) {
progress.setVisibility(View.GONE);
Log.e(TAG, e);
}
}
}
RequestQueue queue = Volley.newRequestQueue(this);
queue.add(jsonObjectRequest);
You can follow this :http://www.androidhive.info/2014/05/android-working-with-volley-library-1/
StringRequest request = new StringRequest(Method.POST,
"post url",
new ResponseListener() {
#Override
public void onResponse(String response) {
Log.d("response", response);
} catch (Exception e) {
e.printStackTrace();
}
}
}, new ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.e("response","error");
}
}) {
// post params
#Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("param", "param");
return params;
}
};
//2.Use your custom volley manager send request or like this
Volley.newRequestQueue(mCtx).add(request);
