Sending POST data in Android
(17 answers)
Closed 5 years ago.
I'm new to android and learning it now. I'm working on an application where I was able to get response form a get request successfully. Now I want to execute a POST request with a single parameter this is what I've came up with so far:
public class BGTask extends AsyncTask<String, String, String > {
#Override
protected String doInBackground(String... params) {
HttpURLConnection connection = null;
BufferedReader reader = null;
String color = "null";
try {
URL url = new URL(params[0]);
connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
//I want to pass the id parameter
connection.connect();
InputStream stream = connection.getInputStream();
reader = new BufferedReader(new InputStreamReader(stream));
StringBuffer buffer = new StringBuffer();
String line ="";
while ((line = reader.readLine()) != null){
buffer.append(line);
}
String finalJson = buffer.toString();
JSONObject parentObject = new JSONObject(finalJson);
int status = parentObject.getInt("status");
if(status == 1) {
color = parentObject.getString("bgcolor");
}
} catch (IOException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
} finally {
if(connection != null) {
connection.disconnect();
}
try {
if(reader != null) {
reader.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
return color;
}
}
The variable color is in hex code i.e #FF0089
** Use volley library for GET , POST and network calls it's very simple and efficient **
First create AppController.java
public class AppController extends Application {
public static final String TAG = AppController.class.getSimpleName();
private RequestQueue mRequestQueue;
private ImageLoader mImageLoader;
private static AppController mInstance;
#Override
public void onCreate() {
super.onCreate();
mInstance = this;
}
public static synchronized AppController getInstance() {
return mInstance;
}
public RequestQueue getRequestQueue() {
if (mRequestQueue == null) {
mRequestQueue = Volley.newRequestQueue(getApplicationContext());
}
return mRequestQueue;
}
public <T> void addToRequestQueue(Request<T> req, String tag) {
req.setTag(TextUtils.isEmpty(tag) ? TAG : tag);
getRequestQueue().add(req);
}
public <T> void addToRequestQueue(Request<T> req) {
req.setTag(TAG);
getRequestQueue().add(req);
}
public void cancelPendingRequests(Object tag) {
if (mRequestQueue != null) {
mRequestQueue.cancelAll(tag);
}
}
public ImageLoader getImageLoader() {
getRequestQueue();
if (mImageLoader == null) {
mImageLoader = new ImageLoader(this.mRequestQueue,
new LruBitmapCache());
}
return this.mImageLoader;
}
public void setConnectivityListener(ConnectivityReceiver.ConnectivityReceiverListener listener) {
ConnectivityReceiver.connectivityReceiverListener = listener;
}
}
Second make POST request
public void Send() {
final String First = "";
final String Second = "";
StringRequest stringRequest = new StringRequest(Request.Method.POST, CREATEORDER_URL,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.e("RESPONSE", response);
JSONObject jObj = null;
try {
jObj = new JSONObject(response);
String success = jObj.getString("success");
String errorMessage = jObj.getString("message");
if (success.equals("")) {
Intent intent = new Intent(SendGiftActivity.this, PayScreenActivity.class);
startActivity(intent);
finish();
} else {
Toast.makeText(SendGiftActivity.this, errorMessage, Toast.LENGTH_LONG).show();
}
} catch (JSONException e) {
e.printStackTrace();
}
// Toast.makeText(SignUpActivity.this, response, Toast.LENGTH_LONG).show();
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(SendGiftActivity.this, error.toString(), Toast.LENGTH_LONG).show();
}
}) {
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put(KEY_FIRST_PARAMETERS, First);
params.put(KEY_SECOND_PARAMETER, Second);
return params;
}
};
RequestQueue requestQueue = Volley.newRequestQueue(this);
requestQueue.add(stringRequest);
}
Include volley library
compile 'com.android.volley:volley:1.0.0'
Don't forget to add android:name=".AppController" in application tag of manifest file

I want to use Instagram data in my Android app without using API. I am having trouble because I haven't worked with .json and volley library before. With the link below, we can get the data of Instagram user as json.
Get Json Datas On Instagram:
https://www.instagram.com/android/?__a=1
I want to take this data as json in the Android application and take the username as an example. I tried a lot of things but I didn't get an answer. It gives errors and does not return any results. The reason I got the error is that I need to break up the data in two sets so that I can pull the data I want to get. So I couldn't find an answer and didn't get the username. I would be glad if you help. I'm sorry for my bad english. If what I wrote is incomprehensible, please refer to the codes and screenshot. You will definitely understand.
My Activity;
public class MainActivity extends AppCompatActivity {
private Button Find_Button;

pDialog.setMessage("Please wait...");
pDialog.setCancelable(false);
Find_Button = findViewById(R.id.button_login_01);
Find_Textview = findViewById(R.id.textview_login_01);
Find_Button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
makeJsonArrayRequest();
}
});
}

// Parsing json array response
// loop through each json object
jsonResponse = "";
for (int i = 0; i < response.length(); i++) {
JSONObject person = (JSONObject) response
.get(i);
JSONObject phone = person
.getJSONObject("graphql");
String name = phone.getString("username");
jsonResponse += "userName: " + name + "\n\n";

The json given by Insta is starting from JSONobject not JSONArray. Please make the following corrections in your code.

you problem is send server
Tell me if it is not resolved
I am trying to get posts from server based on a parameter i.e. email address. How do I send parameters in JSONArrayRequest so that only those posts are retrieved which are matched with the given parameter? Here is my code:
JsonArrayRequest:
JsonArrayRequest jsonArrayRequest = new JsonArrayRequest(url, new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
for(int i= 0; i<response.length(); i++){
try {
JSONObject object = response.getJSONObject(i);
Post post = new Post();
post.setContent(object.getString("Content"));
post.setDate(object.getString("PostDate"));
post.setTime(object.getString("PostTime"));
postArray.add(post);
PostList.notifyDataSetChanged();
} catch (JSONException e) {
e.printStackTrace();
}
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
});
AppController.getmInstance().addToRequestQueue(jsonArrayRequest);
And this is the AppController.Java class:
public class AppController extends Application {
private RequestQueue mRequestQueue;
private ImageLoader mImageLoader;
private static AppController mInstance;
public static final String TAG = AppController.class.getSimpleName();
#Override
public void onCreate() {
super.onCreate();
mInstance = this;
}
public static synchronized AppController getmInstance() {
return mInstance;
}
public RequestQueue getmRequestQueue()
{
if(mRequestQueue == null){
mRequestQueue = Volley.newRequestQueue(getApplicationContext());
}
return mRequestQueue;
}
public ImageLoader getmImageLoader(){
getmRequestQueue();
if(mImageLoader == null){
mImageLoader = new ImageLoader(this.mRequestQueue, new BitmapCache());
}
return mImageLoader;
}
public <T> void addToRequestQueue(Request<T> request, String tag ){
request.setTag(TextUtils.isEmpty(tag) ? TAG : tag);
getmRequestQueue(). add(request);
}
public <T> void addToRequestQueue(Request<T> request ){
request.setTag(TAG);
getmRequestQueue(). add(request);
}
public void cancelPendingRequest(Object tag){
if(mRequestQueue != null){
mRequestQueue.cancelAll(tag);
}
}
}
void MakePostRequest() {
StringRequest postRequest = new StringRequest(Request.Method.POST, EndPoints.BASE_URL_ADS,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
JSONObject jsonResponse = new JSONObject(response);
value1= jsonResponse.getString("Your ID1");
value2= jsonResponse.getString("Your ID2");
} catch (JSONException e) {
e.printStackTrace();
banner_id = null;
full_id = null;
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
error.printStackTrace();
value1= null;
value2= null;
}
}
) {
// here is params will add to your url using post method
#Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<>();
params.put("app", getString(R.string.app_name));
//params.put("2ndParamName","valueoF2ndParam");
return params;
}
};
Volley.newRequestQueue(this).add(postRequest);
}
this post request is using this compile 'com.mcxiaoke.volley:library:1.0.19' volley version.
i am just adding app name as parameter.you can add more params.
I created a JsonObjectRequest that I use to send a JSONObject to my WebService. When I try send this JSONObject the object is sending but send 3 objects instead 1. Looking in my data base there's 3 objects added.
I can't understand why this problem, because I always send 1 JSONObject but in webservice there's 3 objects.
I tried to use Postman of Google Chrome, and using Postman send 1 JSONObject normally.
What can be ?
JsonObjectRequest
public JsonObjectRequest sendContatoToEmpresa(String nome,
String email,
String telefone,

String mensagem,

Try to do the following:
app.setRetryPolicy(new DefaultRetryPolicy(
MY_SOCKET_TIMEOUT_MS,
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
Here you can change the timeout (MY_SOCKET_TIMEOUT_MS) and change the number of attempts (DefaultRetryPolicy.DEFAULT_MAX_RETRIES)
In my project I am use 3 layers: Activity, DAO and Web Service Transaction, layer Web Service Transaction has HttpClient to execute Get and Post in my web service.
An example to understand:
//structure
send: Activity->DAO->WebService
response: WebService->DAO->Activity
These works, but I'm using Threads and I don't want to use anymore threads. I want knows if there any way to create a generic AsyncTask that can return Boolean and List ?
Looking for a solution I founded this: Want to create a Generic AsyncTask but doesn't work to me, or I can't understand how this works.
How can I do to AsyncTask works in 3 layers as my project ?
So, here my real structure;

To my problem I resolved use Volley Library and now works.
I did this
Volley Singleton

private ImageLoader mImageLoader;
private static Context mCtx;
public static final String TAG = "VolleyPatterns";
private CustomVolleySingleton(Context context) {
mCtx = context;
mRequestQueue = getRequestQueue();
mImageLoader = new ImageLoader(mRequestQueue,

cache = new LruCache<String, Bitmap>(20);
#Override
public Bitmap getBitmap(String url) {
return cache.get(url);
}
#Override
public void putBitmap(String url, Bitmap bitmap) {
cache.put(url, bitmap);
}
});
}
public static synchronized CustomVolleySingleton getInstance(Context context) {
if (mInstance == null) {
mInstance = new CustomVolleySingleton(context);
}
return mInstance;
}
public RequestQueue getRequestQueue() {
if (mRequestQueue == null) {

}
return mRequestQueue;
