I use Loop j for fetching data from server in my app. But it always fetch the old response . I test my api on postman and gets the latest response from server.
If any one know how to clear the loop j old response from cache?
Here is my code
AsyncHttpClient client = new AsyncHttpClient();
client.get("http://bnailsusa.com/app_api/getView.php?serviceprovider", new JsonHttpResponseHandler() {
#Override
public void onSuccess(int statusCode, cz.msebera.android.httpclient.Header[] headers, JSONArray response) {
Log.d("Tag:", String.valueOf(response));
try {
for (int i=0;i<=response.length();i++){
//region Fetching
JSONObject index=response.getJSONObject(i);
String name=index.getString("Name");
String spid=index.getString("spid");
String Photo=index.getString("PHOTO");
//endregion
//region Storing
names.add(name);
SPID.add(spid);
images.add(Photo);
Log.d("Tag:ar", String.valueOf(names));
//endregion
}
} catch (JSONException e) {
e.printStackTrace();
}
ProvidersAdapter booksAdapter = new ProvidersAdapter(SelectServiceProvider.this, names,images);
gridView.setAdapter(booksAdapter);
}
public void onFailure(int statusCode, cz.msebera.android.httpclient.entity.mime.Header[] headers, Throwable throwable, JSONObject errorResponse){
}
});

I am working on an Android app.
There is a recyclerview that shows user messages, and there is another recyclerview in the adapter from first recyclerview that shows responses from users to the messages.
It is working but not as I want.
The responses shown at each message are not always the responses related to the message.
For example, at message #3, there are shown the responses to message #3, at message #2 there are shown the responses to message #3 and #2, at message #1 there are shown the responses to message #3, #2 and #1.
After refreshing the view, this can be different, the responses shown may be different.
This is the piece of code inside the adapter that manages the responses recyclerview;
//respuestas
holder.recyclerViewPosts.setHasFixedSize(true);
holder.recyclerViewlayoutManager = new LinearLayoutManager(context);
holder.recyclerViewPosts.setLayoutManager(holder.recyclerViewlayoutManager);
subjectsList = new ArrayList<>();
AsyncHttpClient client = new AsyncHttpClient();
RequestParams params = new RequestParams();
params.put("origen", subjects.get(position).id_mensaje_chat);
params.put("rnd", getSaltString());
client.get(HTTP_JSON_URL, params, new TextHttpResponseHandler() {
#Override
public void onSuccess(int statusCode, Header[] headers, String res) {
// called when response HTTP status is "200 OK"
Log.d("RES SUVJETC","respuesta chat "+res);
try {
JSONArray jsonArray = new JSONArray(res);
for(int i = 0; i<jsonArray.length(); i++) {
MensajesRespuestaChat GetDataAdapter2 = new MensajesRespuestaChat();
JSONObject json = null;
try {
json = jsonArray.getJSONObject(i);
GetDataAdapter2.setid_respuesta(json.getString("id_respuesta"));
GetDataAdapter2.setemisor(json.getString("emisor"));
GetDataAdapter2.settexto(json.getString("texto"));
GetDataAdapter2.setfecha(json.getString("fecha"));
GetDataAdapter2.setorigen(json.getString("origen"));
GetDataAdapter2.setnombre(json.getString("nombre"));
GetDataAdapter2.setapellidos(json.getString("apellidos"));
} catch (JSONException e) {
e.printStackTrace();
}
subjectsList.add(GetDataAdapter2);
}
recyclerViewadapter = new RecyclerViewChatRespuestaCardViewAdapter(subjectsList, context);
holder.recyclerViewPosts.setAdapter(recyclerViewadapter);
Integer num_mensajes = subjectsList.size();
if (num_mensajes == 0){
}
if (num_mensajes > 0){
}
} catch (JSONException e) {
e.printStackTrace();
}
}
#Override
public void onFailure(int statusCode, Header[] headers, String res, Throwable t) {
// called when response HTTP status is "4XX" (eg. 401, 403, 404)
}
}
);
Maybe you can find the reason for that issue there.
If you need further pieces of code, I can put them here, no problem.
I am trying to do a get from the API, but it returns a 400, I have tried putting my local IP and putting 10.0.2.2, but he has continued to do the same, in the Event Log shows me this too: Emulator: CANNOT TRANSLATE guest DNS ip.From the PostMan I get the JSON back correctly so I do not think the problem is in the API
This is where I do everything
public void PendingTrajects(){
AsyncHttpClient client = new AsyncHttpClient();
String URL = "http://ip:port/api/trajectes";
client.get(this, URL, new AsyncHttpResponseHandler() {
#Override
public void onStart() {
Toast.makeText(PendingTrajectRecyclerView.this, "Carregant...", Toast.LENGTH_SHORT).show();
}
#Override
public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
JSONArray Usuaris = new JSONArray();
JSONArray trajectes = new JSONArray();
String Nom = null;
String strResponseBody = new String(responseBody);
try {
//Usuari = new JSONArray(strResponseBody);
trajectes = new JSONArray(strResponseBody);
}catch (JSONException e){
Toast.makeText(PendingTrajectRecyclerView.this, "Error a la connexió", Toast.LENGTH_SHORT).show();
}
try {
for(int i = 0; i < trajectes.length(); i++){
JSONObject trajecte = trajectes.getJSONObject(i);
JSONArray realitzas = trajecte.getJSONArray("realitzas");
for(int j = 0; j < realitzas.length(); j++){
JSONObject realitza = realitzas.getJSONObject(j);
JSONObject usuari = realitza.getJSONObject("usuari");
Log.d("xd", ""+usuari.getString("name"));
}
}
}catch (JSONException e){
Toast.makeText(PendingTrajectRecyclerView.this, "Error a la connexió", Toast.LENGTH_SHORT).show();
}
}
#Override
public void onFailure(int statusCode, cz.msebera.android.httpclient.Header[] headers, byte[] responseBody, Throwable error) {
Toast.makeText(PendingTrajectRecyclerView.this, "Error a la connexió ONFailure", Toast.LENGTH_SHORT).show();
Log.d("Error",""+statusCode);
}
});
400 BAD REQUEST
The server cannot or will not process the request due to something
that is perceived to be a client error (e.g., malformed request
syntax, invalid request message framing, or deceptive request
routing).
You should DEBUG your Application. Check your parameters.
Add a Break-point here
String URL = "http://ip:port/api/trajectes";
Actually server could not understand the request due to invalid syntax.
I'm trying to do a get with AsyncHttpClient, but doesn't enter in both methods, in Postman it's going well, any idea what could be?
AsyncHttpClient client = new AsyncHttpClient();
String URL = "http://link/link1/link2";
client.get(URL, new AsyncHttpResponseHandler() {
#Override
public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
JSONArray dni;
String strResponseBody = new String(responseBody);
try {
dni = new JSONArray(strResponseBody);
for(int i=0; i < dni.length(); i ++){
dniTemporal = dni.getString(i);
Log.d("DNI : ",""+ dniTemporal );
}
} catch (JSONException e) {
Toast.makeText(JourneyDetails.this, "Error", Toast.LENGTH_SHORT).show();
}
}
#Override
public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
Log.d("ERROR STATUS:"," "+ statusCode);
}
});
I am trying to get response from my node.js server with MySQL database.
When I connect to server with my browser I get result like this:
[{"person_id":0,"age":18},{"person_id":1,"age":17},{"person_id":2,"age":30}]
What I want to do is to get the same result with my Android app after pressing the button.
I wanted to use LoopJ AndroidAsyncHttp:
AsyncHttpClient client = new AsyncHttpClient();
client.get("http://localhost:3000", new JsonHttpResponseHandler() {
#Override
public void onSuccess(int statusCode, Header[] headers, JSONArray response) {
super.onSuccess(statusCode, headers, response);
}
});
I know that I connected to server properly because I got log in server's console.
What is the easiest way to retrieve that data?
Create a model Person contain "person_id" and "age"
AsyncHttpClient client = new AsyncHttpClient();
client.get("http://localhost:3000",new AsyncHttpResponseHandler() {
#Override
public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
try {
String response = responseBody == null ? null : new String(
responseBody, getCharset());
Log.d("Response: ", response);
Gson gson = new Gson();
Person[] arr = gson.fromJson(response, Person[].class);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
}
I'm using the Android Asynchronous Http Client. My code looks like this and is working fine.
DataUtil.post("RegisterUser", params, new AsyncHttpResponseHandler() {
#Override
public void onSuccess(String answer) {
// initialize variables
JSONObject json = new JSONObject();
String message = null;
try {
// turn string into JSONObject
json = new JSONObject(answer);
message = json.getString("message");
} catch (JSONException e) {
Log.e("ERROR", e.getMessage());
}
// registration was successful
if (message.equals("success")) {
// forward to login page
} else {
// error
}
}
});
I implemented a static HTTP Client. My server returns this JSON data {"message":"success"}. I do not want to treat it as a String and cast it back to JSON. But when I change it to public void onSuccess(JSONObject answer) eclipse tells me
The method onSuccess(JSONObject) of type new
AsyncHttpResponseHandler(){} must override or implement a supertype
method
The correct method signature would be this public void onSuccess(int statusCode, Header[] headers, JSONObject response) or any of the other available methods in the JsonHttpResponseHandler class
