Android Async Http Client - android

Hi i am using LoopJ lib to get response from server in json. But the problem is that at times i get org.apache.http.conn.ConnectTimeoutException and sometimes it runs fine. I am using the GET method. But when ever i copy and paste the URl to my Browser it runs fine But on the Android device i mostly cant connect to the server what is the problem. What am i doing wrong ?
client.setTimeout(timoutVal);
client.get(
"http://somewebsiteaddress.com/users.php?task=isUserPresent&email="
+ URLEncoder.encode(username) + "&password="
+ URLEncoder.encode(password) + "&licenseKey="
+ URLEncoder.encode(licKey), null,
new AsyncHttpResponseHandler() {
public void onSuccess(String response) {
loading.cancel();
Log.v("web response ", response);
try {
json = new JSONObject(response);
if (json.getBoolean("status")) {
delegate.Validation(
json.getBoolean("isUserPresent"),
json.getBoolean("license"), username,
password, json);
} else {
delegate.invalidLogin();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
#Override
public void onFailure(Throwable arg) {
Log.v("onFailure", arg + "");
loading.cancel();
delegate.InternetErrorDialog();
super.onFailure(arg);
}
});

Try to increase your timeout value.
The reason is client will try to get response until timeout value.
As soon as it exceeds the timeout value it will throw timeout exception.

While calling a post request through Retrofit getting 400 bad request error

Through Postman API is working but same API is not working with Retrofit
I am getting 400 Bad Request with Retrofit
End Point which returns true or false
#POST("/emrmegax/api/allscript/saveappointment")
Call saveAppointment (#Header("x-auth-token") String header1, #Body String yy);
and this is my method from where i am calling this above API
private void saveAppoint(String token, Saveappointment mSaveappointment){
APIInterface service = APIClient.getRetrofitInstance().create(APIInterface.class);
JSONObject paramObject = new JSONObject();
paramObject.put("ehrAppointmentId", "");
paramObject.put("ehrPatientId", mSaveappointment.getEhrPatientId());
paramObject.put("appointmentType", mSaveappointment.getAppointmentType());
paramObject.put("ehrProviderAbbrev", mSaveappointment.getEhrProviderAbbrev());
paramObject.put("ehrProviderId", mSaveappointment.getEhrProviderId());
paramObject.put("reason", mSaveappointment.getReason());
paramObject.put("startDateTime", mSaveappointment.getStartDateTime());
Call<Boolean> call = service.saveAppointment(token, paramObject.toString());
call.enqueue(new Callback<Boolean>() {
#Override
public void onResponse(Call<Boolean> call, Response<Boolean> response) {
progressDialog.dismiss();
//boolean value=response.body();
if (!response.isSuccessful()) {
Toast.makeText(mcontext, "" + response.code() + " " + response.body(), Toast.LENGTH_SHORT).show();
}
}
#Override
public void onFailure(Call<Boolean> call, Throwable t) {
Toast.makeText(mcontext, "" + t.getMessage(), Toast.LENGTH_SHORT).show();
}
});
}
A 400 Bad Request error means that the request the client made is incorrect or corrupt, and the server can't understand(parse) it.
Some causes of 400 Bad Request error:
Invalid url.
Invalid/Missing Header.
Maybe response error body contains some detailed message?

Android Volley onResponse function not running

Here is my function which I filled in from https://developer.android.com/training/volley/request#java
String url = "http://192.168.1.31:8000/api/social/convert-token";
JSONObject jsonBody = new JSONObject();
try{
jsonBody.put("grant_type", "convert_token");
jsonBody.put("client_id", clientID);
jsonBody.put("client_secret",clientSecret);
jsonBody.put("backend", "facebook");
jsonBody.put("token", facebookAccessToken);
jsonBody.put("user_type", userType);
}catch (JSONException e){
e.printStackTrace();;
}
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest
(Request.Method.POST, url, jsonBody, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
//Execute Code
Log.d("LOGIN TO SERVER", response.toString());
// Save server token to local DB
SharedPreferences.Editor editor = sharedPreferences.edit();
try {
editor.putString("token", response.getString("access_token"));
}catch (JSONException e){
e.printStackTrace();
}
editor.commit();
//Start home activity
startActivity(new Intent(Login.this,Home.class));
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
// TODO: Handle error
}
});
The string URL is my Django server, this works properly, I can access it from the web browser on the android phone.
The next block of just converts data I previously got into JSON format. I tested this by copying and pasting the URL, and each parameter in Postman, and it works and returns JSON back.
jsonBody is then passed into the Json Request, along with the URL. The Log.d "LOGIN TO SERVER", is not visible in my log. So I know that the onResponse does not run. Further I put a Log line in the onErrorResponse, and it was visible in my log.
So onReponse does not run, while onError response does. I don't know what the error is.
Three cases,
Check if there are any headers to pass using getHeaders().
2.As it is http and not https, provide android:usesCleartextTraffic="true" in manifest inside . It allows you to access http urls also.
3.You said you have kept logger in Response.onErrorListener(){} and what is the error. If not give it by Log.d("Error", "Error getting "+error.toString);

Session times out after 5 minutes, even though the session-timeout parameter is set to 30

I have an android app that sends a request to the server via Volley:
private void waitForForfeit(final String user_id, final String accessToken) {
String url = "";
RequestQueue queue = Volley.newRequestQueue(activity);
try {
url = "https://www.chiaramail.com:443/GameServer/GameServer?user_ID=" + URLEncoder.encode(user_id, "UTF-8") + "&token=" + URLEncoder.encode(accessToken, "UTF-8") + "&cmd=" + URLEncoder.encode("WAITFOR FORFEIT ", "UTF-8") + "&parms=" + URLEncoder.encode(user_id, "UTF-8");
} catch (UnsupportedEncodingException e) {
Toast.makeText(activity, getString(R.string.wait_forfeit_error) + e.getMessage(), Toast.LENGTH_LONG).show();
spinner.setVisibility(View.INVISIBLE);
waitForForfeit(user_id, accessToken);
}
StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>() {
#Override
public void onResponse(String response) {
if (!response.startsWith("41 ")) {
queue_builder.setMessage(getString(R.string.wait_forfeit_error) + " " + response);
queue_alert = queue_builder.create();
queue_alert.show();
} else {
forfeitAlert.show();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
volleyError = error;
Toast.makeText(activity, getString(R.string.wait_forfeit_error) + volleyError.getMessage(), Toast.LENGTH_LONG).show();
waitForForfeit(user_id, accessToken);
}
});
stringRequest.setRetryPolicy(new DefaultRetryPolicy(
60*1000*60,
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
// Add the request to the RequestQueue.
queue.add(stringRequest);
}
I've confirmed that the request is being received and processed correctly by the server. The request was designed to return only when a certain event has occurred (another app sends a request that results in the server returning a "41 " response) and this runs correctly.
The problem is that if the second app doesn't send its request within 5 minutes, then the first app experiences a VolleyError. This is even though the session timeout is set to 30 minutes:
<session-config>
<session-timeout>
60
</session-timeout>
</session-config>
Anyone here have a clue about why this is happening? I've Googled around for a five-minute timeout in Tomcat and couldn't find anything. I also grepped the server config files, looking for 300000, 300 and 600 (five minutes in ms, seconds and minutes) and there was nothing configured with any of these values. What am I missing? I've spent nearly a week on this and it's getting kinda old.
The five-minute timeout is from the Apache server, not Tomcat. After I changed the Timeout setting in the Apache httpd.conf file from 600 to -1, I got the unlimited timeout I was looking for.

how to solve 401 error

I am trying to sent JSON format data (using Volley) from two EditText-views and a method that return unique Device ID to a URL from my Android application and I receive
"[8970] BasicNetwork.performRequest: Unexpected response code 401 for https://gorountsiallyetlasornall:5wxGq5UNlY6wdWmNAyYPVVrN#bulberadev.cloudant.com/notebook"
Here is My method:
private void doPost() {
final String url = "https://gorountsiallyetlasornall:5wxGq5UNlY6wdWmNAyYPVVrN#bulberadev.cloudant.com/notebook";
final String deviceId = getDeviceId(getApplicationContext());
try {
try {
JSONObject jsonObject = new JSONObject();
String title = editTitle.getText().toString();
String content = editContent.getText().toString();
jsonObject.put("title", title);
jsonObject.put("content", content);
jsonObject.put("deviceId", "<" + deviceId + ">");
} catch (JSONException e) {
e.printStackTrace();
}
requestQueue = Volley.newRequestQueue(this);
JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST,
url, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
VolleyLog.v("Response:%n %s", response.toString(4));
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
// Log.e("VOLLEY", "ERROR");
}
});
requestQueue.add(jsonObjectRequest);
} catch (Exception e) {
e.printStackTrace();
}
}
it should be in a format :
{
"title":"Birth day",
"content":"Buy a gift for my mom!",
"deviceId":"<Device ID>"
}
A 401 is an Unauthorized error.
https://en.wikipedia.org/wiki/List_of_HTTP_status_codes#4xx_Client_Error
This means that the user and password is not getting recognized. You're providing it by means of the URL, but this only works for the browser. If the service you're using accepts Basic HTTP authorization headers, this code will provide you the needed headers:
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
HashMap<String, String> params = new HashMap<String, String>();
String creds = String.format("%s:%s","USERNAME","PASSWORD");
String auth = "Basic " + Base64.encodeToString(creds.getBytes(), Base64.DEFAULT);
params.put("Authorization", auth);
return params;
}
Original code from https://stackoverflow.com/a/18980454/3286819
Of course, username and password needs to be your own. In this case:
username: gorountsiallyetlasornall
password: 5wxGq5UNlY6wdWmNAyYPVVrN
URL: https://bulberadev.cloudant.com/notebook (notice I've removed the user and password)
Some more info: https://yakivmospan.wordpress.com/2014/04/04/volley-authorization/
Error 401 is an HTTP error for unauthorised. This is not a Volley or android related fault. In this case the URL you have provided
https://gorountsiallyetlasornall:5wxGq5UNlY6wdWmNAyYPVVrN#bulberadev.cloudant.com/notebook
Cannot be interpreted by Volley as a login either. This url is sometimes used by cURL and other tools to hardcode the username in password into the URI for Basic Authentication HTTP.
For this your username is gorountsiallyetlasornall and your password is 5wxGq5UNlY6wdWmNAyYPVVrN.
According to Basic Autentication, explained https://luckymarmot.com/paw/doc/HTTP_Basic_Auth
It needs to be converted to Base 64 then added to the header of the request.
I have converted your username and password into a Basic Auth base 64 encoded String for you bellow.
Z29yb3VudHNpYWxseWV0bGFzb3JuYWxsOjV3eEdxNVVObFk2d2RXbU5BeVlQVlZyTg==
Add this into your Volley header by extending a Volley request and overriding the function getHeaders to return a HashMap with the following key value pair.
"Authorization" , "Basic Z29yb3VudHNpYWxseWV0bGFzb3JuYWxsOjV3eEdxNVVObFk2d2RXbU5BeVlQVlZyTg"
Your request will now work.
Please let me know if you want a more detailed explanation.
PS. Hopefully the values you posted in your question is not your real username and password. If so, then don't do that in the future.

DefaultHttpClient change response size?

What I try to do
Hello Guys, I'm trying to create an App in which I can view the Orders the Customers gave to me. For this I created a interface on my server, on which I can send post/get/set request's. The response of the Server is in JSON-Format. (For your Information atm only dummydata is filled in)
Now when I do a get request from my app to the server, I get a response from it but it isn't complete about the half of the response I should get isn't there! :( But when I open the URL with the Get-Request in my browser, I get the full response.
Question
Like you see it can't be a server-based problem, because I also tryed via 'curl' to do this get requst, and allways got the full response.
In my App i work with the DefaultHttpClient, so I tought the Problem simply could be that there's a limit for the response but I didn't found it.
So where can I change this "response-size" and what else could be the problem why I don't get the full response! Some good code-snippets or whatever you can imagine would help!
Down here you'll find the code of the Methode which does the Get-Request.
Code
If you need more Code, just write it in the comments!
getOrders()
public void getOrders() {
Log.d("DataHandlerService", "Aufträge werden geladen");
Thread t = new Thread() {
public void run() {

Log.d("DataHandlerService", userid);
// Download-URL
String URL = "http://api.i-v-o.ch/users/" + userid
+ "/assignments.json";
Log.d("Request-URL", URL);
DefaultHttpClient client = new DefaultHttpClient();

BufferedReader rd = new BufferedReader(
new InputStreamReader(response.getEntity()
.getContent()));
String line;
while ((line = rd.readLine()) != null) {
sb.append(line + "\n");
}
String result;
result = sb.toString();
Log.d("Response", result);
JSONReader(result); //here the json will be generated
}
break;
case 500:
// Error-Handling
break;
}
} catch (Exception e) {
e.printStackTrace();
Log.e("DataHandler", "URLConnection-Error" + e);

Ah. Right, the problem isn't your connection or anything like that. Your service is returning an array - not an object - thus you should parse it like this:
HttpResponse response = ...
if (.. validate status ..) {
JSONArray array = new JSONArray(HttpEntityUtils.toString(response.getEntity()));
// Your JSONArray is now ready to play with.
}
And consider using an AsyncTask instead of a Thread, like this:
class AssignmentsTask extends AsyncTask<String, Void, JSONArray> {
#Override
protected JSONArray doInBackground(String... params) {
final String url = "http://api.i-v-o.ch/users/" + params[0]
+ "/assignments.json";
try {
HttpResponse response = mClient.execute(new HttpGet(url));
if (response.getStatusLine().getStatusCode() == 200) {
return new JSONArray(EntityUtils.toString(response.getEntity()));
} else {
Log.w(TAG, "Error receiving assignments for " + params[0] + ", " + response.getStatusLine());
}
} catch (ClientProtocolException e) {
Log.w(TAG, "Proto: Error fetching assignments for " + params[0], e);
} catch (IOException e) {
e.printStackTrace();
Log.w(TAG, "IO: Error reading assignments for " + params[0], e);
} catch (ParseException e) {
Log.w(TAG, "Parse: Error parsing assignments for " + params[0], e);
} catch (JSONException e) {
Log.w(TAG, "JSON: Error parsing JSON for " + params[0], e);
}
return null;
}
#Override
protected void onPostExecute(JSONArray result) {
// Stuff that handles the resulting JSONObject on
// the UI-thread goes here (i.e. update View:s)
// result is null if the operation failed
}
}
And to retrieve an order for the user "116":
new AssignmentsTask().execute("116");
The response size should be given by the web server you are contacting. You could read the response size using :
httpResponse.getEntity().getContentLength()
Also, what can happen is a connection timeout, making it impossible for the client to receive all data of the response. In that case, try using a timeout that is long enough to be sure you get all the data.
If your json is too large, then it's not a good idea in a mobile context to expect all the data coming in a single request, you could then have to design a web server that could give you chunks of a response, you would then require the first chunk, then the a different one, etc..
Usually, the http protocole's partial content is the answer for that problem.
