While i am hitting URL to get response from server using volley ,during the fetching the net was disconnected .
my question is how to fetch data from server after reconnect the internet connection ,without hitting url once again
private void PostRequest(String Url) {
mRequest = new ServiceRequest(HomeActivity.this);
mRequest.makeServiceRequest(Url, Request.Method.GET, null, new ServiceRequest.ServiceListener() {
#Override
public void onCompleteListener(String response) {
Log.d("reponse", response);
JSONObject object = new JSONObject(response);
}
#Override
public void onErrorListener() {
indicator.setVisibility(View.GONE);
}
});
public void makeServiceRequest(final String url, int method, final
HashMap<String, String> param,ServiceListener listener) {
this.mServiceListener=listener;
stringRequest = new StringRequest(method, url, new Response.Listener<String>
() {
#Override
public void onResponse(String response) {
try {
mServiceListener.onCompleteListener(response);
} catch (Exception e) {
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
try {
if (error instanceof TimeoutError || error instanceof
NoConnectionError) {
} else if (error instanceof AuthFailureError) {
} else if (error instanceof ServerError) {
} else if (error instanceof NetworkError) {
} else if (error instanceof ParseError) {
}
} catch (Exception e) {
}
mServiceListener.onErrorListener();
}
}) {
#Override
protected Map<String, String> getParams() throws AuthFailureError {
return param;
}
#Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> headers = new HashMap<String, String>();
return headers;
}
};
//to avoid repeat request Multiple Time
DefaultRetryPolicy retryPolicy = new DefaultRetryPolicy(0, -1,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT);
stringRequest.setRetryPolicy(retryPolicy);
stringRequest.setRetryPolicy(new DefaultRetryPolicy(30000,
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
stringRequest.setShouldCache(false);
AppController.getInstance().addToRequestQueue(stringRequest);
}
}
please give suggetion,before hitting url i was checked internet connection
You can do one thing, create the collection of your failed requests. Register the broadcast receiver of CONNECTIVITY_CHANGE and WIFI_STATE_CHANGED to get notified when the internet connection is available. Once your device connects to the internet, you will get notified in registered broadcast receiver and then send retry all the request which are there in your collection. Once request is successful remove the request from the collection.
You can do with a Network Change Broadcast receiver.
Create a new class NetWorkChangeReceiver
public class NetWorkChangeReceiver extends BroadcastReceiver {
#NonNull
private final NetworkConnectionRestoredListener mListener;
public NetWorkChangeReceiver(#NonNull NetworkConnectionRestoredListener listener) {
mListener = listener;
}
#Override
public void onReceive(Context context, Intent intent) {
if (NetworkUtil.isDeviceConnectedToInternet(context)) {
mListener.onNetworkRestored();
}
}
public interface NetworkConnectionRestoredListener {
void onNetworkRestored();
}
}
Create a NetworkUtil class
#SuppressWarnings("deprecation")
public class NetworkUtil {
private NetworkUtil() {
// no instances
}
public static boolean isDeviceConnectedToInternet(#NonNull Context context) {
ConnectivityManager connManager = (ConnectivityManager) context.getSystemService(
CONNECTIVITY_SERVICE);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
for (Network network : connManager.getAllNetworks()) {
if (network != null) {
final NetworkInfo networkInfo = connManager.getNetworkInfo(network);
if (networkInfo != null && networkInfo.isConnected()) {
return true;
}
}
}
return false;
} else {
NetworkInfo mWifi = connManager.getNetworkInfo(TYPE_WIFI);
if (mWifi != null && mWifi.isConnected()) {
return true;
}
NetworkInfo m3G = connManager.getNetworkInfo(TYPE_MOBILE);
if (m3G != null && m3G.isConnected()) {
return true;
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR2) {
NetworkInfo mEthernet = connManager.getNetworkInfo(TYPE_ETHERNET);
return mEthernet != null && mEthernet.isConnected();
} else {
return false;
}
}
}
}
In your activity, implement NetWorkChangeReceiver.NetworkConnectionRestoredListener
public class HomeActivity extends AppCompatActivity implements NetWorkChangeReceiver.NetworkConnectionRestoredListener {
NetWorkChangeReceiver mNetworkChangeReceiver;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.home_activity);
//Use this to register the receiver while making the server call.
context.registerReceiver(mNetworkChangeReceiver = new NetWorkChangeReceiver(this), new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION));
}
#Override
public void onNetworkRestored() {
Toast.makeText(this, "Connected", Toast.LENGTH_SHORT).show();
if (mNetworkChangeReceiver != null) {
try {
unregisterReceiver(mNetworkChangeReceiver);
mNetworkChangeReceiver = null;
}
catch (IllegalArgumentException e) {
e.printStackTrace();
}
}
}
#Override
protected void onStop() {
super.onStop();
if (mNetworkChangeReceiver != null) {
try {
unregisterReceiver(mNetworkChangeReceiver);
mNetworkChangeReceiver = null;
}
catch (IllegalArgumentException e) {
e.printStackTrace();
}

I have designed a code which leads to application not responding.
I have used okhttp3.WebSocket for continuous input stream of data on which i am deciding to start an IntentService which will be fetching data from server.
I have an IntentService; in onHandleIntent i am giving an service call for fetching data from the server(roughly 3 calls).
For Service call i am using AsyncTask of android inside which my WebConnectionManger class runs on different thread.
Inside websocket i am getting details of a particular record for which i am going to fetch the details from the service call.
For 5-6 such records my application runs fine, but if records get 80-100 my application do not respond at all and i get ANR.
I am using simple plain TCP request for this.
can any on tells me what is the actual issue and how i can get rid of it?
any help is appreciated.
i am pasting the code of WebSocket, AsyncTask(rest two have same implementation), WebConnectionManger class and IntentService class.

You may want to check what is blocking the main thread for more than 6 seconds.
Usually ANR happens when main thread is blocked for some time. 6-10 seconds.
I am facing the problem to create a new user on ejabberd server but sign in is working fine. i used the github repository (https://github.com/dilicode/LetsChat) for register the new user and chat between two and more users. I search on intenet, i found some way to register those are:
1.add
%% In-band registration
{access, register, [{allow, all}]}.
in access rules in ejabberd server and
2. also add
{mod_register, [
{access_from, register},
...
] ...
it in access rules of ejabberd server.

but i could not found any progress.please help me out. thanks in advance.
After struggle i found solution of this kind of problem. we need to do server side changes like:
step1:
step2:
step3:
after doing all these steps we will able to register new user on ejabberd server.
public void getTestDats(String unique_id) {
final String tag = "testList";
String url = Constants.BASE_URL + "test_module.php";
Map<String, String> params = new HashMap<String, String>();
params.put("user_id", SharedPreferenceUtil.getString(Constants.PrefKeys.PREF_USER_ID, "1"));
params.put("unique_id", unique_id);//1,2,3,4,5
DataRequest loginRequest = new DataRequest(Method.POST, url, params, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
switch (response.optInt("unique_id")) {
case 1:
//task 1
break;
case 2:
//task 2
break;
default:
//nothing
}
}
}, new ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
//I want to know which unique_id request is failed
}
});
loginRequest.setRetryPolicy(new DefaultRetryPolicy(20000, 0, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
AppController.getInstance().addToRequestQueue(loginRequest, tag);
}
I'm trying to identity which request is failed with having unique_id.
I'm calling getTestDats("1") function with unique_id. And function called 10 times and all the api call in addToRequestQueue.
When API go into Success part its working as per code.
But when API go into Error part I didn't identity the request.
Is there any way to know my request param so I can retry with particular unique_id request.
set a field in loginRequest and in onErrorResponse access the field like loginRequest.getUniqueId()
Alternatively, create a seperate class that implements Response.Listener and ErrorListener
Response Listener class:
public class MyReponseListener implements Response.Listener<JSONOBject>{
private long uniqId;
public MyResponseListener(long uniqId){
this.uniqId = uniqId;
}
#Override
public void onResponse(JSONObject response) {
System.out.println("response for uniqId " + uniqId);
// do your other chit chat
}
}
ErrorListener class:
public class MyErrorListener implements ErrorListener{
private long uniqId;
public MyErrorListener(long uniqId){
this.uniqId = uniqId;
}
#Override
public void onErrorResponse(VolleyError error) {
System.out.println("Error for uniqId : " + uniqId);
}
}
Now call it like:
DataRequest loginRequest = new DataRequest(Method.POST, url, params, new MyResponeListener(uniqId), new MyErrorListener(uniqId));
Now if you want some code of the calling class to be accessible in the ErrorListener class then do the following:
1. In calling class put the codes you want to access in methods
2. Create an interface with those method
3. The calling class will implement that interface
4. Pass the interface to constructor of the MyErrorListener or MyResponseListener
for example an activity calls the volley request, on error you want to show a message.
put that show error codes in a method:
public void showMessage(int errorCode){
//message according to code
}
now create an interface
public interface errorMessageInterface{
void showMessage(int errorCode);
}
the activity will implement errorMessageInterface and pass this to the constructor of MyErrorListener and save it in a field.
Inside onErrorResponse, you will call
field.showMessage()
You can parse error response in the same way as you parse success response. I use similar solution in my projects.
public class VolleyErrorParser {
private VolleyError mError;
private String mBody;
private int mUniqueId = -1;
public VolleyErrorParser(VolleyError e){
mError = e;
parseAnswer();
parseBody();
}
private void parseBody() {
if (mBody==null)
return;
try{
JSONObject response = new JSONObject(mBody);
mUniqueId = response.getOptInt("unique_id");
}catch (JSONException e){
e.printStackTrace();
}
}
private void parseAnswer() {
if (mError!=null&&mError.networkResponse!=null&&mError.networkResponse.data!=null){
mBody = new String(mError.networkResponse.data);
}
}
public String getBody(){
return mBody;
}
public int getUniqueId(){
return mUniqueId;
}
}
Use:
...
, new ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
int id = new VolleyErrorParse(error).getUniqueId();
switch (id) {
case -1:
//unique id not found in the answer
break;
case 1:
//task 1
break;
case 2:
//task 2
break;
default:
//nothing
}
}
}
...
Just add this code to identify which type of error you are facing.Add this in your onError() method :
if (error instanceof TimeoutError) {
Log.e(TAG, "TimeoutError");
} else if (error instanceof NoConnectionError) {
Log.e(TAG,"tNoConnectionError");
} else if (error instanceof AuthFailureError) {
Log.e(TAG,"AuthFailureError");
} else if (error instanceof ServerError) {
Log.e(TAG,"ServerError");
} else if (error instanceof NetworkError) {
Log.e(TAG,"NetworkError");
} else if (error instanceof ParseError) {
Log.e(TAG,"ParseError");
}
Log the unique_id before making a request i.e; after params.put("unique_id", unique_id);//1,2,3,4,5. And also once you get the response in onResponse() method. And cross verify what exactly is happening.
most of the solutions here will "work" but they are too complex .. for me :)
here is the simplest option with least code change I can think of:
...
final Map<String, String> params = new HashMap<String, String>();
params.put("user_id", SharedPreferenceUtil.getString(Constants.PrefKeys.PREF_USER_ID, "1"));
params.put("unique_id", unique_id);//1,2,3,4,5
DataRequest loginRequest = new DataRequest(Method.POST, url, params, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
switch (params.get("unique_id")) {
case 1:
//task 1
break;
case 2:
//task 2
break;
default:
//nothing
}
}
...
All the above answers seem to be correct.But i recommend you to do this in an optimized way. If you will add error handling code in all onErrorResponse() then it will create duplication. So create a seperate method in Utils or some other class and just call that method by passing error object to the method. Also you can inflate some dialog or toast to display an error message.
public static void handleError(final Context context, String alertTitle,
Exception exception, String logTag) {
if (context != null) {
if (exception instanceof TimeoutError)
message = context.getString(R.string.TimeoutError);
else if (exception instanceof NoConnectionError)
message = context.getString(R.string.NoConnectionError);
else if (exception instanceof AuthFailureError)
message = context.getString(R.string.AuthFailureError);
else if (exception instanceof ServerError)
message = context.getString(R.string.ServerError);
else if (exception instanceof NetworkError)
message = context.getString(R.string.NetworkError);
else if (exception instanceof ParseError)
message = context.getString(R.string.ParseError);
message = exception.getMessage();
DialogHelper.showCustomAlertDialog(context, null,
alertTitle, message, "ok",
new OnClickListener() {
#Override
public void onClick(DialogInterface dialog,
int which) {
}
}, null, null);
}
}
I think you have to make one conman method on Base class. As given bellow which I used in my code for calling php web api
/**
* <h1> Use for calling volley webService </h1>
*
* #param cContext Context of activity from where you call the webService
* #param mMethodType Should be POST or GET
* #param mMethodname Name of the method you want to call
* #param URL Url of your webService
* #param mMap Key Values pairs
* #param initialTimeoutMs Timeout of webService in milliseconds
* #param shouldCache Web Api response are stored in catch(true) or not(false)
* #param maxNumRetries maximum number in integer for retries to execute webService
* #param isCancelable set true if you set cancel progressDialog by user event
* #param aActivity pass your activity object

}
}
Please observe that here we make one interface for getting response and error.
Using Interface you can get method name on both response and error so you can identify which web api is successfully called and which give error. You should extend base class to Activity and also implement Interface which you made for getting volley response. Here in above code I show how to bind interface to activity. when you call api by passing activity context.
I am working on Android Chat app based on Smack 4.1.7.
I have created my XMPP related operations on Saperate class said MyXMPP.java.
and in my app's Application class i am initializing MyXMPP class objects.
my problem is, suppose we have user 1 and user 2. if user 1 sends message to user 2 then user 2 can get message but cant reply back. means if user 2 trying to reply then user 1 can not get user 2's reply.
in short if user 1 initiates chatting then, only user 1 can send message. user 2 can not send message to user 1 same Vice versa.

Volley works well when there is network but it goes weird when network drops.
When network is doping ie network strength is going down and i make a post request then nothing happens but once the network regain to full strength it makes the call to the previous post request not the new one?
when i clear the cache it works well...
how to solve this issue, why i am getting previous post response?
