Android: Volley does not work offline with cache

I have added volley for request to get Json object, If wifi is turned on then it takes data but does not get in case of offline mode even cache is enabled for the request.
I do the following code
public class VolleySingleton extends Application
{
public static final String TAG = VolleySingleton.class.getSimpleName();
private RequestQueue mRequestQueue;
private static VolleySingleton mInstance;
private ImageLoader mImageLoader;
private final String DEFAULT_CACHE_DIR = "sl_cache";
#Override
public void onConfigurationChanged(Configuration newConfig)
{
super.onConfigurationChanged(newConfig);
}
#Override
public void onCreate()
{
super.onCreate();
mInstance = this;
}
public static synchronized VolleySingleton getInstance()
{
return mInstance;
}
public ImageLoader getImageLoader()
{
getRequestQueue();
if (mImageLoader == null)
{
mImageLoader = new ImageLoader(this.mRequestQueue, new LruBitmapCache());
}
return this.mImageLoader;
}
public <T> void addToRequestQueue(Request<T> req, String tag)
{
// set the default tag if tag is empty
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 RequestQueue getRequestQueue()
{
if (mRequestQueue == null)
{
Cache cache = new DiskBasedCache(getCacheDir(), 1024 * 1024 * 10); // 10MB cap
Network network = new BasicNetwork(new HurlStack());
mRequestQueue = new RequestQueue(cache, network);
mRequestQueue.start();
}
return mRequestQueue;
}
}
private void getData(String url, String tag)
{
final JsonObjectRequest jsonObjReq = new JsonObjectRequest(Request.Method.GET, url, null, new Response.Listener<JSONObject>()
{
#Override
public void onResponse(JSONObject response)
{
Log.wtf("HOME", response.toString());
String result = parseData(response.toString());
postProcessing(result);
//SocialLadder.getInstance().getRequestQueue().getCache().invalidate(url, true);
}
}, new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error)
{
VolleyLog.wtf("HOME", "Error: " + error.getMessage());
stopRefresher();
}
})
{
#Override
protected Response<JSONObject> parseNetworkResponse(NetworkResponse response)
{
try
{
String jsonString = new String(response.data, HttpHeaderParser.parseCharset(response.headers));
return !jsonString.isEmpty() ? Response.success(new JSONObject(jsonString), HttpHeaderParser.parseCacheHeaders(response)) : Response.success(new JSONObject(), HttpHeaderParser.parseCacheHeaders(response));
}
catch (JSONException ex)
{
ex.printStackTrace();
}
catch (UnsupportedEncodingException e)
{
e.printStackTrace();
}
return null;
}
};
jsonObjReq.setShouldCache(true);
VolleySingleton.getInstance().addToRequestQueue(jsonObjReq, tag);
}
Please help, I want to cache my screen data.
Edit
Cache Data
private String getCache(String url)
{
String data = "";
Cache cache = VolleySingleton.getInstance().getRequestQueue().getCache();
Cache.Entry entry = cache.get(url);
if (entry != null)
{
try
{
data = new String(entry.data, "UTF-8");
// handle data, like converting it to xml, json, bitmap etc.,
}
catch (UnsupportedEncodingException e)
{
e.printStackTrace();
}
}
/*else
{
// Cached response doesn't exists. Make network call here
}*/
return data;
}

Just add this line in **BasicNetwork* class or modify it as follow
#Override
public NetworkResponse performRequest(Request<?> request) throws VolleyError {
long requestStart = SystemClock.elapsedRealtime();
while (true) {
HttpResponse httpResponse = null;
byte[] responseContents = null;
Map<String, String> responseHeaders = Collections.emptyMap();
try {
if(!ConnectivityUtils.isNetworkEnabled(BBApplication.getContext())) {
return new NetworkResponse(HttpStatus.SC_NOT_MODIFIED,
request.getCacheEntry().data, responseHeaders, true);
}
// Gather headers.
Map<String, String> headers = new HashMap<String, String>();
addCacheHeaders(headers, request.getCacheEntry());
httpResponse = mHttpStack.performRequest(request, headers);
StatusLine statusLine = httpResponse.getStatusLine();
int statusCode = statusLine.getStatusCode();
responseHeaders = convertHeaders(httpResponse.getAllHeaders());
// Handle cache validation.
if (statusCode == HttpStatus.SC_NOT_MODIFIED) {
Cache.Entry entry = request.getCacheEntry();
if (entry == null) {
return new NetworkResponse(HttpStatus.SC_NOT_MODIFIED, null, responseHeaders, true, SystemClock.elapsedRealtime() - requestStart);
}
// A HTTP 304 response does not have all header fields. We
// have to use the header fields from the cache entry plus
// the new ones from the response.
// http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.3.5
entry.responseHeaders.putAll(responseHeaders);
return new NetworkResponse(HttpStatus.SC_NOT_MODIFIED, entry.data, entry.responseHeaders, true, SystemClock.elapsedRealtime() - requestStart);
}
// Some responses such as 204s do not have content. We must check.
if (httpResponse.getEntity() != null) {
responseContents = entityToBytes(httpResponse.getEntity());
} else {
// Add 0 byte response as a way of honestly representing a
// no-content request.
responseContents = new byte[0];
}
// if the request is slow, log it.
long requestLifetime = SystemClock.elapsedRealtime() - requestStart;
logSlowRequests(requestLifetime, request, responseContents, statusLine);
if (statusCode < 200 || statusCode > 299) {
throw new IOException();
}
return new NetworkResponse(statusCode, responseContents, responseHeaders, false, SystemClock.elapsedRealtime() - requestStart);
} catch (SocketTimeoutException e) {
attemptRetryOnException("socket", request, new TimeoutError());
} catch (ConnectTimeoutException e) {
attemptRetryOnException("connection", request, new TimeoutError());
} catch (NoHttpResponseException e) {
attemptRetryOnException("socket", request, new TimeoutError());
} catch (UnknownHostException e) {
attemptRetryOnException("socket", request, new TimeoutError());
} catch (MalformedURLException e) {
throw new RuntimeException("Bad URL " + request.getUrl(), e);
} catch (IOException e) {
int statusCode = 0;
NetworkResponse networkResponse = null;
if (httpResponse != null) {
statusCode = httpResponse.getStatusLine().getStatusCode();
} else {
throw new NoConnectionError(e);
}
VolleyLog.e("Unexpected response code %d for %s", statusCode, request.getUrl());
if (responseContents != null) {
networkResponse = new NetworkResponse(statusCode, responseContents, responseHeaders, false, SystemClock.elapsedRealtime() - requestStart);
if (statusCode == HttpStatus.SC_UNAUTHORIZED || statusCode == HttpStatus.SC_FORBIDDEN) {
attemptRetryOnException("auth", request, new AuthFailureError(networkResponse));
} else {
// TODO: Only throw ServerError for 5xx status codes.
throw new ServerError(networkResponse);
}
} else {
throw new NetworkError(networkResponse);
}
}
}
}
and for data request expiry you can change the Cached.Entry using using own HttpHeaderParser
Click for BasicNetwork
What is this code will do it will check for internet connection and Network call and revert if it has cached copy .
Note The API response should be cache-able because Volley only cache data if Response Header permits . See here for Cached Control Header

In order to cache anything with Volley you need to have two things:
1) server allows you to cache it. it usually appears in a cache control tag in the HTTP header.
2) you save it or in this scenario you tell the Volly to save.
so i think your problem is in number one. that means the server dose not allow you to cache those files, in order to confirm my answer you can do one of these things:
download this plug in (RESTClient) for mozilla and send your request and check the header file for cache control. if the server dose not allow you to cache you will see something like below image, notice cache control tag
set break point in headerValue = headers.get("Cache-Control"); at HttpHeaderParse class and see whats going on when Volley wants to parse the cache control tag.

Http Status Code in Android Volley when error.networkResponse is null

I am using Google Volley on the Android platform.
I am having a problem in which the error parameter in onErrorResponse is returning a null networkResponse
For the RESTful API I am using, I need to determine the Http Status Code which is often arriving as 401 (SC_UNAUTHORIZED) or 500 (SC_INTERNAL_SERVER_ERROR), and I can occasionally check via:
final int httpStatusCode = error.networkResponse.statusCode;
if(networkResponse == HttpStatus.SC_UNAUTHORIZED) {
// Http status code 401: Unauthorized.
}
This throws a NullPointerException because networkResponse is null.
How can I determine the Http Status Code in the function onErrorResponse?
Or, how can I ensure error.networkResponse is non-null in onErrorResponse?

Or, how can I ensure error.networkResponse is non-null in
onErrorResponse?
My first thought would be to check if the object is null.
#Override
public void onErrorResponse(VolleyError error) {
NetworkResponse networkResponse = error.networkResponse;
if (networkResponse != null && networkResponse.statusCode == HttpStatus.SC_UNAUTHORIZED) {
// HTTP Status Code: 401 Unauthorized
}
}
Alternatively, you could also try grabbing the Status Code by extending the Request class and overriding parseNetworkResponse.
For example, if extending the abstract Request<T> class
public class GsonRequest<T> extends Request<T> {
...
private int mStatusCode;
public int getStatusCode() {
return mStatusCode;
}
...
#Override
protected Response<T> parseNetworkResponse(NetworkResponse response) {
mStatusCode = response.statusCode;
try {
Log.d(TAG, "[raw json]: " + (new String(response.data)));
Gson gson = new Gson();
String json = new String(response.data, HttpHeaderParser.parseCharset(response.headers));
return Response.success(gson.fromJson(json, mClazz),
HttpHeaderParser.parseCacheHeaders(response));
} catch (UnsupportedEncodingException e) {
return Response.error(new ParseError(e));
} catch (JsonSyntaxException e) {
return Response.error(new ParseError(e));
}
}
...
}
Or, if you are using one of the toolbox classes that already extend the abstract Request<T> class and you don't want to muddle up the implementation for parseNetworkResponse(NetworkResponse networkResponse), continue overriding the method but return the super's implementation via super.parseNetworkResponse(networkResponse)
e.g. StringResponse
public class MyStringRequest extends StringRequest {
private int mStatusCode;
public MyStringRequest(int method, String url, Listener<String> listener,
ErrorListener errorListener) {
super(method, url, listener, errorListener);
}
public int getStatusCode() {
return mStatusCode;
}
#Override
protected Response<String> parseNetworkResponse(NetworkResponse response) {
mStatusCode = response.statusCode;
return super.parseNetworkResponse(response);
}
}
usage:
public class myClazz extends FragmentActivity {
private Request mMyRequest;
...
public void makeNetworkCall() {
mMyRequest = new MyNetworkRequest(
Method.GET,
BASE_URL + Endpoint.USER,
new Listener<String>() {
#Override
public void onResponse(String response) {
// Success
}
},
new ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
if (mMyRequest.getStatusCode() == 401) {
// HTTP Status Code: 401 Unauthorized
}
}
});
MyVolley.getRequestQueue().add(request);
}
Of course, the option to override the method inline is available too
public class MyClazz extends FragmentActivity {
private int mStatusCode;
...
public void makeNetworkCall() {
StringRequest request = new StringRequest(
Method.GET,
BASE_URL + Endpoint.USER,
new Listener<String>() {
#Override
public void onResponse(String response) {
// Success
}
},
new ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
if (mStatusCode == 401) {
// HTTP Status Code: 401 Unauthorized
}
}
}) {
#Override
protected Response<String> parseNetworkResponse(NetworkResponse response) {
mStatusCode = response.statusCode;
return super.parseNetworkResponse(response);
}
};
MyVolley.getRequestQueue.add(request);
}
Update:
HttpStatus is Deprecated. Use HttpURLConnection instead. See Link.

401 Not Supported by Volley
It turns out that it is impossible to guarantee that error.networkResponse is non-null without modifying Google Volley code because of a bug in Volley that throws the Exception NoConnectionError for Http Status Code 401 (HttpStatus.SC_UNAUTHORIZED) in BasicNetwork.java (134) prior to setting the value of networkResponse.
Work-Around
Instead of fixing the Volley code, our solution in this case was to modify the Web Service API to send Http Error Code 403 (HttpStatus.SC_FORBIDDEN) for the particular case in question.
For this Http Status Code, the value of error.networkResponse is non-null in the Volley error handler: public void onErrorResponse(VolleyError error). And, error.networkResponse.httpStatusCode correctly returns HttpStatus.SC_FORBIDDEN.
Other-Suggestions
Rperryng's suggestion of extending the Request<T> class may have provided a solution, and is a creative and excellent idea. Thank you very much for the detailed example. I found the optimal solution for our case is to use the work-around because we are fortunate enough to have control of the web services API.
I might opt for fixing the Volley code in one location within BasicNetwork.java if I did not have access to making a simple change at the server.

Volley supports HTTP 401 Unauthorized response. But this response MUST include "WWW-Authenticate" header field.
Without this header, 401 response causes "com.android.volley.NoConnectionError: java.io.IOException: No authentication challenges found" error.
For more detail : https://stackoverflow.com/a/25556453/860189
If you consume 3rd party API's and have no right to change response header, you may consider to implement your own HttpStack because of this exception thrown from HurlStack. Or better, use OkHttpStack as a HttpStack.

You may modify the volley library's performRequest me(toolbox/BasicNetwork.java) method to capture 401 Unauthorized response. (This modified code will also solve http-> https redirect problem of volley)
#Override
public NetworkResponse performRequest(Request<?> request) throws VolleyError {

if (responseContents != null) {

} else {
// TODO: Only throw ServerError for 5xx status codes.
throw new ServerError(networkResponse);
}
} else {
throw new NetworkError(e);
}
}
}
}
then in volley error handler use this code
#Override
public void onErrorResponse(VolleyError error) {
if (error instanceof AuthFailureError) {
//handler error 401 unauthorized from here
}
}
})
Happy coding :D

Network response can be received in the following format
NetworkResponse response = error.networkResponse;
if(response != null && response.data != null){
switch(response.statusCode){
case 403:
json = new String(response.data);
json = trimMessage(json, "error");
if(json != null) displayMessage(json);
break;
}
}

The error.networkResponse will be null, if the device has no network connection (you can proof this by enabling the airplane mode). Look at the corresponding code fragment from the Volley library.
You have to check then, if the error is an instance of the NoConnectionError, before you look for the networkResponse. I cannot agree, that 401 error is not supported by Volley, I tested it and got a non-null networkResponse object back with 401 status code. Look at the corresponding code here.

This is how I check and grep error.
// TimeoutError => most likely server is down or network is down.
Log.e(TAG, "TimeoutError: " + (e instanceof TimeoutError));
Log.e(TAG, "NoConnectionError: " + (e instanceof NoConnectionError));
/*if(error.getCause() instanceof UnknownHostException ||
error.getCause() instanceof EOFException ) {
errorMsg = resources.getString(R.string.net_error_connect_network);
} else {
if(error.getCause().toString().contains("Network is unreachable")) {
errorMsg = resources.getString(R.string.net_error_no_network);
} else {
errorMsg = resources.getString(R.string.net_error_connect_network);
}
}*/
Log.e(TAG, "NetworkError: " + (e instanceof NetworkError));
Log.e(TAG, "AuthFailureError: " + (e instanceof AuthFailureError));
Log.e(TAG, "ServerError: " + (e instanceof ServerError));
//error.networkResponse.statusCode
// inform dev
Log.e(TAG, "ParseError: " + (e instanceof ParseError));
//error.getCause() instanceof JsonSyntaxException
Log.e(TAG, "NullPointerException: " + (e.getCause() instanceof NullPointerException));
if (e.networkResponse != null) {
// 401 => login again
Log.e(TAG, String.valueOf(e.networkResponse.statusCode));
if (e.networkResponse.data != null) {
// most likely JSONString
Log.e(TAG, new String(e.networkResponse.data, StandardCharsets.UTF_8));
Toast.makeText(getApplicationContext(),
new String(e.networkResponse.data, StandardCharsets.UTF_8),
Toast.LENGTH_LONG).show();
}
}
else if (e.getMessage() == null) {
Log.e(TAG, "e.getMessage");
Log.e(TAG, "" + e.getMessage());
if (e.getMessage() != null && e.getMessage() != "")
Toast.makeText(getApplicationContext(),
e.getMessage(), Toast.LENGTH_LONG).show();
else
Toast.makeText(getApplicationContext(),
"could not reach server", Toast.LENGTH_LONG).show();
}
else if (e.getCause() != null) {
Log.e(TAG, "e.getCause");
Log.e(TAG, "" + e.getCause().getMessage());
if (e.getCause().getMessage() != null && e.getCause().getMessage() != "")
Toast.makeText(getApplicationContext(),
e.getCause().getMessage(), Toast.LENGTH_LONG).show();
else
Toast.makeText(getApplicationContext(),
"could not reach server", Toast.LENGTH_LONG).show();
}

I handle this problem manually:
Download Volley library from github and add into AndroidStudio project
Go to com.android.volley.toolbox.HurlStack class
Find setConnectionParametersForRequest(connection, request); line inside of performRequest method
And finally add this codes belew of setConnectionParametersForRequest(connection, request); line :
// for avoiding this exception : No authentication challenges found
try {
connection.getResponseCode();
} catch (IOException e) {
e.printStackTrace();
}

how to make HTTPS calls using AsyncHttpClient?

i was using AsyncHttpClient link for making http calls but now our server has migrated to HTTPS and I am getting exception javax.net.ssl.SSLPeerUnverifiedException: No peer certificate .
Has anyone tried making https call using this library ?
initialization of AsyncHttpClient :-
AsyncHttpClient client = new AsyncHttpClient();
PersistentCookieStore myCookieStore = new PersistentCookieStore(
getActivity());
// List<Cookie> cookies = myCookieStore.getCookies();
myCookieStore.clear();
// cookies = myCookieStore.getCookies();
client.setCookieStore(myCookieStore);
client.get(loginUrl, new JsonHttpResponseHandler() {
#Override

super.onStart();
progressBar.setVisibility(View.VISIBLE);
}
#Override
public void onFinish() {

progressBar.setVisibility(View.GONE);
}

public void onSuccess(int statusCode, JSONObject userInfo) {
super.onSuccess(statusCode, userInfo);
String errorMsg = null;
try {
errorMsg = userInfo.getString("error");
} catch (JSONException e) {
e.printStackTrace();
}
if (errorMsg != null) {
errorMsg = getActivity().getResources().getString(
R.string.loginFailure)
+ "\nError: " + errorMsg;
tvLoginFailure.setText(errorMsg);
tvLoginFailure.setVisibility(View.VISIBLE);
} else {
Subscriber.setEmail(email);
Subscriber.setPassword(password);
LoginUtility.saveUserInfo(getActivity(), userInfo);
if (Subscriber.getStatus().contentEquals("ACTIVE")) {
Intent intent;
if (MyApplication.ottMode) {
intent = new Intent(getActivity(),
OTTMainScreen.class);
} else {
intent = new Intent(getActivity(),
MainActivity.class);
intent.putExtra("SIGNEDIN", true);
}
if (MyApplication.ottMode) {
Utility.playSound(getActivity());
}
startActivity(intent);
getActivity().finish();
} else if (Subscriber.getStatus().contentEquals(
"SUSPENDED")) {
try {
String suspendedReason = userInfo
.getString("suspendreason");
if (suspendedReason != null
&& suspendedReason
.contentEquals("NO_SUBSCRIPTION")) {
new AlertDialog.Builder(getActivity())

}
})
.setNegativeButton("Cancel", null)
.show();
} else {

}
} else if (Subscriber.getStatus().contentEquals("INIT")) {
// TODO
}
}
}
#Override
public void onFailure(int statusCode,
org.apache.http.Header[] headers, String responseBody,

String msg = getActivity().getResources().getString(
R.string.loginFailure)
+ "\nError: " + responseBody;
tvLoginFailure.setText(msg);
tvLoginFailure.setVisibility(View.VISIBLE);
}
});

You need import the public server certificate into your default keystore, or if you are not interested in the authentication of your client you can initialize the AsyncHttpClient with
AsyncHttpClient asycnHttpClient = new AsyncHttpClient(true, 80, 443);
but this trick is not secure because use a custom SSLSocketFactory implementation whos omit the SSL certificate validation, take a look at the AsyncHttpClient source code.
More information about SSLSocketFactory at https://developer.android.com/reference/org/apache/http/conn/ssl/SSLSocketFactory.html

you can also solve this problem, with adding this 1 line.
asyncHttpClient.setSSLSocketFactory(MySSLSocketFactory.getFixedSocketFactory());

How to upload (put) image using Volley [duplicate]

Has anyone been able to accomplish sending a multipart/form-data POST in Android with Volley yet? I have had no success trying to upload an image/png using a POST request to our server and am curious if anyone has.
I believe the default way to do this would be to override public byte[] getPostBody() in the Request.java class and attach the File there with a blank Header key for the boundary. However, converting my file to a String for the Map<String, String> postParams and then having it encoded again seems obtuse and not really elegant. Also I've been unsuccessful in my attempts. This is really the only thing holding us back from switching to this library.
Anyway, all thoughts and answers are extremely appreciated. Thank you for your help.

I might be wrong on this but I think you need to implement your own com.android.volley.toolbox.HttpStack for this because the default ones (HurlStack if version > Gingerbread or HttpClientStack) don't deal with multipart/form-data.
Edit:
And indeed I was wrong. I was able to do it using MultipartEntity in Request like this:
public class MultipartRequest extends Request<String> {
private MultipartEntity entity = new MultipartEntity();
private static final String FILE_PART_NAME = "file";
private static final String STRING_PART_NAME = "text";
private final Response.Listener<String> mListener;
private final File mFilePart;
private final String mStringPart;
public MultipartRequest(String url, Response.ErrorListener errorListener, Response.Listener<String> listener, File file, String stringPart)
{
super(Method.POST, url, errorListener);
mListener = listener;
mFilePart = file;
mStringPart = stringPart;
buildMultipartEntity();
}
private void buildMultipartEntity()
{
entity.addPart(FILE_PART_NAME, new FileBody(mFilePart));
try
{
entity.addPart(STRING_PART_NAME, new StringBody(mStringPart));
}
catch (UnsupportedEncodingException e)
{
VolleyLog.e("UnsupportedEncodingException");
}
}
#Override
public String getBodyContentType()
{
return entity.getContentType().getValue();
}
#Override
public byte[] getBody() throws AuthFailureError
{
ByteArrayOutputStream bos = new ByteArrayOutputStream();
try
{
entity.writeTo(bos);
}
catch (IOException e)
{
VolleyLog.e("IOException writing to ByteArrayOutputStream");
}
return bos.toByteArray();
}
#Override
protected Response<String> parseNetworkResponse(NetworkResponse response)
{
return Response.success("Uploaded", getCacheEntry());
}
#Override
protected void deliverResponse(String response)
{
mListener.onResponse(response);
}
}
It's pretty raw but I tried it with an image and a simple string and it works. The response is a placeholder, doesn't make much sense to return a Response String in this case. I had problems using apache httpmime to use MultipartEntity so I used this https://code.google.com/p/httpclientandroidlib/ don't know if there's a better way.
Hope it helps.
Edit
You can use httpmime without using httpclientandroidlib, the only dependency is httpcore.

As mentioned in the presentation at the I/O (about 4:05), Volley "is terrible" for large payloads. As I understand it that means not to use Volley for receiving/sending (big) files. Looking at the code it seems that it is not even designed to handle multipart form data (e.g. Request.java has getBodyContentType() with hardcoded "application/x-www-form-urlencoded"; HttpClientStack::createHttpRequest() can handle only byte[], etc...). Probably you will be able to create implementation that can handle multipart but If I were you I will just use HttpClient directly with MultipartEntity like:
HttpPost req = new HttpPost(composeTargetUrl());
MultipartEntity entity = new MultipartEntity();
entity.addPart(POST_IMAGE_VAR_NAME, new FileBody(toUpload));
try {
entity.addPart(POST_SESSION_VAR_NAME, new StringBody(uploadSessionId));
} catch (UnsupportedEncodingException e) {
throw new RuntimeException(e);
}
req.setEntity(entity);
You may need newer HttpClient (i.e. not the built-in) or even better, use Volley with newer HttpClient

A very simple approach for the dev who just want to send POST parameters in multipart request.
Make the following changes in class which extends Request.java
First define these constants :
String BOUNDARY = "s2retfgsGSRFsERFGHfgdfgw734yhFHW567TYHSrf4yarg"; //This the boundary which is used by the server to split the post parameters.
String MULTIPART_FORMDATA = "multipart/form-data;boundary=" + BOUNDARY;
Add a helper function to create a post body for you :
private String createPostBody(Map<String, String> params) {
StringBuilder sbPost = new StringBuilder();
if (params != null) {
for (String key : params.keySet()) {
if (params.get(key) != null) {
sbPost.append("\r\n" + "--" + BOUNDARY + "\r\n");
sbPost.append("Content-Disposition: form-data; name=\"" + key + "\"" + "\r\n\r\n");
sbPost.append(params.get(key).toString());
}
}
}
return sbPost.toString();
}
Override getBody() and getBodyContentType
public String getBodyContentType() {
return MULTIPART_FORMDATA;
}
public byte[] getBody() throws AuthFailureError {
return createPostBody(getParams()).getBytes();
}

First answer on SO.
I have encountered the same problem and found #alex 's code very helpful. I have made some simple modifications in order to pass in as many parameters as needed through HashMap, and have basically copied parseNetworkResponse() from StringRequest. I have searched online and so surprised to find out that such a common task is so rarely answered. Anyway, I wish the code could help:
public class MultipartRequest extends Request<String> {
private MultipartEntity entity = new MultipartEntity();
private static final String FILE_PART_NAME = "image";
private final Response.Listener<String> mListener;
private final File file;
private final HashMap<String, String> params;
public MultipartRequest(String url, Response.Listener<String> listener, Response.ErrorListener errorListener, File file, HashMap<String, String> params)
{
super(Method.POST, url, errorListener);
mListener = listener;
this.file = file;
this.params = params;
buildMultipartEntity();
}
private void buildMultipartEntity()
{
entity.addPart(FILE_PART_NAME, new FileBody(file));
try
{
for ( String key : params.keySet() ) {
entity.addPart(key, new StringBody(params.get(key)));
}
}
catch (UnsupportedEncodingException e)
{
VolleyLog.e("UnsupportedEncodingException");
}
}
#Override
public String getBodyContentType()
{
return entity.getContentType().getValue();
}
#Override
public byte[] getBody() throws AuthFailureError
{
ByteArrayOutputStream bos = new ByteArrayOutputStream();
try
{
entity.writeTo(bos);
}
catch (IOException e)
{
VolleyLog.e("IOException writing to ByteArrayOutputStream");
}
return bos.toByteArray();
}
/**
* copied from Android StringRequest class
*/
#Override
protected Response<String> parseNetworkResponse(NetworkResponse response) {
String parsed;
try {
parsed = new String(response.data, HttpHeaderParser.parseCharset(response.headers));
} catch (UnsupportedEncodingException e) {
parsed = new String(response.data);
}
return Response.success(parsed, HttpHeaderParser.parseCacheHeaders(response));
}
#Override
protected void deliverResponse(String response)
{
mListener.onResponse(response);
}
And you may use the class as following:
HashMap<String, String> params = new HashMap<String, String>();
params.put("type", "Some Param");
params.put("location", "Some Param");
params.put("contact", "Some Param");
MultipartRequest mr = new MultipartRequest(url, new Response.Listener<String>(){
#Override
public void onResponse(String response) {
Log.d("response", response);
}
}, new Response.ErrorListener(){
#Override
public void onErrorResponse(VolleyError error) {
Log.e("Volley Request Error", error.getLocalizedMessage());
}
}, f, params);
Volley.newRequestQueue(this).add(mr);

Another solution, very light with high performance with payload large:
Android Asynchronous Http Client library:
http://loopj.com/android-async-http/
private static AsyncHttpClient client = new AsyncHttpClient();
private void uploadFileExecute(File file) {
RequestParams params = new RequestParams();
try { params.put("photo", file); } catch (FileNotFoundException e) {}
client.post(getUrl(), params,
new AsyncHttpResponseHandler() {
public void onSuccess(String result) {
Log.d(TAG,"uploadFile response: "+result);
};
public void onFailure(Throwable arg0, String errorMsg) {
Log.d(TAG,"uploadFile ERROR!");
};
}
);
}

Here is Simple Solution And Complete Example for Uploading File Using Volley Android
1) Gradle Import
compile 'dev.dworks.libs:volleyplus:+'
2)Now Create a Class RequestManager
public class RequestManager {
private static RequestManager mRequestManager;
/**
* Queue which Manages the Network Requests :-)
*/
private static RequestQueue mRequestQueue;
// ImageLoader Instance
private RequestManager() {
}
public static RequestManager get(Context context) {
if (mRequestManager == null)
mRequestManager = new RequestManager();
return mRequestManager;
}
/**
* #param context application context
*/
public static RequestQueue getnstance(Context context) {
if (mRequestQueue == null) {
mRequestQueue = Volley.newRequestQueue(context);
}
return mRequestQueue;
}
}
3)Now Create a Class to handle Request for uploading File WebService
public class WebService {
private RequestQueue mRequestQueue;
private static WebService apiRequests = null;
public static WebService getInstance() {
if (apiRequests == null) {
apiRequests = new WebService();
return apiRequests;
}
return apiRequests;
}
public void updateProfile(Context context, String doc_name, String doc_type, String appliance_id, File file, Response.Listener<String> listener, Response.ErrorListener errorListener) {
SimpleMultiPartRequest request = new SimpleMultiPartRequest(Request.Method.POST, "YOUR URL HERE", listener, errorListener);
// request.setParams(data);
mRequestQueue = RequestManager.getnstance(context);
request.addMultipartParam("token", "text", "tdfysghfhsdfh");
request.addMultipartParam("parameter_1", "text", doc_name);
request.addMultipartParam("dparameter_2", "text", doc_type);
request.addMultipartParam("parameter_3", "text", appliance_id);
request.addFile("document_file", file.getPath());
request.setFixedStreamingMode(true);
mRequestQueue.add(request);
}
}
4) And Now Call The method Like This to Hit the service
public class Main2Activity extends AppCompatActivity implements Response.ErrorListener, Response.Listener<String>{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
Button button=(Button)findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
uploadData();
}
});
}
private void uploadData() {
WebService.getInstance().updateProfile(getActivity(), "appl_doc", "appliance", "1", mChoosenFile, this, this);
}
#Override
public void onErrorResponse(VolleyError error) {
}
#Override
public void onResponse(String response) {
//Your response here
}
}

This is my way of doing it. It may be useful to others :
private void updateType(){
// Log.i(TAG,"updateType");
StringRequest request = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
// running on main thread-------
try {
JSONObject res = new JSONObject(response);
res.getString("result");
System.out.println("Response:" + res.getString("result"));
}else{
CustomTast ct=new CustomTast(context);
ct.showCustomAlert("Network/Server Disconnected",R.drawable.disconnect);
}
} catch (Exception e) {
e.printStackTrace();
//Log.e("Response", "==> " + e.getMessage());
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError volleyError) {
// running on main thread-------
VolleyLog.d(TAG, "Error: " + volleyError.getMessage());
}
}) {
protected Map<String, String> getParams() {
HashMap<String, String> hashMapParams = new HashMap<String, String>();
hashMapParams.put("key", "value");
hashMapParams.put("key", "value");
hashMapParams.put("key", "value"));
hashMapParams.put("key", "value");
System.out.println("Hashmap:" + hashMapParams);
return hashMapParams;
}
};
AppController.getInstance().addToRequestQueue(request);
}

How to send a “multipart/form-data” POST in Android with Volley

Has anyone been able to accomplish sending a multipart/form-data POST in Android with Volley yet? I have had no success trying to upload an image/png using a POST request to our server and am curious if anyone has.
I believe the default way to do this would be to override public byte[] getPostBody() in the Request.java class and attach the File there with a blank Header key for the boundary. However, converting my file to a String for the Map<String, String> postParams and then having it encoded again seems obtuse and not really elegant. Also I've been unsuccessful in my attempts. This is really the only thing holding us back from switching to this library.
Anyway, all thoughts and answers are extremely appreciated. Thank you for your help.

I might be wrong on this but I think you need to implement your own com.android.volley.toolbox.HttpStack for this because the default ones (HurlStack if version > Gingerbread or HttpClientStack) don't deal with multipart/form-data.
Edit:
And indeed I was wrong. I was able to do it using MultipartEntity in Request like this:

private final File mFilePart;
private final String mStringPart;
public MultipartRequest(String url, Response.ErrorListener errorListener, Response.Listener<String> listener, File file, String stringPart)
{
super(Method.POST, url, errorListener);
mListener = listener;
mFilePart = file;
mStringPart = stringPart;
buildMultipartEntity();
}
private void buildMultipartEntity()
{
entity.addPart(FILE_PART_NAME, new FileBody(mFilePart));

It's pretty raw but I tried it with an image and a simple string and it works. The response is a placeholder, doesn't make much sense to return a Response String in this case. I had problems using apache httpmime to use MultipartEntity so I used this https://code.google.com/p/httpclientandroidlib/ don't know if there's a better way.
Hope it helps.
Edit
You can use httpmime without using httpclientandroidlib, the only dependency is httpcore.

As mentioned in the presentation at the I/O (about 4:05), Volley "is terrible" for large payloads. As I understand it that means not to use Volley for receiving/sending (big) files. Looking at the code it seems that it is not even designed to handle multipart form data (e.g. Request.java has getBodyContentType() with hardcoded "application/x-www-form-urlencoded"; HttpClientStack::createHttpRequest() can handle only byte[], etc...). Probably you will be able to create implementation that can handle multipart but If I were you I will just use HttpClient directly with MultipartEntity like:
HttpPost req = new HttpPost(composeTargetUrl());
MultipartEntity entity = new MultipartEntity();
entity.addPart(POST_IMAGE_VAR_NAME, new FileBody(toUpload));
try {
entity.addPart(POST_SESSION_VAR_NAME, new StringBody(uploadSessionId));
} catch (UnsupportedEncodingException e) {
throw new RuntimeException(e);
}
req.setEntity(entity);
You may need newer HttpClient (i.e. not the built-in) or even better, use Volley with newer HttpClient

A very simple approach for the dev who just want to send POST parameters in multipart request.
Make the following changes in class which extends Request.java
First define these constants :
String BOUNDARY = "s2retfgsGSRFsERFGHfgdfgw734yhFHW567TYHSrf4yarg"; //This the boundary which is used by the server to split the post parameters.
String MULTIPART_FORMDATA = "multipart/form-data;boundary=" + BOUNDARY;
Add a helper function to create a post body for you :
private String createPostBody(Map<String, String> params) {
StringBuilder sbPost = new StringBuilder();
if (params != null) {
for (String key : params.keySet()) {
if (params.get(key) != null) {
sbPost.append("\r\n" + "--" + BOUNDARY + "\r\n");
sbPost.append("Content-Disposition: form-data; name=\"" + key + "\"" + "\r\n\r\n");
sbPost.append(params.get(key).toString());
}
}
}
return sbPost.toString();
}
Override getBody() and getBodyContentType
public String getBodyContentType() {
return MULTIPART_FORMDATA;
}
public byte[] getBody() throws AuthFailureError {
return createPostBody(getParams()).getBytes();
}

First answer on SO.
I have encountered the same problem and found #alex 's code very helpful. I have made some simple modifications in order to pass in as many parameters as needed through HashMap, and have basically copied parseNetworkResponse() from StringRequest. I have searched online and so surprised to find out that such a common task is so rarely answered. Anyway, I wish the code could help:
public class MultipartRequest extends Request<String> {
private MultipartEntity entity = new MultipartEntity();
private static final String FILE_PART_NAME = "image";
private final Response.Listener<String> mListener;
private final File file;
private final HashMap<String, String> params;
public MultipartRequest(String url, Response.Listener<String> listener, Response.ErrorListener errorListener, File file, HashMap<String, String> params)
{
super(Method.POST, url, errorListener);
mListener = listener;
this.file = file;
this.params = params;
buildMultipartEntity();
}
private void buildMultipartEntity()
{
entity.addPart(FILE_PART_NAME, new FileBody(file));
try
{
for ( String key : params.keySet() ) {
entity.addPart(key, new StringBody(params.get(key)));
}
}
catch (UnsupportedEncodingException e)
{
VolleyLog.e("UnsupportedEncodingException");
}
}
#Override
public String getBodyContentType()
{
return entity.getContentType().getValue();
}
#Override
public byte[] getBody() throws AuthFailureError
{
ByteArrayOutputStream bos = new ByteArrayOutputStream();
try
{
entity.writeTo(bos);
}
catch (IOException e)
{
VolleyLog.e("IOException writing to ByteArrayOutputStream");
}
return bos.toByteArray();
}
/**
* copied from Android StringRequest class
*/
#Override
protected Response<String> parseNetworkResponse(NetworkResponse response) {
String parsed;
try {
parsed = new String(response.data, HttpHeaderParser.parseCharset(response.headers));
} catch (UnsupportedEncodingException e) {
parsed = new String(response.data);
}
return Response.success(parsed, HttpHeaderParser.parseCacheHeaders(response));
}
#Override
protected void deliverResponse(String response)
{
mListener.onResponse(response);
}
And you may use the class as following:
HashMap<String, String> params = new HashMap<String, String>();
params.put("type", "Some Param");
params.put("location", "Some Param");
params.put("contact", "Some Param");
MultipartRequest mr = new MultipartRequest(url, new Response.Listener<String>(){
#Override
public void onResponse(String response) {
Log.d("response", response);
}
}, new Response.ErrorListener(){
#Override
public void onErrorResponse(VolleyError error) {
Log.e("Volley Request Error", error.getLocalizedMessage());
}
}, f, params);
Volley.newRequestQueue(this).add(mr);

Another solution, very light with high performance with payload large:
Android Asynchronous Http Client library:
http://loopj.com/android-async-http/
private static AsyncHttpClient client = new AsyncHttpClient();
private void uploadFileExecute(File file) {
RequestParams params = new RequestParams();
try { params.put("photo", file); } catch (FileNotFoundException e) {}
client.post(getUrl(), params,
new AsyncHttpResponseHandler() {
public void onSuccess(String result) {
Log.d(TAG,"uploadFile response: "+result);
};
public void onFailure(Throwable arg0, String errorMsg) {
Log.d(TAG,"uploadFile ERROR!");
};
}
);
}

Here is Simple Solution And Complete Example for Uploading File Using Volley Android
1) Gradle Import
compile 'dev.dworks.libs:volleyplus:+'
2)Now Create a Class RequestManager
public class RequestManager {
private static RequestManager mRequestManager;
/**
* Queue which Manages the Network Requests :-)
*/
private static RequestQueue mRequestQueue;
// ImageLoader Instance
private RequestManager() {
}
public static RequestManager get(Context context) {
if (mRequestManager == null)
mRequestManager = new RequestManager();
return mRequestManager;
}
/**
* #param context application context
*/
public static RequestQueue getnstance(Context context) {
if (mRequestQueue == null) {
mRequestQueue = Volley.newRequestQueue(context);
}
return mRequestQueue;
}
}
3)Now Create a Class to handle Request for uploading File WebService
public class WebService {
private RequestQueue mRequestQueue;
private static WebService apiRequests = null;
public static WebService getInstance() {
if (apiRequests == null) {
apiRequests = new WebService();
return apiRequests;
}
return apiRequests;
}
public void updateProfile(Context context, String doc_name, String doc_type, String appliance_id, File file, Response.Listener<String> listener, Response.ErrorListener errorListener) {
SimpleMultiPartRequest request = new SimpleMultiPartRequest(Request.Method.POST, "YOUR URL HERE", listener, errorListener);
// request.setParams(data);
mRequestQueue = RequestManager.getnstance(context);
request.addMultipartParam("token", "text", "tdfysghfhsdfh");
request.addMultipartParam("parameter_1", "text", doc_name);
request.addMultipartParam("dparameter_2", "text", doc_type);
request.addMultipartParam("parameter_3", "text", appliance_id);
request.addFile("document_file", file.getPath());
request.setFixedStreamingMode(true);
mRequestQueue.add(request);
}
}
4) And Now Call The method Like This to Hit the service
public class Main2Activity extends AppCompatActivity implements Response.ErrorListener, Response.Listener<String>{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main2);
Button button=(Button)findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
uploadData();
}
});
}
private void uploadData() {
WebService.getInstance().updateProfile(getActivity(), "appl_doc", "appliance", "1", mChoosenFile, this, this);
}
#Override
public void onErrorResponse(VolleyError error) {
}
#Override
public void onResponse(String response) {
//Your response here
}
}

This is my way of doing it. It may be useful to others :
private void updateType(){
// Log.i(TAG,"updateType");
StringRequest request = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
// running on main thread-------
try {
JSONObject res = new JSONObject(response);
res.getString("result");
System.out.println("Response:" + res.getString("result"));
}else{
CustomTast ct=new CustomTast(context);
ct.showCustomAlert("Network/Server Disconnected",R.drawable.disconnect);
}
} catch (Exception e) {
e.printStackTrace();
//Log.e("Response", "==> " + e.getMessage());
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError volleyError) {
// running on main thread-------
VolleyLog.d(TAG, "Error: " + volleyError.getMessage());
}
}) {
protected Map<String, String> getParams() {
HashMap<String, String> hashMapParams = new HashMap<String, String>();
hashMapParams.put("key", "value");
hashMapParams.put("key", "value");
hashMapParams.put("key", "value"));
hashMapParams.put("key", "value");
System.out.println("Hashmap:" + hashMapParams);
return hashMapParams;
}
};
AppController.getInstance().addToRequestQueue(request);
}
