Hi,

if i try with API level = 15 i have this error:

1496-1510/com.package E/Volley﹕ [81] NetworkDispatcher.run: Unhandled exception java.lang.IllegalArgumentException: SSL context may not be null

I'm a beginner Android developer and I've barely been exposed to basic Java before. As a result, I'm finding it difficult to understand some of these examples.

For instance I'm reading through "android_volley_examples / src / com / github / volley_examples / Act_SimpleRequest.java" and trying to figure out what you're doing and what parts I can apply to my own code. Within the code, there's interactions with the UI, additional function calls, and new functions added further down the file. Figuring out these parts took a while, and figuring out more of the examples might take even longer.

Could you add some simple comments that summarize what's going on to some of your examples?

Hi,

i try to do simple JsonRequest with TLS/SSL and i write this code:

// Replace R.raw.clienttruststore with your trust keystore in this import server cert
InputStream trustKeyStore = getResources().openRawResource(R.raw.clienttruststore);

            // Replace R.raw.client with your client keystore
            InputStream keyStore = getResources().openRawResource(R.raw.client);

            RequestQueue queue = Volley
                    .newRequestQueue(Act_JsonRequest.this,
                            new ExtHttpClientStack(new SslHttpClient(trustKeyStore, "secret", 443, keyStore)));



            JsonObjectRequest myReq = new JsonObjectRequest(Method.GET, 
                                                    "https://192.168.1.4:8443/REST/app/generali/getA",null,
                                                    createMyReqSuccessListener(),
                                                    createMyReqErrorListener()){
                @Override
                public Map<String, String> getHeaders() throws AuthFailureError {
                    return createBasicAuthHeader("1", "2");
                }};
            queue.add(myReq);
}
    });

But not work, if i try with StringRequest work..but i want Json..you have any idea?

Hello:
Performance comparison of khandroid-httpclient-4.2.3.jar and ok-http.jar.
which one is better.

I was wondering if you could add a synchronous example to your set that uses RequestFuture and future.get(4, TimeUnit.SECONDS)
I followed the sample in the source code of the RequestFuture but future.get() blocks first and then times out with no result!

Thanks

don't work if the response is 204 with out content

gives the error

Hi,
Thanks for sharing such a good library. I used this in some android apps contains JSON Request and Response but now i am working on GraphQL so, it is different from JSON. Do you have chance to share some sample code how to implement volley using GraphQL

Hi,

I wanted to use your library to better understand how I can use SSL with Volley, the only problem is that I got exception on my 4.1.2 and 4.4.4 emulators. The real problem is that these exceptions aren't same on both devices : I receive a javax.net.ssl.SSLPeerUnverifiedException on the 4.1.2 (which seems quite logical because it's a self-signed certificate) but on the 4.4.4 it's quite critical because I'm receiving a java.net.UnknownHostException. I checked and the address is ok : it's yours!

int memClass = ((ActivityManager)context.getSystemService(Context.ACTIVITY_SERVICE)).getMemoryClass();
final int maxMemory = (int) (Runtime.getRuntime().maxMemory() / 1024);
Log.e("TAG","maxMemory:"+maxMemory+",memClass:"+memClass);

Your units are wrong?

Hi:
Could you write a file upload Request , Thank you !

Hi,

Trying to use new httpClient with PoolingHttpClientConnectionManager. Having so many issue.
Is there any way that I can get source of khandroid-httpclient-4.2.3.jar?

Regards,

Mike

Why does it return the exception? I've followed through your codes.

This is the CustomVolley(MyVolley).

package com.capstone.artink.app;

import android.content.Context;

import com.android.volley.RequestQueue;
import com.android.volley.toolbox.ImageLoader;
import com.android.volley.toolbox.Volley;
import com.capstone.artink.utils.LruBitmapCache;

public class CustomVolley{

    private static RequestQueue mRequestQueue;
    private static ImageLoader mImageLoader;

    private CustomVolley(){

    }

    static void init(Context context){
        mRequestQueue = Volley.newRequestQueue(context);
        mImageLoader = new ImageLoader(mRequestQueue, new LruBitmapCache());
    }

    public static RequestQueue getRequestQueue(){
        if(mRequestQueue != null){
            return mRequestQueue;
        }
        else { throw new IllegalStateException("RequestQueue Not Initialized"); }
    }

    public static ImageLoader getImageLoader(){
        if(mImageLoader != null){
            return mImageLoader;
        }

        else
        { throw new IllegalStateException("ImageLoader Not Initialized"); }
    }
}

This is the error on Dashboard.java line 101

RequestQueue queue = CustomVolley.getRequestQueue();

        final String user = username;
        final String type = usertype;

        JsonObjectRequest myRequest = new JsonObjectRequest(Request.Method.GET,
                Config.ENT_PROFILE_URL,
                null,
                RequestSuccessListener(),
                RequestFailedListener()) {

        };
        queue.add(myRequest);

I think I posted at the wrong file, it's supposed to be at Act_JsonRequest.java
