How to use Stetho with Volley?

Created a volley singleton class for my requests.This is my singleton class

public class VolleySingleton {

private static VolleySingleton instance;
private RequestQueue reQueue;

private VolleySingleton(Context context) {
reQueue = Volley.newRequestQueue(context,new OkHttpStack(new OkHttpClient()));
}

public static VolleySingleton getInstance(Context context) {
if(instance == null)
instance = new VolleySingleton(context);
return instance;
}

public RequestQueue getRequestQueue() {
return reQueue;
}

public <T> void addToRequestQueue(Request<T> request) {
request.setTag("app");
request.setShouldCache(false);
request.setRetryPolicy(new DefaultRetryPolicy(10000, DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
getRequestQueue().add(request);
}
}


And m using OKHTTP stack with my Volley implementation.This is my
OKHttp.class


public class OkHttpStack implements HttpStack {

private final OkHttpClient mClient;

public OkHttpStack(OkHttpClient client) {
this.mClient = client;
}

@Override
public HttpResponse performRequest(Request<?> request, Map<String, String> additionalHeaders)
throws IOException, AuthFailureError {

OkHttpClient client = mClient.clone();
int timeoutMs = request.getTimeoutMs();
client.setConnectTimeout(timeoutMs, TimeUnit.MILLISECONDS);
client.setReadTimeout(timeoutMs, TimeUnit.MILLISECONDS);
client.setWriteTimeout(timeoutMs, TimeUnit.MILLISECONDS);

com.squareup.okhttp.Request.Builder okHttpRequestBuilder = new com.squareup.okhttp.Request.Builder();
okHttpRequestBuilder.url(request.getUrl());

Map<String, String> headers = request.getHeaders();
for (final String name : headers.keySet()) {
okHttpRequestBuilder.addHeader(name, headers.get(name));
}
for (final String name : additionalHeaders.keySet()) {
okHttpRequestBuilder.addHeader(name, additionalHeaders.get(name));
}

setConnectionParametersForRequest(okHttpRequestBuilder, request);

com.squareup.okhttp.Request okHttpRequest = okHttpRequestBuilder.build();
Call okHttpCall = client.newCall(okHttpRequest);
Response okHttpResponse = okHttpCall.execute();

StatusLine responseStatus = new BasicStatusLine(parseProtocol(okHttpResponse.protocol()), okHttpResponse.code(), okHttpResponse.message());
BasicHttpResponse response = new BasicHttpResponse(responseStatus);
response.setEntity(entityFromOkHttpResponse(okHttpResponse));

Headers responseHeaders = okHttpResponse.headers();
for (int i = 0, len = responseHeaders.size(); i < len; i++) {
final String name = responseHeaders.name(i), value = responseHeaders.value(i);
if (name != null) {
response.addHeader(new BasicHeader(name, value));
}
}

return response;
}

private static HttpEntity entityFromOkHttpResponse(Response r) throws IOException {
BasicHttpEntity entity = new BasicHttpEntity();
ResponseBody body = r.body();

entity.setContent(body.byteStream());
entity.setContentLength(body.contentLength());
entity.setContentEncoding(r.header("Content-Encoding"));

if (body.contentType() != null) {
entity.setContentType(body.contentType().type());
}
return entity;
}

@SuppressWarnings("deprecation")
private static void setConnectionParametersForRequest(com.squareup.okhttp.Request.Builder builder, Request<?> request)
throws IOException, AuthFailureError {
switch (request.getMethod()) {
case Request.Method.DEPRECATED_GET_OR_POST:
// Ensure backwards compatibility. Volley assumes a request with a null body is a GET.
byte[] postBody = request.getPostBody();
if (postBody != null) {
builder.post(RequestBody.create(MediaType.parse(request.getPostBodyContentType()), postBody));
}
break;
case Request.Method.GET:
builder.get();
break;
case Request.Method.DELETE:
builder.delete();
break;
case Request.Method.POST:
builder.post(createRequestBody(request));
break;
case Request.Method.PUT:
builder.put(createRequestBody(request));
break;
case Request.Method.HEAD:
builder.head();
break;
case Request.Method.OPTIONS:
builder.method("OPTIONS", null);
break;
case Request.Method.TRACE:
builder.method("TRACE", null);
break;
case Request.Method.PATCH:
builder.patch(createRequestBody(request));
break;
default:
throw new IllegalStateException("Unknown method type.");
}
}

private static ProtocolVersion parseProtocol(final Protocol p) {
switch (p) {
case HTTP_1_0:
return new ProtocolVersion("HTTP", 1, 0);
case HTTP_1_1:
return new ProtocolVersion("HTTP", 1, 1);
case SPDY_3:
return new ProtocolVersion("SPDY", 3, 1);
case HTTP_2:
return new ProtocolVersion("HTTP", 2, 0);
}

throw new IllegalAccessError("Unkwown protocol");
}

private static RequestBody createRequestBody(Request r) throws AuthFailureError {
final byte[] body = r.getBody();
if (body == null) return null;

return RequestBody.create(MediaType.parse(r.getBodyContentType()), body);
}
}


I also intilized my Stetho in my application.class

Stetho.initialize(
Stetho.newInitializerBuilder(this)
.enableDumpapp(
Stetho.defaultDumperPluginsProvider(this))
.enableWebKitInspector(
Stetho.defaultInspectorModulesProvider(this))
.build());


The issue is when i debug i can't get the network calls made by my application in my browser.Not sure where i am going wrong!Help!

Answer

Updated OkHttpStack

and

Try this:

OkHttpClient client = new OkHttpClient();
client.networkInterceptors().add(new StethoInterceptor());
mRequestQueue = Volley.newRequestQueue(getApplicationContext(), new OkHttpStack(client));

with following dependencies:

compile 'com.facebook.stetho:stetho:1.1.1'
compile 'com.facebook.stetho:stetho-okhttp:1.1.1'
compile 'com.squareup.okhttp:okhttp:2.3.0'
