Using Apache HTTP Client with Android Volley + Hurl Stack

Android+Volley+Apache_Http_Client

Set up Apache with Volley 

DefaultHttpClient mDefaultHttpClient = new DefaultHttpClient();

			final ClientConnectionManager mClientConnectionManager = mDefaultHttpClient
					.getConnectionManager();
			final HttpParams mHttpParams = mDefaultHttpClient.getParams();
			final ThreadSafeClientConnManager mThreadSafeClientConnManager = new ThreadSafeClientConnManager(
					mHttpParams, mClientConnectionManager.getSchemeRegistry());

			mDefaultHttpClient = new DefaultHttpClient(
					mThreadSafeClientConnManager, mHttpParams);

			mDefaultHttpClient.setCookieStore(new BasicCookieStore());
			final HttpStack httpStack = new ExtHttpClientStack(
					mDefaultHttpClient); // using Apache Client

			this.mRequestQueue = Volley.newRequestQueue(
					mCtx.getApplicationContext(), httpStack);
					
					
------- create your own Hurl Stack
