Android Volley - HttpResponseCache

Question

Android Volley - HttpResponseCache

I am creating an Android application that uses Volley to download images from the Internet.

I use LruCachewith Volley to cache bitmaps in memory, and that's fine. In addition, I would like Volley to use the built-in http-disk-based cache support using HttpResponseCache .

I implemented an example in this link, but I noticed that nothing is cached in HttpResponseCache(I checked by fetching the HitCount field in the cache object).

After sniffing in the Volley source code, I found that Volley manually removes the cache flag when opened URLConnection:

private URLConnection openConnection(URL url, Request<?> request) throws IOException {
        URLConnection connection = createConnection(url);

        int timeoutMs = request.getTimeoutMs();
        connection.setConnectTimeout(timeoutMs);
        connection.setReadTimeout(timeoutMs);
        connection.setUseCaches(false); // <-- Disables the caching
        connection.setDoInput(true);

        // use caller-provided custom SslSocketFactory, if any, for HTTPS
        if ("https".equals(url.getProtocol()) && mSslSocketFactory != null) {
            ((HttpsURLConnection)connection).setSSLSocketFactory(mSslSocketFactory);
        }

        return connection;
    }
