    <p>See this answer - <a href="https://stackoverflow.com/questions/16783177/set-expiration-policy-for-cache-using-googles-volley">Set expiration policy for cache using Google&#39;s Volley</a></p> <p>This means Volley decides whether to cache response or not based only on headers "Cache-Control" and then "Expires", "maxAge".</p> <p>What you could do is change this method <code>com.android.volley.toolbox.HttpHeaderParser.parseCacheHeaders(NetworkResponse response)</code> and ignore these headers, set <code>entry.softTtl</code> and <code>entry.ttl</code> fields to whatever value works for you and use your method in your request class. Here is an example:</p> <pre><code>/** * Extracts a {@link Cache.Entry} from a {@link NetworkResponse}. * Cache-control headers are ignored. SoftTtl == 3 mins, ttl == 24 hours. * @param response The network response to parse headers from * @return a cache entry for the given response, or null if the response is not cacheable. */ public static Cache.Entry parseIgnoreCacheHeaders(NetworkResponse response) { long now = System.currentTimeMillis(); Map&lt;String, String&gt; headers = response.headers; long serverDate = 0; String serverEtag = null; String headerValue; headerValue = headers.get("Date"); if (headerValue != null) { serverDate = HttpHeaderParser.parseDateAsEpoch(headerValue); } serverEtag = headers.get("ETag"); final long cacheHitButRefreshed = 3 * 60 * 1000; // in 3 minutes cache will be hit, but also refreshed on background final long cacheExpired = 24 * 60 * 60 * 1000; // in 24 hours this cache entry expires completely final long softExpire = now + cacheHitButRefreshed; final long ttl = now + cacheExpired; Cache.Entry entry = new Cache.Entry(); entry.data = response.data; entry.etag = serverEtag; entry.softTtl = softExpire; entry.ttl = ttl; entry.serverDate = serverDate; entry.responseHeaders = headers; return entry; } </code></pre> <p>Use this method in your Request class like this:</p> <pre><code>public class MyRequest extends com.android.volley.Request&lt;MyResponse&gt; { ... @Override protected Response&lt;MyResponse&gt; parseNetworkResponse(NetworkResponse response) { String jsonString = new String(response.data); MyResponse MyResponse = gson.fromJson(jsonString, MyResponse.class); return Response.success(MyResponse, HttpHeaderParser.parseIgnoreCacheHeaders(response)); } } </code></pre>

    1. COdoes this mean the cache will last beyond, onDestroy? So that the next time the app is created, it will fetch from the cache?

    2. COYes, cache is saved not only in memory but also on disk (see DiskBasedCache class for details). As a quick test, load some data, exit your app, switch off wifi or 3g and enter your app again. You can also specify cache size in mMaxCacheSizeInBytes field.

    3. COYes, it caches while i'm in the app, but when i quit the app and return into the app, fetching from cache returned null. Hence the question of whether it lives in between activity life cycles.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
