+/**
+ * Provides a mechanism for apps to query restrictions imposed by an entity that
+ * manages the user. Apps can also send permission requests to a local or remote
+ * device administrator to override default app-specific restrictions or any other
+ * operation that needs explicit authorization from the administrator.
+ * <p>
+ * Apps can expose a set of restrictions via a runtime receiver mechanism or via
+ * static meta data in the manifest.
+ * <p>
+ * If the user has an active restrictions provider, dynamic requests can be made in
+ * addition to the statically imposed restrictions. Dynamic requests are app-specific
+ * and can be expressed via a predefined set of templates.
+ * <p>
+ * The RestrictionsManager forwards the dynamic requests to the active
+ * restrictions provider. The restrictions provider can respond back to requests by calling
+ * {@link #notifyPermissionResponse(String, Bundle)}, when
+ * a response is received from the administrator of the device or user 
+ * The response is relayed back to the application via a protected broadcast,
+ * {@link #ACTION_PERMISSION_RESPONSE_RECEIVED}.
+ * <p>
+ * Static restrictions are specified by an XML file referenced by a meta-data attribute
+ * in the manifest. This enables applications as well as any web administration consoles
+ * to be able to read the template from the apk.
+ * <p>
+ * The syntax of the XML format is as follows:
+ * <pre>
+ * &lt;restrictions&gt;
+ *     &lt;restriction
+ *         android:key="&lt;key&gt;"
+ *         android:restrictionType="boolean|string|integer|multi-select|null"
+ *         ... /&gt;
+ *     &lt;restriction ... /&gt;
+ * &lt;/restrictions&gt;
+ * </pre>
+ * <p>
+ * The attributes for each restriction depend on the restriction type.

+/**
+ * A class that provides markup to a synthesis request to control aspects of speech.
+ * <p>
+ * Markup itself is a feature agnostic data format; the {@link Utterance} class defines the currently
+ * available set of features and should be used to construct instances of the Markup class.
+ * </p>
+ * <p>
+ * A marked up sentence is a tree. Each node has a type, an optional plain text, a set of
+ * parameters, and a list of children.
+ * The <b>type</b> defines what it contains, e.g. "text", "date", "measure", etc. A Markup node
+ * can be either a part of sentence (often a leaf node), or node altering some property of its
+ * children (node with children). The top level node has to be of type "utterance" and its children
+ * are synthesized in order.
+ * The <b>plain text</b> is optional except for the top level node. If the synthesis engine does not
+ * support Markup at all, it should use the plain text of the top level node. If an engine does not
+ * recognize or support a node type, it will try to use the plain text of that node if provided. If
+ * the plain text is null, it will synthesize its children in order.
+ * <b>Parameters</b> are key-value pairs specific to each node type. In case of a date node the
+ * parameters may be for example "month: 7" and "day: 10".
+ * The <b>nested markups</b> are children and can for example be used to nest semiotic classes (a
+ * measure may have a node of type "decimal" as its child) or to modify some property of its
+ * children. See "plain text" on how they are processed if the parent of the children is unknown to
+ * the engine.

+ * This class acts as a builder for {@link Markup} instances.
+ * <p>
+ * Each Utterance consists of a list of the semiotic classes ({@link Utterance.TtsCardinal} and
+ * {@link Utterance.TtsText}).
+ * <p>Each semiotic class can be supplied with morphosyntactic features
+ * (gender, animacy, multiplicity and case), it is up to the synthesis engine to use this
+ * information during synthesis.
+ * Examples where morphosyntactic features matter:
+ * <ul>
+ * <li>In French, the number one is verbalized differently based on the gender of the noun
+ * it modifies. "un homme" (one man) versus "une femme" (one woman).
+ * <li>In German the grammatical case (accusative, locative, etc) needs to be included to be
+ * verbalize correctly. In German you'd have the sentence "Sie haben 1 kilometer vor Ihnen" (You
+ * have 1 kilometer ahead of you), "1" in this case needs to become inflected to the accusative
+ * form ("einen") instead of the nominative form "ein".
+ * </p>
+ * <p>
+ * Utterance usage example:
+ * Markup m1 = new Utterance().append("The Eiffel Tower is")
+ *                            .append(new TtsCardinal(324))
+ *                            .append("meters tall.");
+ * Markup m2 = new Utterance().append("Sie haben")
+ *                            .append(new TtsCardinal(1).setGender(Utterance.GENDER_MALE)

+ * In the event that no weights are specified, the previous conventions are respected and
+ * columns and rows are taken as flexible if their views specify some form of alignment

- * A child's ability to stretch is inferred from the alignment properties of
- * its row and column groups (which are typically set by setting the
- * {@link LayoutParams#setGravity(int) gravity} property of the child's layout parameters).
- * If alignment was defined along a given axis then the component
- * is taken as <em>flexible</em> in that direction. If no alignment was set,
+ * The flexibility of a view is therefore influenced by its alignment which is,
+ * in turn, typically defined by setting the
+ * {@link LayoutParams#setGravity(int) gravity} property of the child's layout parameters.
+ * If either a weight or alignment were defined along a given axis then the component
+ * is taken as <em>flexible</em> in that direction. If no weight or alignment was set,
  * the component is instead assumed to be <em>inflexible</em>.

- * GridLayout does not provide support for the principle of <em>weight</em>, as defined in

- * <p>
- * Some common use-cases may nevertheless be accommodated as follows.
- * To place equal amounts of space around a component in a cell group;
- * use {@link #CENTER} alignment (or {@link LayoutParams#setGravity(int) gravity}).
- * For complete control over excess space distribution in a row or column;
- * use a {@link LinearLayout} subview to hold the components in the associated cell group.
- * When using either of these techniques, bear in mind that cell groups may be defined to overlap.

+    <p>Volley: Easy, Fast Networking for Android</p>
+</div>
+</a>
+
+
+<p>Volley is an HTTP library that makes networking for Android apps easier and most importantly,
+faster. Volley is available through the open
+<a href="https://android.googlesource.com/platform/frameworks/volley">AOSP</a> repository.</p>
+
+<p>Volley offers the following benefits:</p>
+
+<ul>
+
+<li>Automatic scheduling of network requests.</li>
+<li>Multiple concurrent network connections.</li>
+<li>Transparent disk and memory response caching with standard HTTP
+<a href=http://en.wikipedia.org/wiki/Cache_coherence">cache coherence</a>.</li>
+<li>Support for request prioritization.</li>
+<li>Cancellation request API. You can cancel a single request, or you can set blocks or
+scopes of requests to cancel.</li>
+<li>Ease of customization, for example, for retry and backoff.</li>
+<li>Strong ordering that makes it easy to correctly populate your UI with data fetched
+asynchronously from the network.</li>
+<li>Debugging and tracing tools.</li>
+
+</ul>
+
+<p>Volley excels at RPC-type operations used to populate a UI, such as fetching a page of
+search results as structured data. It integrates easily with any protocol and comes out of
+the box with support for raw strings, images, and JSON. By providing built-in support for
+the features you need, Volley frees you from writing boilerplate code and allows you to
+concentrate on the logic that is specific to your app.</p>
+<p>Volley is not suitable for large download or streaming operations, since Volley holds
+all responses in memory during parsing. For large download operations, consider using an
+alternative like {@link android.app.DownloadManager}.</p>
+
+<p>The core Volley library is developed in the open
+<a href="https://android.googlesource.com/platform/frameworks/volley">AOSP</a>
+repository at {@code frameworks/volley} and contains the main request dispatch pipeline
+as well as a set of commonly applicable utilities, available in the Volley "toolbox." The
+easiest way to add Volley to your project is to clone the Volley repository and set it as
+a library project:</p>
+
+<ol>
+<li>Git clone the repository by typing the following at the command line:
+
+<pre>
+git clone https://android.googlesource.com/platform/frameworks/volley
+</pre>
+</li>
+
+<li>Import the downloaded source into your app project as an Android library project
+(as described in <a href="{@docRoot}tools/projects/projects-eclipse.html">
+Managing Projects from Eclipse with ADT</a>, if you're using Eclipse) or make a
+<a href="{@docRoot}guide/faq/commontasks.html#addexternallibrary"><code>.jar</code> file</a>.</li>

+    <h3>Video</h3>
+    <p>Volley: Easy, Fast Networking for Android</p>
+</div>
+</a>
+
+<p>This lesson describes how to implement your own custom request types, for types that
+don't have out-of-the-box Volley support.</p>
+
+<h2 id="custom-request">Write a Custom Request</h2>
+
+Most requests have ready-to-use implementations in the toolbox; if your response is a string,
+image, or JSON, you probably won't need to implement a custom {@code Request}.</p>
+
+<p>For cases where you do need to implement a custom request, this is all you need
+to do:</p>
+
+<ul>
+
+<li>Extend the {@code Request&lt;T&gt;} class, where
+{@code &lt;T&gt;} represents the type of parsed response
+the request expects. So if your parsed response is a string, for example,
+create your custom request by extending {@code Request&lt;String&gt;}. See the Volley
+toolbox classes {@code StringRequest} and {@code ImageRequest} for examples of
+extending {@code Request&lt;T&gt;}.</li>
+
+<li>Implement the abstract methods {@code parseNetworkResponse()}
+and {@code deliverResponse()}, described in more detail below.</li>
+
+</ul>
+
+<h3>parseNetworkResponse</h3>
+
+<p>A {@code Response} encapsulates a parsed response for delivery, for a given type
+(such as string, image, or JSON). Here is a sample implementation of
+{@code parseNetworkResponse()}:</p>
+
+<pre>
+&#64;Override
+protected Response&lt;T&gt; parseNetworkResponse(
+        NetworkResponse response) {
+    try {
+        String json = new String(response.data,
+        HttpHeaderParser.parseCharset(response.headers));
+    return Response.success(gson.fromJson(json, clazz),
+    HttpHeaderParser.parseCacheHeaders(response));
+    }
+    // handle errors
+...
+}
+</pre>
+
+<p>Note the following:</p>
+
+<ul>
+<li>{@code parseNetworkResponse()} takes as its parameter a {@code NetworkResponse}, which
+contains the response payload as a byte[], HTTP status code, and response headers.</li>
+<li>Your implementation must return a {@code Response&lt;T&gt;}, which contains your typed
+response object and cache metadata or an error, such as in the case of a parse failure.</li>
+</ul>
+
+<p>If your protocol has non-standard cache semantics, you can build a {@code Cache.Entry}
+yourself, but most requests are fine with something like this:
+</p>
+<pre>return Response.success(myDecodedObject,
+        HttpHeaderParser.parseCacheHeaders(response));</pre>
+<p>
+Volley calls {@code parseNetworkResponse()} from a worker thread. This ensures that
+expensive parsing operations, such as decoding a JPEG into a Bitmap, don't block the UI
+thread.</p>
+
+<h3>deliverResponse</h3>
+
+<p>Volley calls you back on the main thread with the object you returned in
+{@code parseNetworkResponse()}. Most requests invoke a callback interface here,
+for example:
+</p>
+
+<pre>
+protected void deliverResponse(T response) {
+        listener.onResponse(response);
+</pre>
+
+<h3>Example: GsonRequest</h3>
+
+<p><a href="http://code.google.com/p/google-gson/">Gson</a> is a library for converting
+Java objects to and from JSON using reflection. You can define Java objects that have the
+same names as their corresponding JSON keys, pass Gson the class object, and Gson will fill
+in the fields for you. Here's a complete implementation of a Volley request that uses
+Gson for parsing:</p>
+
+<pre>
+public class GsonRequest&lt;T&gt; extends Request&lt;T&gt; {
+    private final Gson gson = new Gson();
+    private final Class&lt;T&gt; clazz;
+    private final Map&lt;String, String&gt; headers;
+    private final Listener&lt;T&gt; listener;
+
+    /**
+     * Make a GET request and return a parsed object from JSON.
+     *
+     * &#64;param url URL of the request to make
+     * &#64;param clazz Relevant class object, for Gson's reflection
+     * &#64;param headers Map of request headers
+     */
+    public GsonRequest(String url, Class&lt;T&gt; clazz, Map&lt;String, String&gt; headers,
+            Listener&lt;T&gt; listener, ErrorListener errorListener) {
+        super(Method.GET, url, errorListener);
+        this.clazz = clazz;
+        this.headers = headers;
+        this.listener = listener;
+    }
+
+    &#64;Override
+    public Map&lt;String, String&gt; getHeaders() throws AuthFailureError {
+        return headers != null ? headers : super.getHeaders();
+    }
+
+    &#64;Override
+    protected void deliverResponse(T response) {
+        listener.onResponse(response);
+    }
+
+    &#64;Override
+    protected Response&lt;T&gt; parseNetworkResponse(NetworkResponse response) {
+        try {
+            String json = new String(
+                    response.data,
+                    HttpHeaderParser.parseCharset(response.headers));
+            return Response.success(
+                    gson.fromJson(json, clazz),
+                    HttpHeaderParser.parseCacheHeaders(response));
+        } catch (UnsupportedEncodingException e) {
+            return Response.error(new ParseError(e));
+        } catch (JsonSyntaxException e) {
+            return Response.error(new ParseError(e));
+        }
+    }
+}
+</pre>
+
+<p>Volley provides ready-to-use {@code JsonArrayRequest} and {@code JsonArrayObject} classes
+if you prefer to take that approach. See <a href="request.html">
+Using Standard Request Types</a> for more information.</p>

+<p>
+This lesson describes how to use the common request types that Volley supports:</p>
+
+<ul>
+  <li>{@code StringRequest}. Specify a URL and receive a raw string in response. See
+  <a href="requestqueue.html">Setting Up a Request Queue</a> for an example.</li>
+  <li>{@code ImageRequest}. Specify a URL and receive an image in response.</li>
+  <li>{@code JsonObjectRequest} and {@code JsonArrayRequest} (both subclasses of
+  {@code JsonRequest}). Specify a URL and get a JSON object or array (respectively) in
+  response.</li>
+</ul>
+
+<p>If your expected response is one of these types, you probably won't have to implement a
+custom request. This lesson describes how to use these standard request types. For
+information on how to implement your own custom request, see <a href="requests-custom.html">
+Implementing a Custom Request</a>.</p>
+
+
+<h2 id="request-image">Request an Image</h2>
+
+<p>Volley offers the following classes for requesting images. These classes layer on top
+of each other to offer different levels of support for processing images:</p>
+
+<ul>
+  <li>{@code ImageRequest}&mdash;a canned request for getting an image at a given URL and
+  calling back with a decoded bitmap. It also provides convenience features like specifying
+  a size to resize to. Its main benefit is that Volley's thread scheduling ensures that
+  expensive image operations (decoding, resizing) automatically happen on a worker thread.</li>
+
+  <li>{@code ImageLoader}&mdash;a helper class that handles loading and caching images from
+  remote URLs. {@code ImageLoader} is a an orchestrator for large numbers of {@code ImageRequest}s,
+  for example when putting multiple thumbnails in a {@link android.widget.ListView}.
+  {@code ImageLoader} provides an in-memory cache to sit in front of the normal Volley
+  cache, which is important to prevent flickering. This makes it possible to achieve a
+  cache hit without blocking or deferring off the main thread, which is impossible when
+  using disk I/O. {@code ImageLoader} also does response coalescing, without which almost
+  every response handler would set a bitmap on a view and cause a layout pass per image.
+  Coalescing makes it possible to deliver multiple responses simultaneously, which improves
+  performance.</li>
+  <li>{@code NetworkImageView}&mdash;builds on {@code ImageLoader} and effectively replaces
+  {@link android.widget.ImageView} for situations where your image is being fetched over
+  the network via URL. {@code NetworkImageView} also manages canceling pending requests if
+  the view is detached from the hierarchy.</li>
+</ul>
+
+<h3>Use ImageRequest</h3>
+
+<p>Here is an example of using {@code ImageRequest}. It retrieves the image specified by
+the URL and displays it in the app. Note that this snippet interacts with the
+{@code RequestQueue} through a singleton class (see <a href="{@docRoot}
+training/volley/requestqueue.html#singleton">Setting Up a RequestQueue</a> for more discussion of
+this topic):</p>
+
+<pre>
+ImageView mImageView;
+String url = "http://i.imgur.com/7spzG.png";
+mImageView = (ImageView) findViewById(R.id.myImage);
+...
+
+// Retrieves an image specified by the URL, displays it in the UI.
+ImageRequest request = new ImageRequest(url,
+    new Response.Listener<Bitmap>() {
+        &#64;Override
+        public void onResponse(Bitmap bitmap) {
+            mImageView.setImageBitmap(bitmap);
+        }
+    }, 0, 0, null,
+    new Response.ErrorListener() {
+        public void onErrorResponse(VolleyError error) {
+            mImageView.setImageResource(R.drawable.image_load_error);
+        }
+    });
+// Access the RequestQueue through your singleton class.
+MySingleton.getInstance(this).addToRequestQueue(request);</pre>
+
+
+<h3>Use ImageLoader and NetworkImageView</h3>
+
+<p>You can use {@code ImageLoader} and {@code NetworkImageView} in concert to efficiently
+manage the display of multiple images, such as in a {@link android.widget.ListView}. In your
+layout XML file, you use {@code NetworkImageView} in much the same way you would use
+{@link android.widget.ImageView}, for example:</p>
+
+<pre>&lt;com.android.volley.toolbox.NetworkImageView
+        android:id=&quot;&#64;+id/networkImageView&quot;
+        android:layout_width=&quot;150dp&quot;
+        android:layout_height=&quot;170dp&quot;
+        android:layout_centerHorizontal=&quot;true&quot; /&gt;</pre>
+
+<p>You can use {@code ImageLoader} by itself to display an image, for example:</p>
+
+<pre>
+ImageLoader mImageLoader;
+ImageView mImageView;
+// The URL for the image that is being loaded.
+private static final String IMAGE_URL =
+    "http://developer.android.com/images/training/system-ui.png";
+...
+mImageView = (ImageView) findViewById(R.id.regularImageView);
+
+// Get the ImageLoader through your singleton class.
+mImageLoader = MySingleton.getInstance(this).getImageLoader();
+mImageLoader.get(IMAGE_URL, ImageLoader.getImageListener(mImageView,
+         R.drawable.def_image, R.drawable.err_image));
+</pre>
+
+<p>However, {@code NetworkImageView} can do this for you if all you're doing is populating
+an {@link android.widget.ImageView}. For example:</p>
+
+<pre>
+ImageLoader mImageLoader;
+NetworkImageView mNetworkImageView;
+private static final String IMAGE_URL =
+    "http://developer.android.com/images/training/system-ui.png";
+...
+
+// Get the NetworkImageView that will display the image.
+mNetworkImageView = (NetworkImageView) findViewById(R.id.networkImageView);
+
+// Get the ImageLoader through your singleton class.
+mImageLoader = MySingleton.getInstance(this).getImageLoader();
+
+// Set the URL of the image that should be loaded into this view, and
+// specify the ImageLoader that will be used to make the request.
+mNetworkImageView.setImageUrl(IMAGE_URL, mImageLoader);
+</pre>
+
+<p>The above snippets access the {@code RequestQueue} and the {@code ImageLoader}
+through a singleton class, as described in <a href="{@docRoot}training/volley/requestqueue.html#singleton">
+Setting Up a RequestQueue</a>. This approach ensures that your app creates single instances of
+these classes that last the lifetime of your app. The reason that this is important for
+{@code ImageLoader} (the helper class that handles loading and caching images) is that
+the main function of the in-memory cache is to allow for flickerless rotation. Using a
+singleton pattern allows the bitmap cache to outlive the activity. If instead you create the
+{@code ImageLoader} in an activity, the {@code ImageLoader} would be recreated along with
+the activity every time the user rotates the device. This would cause flickering.</p>
+
+<h4 id="lru-cache">Example LRU cache</h4>
+
+<p>The Volley toolbox provides a standard cache implementation via the
+{@code DiskBasedCache} class. This class caches files directly onto the hard disk in the
+specified directory. But to use {@code ImageLoader}, you should provide a custom
+in-memory LRU bitmap cache that implements the {@code ImageLoader.ImageCache} interface.
+You may want to set up your cache as a singleton; for more discussion of this topic, see
+<a href="{@docRoot}training/volley/requestqueue.html#singleton">
+Setting Up a RequestQueue</a>.</p>
+
+<p>Here is a sample implementation for an in-memory {@code LruBitmapCache} class.
+It extends the {@link android.support.v4.util.LruCache} class and implements the
+{@code ImageLoader.ImageCache} interface:</p>
+
+<pre>
+import android.graphics.Bitmap;
+import android.support.v4.util.LruCache;
+import android.util.DisplayMetrics;
+import com.android.volley.toolbox.ImageLoader.ImageCache;
+
+public class LruBitmapCache extends LruCache&lt;String, Bitmap&gt;
+        implements ImageCache {
+
+    public LruBitmapCache(int maxSize) {
+        super(maxSize);
+    }
+
+    public LruBitmapCache(Context ctx) {
+        this(getCacheSize(ctx));
+    }
+
+    &#64;Override
+    protected int sizeOf(String key, Bitmap value) {
+        return value.getRowBytes() * value.getHeight();
+    }
+
+    &#64;Override
+    public Bitmap getBitmap(String url) {
+        return get(url);
+    }
+
+    &#64;Override
+    public void putBitmap(String url, Bitmap bitmap) {
+        put(url, bitmap);
+    }
+
+    // Returns a cache size equal to approximately three screens worth of images.
+    public static int getCacheSize(Context ctx) {
+        final DisplayMetrics displayMetrics = ctx.getResources().
+                getDisplayMetrics();
+        final int screenWidth = displayMetrics.widthPixels;
+        final int screenHeight = displayMetrics.heightPixels;
+        // 4 bytes per pixel
+        final int screenBytes = screenWidth * screenHeight * 4;
+
+        return screenBytes * 3;
+    }
+}
+</pre>
+
+<p>Here is an example of how to instantiate an {@code ImageLoader} to use this
+cache:</p>
+
+<pre>
+RequestQueue mRequestQueue; // assume this exists.
+ImageLoader mImageLoader = new ImageLoader(mRequestQueue, new LruBitmapCache(
+            LruBitmapCache.getCacheSize()));
+</pre>
+
+
+<h2 id="request-json">Request JSON</h2>
+
+<p>Volley provides the following classes for JSON requests:</p>
+
+<ul>
+  <li>{@code JsonArrayRequest}&mdash;A request for retrieving a
+  {@link org.json.JSONArray}
+  response body at a given URL.</li>
+  <li>{@code JsonObjectRequest}&mdash;A request for retrieving a
+  {@link org.json.JSONObject}
+  response body at a given URL, allowing for an optional
+  {@link org.json.JSONObject}
+  to be passed in as part of the request body.</li>
+</ul>
+
+<p>Both classes are based on the common base class {@code JsonRequest}. You use them
+following the same basic pattern you use for other types of requests. For example, this
+snippet fetches a JSON feed and displays it as text in the UI:</p>
+
+<pre>
+TextView mTxtDisplay;
+ImageView mImageView;
+mTxtDisplay = (TextView) findViewById(R.id.txtDisplay);
+String url = "http://my-json-feed";
+
+JsonObjectRequest jsObjRequest = new JsonObjectRequest
+        (Request.Method.GET, url, null, new Response.Listener<JSONObject>() {
+
+    &#64;Override
+    public void onResponse(JSONObject response) {
+        mTxtDisplay.setText("Response: " + response.toString());
+    }
+}, new Response.ErrorListener() {
+
+    &#64;Override
+    public void onErrorResponse(VolleyError error) {
+        // TODO Auto-generated method stub
+
+    }
+});
+
+// Access the RequestQueue through your singleton class.
+MySingleton.getInstance(this).addToRequestQueue(jsObjRequest);
+</pre>
+
+For an example of implementing a custom JSON request based on
+<a href="http://code.google.com/p/google-gson/">Gson</a>, see the next lesson,
+<a href="request-custom.html">Implementing a Custom Request</a>.

+</div>
+</a>
+
+
+<p>The previous lesson showed you how to use the convenience method
+<code>Volley.newRequestQueue</code> to set up a {@code RequestQueue}, taking advantage of
+Volley's default behaviors. This lesson walks you through the explicit steps of creating a
+{@code RequestQueue}, to allow you to supply your own custom behavior.</p>
+
+<p>This lesson also describes the recommended practice of creating a {@code RequestQueue}
+as a singleton, which makes the {@code RequestQueue} last the lifetime of your app.</p>
+
+<h2 id="network">Set Up a Network and Cache</h2>
+
+<p>A {@code RequestQueue} needs two things to do its job: a network to perform transport
+of the requests, and a cache to handle caching. There are standard implementations of these
+available in the Volley toolbox: {@code DiskBasedCache} provides a one-file-per-response
+cache with an in-memory index, and {@code BasicNetwork} provides a network transport based
+on your choice of {@link android.net.http.AndroidHttpClient} or {@link java.net.HttpURLConnection}.</p>
+
+<p>{@code BasicNetwork} is Volley's default network implementation. A {@code BasicNetwork}
+must be initialized with the HTTP client your app is using to connect to the network.
+Typically this is {@link android.net.http.AndroidHttpClient} or
+{@link java.net.HttpURLConnection}:</p>
+<ul>
+<li>Use {@link android.net.http.AndroidHttpClient} for apps targeting Android API levels
+lower than API Level 9 (Gingerbread). Prior to Gingerbread, {@link java.net.HttpURLConnection}
+was unreliable. For more discussion of this topic, see
+<a href="http://android-developers.blogspot.com/2011/09/androids-http-clients.html">
+Android's HTTP Clients</a>. </li>
+
+<li>Use {@link java.net.HttpURLConnection} for apps targeting Android API Level 9
+(Gingerbread) and higher.</li>
+</ul>
+<p>To create an app that runs on all versions of Android, you can check the version of
+Android the device is running and choose the appropriate HTTP client, for example:</p>
+
+<pre>
+HttpStack stack;
+...
+// If the device is running a version >= Gingerbread...
+if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.GINGERBREAD) {
+    // ...use HttpURLConnection for stack.
+} else {
+    // ...use AndroidHttpClient for stack.
+}
+Network network = new BasicNetwork(stack);
+</pre>
+
+<p>This snippet shows you the steps involved in setting up a
+{@code RequestQueue}:</p>
+
+<pre>
+RequestQueue mRequestQueue;
+
+// Instantiate the cache
+Cache cache = new DiskBasedCache(getCacheDir(), 1024 * 1024); // 1MB cap
+
+// Set up the network to use HttpURLConnection as the HTTP client.
+Network network = new BasicNetwork(new HurlStack());
+
+// Instantiate the RequestQueue with the cache and network.
+mRequestQueue = new RequestQueue(cache, network);
+
+// Start the queue
+mRequestQueue.start();
+
+String url ="http://www.myurl.com";
+
+// Formulate the request and handle the response.
+StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
+        new Response.Listener&lt;String&gt;() {
+    &#64;Override
+    public void onResponse(String response) {
+        // Do something with the response
+    }
+},
+    new Response.ErrorListener() {
+        &#64;Override
+        public void onErrorResponse(VolleyError error) {
+            // Handle error
+    }
+});
+
+// Add the request to the RequestQueue.
+mRequestQueue.add(stringRequest);
+...
+</pre>
+
+<p>If you just need to make a one-time request and don't want to leave the thread pool
+around, you can create the {@code RequestQueue} wherever you need it and call {@code stop()} on the
+{@code RequestQueue} once your response or error has come back, using the
+{@code Volley.newRequestQueue()} method described in <a href="simple.html">Sending a Simple
+Request</a>. But the more common use case is to create the {@code RequestQueue} as a
+singleton to keep it running for the lifetime of your app, as described in the next section.</p>
+
+
+<h2 id="singleton">Use a Singleton Pattern</h2>
+
+<p>If your application makes constant use of the network, it's probably most efficient to
+set up a single instance of {@code RequestQueue} that will last the lifetime of your app.
+You can achieve this in various ways. The recommended approach is to implement a singleton
+class that encapsulates {@code RequestQueue} and other Volley
+functionality. Another approach is to subclass {@link android.app.Application} and set up the
+{@code RequestQueue} in {@link android.app.Application#onCreate Application.onCreate()}.
+But this approach is <a href="{@docRoot}reference/android/app/Application.html">
+discouraged</a>; a static singleton can provide the same functionality in a more modular
+way. </p>
+
+<p>A key concept is that the {@code RequestQueue} must be instantiated with the
+{@link android.app.Application} context, not an {@link android.app.Activity} context. This
+ensures that the {@code RequestQueue} will last for the lifetime of your app, instead of
+being recreated every time the activity is recreated (for example, when the user
+rotates the device).
+
+<p>Here is an example of a singleton class that provides {@code RequestQueue} and
+{@code ImageLoader} functionality:</p>
+
+<pre>private static MySingleton mInstance;
+    private RequestQueue mRequestQueue;
+    private ImageLoader mImageLoader;
+    private static Context mCtx;
+
+    private MySingleton(Context context) {
+        mCtx = context;
+        mRequestQueue = getRequestQueue();
+
+        mImageLoader = new ImageLoader(mRequestQueue,
+                new ImageLoader.ImageCache() {
+            private final LruCache&lt;String, Bitmap&gt;
+                    cache = new LruCache&lt;String, Bitmap&gt;(20);
+
+            &#64;Override
+            public Bitmap getBitmap(String url) {
+                return cache.get(url);
+            }
+
+            &#64;Override
+            public void putBitmap(String url, Bitmap bitmap) {
+                cache.put(url, bitmap);
+            }
+        });
+    }
+
+    public static synchronized MySingleton getInstance(Context context) {
+        if (mInstance == null) {
+            mInstance = new MySingleton(context);
+        }
+        return mInstance;
+    }
+
+    public RequestQueue getRequestQueue() {
+        if (mRequestQueue == null) {
+            // getApplicationContext() is key, it keeps you from leaking the
+            // Activity or BroadcastReceiver if someone passes one in.
+            mRequestQueue = Volley.newRequestQueue(mCtx.getApplicationContext());
+        }
+        return mRequestQueue;
+    }
+
+    public &lt;T&gt; void addToRequestQueue(Request&lt;T&gt; req) {
+        getRequestQueue().add(req);
+    }
+
+    public ImageLoader getImageLoader() {
+        return mImageLoader;
+    }
+}</pre>
+
+<p>Here are some examples of performing {@code RequestQueue} operations using the singleton
+class:</p>
+
+<pre>
+// Get a RequestQueue
+RequestQueue queue = MySingleton.getInstance(this.getApplicationContext()).
+    getRequestQueue();
+...
+
+// Add a request (in this example, called stringRequest) to your RequestQueue.
+MySingleton.getInstance(this).addToRequestQueue(stringRequest);

+</a>
+
+<p>At a high level, you use Volley by creating a {@code RequestQueue} and passing it
+{@code Request} objects. The {@code RequestQueue} manages worker threads for running the
+network operations, reading from and writing to the cache, and parsing responses. Requests
+do the parsing of raw responses and Volley takes care of dispatching the parsed response
+back to the main thread for delivery.</p>
+
+<p> This lesson describes how to send a request using the <code>Volley.newRequestQueue</code>
+convenience method, which sets up a {@code RequestQueue} for you.
+See the next lesson,
+<a href="requestqueue.html">Setting Up a RequestQueue</a>, for information on how to set
+up a {@code RequestQueue} yourself.</p>
+
+<p>This lesson also describes how to add a request to a {@code RequestQueue} and cancel a
+request.</p>
+
+<h2 id="manifest">Add the INTERNET Permission</h2>
+
+<p>To use Volley, you must add the
+{@link android.Manifest.permission#INTERNET android.permission.INTERNET} permission
+to your app's manifest. Without this, your app won't be able to connect to the network.</p>
+
+
+<h2 id="simple">Use newRequestQueue</h2>
+
+<p>Volley provides a convenience method <code>Volley.newRequestQueue</code> that sets up a
+{@code RequestQueue} for you, using default values, and starts the queue. For example:</p>
+
+<pre>
+final TextView mTextView = (TextView) findViewById(R.id.text);
+...
+
+// Instantiate the RequestQueue.
+RequestQueue queue = Volley.newRequestQueue(this);
+String url ="http://www.google.com";
+
+// Request a string response from the provided URL.
+StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
+            new Response.Listener<String>() {
+    &#64;Override
+    public void onResponse(String response) {
+        // Display the first 500 characters of the response string.
+        mTextView.setText("Response is: "+ response.substring(0,500));
+    }
+}, new Response.ErrorListener() {
+    &#64;Override
+    public void onErrorResponse(VolleyError error) {
+        mTextView.setText("That didn't work!");
+    }
+});
+// Add the request to the RequestQueue.
+queue.add(stringRequest);
+</pre>
+
+<p>Volley always delivers parsed responses on the main thread. Running on the main thread
+is convenient for populating UI controls with received data, as you can freely modify UI
+controls directly from your response handler, but it's especially critical to many of the
+important semantics provided by the library, particularly related to canceling requests.
+</p>
+
+<p>See <a href="requestqueue.html">Setting Up a RequestQueue</a> for a
+description of how to set up a {@code RequestQueue} yourself, instead of using the
+<code>Volley.newRequestQueue</code> convenience method.</p>
+
+<h2 id="send">Send a Request</h2>
+
+<p>To send a request, you simply construct one and add it to the {@code RequestQueue} with
+{@code add()}, as shown above. Once you add the request it moves through the pipeline,
+gets serviced, and has its raw response parsed and delivered.</p>
+
+<p>When you call {@code add()}, Volley runs one cache processing thread and a pool of
+network dispatch threads. When you add a request to the queue, it is picked up by the cache
+thread and triaged: if the request can be serviced from cache, the cached response is
+parsed on the cache thread and the parsed response is delivered on the main thread. If the
+request cannot be serviced from cache, it is placed on the network queue. The first
+available network thread takes the request from the queue, performs the HTTP transaction,
+parsse the response on the worker thread, writes the response to cache, and posts the parsed
+response back to the main thread for delivery.</p>
+
+<p>Note that expensive operations like blocking I/O and parsing/decoding are done on worker
+threads. You can add a request from any thread, but responses are always delivered on the
+main thread.</p>
+
+<p>Figure 1 illustrates the life of a request:</p>
+
+ <img src="{@docRoot}images/training/volley-request.png"
+  alt="system bars">
+<p class="img-caption"><strong>Figure 1.</strong> Life of a request.</p>
+
+
+<h2 id="cancel">Cancel a Request</h2>
+
+<p>To cancel a request, call {@code cancel()} on your {@code Request} object. Once cancelled,
+Volley guarantees that your response handler will never be called. What this means in
+practice is that you can cancel all of your pending requests in your activity's
+{@link android.app.Activity#onStop onStop()} method and you don't have to litter your
+response handlers with checks for {@code getActivity() == null},
+whether {@code onSaveInstanceState()} has been called already, or other defensive
+boilerplate.</p>
+
+<p>To take advantage of this behavior, you would typically have to
+track all in-flight requests in order to be able to cancel them at the
+appropriate time. There is an easier way: you can associate a tag object with each
+request. You can then use this tag to provide a scope of requests to cancel. For
+example, you can tag all of your requests with the {@link android.app.Activity} they
+are being made on behalf of, and call {@code requestQueue.cancelAll(this)} from
+{@link android.app.Activity#onStop onStop()}.
+Similarly, you could tag all thumbnail image requests in a
+{@link android.support.v4.view.ViewPager} tab with their respective tabs and cancel on swipe
+to make sure that the new tab isn't being held up by requests from another one.</p>
+
+<p>Here is an example that uses a string value for the tag:</p>
+
+<ol>
+<li>Define your tag and add it to your requests.
+<pre>
+public static final String TAG = "MyTag";
+StringRequest stringRequest; // Assume this exists.
+RequestQueue mRequestQueue;  // Assume this exists.
+
+// Set the tag on the request.
+stringRequest.setTag(TAG);
+
+// Add the request to the RequestQueue.
+mRequestQueue.add(stringRequest);</pre>
+</li>
+
+<li>In your activity's {@link android.app.Activity#onStop onStop()} method, cancel all requests that have this tag.
+<pre>
+&#64;Override
+protected void onStop () {
+    super.onStop();
+    if (mRequestQueue != null) {
+        mRequestQueue.cancelAll(TAG);
+    }
+}
+</pre></li></ol>
+
+<p>Take care when canceling requests. If you are depending on your response handler to
+advance a state or kick off another process, you need to account for this. Again, the
+response handler will not be called.
+</p>
