+/**
+ * TODO Enhance javadoc
+ *
+ * {@link ShortcutManager} manages shortcuts created by applications.
+ *
+ * <h3>Dynamic shortcuts and pinned shortcuts</h3>
+ *
+ * An application can publish shortcuts with {@link #setDynamicShortcuts(List)} and
+ * {@link #addDynamicShortcut(ShortcutInfo)}.  There can be at most
+ * {@link #getMaxDynamicShortcutCount()} number of dynamic shortcuts at a time from the same
+ * application.
+ * A dynamic shortcut can be deleted with {@link #deleteDynamicShortcut(String)}, and apps
+ * can also use {@link #deleteAllDynamicShortcuts()} to delete all dynamic shortcuts.
+ *
+ * <p>The shortcuts that are currently published by the above APIs are called "dynamic", because
+ * they can be removed by the creator application at any time.  The user may "pin" dynamic shortcuts
+ * on Launcher to make "pinned" shortcuts.  Pinned shortcuts <b>cannot</b> be removed by the creator
+ * app.  An application can obtain all pinned shortcuts from itself with
+ * {@link #getPinnedShortcuts()}.  Applications should keep the pinned shortcut information
+ * up-to-date using {@link #updateShortcuts(List)}.
+ *
+ * <p>The number of pinned shortcuts does not affect the number of dynamic shortcuts that can be
+ * published by an application at a time.
+ * No matter how many pinned shortcuts that Launcher has for an application, the
+ * application can still always publish {@link #getMaxDynamicShortcutCount()} number of dynamic
+ * shortcuts.
+ *
+ * <h3>Shortcut IDs</h3>
+ *
+ * Each shortcut must have an ID, which must be unique within each application.  When a shortcut is
+ * published, existing shortcuts with the same ID will be updated.  Note this may include a
+ * pinned shortcut.
+ *
+ * <h3>Rate limiting</h3>
+ *
+ * Calls to {@link #setDynamicShortcuts(List)}, {@link #addDynamicShortcut(ShortcutInfo)},
+ * and {@link #updateShortcuts(List)} will be
+ * rate-limited.  An application can call these methods at most
+ * {@link #getRemainingCallCount()} times until the rate-limiting counter is reset,
+ * which happens at a certain time every day.
+ *
+ * <p>An applications can use {@link #getRateLimitResetTime()} to get the next reset time.
+ *
+ * <h3>Backup and Restore</h3>
+ *
+ * Shortcuts will be backed up and restored across devices.  This means all information, including
+ * IDs, must be meaningful on a different device.
+ *
+ * TODO: Define a Broadcast to let apps update shortcuts on a restored device.
+ *
+ * <h3>APIs for launcher</h3>
+ *
+ * Launcher applications should use {@link LauncherApps} to get shortcuts that are published from
+ * applications.  Launcher applications can also pin shortcuts with
+ * {@link LauncherApps#pinShortcuts(String, List, UserHandle)}.

+ * Lets you define a gradient color, which is used inside
+ * {@link android.graphics.drawable.VectorDrawable}.
+ *
+ * {@link android.content.res.GradientColor}s are created from XML resource files defined in the
+ * "color" subdirectory directory of an application's resource directory.  The XML file contains
+ * a single "gradient" element with a number of attributes and elements inside.  For example:
+ * <pre>
+ * &lt;gradient xmlns:android="http://schemas.android.com/apk/res/android"&gt;
+ *   &lt;android:startColor="?android:attr/colorPrimary"/&gt;
+ *   &lt;android:endColor="?android:attr/colorControlActivated"/&gt;
+ *   &lt;.../&gt;
+ *   &lt;android:type="linear"/&gt;
+ * &lt;/gradient&gt;
+ * </pre>
+ *
+ * This can describe either a {@link android.graphics.LinearGradient},
+ * {@link android.graphics.RadialGradient}, or {@link android.graphics.SweepGradient}.
+ *
+ * Note that different attributes are relevant for different types of gradient.
+ * For example, android:gradientRadius is only applied to RadialGradient.
+ * androd:centerX and android:centerY are only applied to SweepGradient or RadialGradient.
+ * android:startX, android:startY, android:endX and android:endY are only applied to LinearGradient.
+ *
+ * Also note if any color "item" element is defined, then startColor, centerColor and endColor will
+ * be ignored.
