+ * in front of the user, even if an app launched and user pressed back button to return to the
+ * all-apps UI again.
+ * 2) Prefetch high-res icons for predicted apps. This ensures that we have the icons in memory
+ * even if all-apps is not opened as they are shown in search UI as well
+ * 3) Load instant app if it is not already in memory. As predictions are persisted on disk,
+ * instant app will not be in memory when launcher starts.
+ * 4) Maintains the current active client id (for the predictions) and all updates are performed on
+ * that client id.
