-/**
- * Handler responsible to updating the UI due to predicted apps changes. Operations:
- * 1) Pushes the predicted apps to all-apps. If all-apps is visible, waits until it becomes
- * invisible again before applying the changes. This ensures that the UI does not change abruptly
- * 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
