| /** |
| * The {@link AutofillManager} provides ways for apps and custom views to integrate with the |
| * Autofill Framework lifecycle. |
| * |
| * <p>The autofill lifecycle starts with the creation of an autofill context associated with an |
| * activity context; the autofill context is created when one of the following methods is called for |
| * the first time in an activity context, and the current user has an enabled autofill service: |
| * |
| * <ul> |
| * <li>{@link #notifyViewEntered(View)} |
| * <li>{@link #notifyViewEntered(View, int, Rect)} |
| * <li>{@link #requestAutofill(View)} |
| * </ul> |
| * |
| * <p>Tipically, the context is automatically created when the first view of the activity is |
| * focused because {@code View.onFocusChanged()} indirectly calls |
| * {@link #notifyViewEntered(View)}. App developers can call {@link #requestAutofill(View)} to |
| * explicitly create it (for example, a custom view developer could offer a contextual menu action |
| * in a text-field view to let users manually request autofill). |
| * |
| * <p>After the context is created, the Android System creates a {@link android.view.ViewStructure} |
| * that represents the view hierarchy by calling |
| * {@link View#dispatchProvideAutofillStructure(android.view.ViewStructure, int)} in the root views |
| * of all application windows. By default, {@code dispatchProvideAutofillStructure()} results in |
| * subsequent calls to {@link View#onProvideAutofillStructure(android.view.ViewStructure, int)} and |
| * {@link View#onProvideAutofillVirtualStructure(android.view.ViewStructure, int)} for each view in |
| * the hierarchy. |
| * |
| * <p>The resulting {@link android.view.ViewStructure} is then passed to the autofill service, which |
| * parses it looking for views that can be autofilled. If the service finds such views, it returns |
| * a data structure to the Android System containing the following optional info: |
| * |
| * <ul> |
| * <li>Datasets used to autofill subsets of views in the activity. |
| * <li>Id of views that the service can save their values for future autofilling. |
| * </ul> |
| * |
| * <p>When the service returns datasets, the Android System displays an autofill dataset picker |
| * UI associated with the view, when the view is focused on and is part of a dataset. |
| * The application can be notified when the UI is shown by registering an |
| * {@link AutofillCallback} through {@link #registerCallback(AutofillCallback)}. When the user |
| * selects a dataset from the UI, all views present in the dataset are autofilled, through |
| * calls to {@link View#autofill(AutofillValue)} or {@link View#autofill(SparseArray)}. |
| * |
| * <p>When the service returns ids of savable views, the Android System keeps track of changes |
| * made to these views, so they can be used to determine if the autofill save UI is shown later. |
| * |
| * <p>The context is then finished when one of the following occurs: |
| * |
| * <ul> |
| * <li>{@link #commit()} is called or all savable views are gone. |
| * <li>{@link #cancel()} is called. |
| * </ul> |
| * |
| * <p>Finally, after the autofill context is commited (i.e., not cancelled), the Android System |
| * shows an autofill save UI if the value of savable views have changed. If the user selects the |
| * option to Save, the current value of the views is then sent to the autofill service. |
| * |
| * <p>It is safe to call into its methods from any thread. |
