AutofillManager

Kotlin |Java

public final class AutofillManager
extends Object

java.lang.Object
↳	android.view.autofill.AutofillManager

The AutofillManager class provides ways for apps and custom views to integrate with the Autofill Framework lifecycle.

To learn about using Autofill in your app, read the Autofill Framework guides.

Autofill lifecycle

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:

Typically, the context is automatically created when the first view of the activity is focused because View.onFocusChanged() indirectly calls notifyViewEntered(android.view.View). App developers can call requestAutofill(android.view.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).

After the context is created, the Android System creates a ViewStructure that represents the view hierarchy by calling View.dispatchProvideAutofillStructure(android.view.ViewStructure, int) in the root views of all application windows. By default, dispatchProvideAutofillStructure() results in subsequent calls to View.onProvideAutofillStructure(android.view.ViewStructure, int) and View.onProvideAutofillVirtualStructure(android.view.ViewStructure, int) for each view in the hierarchy.

The resulting 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:

Datasets used to autofill subsets of views in the activity.
Id of views that the service can save their values for future autofilling.

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 AutofillCallback through registerCallback(android.view.autofill.AutofillManager.AutofillCallback). When the user selects a dataset from the UI, all views present in the dataset are autofilled, through calls to View.autofill(AutofillValue) or View.autofill(SparseArray).

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.

The context is then finished when one of the following occurs:

commit() is called or all savable views are gone.
cancel() is called.

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.

Additional notes

It is safe to call AutofillManager methods from any thread.
Requires the PackageManager#FEATURE_AUTOFILL feature which can be detected using PackageManager.hasSystemFeature(String).

Constants

EXTRA_ASSIST_STRUCTURE

Added in API level 26

public static final String EXTRA_ASSIST_STRUCTURE

Intent extra: The assist structure which captures the filled screen.

Type: AssistStructure

Constant Value: "android.view.autofill.extra.ASSIST_STRUCTURE"

EXTRA_AUTHENTICATION_RESULT

Added in API level 26

public static final String EXTRA_AUTHENTICATION_RESULT

Intent extra: The result of an authentication operation. It is either a fully populated FillResponse or a fully populated Dataset if a response or a dataset is being authenticated respectively.

Type: FillResponse or a Dataset

Constant Value: "android.view.autofill.extra.AUTHENTICATION_RESULT"

EXTRA_AUTHENTICATION_RESULT_EPHEMERAL_DATASET

Added in API level 31

public static final String EXTRA_AUTHENTICATION_RESULT_EPHEMERAL_DATASET

Intent extra: The optional boolean extra field provided by the AutofillService accompanying the Dataset result of an authentication operation.

Before Build.VERSION_CODES.R, if the authentication result is a Dataset, it'll be used to autofill the fields, and also replace the existing dataset in the cached FillResponse. That means if the user clears the field values, the autofill suggestion will show up again with the new authenticated Dataset.

In Build.VERSION_CODES.R, we added an exception to this behavior that if the Dataset being authenticated is a pinned dataset (see InlinePresentation.isPinned()), the old Dataset will not be replaced.

In Build.VERSION_CODES.S, we added this boolean extra field to allow the AutofillService to explicitly specify whether the returned authenticated Dataset is ephemeral. An ephemeral Dataset will be used to autofill once and then thrown away. Therefore, when the boolean extra is set to true, the returned Dataset will not replace the old dataset from the existing FillResponse. When it's set to false, it will. When it's not set, the old dataset will be replaced, unless it is a pinned inline suggestion, which is consistent with the behavior in Build.VERSION_CODES.R.

Constant Value: "android.view.autofill.extra.AUTHENTICATION_RESULT_EPHEMERAL_DATASET"

EXTRA_CLIENT_STATE

Added in API level 26

public static final String EXTRA_CLIENT_STATE

Intent extra: The optional extras provided by the AutofillService.

For example, when the service responds to a FillCallback.onSuccess(android.service.autofill.FillResponse) with a FillResponse that requires authentication, the Intent that launches the service authentication will contain the Bundle set by FillResponse.Builder.setClientState(Bundle) on this extra.

On Android Build.VERSION_CODES.P and higher, the autofill service can also add this bundle to the Intent set as the result for an authentication request, so the bundle can be recovered later on SaveRequest.getClientState().

Type: Bundle

Constant Value: "android.view.autofill.extra.CLIENT_STATE"

EXTRA_INLINE_SUGGESTIONS_REQUEST

Added in API level 31

public static final String EXTRA_INLINE_SUGGESTIONS_REQUEST

Intent extra: the InlineSuggestionsRequest in the autofill request.

This is filled in the authentication intent so the AutofillService can use it to create the inline suggestion Dataset in the response, if the original autofill request contains the InlineSuggestionsRequest.

Constant Value: "android.view.autofill.extra.INLINE_SUGGESTIONS_REQUEST"

requestAutofill

Added in API level 26

public void requestAutofill (View view, 
                int virtualId, 
                Rect absBounds)

Explicitly requests a new autofill context for virtual views.

Normally, the autofill context is automatically started if necessary when notifyViewEntered(android.view.View, int, android.graphics.Rect) is called, but this method should be used in the cases where it must be explicitly started. For example, when the virtual view offers an AUTOFILL option on its contextual overflow menu, and the user selects it.

The virtual view boundaries must be absolute screen coordinates. For example, if the parent view uses bounds to draw the virtual view inside its Canvas, the absolute bounds could be calculated by:

   int offset[] = new int[2];
   getLocationOnScreen(offset);
   Rect absBounds = new Rect(bounds.left + offset[0],
       bounds.top + offset[1],
       bounds.right + offset[0], bounds.bottom + offset[1]);

Parameters
`view`	`View`: the virtual view parent. This value cannot be `null`.
`virtualId`	`int`: id identifying the virtual child inside the parent view.
`absBounds`	`Rect`: absolute boundaries of the virtual view in the screen. This value cannot be `null`.

requestAutofill

Added in API level 26

public void requestAutofill (View view)

Explicitly requests a new autofill context.

Normally, the autofill context is automatically started if necessary when notifyViewEntered(android.view.View) is called, but this method should be used in the cases where it must be explicitly started. For example, when the view offers an AUTOFILL option on its contextual overflow menu, and the user selects it.

Parameters
`view`	`View`: view requesting the new autofill context. This value cannot be `null`.

setUserData

Added in API level 28

public void setUserData (UserData userData)

Sets the UserData used for field classification

Note: This method should only be called by an app providing an autofill service, and it's ignored if the caller currently doesn't have an enabled autofill service for the user.

Parameters
`userData`	`UserData`: This value may be `null`.

showAutofillDialog

public boolean showAutofillDialog (View view, 
                int virtualId)

If autofill suggestions for a dialog-style UI are available for virtual view, shows a dialog allowing the user to select a suggestion and returns true.

The dialog may not be shown if the autofill service does not support it, if the autofill request has not returned a response yet, if the dialog was shown previously, or if the input method is already shown.

It is recommended apps to call this method the first time a user focuses on an autofill-able form, and to avoid showing the input method if the dialog is shown. If this method returns false, you should then instead show the input method (assuming that is how the view normally handles the focus event). If the user re-focuses on the view, you should not call this method again so as to not disrupt usage of the input method.

Parameters
`view`	`View`: the view hosting the virtual view hierarchy which is used to show autofill suggestions. This value cannot be `null`.
`virtualId`	`int`: id identifying the virtual view inside the host view.

Returns
`boolean`	`true` if the autofill dialog is being shown

showAutofillDialog

public boolean showAutofillDialog (View view)

If autofill suggestions for a dialog-style UI are available for view, shows a dialog allowing the user to select a suggestion and returns true.

Parameters
`view`	`View`: the view for which to show autofill suggestions. This is typically a view receiving a focus event. The autofill suggestions shown will include content for related views as well. This value cannot be `null`.

Returns
`boolean`	`true` if the autofill dialog is being shown

unregisterCallback

Added in API level 26

public void unregisterCallback (AutofillManager.AutofillCallback callback)

Unregisters a AutofillCallback to receive autofill events.

Parameters
`callback`	`AutofillManager.AutofillCallback`: callback to stop receiving events. This value may be `null`.
