SaveInfo
extends Object
implements
Parcelable
java.lang.Object | |
↳ | android.service.autofill.SaveInfo |
Information used to indicate that an AutofillService
is interested on saving the
user-inputed data for future use, through a
AutofillService#onSaveRequest(SaveRequest, SaveCallback)
call.
A SaveInfo
is always associated with a FillResponse
, and it contains at least
two pieces of information:
AutofillId
) that need to be changed
to trigger a save request.
Typically, the SaveInfo
contains the same id
s as the Dataset
:
new FillResponse.Builder() .addDataset(new Dataset.Builder() .setValue(id1, AutofillValue.forText("homer"), createPresentation("homer")) // username .setValue(id2, AutofillValue.forText("D'OH!"), createPresentation("password for homer")) // password .build()) .setSaveInfo(new SaveInfo.Builder( SaveInfo.SAVE_DATA_TYPE_USERNAME | SaveInfo.SAVE_DATA_TYPE_PASSWORD, new AutofillId[] { id1, id2 }).build()) .build();
The save type flags are used to display the appropriate strings in the autofill save UI.
You can pass multiple values, but try to keep it short if possible. In the above example, just
SaveInfo.SAVE_DATA_TYPE_PASSWORD
would be enough.
There might be cases where the AutofillService
knows how to fill the screen,
but the user has no data for it. In that case, the FillResponse
should contain just the
SaveInfo
, but no Datasets
:
new FillResponse.Builder() .setSaveInfo(new SaveInfo.Builder(SaveInfo.SAVE_DATA_TYPE_PASSWORD, new AutofillId[] { id1, id2 }).build()) .build();
There might be cases where the user data in the AutofillService
is enough
to populate some fields but not all, and the service would still be interested on saving the
other fields. In that case, the service could set the
SaveInfo.Builder#setOptionalIds(AutofillId[])
as well:
new FillResponse.Builder() .addDataset(new Dataset.Builder() .setValue(id1, AutofillValue.forText("742 Evergreen Terrace"), createPresentation("742 Evergreen Terrace")) // street .setValue(id2, AutofillValue.forText("Springfield"), createPresentation("Springfield")) // city .build()) .setSaveInfo(new SaveInfo.Builder(SaveInfo.SAVE_DATA_TYPE_ADDRESS, new AutofillId[] { id1, id2 }) // street and city .setOptionalIds(new AutofillId[] { id3, id4 }) // state and zipcode .build()) .build();
The AutofillService#onSaveRequest(SaveRequest, SaveCallback)
can be triggered after
any of the following events:
Activity
finishes.
AutofillManager#commit()
.
SaveInfo
was created with the
FLAG_SAVE_ON_ALL_VIEWS_INVISIBLE
flag).
Builder#setTriggerId(AutofillId)
.
But it is only triggered when all conditions below are met:
SaveInfo
associated with the FillResponse
is not null
neither
has the FLAG_DELAY_SAVE
flag.
AutofillValue
s of all required views (as set by the requiredIds
passed
to the SaveInfo.Builder
constructor are not empty.
AutofillValue
of at least one view (be it required or optional) has changed
(i.e., it's neither the same value passed in a Dataset
, nor the initial value
presented in the view).
Dataset
in the last FillResponse
that completely matches the
screen state (i.e., all required and optional fields in the dataset have the same value as
the fields in the screen).
The service can also customize some aspects of the autofill save UI:
Builder#setDescription(CharSequence)
.
Builder#setCustomDescription(CustomDescription)
.
Builder#setNegativeAction(int, IntentSender)
.
Builder#setValidator(Validator)
.

public static final int FLAG_DELAY_SAVE
Postpone the autofill save UI.
If flag is set, the autofill save UI is not triggered when the
autofill context associated with the response associated with this SaveInfo
is
committed (with AutofillManager#commit()
). Instead, the FillContext
is delivered in future fill requests (with AutofillService.onFillRequest(android.service.autofill.FillRequest, android.os.CancellationSignal, android.service.autofill.FillCallback)
)
and save request (with AutofillService#onSaveRequest(SaveRequest, SaveCallback)
)
of an activity belonging to the same task.
This flag should be used when the service detects that the application uses multiple screens to implement an autofillable workflow (for example, one screen for the username field, another for password).
Constant Value: 4 (0x00000004)
public static final int FLAG_DONT_SAVE_ON_FINISH
By default, a save request is automatically triggered
once the Activity
finishes. If this flag is set, finishing the activity doesn't
trigger a save request.
This flag is typically used in conjunction with Builder#setTriggerId(AutofillId)
.
Constant Value: 2 (0x00000002)
public static final int FLAG_SAVE_ON_ALL_VIEWS_INVISIBLE
Usually, a save request is only automatically triggered
once the Activity
finishes. If this flag is set, it is triggered once all saved views
become invisible.
Constant Value: 1 (0x00000001)
public static final int NEGATIVE_BUTTON_STYLE_CANCEL
Style for the negative button of the save UI to cancel the save operation. In this case, the user tapping the negative button signals that they would prefer to not save the filled content.
Constant Value: 0 (0x00000000)
public static final int NEGATIVE_BUTTON_STYLE_NEVER
Style for the negative button of the save UI to never do the save operation. This means that the user does not need to save any data on this activity or application. Once the user tapping the negative button, the service should never trigger the save UI again. In addition to this, must consider providing restore options for the user.
Constant Value: 2 (0x00000002)
public static final int NEGATIVE_BUTTON_STYLE_REJECT
Style for the negative button of the save UI to reject the save operation. This could be useful if the user needs to opt-in your service and the save prompt is an advertisement of the potential value you can add to the user. In this case, the user tapping the negative button sends a strong signal that the feature may not be useful and you may consider some backoff strategy.
Constant Value: 1 (0x00000001)
public static final int POSITIVE_BUTTON_STYLE_CONTINUE
Style for the positive button of save UI to have next action before the save operation. This could be useful if the filled content contains sensitive personally identifiable information and then requires user confirmation or verification. In this case, the user tapping the positive button signals that they would complete the next required action to save the filled content.
Constant Value: 1 (0x00000001)
public static final int POSITIVE_BUTTON_STYLE_SAVE
Style for the positive button of save UI to request the save operation. In this case, the user tapping the positive button signals that they agrees to save the filled content.
Constant Value: 0 (0x00000000)
public static final int SAVE_DATA_TYPE_ADDRESS
Type used on when the FillResponse
represents a physical address (such as street,
city, state, etc).
Constant Value: 2 (0x00000002)
public static final int SAVE_DATA_TYPE_CREDIT_CARD
Type used when the FillResponse
represents a credit card.
Constant Value: 4 (0x00000004)
public static final int SAVE_DATA_TYPE_DEBIT_CARD
Type used when the FillResponse
represents a debit card.
Constant Value: 32 (0x00000020)
public static final int SAVE_DATA_TYPE_EMAIL_ADDRESS
Type used when the FillResponse
represents just an email address, without a password.
Constant Value: 16 (0x00000010)
public static final int SAVE_DATA_TYPE_GENERIC
Type used when the service can save the contents of a screen, but cannot describe what the content is for.
Constant Value: 0 (0x00000000)
public static final int SAVE_DATA_TYPE_GENERIC_CARD
Type used when the FillResponse
represents a card that does not a specified card or
cannot identify what the card is for.
Constant Value: 128 (0x00000080)
public static final int SAVE_DATA_TYPE_PASSWORD
Type used when the FillResponse
represents user credentials that have a password.
Constant Value: 1 (0x00000001)
public static final int SAVE_DATA_TYPE_PAYMENT_CARD
Type used when the FillResponse
represents a payment card except for credit and
debit cards.
Constant Value: 64 (0x00000040)
public static final int SAVE_DATA_TYPE_USERNAME
Type used when the FillResponse
represents just an username, without a password.
Constant Value: 8 (0x00000008)
public int describeContents ()
Describe the kinds of special objects contained in this Parcelable
instance's marshaled representation. For example, if the object will
include a file descriptor in the output of writeToParcel(android.os.Parcel, int)
,
the return value of this method must include the
CONTENTS_FILE_DESCRIPTOR
bit.
Returns | |
---|---|
int |
a bitmask indicating the set of special object types marshaled
by this Parcelable object instance.
Value is either 0 or CONTENTS_FILE_DESCRIPTOR |
public String toString ()
Returns a string representation of the object. In general, the
toString
method returns a string that
"textually represents" this object. The result should
be a concise but informative representation that is easy for a
person to read.
It is recommended that all subclasses override this method.
The toString
method for class Object
returns a string consisting of the name of the class of which the
object is an instance, the at-sign character `@
', and
the unsigned hexadecimal representation of the hash code of the
object. In other words, this method returns a string equal to the
value of:
getClass().getName() + '@' + Integer.toHexString(hashCode())
Returns | |
---|---|
String |
a string representation of the object. |
public void writeToParcel (Parcel parcel, int flags)
Flatten this object in to a Parcel.
Parameters | |
---|---|
parcel |
Parcel : The Parcel in which the object should be written. |
flags |
int : Additional flags about how the object should be written.
May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE .
Value is either 0 or a combination of Parcelable.PARCELABLE_WRITE_RETURN_VALUE , and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
