Summary

Public constructors
`Builder(id: String, value: String, categoryId: String)` Creates a new builder for the user data used for field classification.

Public methods
UserData.Builder	`add(value: String, categoryId: String)` Adds a new value for user data.
UserData	`build()` Creates a new `UserData` instance.
UserData.Builder	`setFieldClassificationAlgorithm(name: String?, args: Bundle?)` Sets the default algorithm used for field classification.

Builder

Added in API level 28

Builder(
    id: String, 
    value: String, 
    categoryId: String)

Creates a new builder for the user data used for field classification.

The user data must contain at least one pair of value -> categoryId, and more pairs can be added through the add(java.lang.String,java.lang.String) method. For example:

new UserData.Builder("v1", "Bart Simpson", "name")
    .add("[email protected]", "email")
    .add("[email protected]", "email")
    .build();

Parameters
`id`	String: id used to identify the whole `UserData` object. This id is also returned by `AutofillManager.getUserDataId()`, which can be used to check if the `UserData` is up-to-date without fetching the whole object (through `AutofillManager.getUserData()`). This value cannot be `null`.
`value`	String: value of the user data. This value cannot be `null`.
`categoryId`	String: autofill field category. This value cannot be `null`.

Exceptions
`java.lang.IllegalArgumentException`	if any of the following occurs: `id` is empty `categoryId` is empty `value` is empty the length of `value` is lower than `UserData.getMinValueLength()` the length of `value` is higher than `UserData.getMaxValueLength()`

Public methods

add

Added in API level 28

fun add(
    value: String, 
    categoryId: String
): UserData.Builder

Adds a new value for user data.

Parameters
`value`	String: value of the user data. This value cannot be `null`.
`categoryId`	String: string used to identify the category the value is associated with. This value cannot be `null`.

Return
`UserData.Builder`	This value cannot be `null`.

Exceptions
`java.lang.IllegalStateException`	if: `build()` already called the `value` has already been added (Note: this restriction was lifted on Android `android.os.Build.VERSION_CODES#Q` and later) the number of unique `categoryId` values added so far is more than `UserData.getMaxCategoryCount()` the number of `values` added so far is is more than `UserData.getMaxUserDataSize()`
`java.lang.IllegalArgumentException`	if any of the following occurs: `id` is empty `categoryId` is empty `value` is empty the length of `value` is lower than `UserData.getMinValueLength()` the length of `value` is higher than `UserData.getMaxValueLength()`

build

Added in API level 28

fun build(): UserData

Creates a new UserData instance.

You should not interact with this builder once this method is called.

Return
`UserData`	The built dataset. This value cannot be `null`.

Exceptions
`java.lang.IllegalStateException`	if `build()` was already called.

setFieldClassificationAlgorithm

Added in API level 28

fun setFieldClassificationAlgorithm(
    name: String?, 
    args: Bundle?
): UserData.Builder

Sets the default algorithm used for field classification.

The currently available algorithms can be retrieve through AutofillManager.getAvailableFieldClassificationAlgorithms().

If not set, the default algorithm is used instead.

Parameters
`name`	String?: name of the algorithm or `null` to used default.
`args`	Bundle?: optional arguments to the algorithm. This value may be `null`.

Return
`UserData.Builder`	this builder This value cannot be `null`.

setFieldClassificationAlgorithmForCategory

Added in API level 29

fun setFieldClassificationAlgorithmForCategory(
    categoryId: String, 
    name: String?, 
    args: Bundle?
): UserData.Builder

Sets the algorithm used for field classification for the specified category.

The currently available algorithms can be retrieved through AutofillManager.getAvailableFieldClassificationAlgorithms().

If not set, the default algorithm is used instead.

Parameters
`categoryId`	String: autofill field category. This value cannot be `null`.
`name`	String?: name of the algorithm or `null` to used default.
`args`	Bundle?: optional arguments to the algorithm. This value may be `null`.

Return
`UserData.Builder`	this builder This value cannot be `null`.
