Public constructors

Builder

public Builder (CharSequence title, 
                CharSequence negativeButtonText)

Constructs a prompt builder with the given required options.

Parameters
`title`	`CharSequence`: The title to be displayed on the prompt.
`negativeButtonText`	`CharSequence`: The label for the negative button on the prompt.

Public methods

build

public Class2BiometricAuthPrompt build ()

Creates a new prompt with the specified options.

Returns
`Class2BiometricAuthPrompt`	An instance of `Class2BiometricAuthPrompt`.

setConfirmationRequired

public Class2BiometricAuthPrompt.Builder setConfirmationRequired (boolean confirmationRequired)

Sets a hint indicating whether the prompt should require explicit user confirmation after a passive biometric (e.g. iris or face) has been recognized but before AuthPromptCallback.onAuthenticationSucceeded(androidx.fragment.app.FragmentActivity, BiometricPrompt.AuthenticationResult) is called. Defaults to true.

Setting this option to false is generally only appropriate for frequent, low-value transactions, such as re-authenticating for a previously authorized app.

As a hint, the value of this option may be ignored by the system. For example, explicit confirmation may always be required if the user has toggled a system-wide setting to disallow pure passive authentication. This option will also be ignored on any device with an OS version prior to Android 10 (API 29).

Parameters
`confirmationRequired`	`boolean`: Whether the prompt should require explicit user confirmation for passive biometrics.

Returns
`Class2BiometricAuthPrompt.Builder`	This builder.

setDescription

public Class2BiometricAuthPrompt.Builder setDescription (CharSequence description)

Sets a description that should be displayed on the prompt. Defaults to null.

Parameters
`description`	`CharSequence`: A description for the prompt.

Returns
`Class2BiometricAuthPrompt.Builder`	This builder.

setSubtitle

public Class2BiometricAuthPrompt.Builder setSubtitle (CharSequence subtitle)

Sets a subtitle that should be displayed on the prompt. Defaults to null.

Parameters
`subtitle`	`CharSequence`: A subtitle for the prompt.

Returns
`Class2BiometricAuthPrompt.Builder`	This builder.
