HttpAuthHandler

Kotlin |Java

open class HttpAuthHandler : Handler

kotlin.Any
↳	android.os.Handler
	↳	android.webkit.HttpAuthHandler

Represents a request for HTTP authentication. Instances of this class are created by the WebView and passed to WebViewClient#onReceivedHttpAuthRequest. The host application must call either proceed or cancel to set the WebView's response to the request.

Summary

Public methods
open Unit	`cancel()` Instructs the WebView to cancel the authentication request.
open Unit	`proceed(username: String!, password: String!)` Instructs the WebView to proceed with the authentication with the given credentials.
open Boolean	`useHttpAuthUsernamePassword()` Gets whether the credentials stored for the current host (i.e. the host for which

Inherited functions

From class Handler

`Handler`	`createAsync(looper: Looper)` Create a new Handler whose posted messages and runnables are not subject to synchronization barriers such as display vsync. Messages sent to an async handler are guaranteed to be ordered with respect to one another, but not necessarily with respect to messages from other Handlers.
`Handler`	`createAsync(looper: Looper, callback: Handler.Callback)` Create a new Handler whose posted messages and runnables are not subject to synchronization barriers such as display vsync. Messages sent to an async handler are guaranteed to be ordered with respect to one another, but not necessarily with respect to messages from other Handlers.
`Unit`	`dispatchMessage(msg: Message)` Handle system messages here.
`Unit`	`dump(pw: Printer, prefix: String)`
`Looper`	`getLooper()`
`String`	`getMessageName(message: Message)` Returns a string representing the name of the specified message. The default implementation will either return the class name of the message callback if any, or the hexadecimal representation of the message "what" field.
`Unit`	`handleMessage(msg: Message)` Subclasses must implement this to receive messages.
`Boolean`	`hasCallbacks(r: Runnable)` Check if there are any pending posts of messages with callback r in the message queue.
`Boolean`	`hasMessages(what: Int)` Check if there are any pending posts of messages with code 'what' in the message queue.
`Boolean`	`hasMessages(what: Int, object: Any?)` Check if there are any pending posts of messages with code 'what' and whose obj is 'object' in the message queue.
`Message`	`obtainMessage()` Returns a new `Message` from the global message pool. More efficient than creating and allocating new instances. The retrieved message has its handler set to this instance (Message.target == this). If you don't want that facility, just call Message.obtain() instead.
`Message`	`obtainMessage(what: Int)` Same as `obtainMessage()`, except that it also sets the what member of the returned Message.
`Message`	`obtainMessage(what: Int, obj: Any?)` Same as `obtainMessage()`, except that it also sets the what and obj members of the returned Message.
`Message`	`obtainMessage(what: Int, arg1: Int, arg2: Int)` Same as `obtainMessage()`, except that it also sets the what, arg1 and arg2 members of the returned Message.
`Message`	`obtainMessage(what: Int, arg1: Int, arg2: Int, obj: Any?)` Same as `obtainMessage()`, except that it also sets the what, obj, arg1,and arg2 values on the returned Message.
`Boolean`	`post(r: Runnable)` Causes the Runnable r to be added to the message queue. The runnable will be run on the thread to which this handler is attached.
`Boolean`	`postAtFrontOfQueue(r: Runnable)` Posts a message to an object that implements Runnable. Causes the Runnable r to executed on the next iteration through the message queue. The runnable will be run on the thread to which this handler is attached. This method is only for use in very special circumstances -- it can easily starve the message queue, cause ordering problems, or have other unexpected side-effects.
`Boolean`	`postAtTime(r: Runnable, uptimeMillis: Long)` Causes the Runnable r to be added to the message queue, to be run at a specific time given by uptimeMillis. The time-base is `android.os.SystemClock#uptimeMillis`. Time spent in deep sleep will add an additional delay to execution. The runnable will be run on the thread to which this handler is attached.
`Boolean`	`postAtTime(r: Runnable, token: Any?, uptimeMillis: Long)` Causes the Runnable r to be added to the message queue, to be run at a specific time given by uptimeMillis. The time-base is `android.os.SystemClock#uptimeMillis`. Time spent in deep sleep will add an additional delay to execution. The runnable will be run on the thread to which this handler is attached.
`Boolean`	`postDelayed(r: Runnable, delayMillis: Long)` Causes the Runnable r to be added to the message queue, to be run after the specified amount of time elapses. The runnable will be run on the thread to which this handler is attached. The time-base is `android.os.SystemClock#uptimeMillis`. Time spent in deep sleep will add an additional delay to execution.
`Boolean`	`postDelayed(r: Runnable, token: Any?, delayMillis: Long)` Causes the Runnable r to be added to the message queue, to be run after the specified amount of time elapses. The runnable will be run on the thread to which this handler is attached. The time-base is `android.os.SystemClock#uptimeMillis`. Time spent in deep sleep will add an additional delay to execution.
`Unit`	`removeCallbacks(r: Runnable)` Remove any pending posts of Runnable r that are in the message queue.
`Unit`	`removeCallbacks(r: Runnable, token: Any?)` Remove any pending posts of Runnable r with Object token that are in the message queue. If token is null, all callbacks will be removed.
`Unit`	`removeCallbacksAndMessages(token: Any?)` Remove any pending posts of callbacks and sent messages whose obj is token. If token is null, all callbacks and messages will be removed.
`Unit`	`removeMessages(what: Int)` Remove any pending posts of messages with code 'what' that are in the message queue.
`Unit`	`removeMessages(what: Int, object: Any?)` Remove any pending posts of messages with code 'what' and whose obj is 'object' that are in the message queue. If object is null, all messages will be removed.
`Boolean`	`sendEmptyMessage(what: Int)` Sends a Message containing only the what value.
`Boolean`	`sendEmptyMessageAtTime(what: Int, uptimeMillis: Long)` Sends a Message containing only the what value, to be delivered at a specific time.
`Boolean`	`sendEmptyMessageDelayed(what: Int, delayMillis: Long)` Sends a Message containing only the what value, to be delivered after the specified amount of time elapses.
`Boolean`	`sendMessage(msg: Message)` Pushes a message onto the end of the message queue after all pending messages before the current time. It will be received in `handleMessage`, in the thread attached to this handler.
`Boolean`	`sendMessageAtFrontOfQueue(msg: Message)` Enqueue a message at the front of the message queue, to be processed on the next iteration of the message loop. You will receive it in `handleMessage`, in the thread attached to this handler. This method is only for use in very special circumstances -- it can easily starve the message queue, cause ordering problems, or have other unexpected side-effects.
`Boolean`	`sendMessageAtTime(msg: Message, uptimeMillis: Long)` Enqueue a message into the message queue after all pending messages before the absolute time (in milliseconds) uptimeMillis. The time-base is `android.os.SystemClock#uptimeMillis`. Time spent in deep sleep will add an additional delay to execution. You will receive it in `handleMessage`, in the thread attached to this handler.
`Boolean`	`sendMessageDelayed(msg: Message, delayMillis: Long)` Enqueue a message into the message queue after all pending messages before (current time + delayMillis). You will receive it in `handleMessage`, in the thread attached to this handler.
`String`	`toString()`

Public methods

cancel

Added in API level 1

open fun cancel(): Unit

Instructs the WebView to cancel the authentication request.

proceed

Added in API level 1

open fun proceed(
    username: String!, 
    password: String!
): Unit

Instructs the WebView to proceed with the authentication with the given credentials. Credentials for use with this method can be retrieved from the WebView's store using WebView#getHttpAuthUsernamePassword.

useHttpAuthUsernamePassword

Added in API level 1

open fun useHttpAuthUsernamePassword(): Boolean

Gets whether the credentials stored for the current host (i.e. the host for which WebViewClient#onReceivedHttpAuthRequest was called) are suitable for use. Credentials are not suitable if they have previously been rejected by the server for the current request.

Return
`Boolean`	whether the credentials are suitable for use
