HttpAuthHandler

Kotlin |Java

public class HttpAuthHandler
extends Handler

java.lang.Object
↳	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(String, String) or cancel() to set the WebView's response to the request.

Summary

Public methods
`void`	`cancel()` Instructs the WebView to cancel the authentication request.
`void`	`proceed(String username, String password)` Instructs the WebView to proceed with the authentication with the given credentials.
`boolean`	`useHttpAuthUsernamePassword()` Gets whether the credentials stored for the current host (i.e.

Public methods

cancel

Added in API level 1

public void cancel ()

Instructs the WebView to cancel the authentication request.

Note: The host application must call this method on the host application's UI Thread.

proceed

Added in API level 1

public void proceed (String username, 
                String password)

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.

Note: The host application must call this method on the host application's UI Thread.

Parameters
`username`	`String`
`password`	`String`

useHttpAuthUsernamePassword

Added in API level 1

public boolean useHttpAuthUsernamePassword ()

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.

Note: The host application must call this method on the host application's UI Thread.

Returns
`boolean`	whether the credentials are suitable for use
