Constants

ATTRIBUTION_BEHAVIOR_APP_SOURCE_AND_APP_TRIGGER

Added in 1.9.0
public static final int ATTRIBUTION_BEHAVIOR_APP_SOURCE_AND_APP_TRIGGER = 3

AttributionRegistrationBehavior that allows apps to register app sources and app triggers from WebView.

ATTRIBUTION_BEHAVIOR_APP_SOURCE_AND_WEB_TRIGGER

Added in 1.9.0
public static final int ATTRIBUTION_BEHAVIOR_APP_SOURCE_AND_WEB_TRIGGER = 1

AttributionRegistrationBehavior that allows apps to register app sources (sources associated with the app package name) and web triggers (triggers associated with the eTLD+1) from WebView.

This is the default behavior.

ATTRIBUTION_BEHAVIOR_DISABLED

Added in 1.9.0
public static final int ATTRIBUTION_BEHAVIOR_DISABLED = 0

AttributionRegistrationBehavior that disables source and trigger registration from WebView.

Note that the initial network call to the Attribution Source or Trigger URIs may still happen depending on the installed version of WebView, but any response is discarded and nothing will be stored on the device.

ATTRIBUTION_BEHAVIOR_WEB_SOURCE_AND_WEB_TRIGGER

Added in 1.9.0
public static final int ATTRIBUTION_BEHAVIOR_WEB_SOURCE_AND_WEB_TRIGGER = 2

AttributionRegistrationBehavior that allows apps to register web sources and web triggers from WebView.

This option should only be used after applying to use web sources.

DARK_STRATEGY_PREFER_WEB_THEME_OVER_USER_AGENT_DARKENING

Added in 1.3.0
Deprecated in 1.5.0
public static final int DARK_STRATEGY_PREFER_WEB_THEME_OVER_USER_AGENT_DARKENING = 2

In this mode WebView content will be darkened by a user agent unless web page supports dark theme. WebView determines whether web pages supports dark theme by the presence of color-scheme metadata containing "dark" value. For example, <meta name="color-scheme" content="dark light">. If the metadata is not presented WebView content will be darkened by a user agent and prefers-color-scheme media query will evaluate to light.

See specification for more information.

setForceDarkStrategy

DARK_STRATEGY_USER_AGENT_DARKENING_ONLY

Added in 1.3.0
Deprecated in 1.5.0
public static final int DARK_STRATEGY_USER_AGENT_DARKENING_ONLY = 0

In this mode WebView content will be darkened by a user agent and it will ignore the web page's dark theme if it exists. To avoid mixing two different darkening strategies, the prefers-color-scheme media query will evaluate to light.

See specification for more information.

See also
setForceDarkStrategy

DARK_STRATEGY_WEB_THEME_DARKENING_ONLY

Added in 1.3.0
Deprecated in 1.5.0
public static final int DARK_STRATEGY_WEB_THEME_DARKENING_ONLY = 1

In this mode WebView content will always be darkened using dark theme provided by web page. If web page does not provide dark theme support WebView content will be rendered with a default theme.

See specification for more information.

See also
setForceDarkStrategy

FORCE_DARK_AUTO

Added in 1.2.0
Deprecated in 1.5.0
public static final int FORCE_DARK_AUTO = 1

Enable force dark dependent on the state of the WebView parent view. If the WebView parent view is being automatically force darkened (@see android.view.View#setForceDarkAllowed), then WebView content will be rendered so as to emulate a dark theme. WebViews that are not attached to the view hierarchy will not be inverted.

If your app uses a dark theme, WebView will not be inverted. Similarly, if your app's theme inherits from a DayNight theme, WebView will not be inverted. In either of these cases, you should control the mode manually with FORCE_DARK_ON or FORCE_DARK_OFF.

See Force Dark documentation for more information.

setAlgorithmicDarkeningAllowed

Added in 1.5.0
@RequiresFeature(name = WebViewFeature.ALGORITHMIC_DARKENING, enforcement = "androidx.webkit.WebViewFeature#isFeatureSupported")
public static void setAlgorithmicDarkeningAllowed(
    @NonNull WebSettings settings,
    boolean allow
)

Control whether algorithmic darkening is allowed.

Note: This API and the behaviour described only apply to apps with targetSdkVersion ≥ TIRAMISU.

WebView always sets the media query prefers-color-scheme according to the app's theme attribute isLightTheme, i.e. prefers-color-scheme is light if isLightTheme is true or not specified, otherwise it is dark. This means that the web content's light or dark style will be applied automatically to match the app's theme if the content supports it.

Algorithmic darkening is disallowed by default.

If the app's theme is dark and it allows algorithmic darkening, WebView will attempt to darken web content using an algorithm, if the content doesn't define its own dark styles and doesn't explicitly disable darkening.

If Android is applying Force Dark to WebView then WebView will ignore the value of this setting and behave as if it were set to true.

The deprecated setForceDark and related API are no-ops in apps with targetSdkVersion ≥ TIRAMISU, but they still apply to apps with targetSdkVersion<TIRAMISU.

The below table summarizes how APIs work with different apps.

App Web content which uses prefers-color-scheme Web content which does not use prefers-color-scheme
App with isLightTheme True or not set Renders with the light theme defined by the content author. Renders with the default styling defined by the content author.
App with Android forceDark in effect Renders with the dark theme defined by the content author. Renders with the styling modified to dark colors by an algorithm if allowed by the content author.
App with isLightTheme False, targetSdkVersion<TIRAMISU, and has FORCE_DARK_AUTO Renders with the dark theme defined by the content author. Renders with the default styling defined by the content author.
App with isLightTheme False, targetSdkVersion ≥ TIRAMISU, and setAlgorithmicDarkening(false) Renders with the dark theme defined by the content author. Renders with the default styling defined by the content author.
App with isLightTheme False, targetSdkVersion ≥ TIRAMISU, and setAlgorithmicDarkening(true) Renders with the dark theme defined by the content author. Renders with the styling modified to dark colors by an algorithm if allowed by the content author.

To check if WebViewFeature.ALGORITHMIC_DARKENING is supported, isFeatureSupported should be called after WebView is created.

Parameters
@NonNull WebSettings settings

The WebSettings object to update.
boolean allow

allow algorithmic darkening or not.

By default, attribution sources will be registered as attributed to the app, while triggers are attributed to the loaded web content (ATTRIBUTION_BEHAVIOR_APP_SOURCE_AND_WEB_TRIGGER). Apps should only need to change this default if they have a specific semantic for how they use WebView. In particular, in-app browsers should follow the steps to apply to the allowlist for registering web sources and then set the ATTRIBUTION_BEHAVIOR_WEB_SOURCE_AND_WEB_TRIGGER behavior.

Parameters
@NonNull WebSettings settings

Settings retrieved from getSettings.
int behavior

New behavior to use.

    boolean enabled
)

This method controls if the relevant Cookie header will be added to the WebResourceRequest object passed to shouldInterceptRequest. It also enables the use of setCookies, which will otherwise be ignored.

Prefer using this method over calling CookieManager as part of intercepting requests if it is necessary to access cookies, as this approach will provide the correct set of cookies for the request.

This method should only be called if isFeatureSupported returns true for COOKIE_INTERCEPT.

Parameters
@NonNull WebSettings settings

Settings retrieved from getSettings.
boolean enabled

Whether cookie access during request intercept should be enabled.

setOffscreenPreRaster

Added in 1.1.0
@RequiresFeature(name = WebViewFeature.OFF_SCREEN_PRERASTER, enforcement = "androidx.webkit.WebViewFeature#isFeatureSupported")
public static void setOffscreenPreRaster(@NonNull WebSettings settings, boolean enabled)

Sets whether this WebView should raster tiles when it is offscreen but attached to a window. Turning this on can avoid rendering artifacts when animating an offscreen WebView on-screen. Offscreen WebViews in this mode use more memory. The default value is false. Please follow these guidelines to limit memory usage:

  • WebView size should be not be larger than the device screen size.
  • Limit use of this mode to a small number of WebViews. Use it for visible WebViews and WebViews about to be animated to visible.

This method should only be called if isFeatureSupported returns true for OFF_SCREEN_PRERASTER.

setPaymentRequestEnabled

Added in 1.14.0
@RequiresFeature(name = WebViewFeature.PAYMENT_REQUEST, enforcement = "androidx.webkit.WebViewFeature#isFeatureSupported")
public static void setPaymentRequestEnabled(@NonNull WebSettings settings, boolean enabled)

Enables PaymentRequest for the given WebSettings.

This feature requires adding the following snippet to the AndroidManifest.xml: 

  <queries>
      <intent>
          <action android:name="org.chromium.intent.action.PAY"/>
      </intent>
      <intent>
          <action android:name="org.chromium.intent.action.IS_READY_TO_PAY"/>
      </intent>
      <intent>
          <action android:name="org.chromium.intent.action.UPDATE_PAYMENT_DETAILS"/>
      </intent>
  </queries>

This is needed to allow WebView to query the device for the user's payment applications that are implemented according to the Android payment app developers guide.

  • The org.chromium.intent.action.PAY intent is necessary to let users make payments.
  • The org.chromium.intent.action.IS_READY_TO_PAY intent is necessary to let the merchant website know if the user is ready to pay.
  • The org.chromium.intent.action.UPDATE_PAYMENT_DETAILS intent is necessary for payment apps to support updating the price dynamically in response to the user selecting a different shipping address or option.

This method should only be called if isFeatureSupported returns true for PAYMENT_REQUEST.

Parameters
@NonNull WebSettings settings

Settings retrieved from getSettings.
boolean enabled

Whether PaymentRequestshould be enabled for this WebSettings.

setRequestedWithHeaderOriginAllowList

Added in 1.6.0
@RequiresFeature(name = WebViewFeature.REQUESTED_WITH_HEADER_ALLOW_LIST, enforcement = "androidx.webkit.WebViewFeature#isFeatureSupported")
public static void setRequestedWithHeaderOriginAllowList(
    @NonNull WebSettings settings,
    @NonNull Set<String> allowList
)

Set an allow-list of origins to receive the X-Requested-With HTTP header from the WebView owning the passed WebSettings.

Historically, this header was sent on all requests from WebView, containing the app package name of the embedding app. Depending on the version of installed WebView, this may no longer be the case, as the header was deprecated in late 2022, and its use discontinued.

Apps can use this method to restore the legacy behavior for servers that still rely on the deprecated header, but it should not be used to identify the WebView to first-party servers under the control of the app developer.

The format of the strings in the allow-list follows the origin rules of addWebMessageListener.

Parameters
@NonNull WebSettings settings

Settings retrieved from getSettings.
@NonNull Set<String> allowList

Set of origins to allow-list.
Throws
java.lang.IllegalArgumentException

if the allow-list contains a malformed origin.

setSafeBrowsingEnabled

Added in 1.1.0
@RequiresFeature(name = WebViewFeature.SAFE_BROWSING_ENABLE, enforcement = "androidx.webkit.WebViewFeature#isFeatureSupported")
public static void setSafeBrowsingEnabled(@NonNull WebSettings settings, boolean enabled)

Sets whether Safe Browsing is enabled. Safe Browsing allows WebView to protect against malware and phishing attacks by verifying the links.

Safe Browsing can be disabled for all WebViews using a manifest tag (read general Safe Browsing info). The manifest tag has a lower precedence than this API.

Safe Browsing is enabled by default for devices which support it.

This method should only be called if isFeatureSupported returns true for SAFE_BROWSING_ENABLE.

Parameters
@NonNull WebSettings settings

The WebSettings object to update.
boolean enabled

Whether Safe Browsing is enabled.

setSpeculativeLoadingStatus

Added in 1.12.0
@RequiresFeature(name = WebViewFeature.SPECULATIVE_LOADING, enforcement = "androidx.webkit.WebViewFeature#isFeatureSupported")
@WebSettingsCompat.ExperimentalSpeculativeLoading
public static void setSpeculativeLoadingStatus(
    @NonNull WebSettings settings,
    int speculativeLoadingStatus
)

Sets whether speculative loading status for this WebSettings. This API is experimental, it may change in the future without notice. Please use accordingly.

This method should only be called if isFeatureSupported returns true for SPECULATIVE_LOADING.

Parameters
@NonNull WebSettings settings

Settings retrieved from getSettings.
int speculativeLoadingStatus

The new status for the speculative loading. It will to be one of SpeculativeLoadingStatus

setUserAgentMetadata

Added in 1.9.0
@RequiresFeature(name = WebViewFeature.USER_AGENT_METADATA, enforcement = "androidx.webkit.WebViewFeature#isFeatureSupported")
public static void setUserAgentMetadata(
    @NonNull WebSettings settings,
    @NonNull UserAgentMetadata metadata
)

Sets the WebView's user-agent metadata to generate user-agent client hints.

UserAgentMetadata in WebView is used to populate user-agent client hints, they can provide the client’s branding and version information, the underlying operating system’s branding and major version, as well as details about the underlying device.

The user-agent string can be set with setUserAgentString, here are the details on how this API interacts it to generate user-agent client hints.

If the UserAgentMetadata is null and the overridden user-agent contains the system default user-agent, the system default value will be used.

If the UserAgentMetadata is null but the overridden user-agent doesn't contain the system default user-agent, only the low-entry user-agent client hints will be generated.

See this for more information about User-Agent Client Hints.

This method should only be called if isFeatureSupported returns true for USER_AGENT_METADATA.

Parameters
@NonNull WebSettings settings

Settings retrieved from getSettings.
