FORCE_DARK_AUTO

public static final int FORCE_DARK_AUTO

This constant was deprecated in API level 33.
refer to setForceDark(int)

Enable force dark dependent on the state of the WebView parent view. If the WebView parent view is being automatically force darkened (see: View.setForceDarkAllowed(boolean)), 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.

Constant Value: 1 (0x00000001)

FORCE_DARK_OFF

public static final int FORCE_DARK_OFF

This constant was deprecated in API level 33.
refer to setForceDark(int)

Disable force dark, irrespective of the force dark mode of the WebView parent. In this mode, WebView content will always be rendered as-is, regardless of whether native views are being automatically darkened.

Constant Value: 0 (0x00000000)

FORCE_DARK_ON

public static final int FORCE_DARK_ON

This constant was deprecated in API level 33.
refer to setForceDark(int)

Unconditionally enable force dark. In this mode WebView content will always be rendered so as to emulate a dark theme.

Constant Value: 2 (0x00000002)

LOAD_CACHE_ELSE_NETWORK

public static final int LOAD_CACHE_ELSE_NETWORK

Use cached resources when they are available, even if they have expired. Otherwise load resources from the network. Use with setCacheMode(int).

Constant Value: 1 (0x00000001)

LOAD_CACHE_ONLY

public static final int LOAD_CACHE_ONLY

Don't use the network, load from the cache. Use with setCacheMode(int).

Constant Value: 3 (0x00000003)

LOAD_DEFAULT

public static final int LOAD_DEFAULT

Default cache usage mode. If the navigation type doesn't impose any specific behavior, use cached resources when they are available and not expired, otherwise load resources from the network. Use with setCacheMode(int).

Constant Value: -1 (0xffffffff)

LOAD_NORMAL

public static final int LOAD_NORMAL

This constant was deprecated in API level 17.
This value is obsolete, as from API level Build.VERSION_CODES.HONEYCOMB and onwards it has the same effect as LOAD_DEFAULT.

Normal cache usage mode. Use with setCacheMode(int).

Constant Value: 0 (0x00000000)

LOAD_NO_CACHE

public static final int LOAD_NO_CACHE

Don't use the cache, load from the network. Use with setCacheMode(int).

Constant Value: 2 (0x00000002)

MENU_ITEM_NONE

public static final int MENU_ITEM_NONE

No menu items should be disabled.

Constant Value: 0 (0x00000000)

MENU_ITEM_PROCESS_TEXT

public static final int MENU_ITEM_PROCESS_TEXT

Disable all the action mode menu items for text processing. By default WebView searches for activities that are able to handle Intent.ACTION_PROCESS_TEXT and show them in the action mode menu. If this flag is set via setDisabledActionModeMenuItems(int), these menu items will be disabled.

Constant Value: 4 (0x00000004)

MENU_ITEM_SHARE

public static final int MENU_ITEM_SHARE

Disable menu item "Share".

Constant Value: 1 (0x00000001)

MENU_ITEM_WEB_SEARCH

public static final int MENU_ITEM_WEB_SEARCH

Disable menu item "Web Search".

Constant Value: 2 (0x00000002)

MIXED_CONTENT_ALWAYS_ALLOW

public static final int MIXED_CONTENT_ALWAYS_ALLOW

In this mode, the WebView will allow a secure origin to load content from any other origin, even if that origin is insecure. This is the least secure mode of operation for the WebView, and where possible apps should not set this mode.

Constant Value: 0 (0x00000000)

MIXED_CONTENT_COMPATIBILITY_MODE

public static final int MIXED_CONTENT_COMPATIBILITY_MODE

In this mode, the WebView will attempt to be compatible with the approach of a modern web browser with regard to mixed content. Some insecure content may be allowed to be loaded by a secure origin and other types of content will be blocked. The types of content are allowed or blocked may change release to release and are not explicitly defined. This mode is intended to be used by apps that are not in control of the content that they render but desire to operate in a reasonably secure environment. For highest security, apps are recommended to use MIXED_CONTENT_NEVER_ALLOW.

Constant Value: 2 (0x00000002)

MIXED_CONTENT_NEVER_ALLOW

public static final int MIXED_CONTENT_NEVER_ALLOW

In this mode, the WebView will not allow a secure origin to load content from an insecure origin. This is the preferred and most secure mode of operation for the WebView and apps are strongly advised to use this mode.

Constant Value: 1 (0x00000001)

isAlgorithmicDarkeningAllowed

public boolean isAlgorithmicDarkeningAllowed ()

Get if algorithmic darkening is allowed or not for this WebView. The default is false.

setAlgorithmicDarkeningAllowed

public void setAlgorithmicDarkeningAllowed (boolean allow)

Control whether algorithmic darkening is allowed.

Note: This API and the behaviour described only apply to apps with targetSdkVersion ≥ Build.VERSION_CODES.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(int) and related API are no-ops in apps with targetSdkVersion ≥ Build.VERSION_CODES.TIRAMISU, but they still apply to apps with targetSdkVersion < Build.VERSION_CODES.TIRAMISU.

The below table summarizes how APIs work with different apps.

setAllowContentAccess

public abstract void setAllowContentAccess (boolean allow)

Enables or disables content URL access within WebView. Content URL access allows WebView to load content from a content provider installed in the system. The default is enabled.

setAllowFileAccess

public abstract void setAllowFileAccess (boolean allow)

Enables or disables file access within WebView. Note that this enables or disables file system access only. Assets and resources are still accessible using file:///android_asset and file:///android_res.

Note: Apps should not open file:// URLs from any external source in WebView, don't enable this if your app accepts arbitrary URLs from external sources. It's recommended to always use androidx.webkit.WebViewAssetLoader to access files including assets and resources over http(s):// schemes, instead of file:// URLs. To prevent possible security issues targeting Build.VERSION_CODES.Q and earlier, you should explicitly set this value to false.

The default value is true for apps targeting Build.VERSION_CODES.Q and below, and false when targeting Build.VERSION_CODES.R and above.

setAllowFileAccessFromFileURLs

public abstract void setAllowFileAccessFromFileURLs (boolean flag)

This method was deprecated in API level 30.
This setting is not secure, please use androidx.webkit.WebViewAssetLoader to load file content securely.

Sets whether cross-origin requests in the context of a file scheme URL should be allowed to access content from other file scheme URLs. Note that some accesses such as image HTML elements don't follow same-origin rules and aren't affected by this setting.

Don't enable this setting if you open files that may be created or altered by external sources. Enabling this setting allows malicious scripts loaded in a file:// context to access arbitrary local files including WebView cookies and app private data.

Loading content via file:// URLs is generally discouraged. See the note in setAllowFileAccess(boolean).

Note that the value of this setting is ignored if the value of getAllowUniversalAccessFromFileURLs() is true. The default value is true for apps targeting Build.VERSION_CODES.ICE_CREAM_SANDWICH_MR1 and below, and false when targeting Build.VERSION_CODES.JELLY_BEAN and above. To prevent possible violation of same domain policy when targeting Build.VERSION_CODES.ICE_CREAM_SANDWICH_MR1 and earlier, you should explicitly set this value to false.

setAllowUniversalAccessFromFileURLs

public abstract void setAllowUniversalAccessFromFileURLs (boolean flag)

This method was deprecated in API level 30.
This setting is not secure, please use androidx.webkit.WebViewAssetLoader to load file content securely.

Sets whether cross-origin requests in the context of a file scheme URL should be allowed to access content from any origin. This includes access to content from other file scheme URLs or web contexts. Note that some access such as image HTML elements doesn't follow same-origin rules and isn't affected by this setting.

Don't enable this setting if you open files that may be created or altered by external sources. Enabling this setting allows malicious scripts loaded in a file:// context to launch cross-site scripting attacks, either accessing arbitrary local files including WebView cookies, app private data or even credentials used on arbitrary web sites.

Loading content via file:// URLs is generally discouraged. See the note in setAllowFileAccess(boolean).

The default value is true for apps targeting Build.VERSION_CODES.ICE_CREAM_SANDWICH_MR1 and below, and false when targeting Build.VERSION_CODES.JELLY_BEAN and above. To prevent possible violation of same domain policy when targeting Build.VERSION_CODES.ICE_CREAM_SANDWICH_MR1 and earlier, you should explicitly set this value to false.

setBlockNetworkImage

public abstract void setBlockNetworkImage (boolean flag)

Sets whether the WebView should not load image resources from the network (resources accessed via http and https URI schemes). Note that this method has no effect unless getLoadsImagesAutomatically() returns true. Also note that disabling all network loads using setBlockNetworkLoads(boolean) will also prevent network images from loading, even if this flag is set to false. When the value of this setting is changed from true to false, network images resources referenced by content currently displayed by the WebView are fetched automatically. The default is false.

setBlockNetworkLoads

public abstract void setBlockNetworkLoads (boolean flag)

Sets whether the WebView should not load resources from the network. Use setBlockNetworkImage(boolean) to only avoid loading image resources. Note that if the value of this setting is changed from true to false, network resources referenced by content currently displayed by the WebView are not fetched until WebView.reload() is called. If the application does not have the Manifest.permission.INTERNET permission, attempts to set a value of false will cause a SecurityException to be thrown. The default value is false if the application has the Manifest.permission.INTERNET permission, otherwise it is true.

setBuiltInZoomControls

public abstract void setBuiltInZoomControls (boolean enabled)

Sets whether the WebView should use its built-in zoom mechanisms. The built-in zoom mechanisms comprise on-screen zoom controls, which are displayed over the WebView's content, and the use of a pinch gesture to control zooming. Whether or not these on-screen controls are displayed can be set with setDisplayZoomControls(boolean). The default is false.

The built-in mechanisms are the only currently supported zoom mechanisms, so it is recommended that this setting is always enabled. However, on-screen zoom controls are deprecated in Android (see ZoomButtonsController) so it's recommended to disable setDisplayZoomControls(boolean).

setCacheMode

public abstract void setCacheMode (int mode)

Overrides the way the cache is used. The way the cache is used is based on the navigation type. For a normal page load, the cache is checked and content is re-validated as needed. When navigating back, content is not revalidated, instead the content is just retrieved from the cache. This method allows the client to override this behavior by specifying one of LOAD_DEFAULT, LOAD_CACHE_ELSE_NETWORK, LOAD_NO_CACHE or LOAD_CACHE_ONLY. The default value is LOAD_DEFAULT.

setCursiveFontFamily

public abstract void setCursiveFontFamily (String font)

Sets the cursive font family name. The default is "cursive".

setDatabaseEnabled

public abstract void setDatabaseEnabled (boolean flag)

This method was deprecated in API level 35.
WebSQL is deprecated and this method will become a no-op on all Android versions once support is removed in Chromium. See https://developer.chrome.com/blog/deprecating-web-sql for more information.

Sets whether the database storage API is enabled. The default value is false. See also setDatabasePath(String) for how to correctly set up the database storage API. This setting is global in effect, across all WebView instances in a process. Note you should only modify this setting prior to making any WebView page load within a given process, as the WebView implementation may ignore changes to this setting after that point.

setDatabasePath

public abstract void setDatabasePath (String databasePath)

This method was deprecated in API level 19.
Database paths are managed by the implementation and calling this method will have no effect.

Sets the path to where database storage API databases should be saved. In order for the database storage API to function correctly, this method must be called with a path to which the application can write. This method should only be called once: repeated calls are ignored.

setDefaultFixedFontSize

public abstract void setDefaultFixedFontSize (int size)

Sets the default fixed font size. The default is 16.

setDefaultFontSize

public abstract void setDefaultFontSize (int size)

Sets the default font size. The default is 16.

setDefaultTextEncodingName

public abstract void setDefaultTextEncodingName (String encoding)

Sets the default text encoding name to use when decoding html pages. The default is "UTF-8".

setDefaultZoom

public abstract void setDefaultZoom (WebSettings.ZoomDensity zoom)

This method was deprecated in API level 19.
This method is no longer supported, see the function documentation for recommended alternatives.

Sets the default zoom density of the page. This must be called from the UI thread. The default is ZoomDensity#MEDIUM. This setting is not recommended for use in new applications. If the WebView is utilized to display mobile-oriented pages, the desired effect can be achieved by adjusting 'width' and 'initial-scale' attributes of page's 'meta viewport' tag. For pages lacking the tag, WebView.setInitialScale(int) and setUseWideViewPort(boolean) can be used.

setDisabledActionModeMenuItems

public abstract void setDisabledActionModeMenuItems (int menuItems)

Disables the action mode menu items according to menuItems flag.

setDisplayZoomControls

public abstract void setDisplayZoomControls (boolean enabled)

Sets whether the WebView should display on-screen zoom controls when using the built-in zoom mechanisms. See setBuiltInZoomControls(boolean). The default is true. However, on-screen zoom controls are deprecated in Android (see ZoomButtonsController) so it's recommended to set this to false.

setDomStorageEnabled

public abstract void setDomStorageEnabled (boolean flag)

Sets whether the DOM storage API is enabled. The default value is false.

setEnableSmoothTransition

public abstract void setEnableSmoothTransition (boolean enable)

This method was deprecated in API level 17.
This method is now obsolete, and will become a no-op in future.

Sets whether the WebView will enable smooth transition while panning or zooming or while the window hosting the WebView does not have focus. If it is true, WebView will choose a solution to maximize the performance. e.g. the WebView's content may not be updated during the transition. If it is false, WebView will keep its fidelity. The default value is false.

setFantasyFontFamily

public abstract void setFantasyFontFamily (String font)

Sets the fantasy font family name. The default is "fantasy".

setFixedFontFamily

public abstract void setFixedFontFamily (String font)

Sets the fixed font family name. The default is "monospace".

setForceDark

public void setForceDark (int forceDark)

This method was deprecated in API level 33.
The "force dark" model previously implemented by WebView was complex and didn't interoperate well with current Web standards for prefers-color-scheme and color-scheme. In apps with targetSdkVersion ≥ Build.VERSION_CODES.TIRAMISU this API is a no-op and WebView will always use the dark style defined by web content authors if the app's theme is dark. To customize the behavior, refer to setAlgorithmicDarkeningAllowed(boolean).

Set the force dark mode for this WebView.

setGeolocationDatabasePath

public abstract void setGeolocationDatabasePath (String databasePath)

This method was deprecated in API level 24.
Geolocation database are managed by the implementation and calling this method will have no effect.

Sets the path where the Geolocation databases should be saved. In order for Geolocation permissions and cached positions to be persisted, this method must be called with a path to which the application can write.

setGeolocationEnabled

public abstract void setGeolocationEnabled (boolean flag)

Sets whether Geolocation is enabled. The default is true.

Please note that in order for the Geolocation API to be usable by a page in the WebView, the following requirements must be met:

• an application must have permission to access the device location, see Manifest.permission.ACCESS_COARSE_LOCATION, Manifest.permission.ACCESS_FINE_LOCATION;
• an application must provide an implementation of the WebChromeClient#onGeolocationPermissionsShowPrompt callback to receive notifications that a page is requesting access to location via the JavaScript Geolocation API.

setJavaScriptCanOpenWindowsAutomatically

public abstract void setJavaScriptCanOpenWindowsAutomatically (boolean flag)

Tells JavaScript to open windows automatically. This applies to the JavaScript function window.open(). The default is false.

setJavaScriptEnabled

public abstract void setJavaScriptEnabled (boolean flag)

Tells the WebView to enable JavaScript execution. The default is false.

setLayoutAlgorithm

public abstract void setLayoutAlgorithm (WebSettings.LayoutAlgorithm l)

Sets the underlying layout algorithm. This will cause a re-layout of the WebView. The default is LayoutAlgorithm#NARROW_COLUMNS.

setLightTouchEnabled

public abstract void setLightTouchEnabled (boolean enabled)

This method was deprecated in API level 18.
From Build.VERSION_CODES.JELLY_BEAN this setting is obsolete and has no effect.

Enables using light touches to make a selection and activate mouseovers.

setLoadWithOverviewMode

public abstract void setLoadWithOverviewMode (boolean overview)

Sets whether the WebView loads pages in overview mode, that is, zooms out the content to fit on screen by width. This setting is taken into account when the content width is greater than the width of the WebView control, for example, when getUseWideViewPort() is enabled. The default is false.

setLoadsImagesAutomatically

public abstract void setLoadsImagesAutomatically (boolean flag)

Sets whether the WebView should load image resources. Note that this method controls loading of all images, including those embedded using the data URI scheme. Use setBlockNetworkImage(boolean) to control loading only of images specified using network URI schemes. Note that if the value of this setting is changed from false to true, all images resources referenced by content currently displayed by the WebView are loaded automatically. The default is true.

setMediaPlaybackRequiresUserGesture

public abstract void setMediaPlaybackRequiresUserGesture (boolean require)

Sets whether the WebView requires a user gesture to play media. The default is true.

setMinimumFontSize

public abstract void setMinimumFontSize (int size)

Sets the minimum font size. The default is 8.

setMinimumLogicalFontSize

public abstract void setMinimumLogicalFontSize (int size)

Sets the minimum logical font size. The default is 8.

setMixedContentMode

public abstract void setMixedContentMode (int mode)

Configures the WebView's behavior when a secure origin attempts to load a resource from an insecure origin. By default, apps that target Build.VERSION_CODES.KITKAT or below default to MIXED_CONTENT_ALWAYS_ALLOW. Apps targeting Build.VERSION_CODES.LOLLIPOP default to MIXED_CONTENT_NEVER_ALLOW. The preferred and most secure mode of operation for the WebView is MIXED_CONTENT_NEVER_ALLOW and use of MIXED_CONTENT_ALWAYS_ALLOW is strongly discouraged.

setNeedInitialFocus

public abstract void setNeedInitialFocus (boolean flag)

Tells the WebView whether it needs to set a node to have focus when WebView#requestFocus(int, android.graphics.Rect) is called. The default value is true.

setOffscreenPreRaster

public abstract void setOffscreenPreRaster (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.

setPluginState

public abstract void setPluginState (WebSettings.PluginState state)

This method was deprecated in API level 18.
Plugins are not supported in API level Build.VERSION_CODES.KITKAT or later; enabling plugins is a no-op.

Tells the WebView to enable, disable, or have plugins on demand. On demand mode means that if a plugin exists that can handle the embedded content, a placeholder icon will be shown instead of the plugin. When the placeholder is clicked, the plugin will be enabled. The default is PluginState#OFF.

setRenderPriority

public abstract void setRenderPriority (WebSettings.RenderPriority priority)

This method was deprecated in API level 18.
It is not recommended to adjust thread priorities, and this will not be supported in future versions.

Sets the priority of the Render thread. Unlike the other settings, this one only needs to be called once per process. The default value is RenderPriority#NORMAL.

setSafeBrowsingEnabled

public abstract void setSafeBrowsingEnabled (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.

setSansSerifFontFamily

public abstract void setSansSerifFontFamily (String font)

Sets the sans-serif font family name. The default is "sans-serif".

setSaveFormData

public abstract void setSaveFormData (boolean save)

This method was deprecated in API level 26.
In Android O and afterwards, this function does not have any effect, the form data will be saved to platform's autofill service if applicable.

Sets whether the WebView should save form data. In Android O, the platform has implemented a fully functional Autofill feature to store form data. Therefore, the Webview form data save feature is disabled. Note that the feature will continue to be supported on older versions of Android as before.

setSavePassword

public abstract void setSavePassword (boolean save)

This method was deprecated in API level 18.
Saving passwords in WebView will not be supported in future versions.

Sets whether the WebView should save passwords. The default is true.

setSerifFontFamily

public abstract void setSerifFontFamily (String font)

Sets the serif font family name. The default is "sans-serif".

setStandardFontFamily

public abstract void setStandardFontFamily (String font)

Sets the standard font family name. The default is "sans-serif".

setSupportMultipleWindows

public abstract void setSupportMultipleWindows (boolean support)

Sets whether the WebView whether supports multiple windows. If set to true, WebChromeClient#onCreateWindow must be implemented by the host application. The default is false.

setSupportZoom

public abstract void setSupportZoom (boolean support)

Sets whether the WebView should support zooming using its on-screen zoom controls and gestures. The particular zoom mechanisms that should be used can be set with setBuiltInZoomControls(boolean). This setting does not affect zooming performed using the WebView#zoomIn() and WebView#zoomOut() methods. The default is true.

setTextSize

public void setTextSize (WebSettings.TextSize t)

This method was deprecated in API level 15.
Use setTextZoom(int) instead.

Sets the text size of the page. The default is TextSize#NORMAL.

setTextZoom

public abstract void setTextZoom (int textZoom)

Sets the text zoom of the page in percent. The default is 100.

setUseWideViewPort

public abstract void setUseWideViewPort (boolean use)

Sets whether the WebView should enable support for the "viewport" HTML meta tag or should use a wide viewport. When the value of the setting is false, the layout width is always set to the width of the WebView control in device-independent (CSS) pixels. When the value is true and the page contains the viewport meta tag, the value of the width specified in the tag is used. If the page does not contain the tag or does not provide a width, then a wide viewport will be used.

setUserAgentString

public abstract void setUserAgentString (String ua)

Sets the WebView's user-agent string. If the string is null or empty, the system default value will be used.

If the user-agent is overridden in this way, the values of the User-Agent Client Hints headers and navigator.userAgentData for this WebView could be changed.

See androidx.webkit.WebSettingsCompat #setUserAgentMetadata(WebSettings,UserAgentMetadata) for details.

Note that starting from Build.VERSION_CODES.KITKAT Android version, changing the user-agent while loading a web page causes WebView to initiate loading once again.

supportMultipleWindows

public abstract boolean supportMultipleWindows ()

Gets whether the WebView supports multiple windows.

supportZoom

public abstract boolean supportZoom ()

Gets whether the WebView supports zoom.
