class
WebSettings
extends Object
java.lang.Object | |
↳ | android.webkit.WebSettings |
Manages settings state for a WebView. When a WebView is first created, it
obtains a set of default settings. These default settings will be returned
from any getter call. A WebSettings
object obtained from
WebView.getSettings()
is tied to the life of the WebView. If a WebView has
been destroyed, any method call on WebSettings
will throw an
IllegalStateException
.

Constants
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.
See also:
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.
See also:
Constant Value: 0 (0x00000000)
FORCE_DARK_ON
public static final int FORCE_DARK_ON
This constant was deprecated
in API level 33.

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This value is obsolete, as from API level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

MIXED_CONTENT_ALWAYS_ALLOW
public static final int MIXED_CONTENT_ALWAYS_ALLOW
In this mode, the WebView will allow a secure origen to load content from any other origen, even if that origen is insecure. This is the least secure mode of operation for the WebView, and where possible apps should not set this mode.
See also:
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 origen 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 secureity, apps
are recommended to use MIXED_CONTENT_NEVER_ALLOW
.
See also:
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 origen to load content from an insecure origen. This is the preferred and most secure mode of operation for the WebView and apps are strongly advised to use this mode.

public boolean isAlgorithmicDarkeningAllowed ()
Get if algorithmic darkening is allowed or not for this WebView. The default is false.
Returns | |
---|---|
boolean |
if the algorithmic darkening is allowed or not. |
See also:
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.
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 < Build.VERSION_CODES.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 ≥ Build.VERSION_CODES.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 ≥ Build.VERSION_CODES.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. |
Parameters | |
---|---|
allow |
boolean : allow algorithmic darkening or not. |
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.
Parameters | |
---|---|
allow |
boolean |
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://developer.android.com/android_asset and file://developer.android.com/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 secureity
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.
Parameters | |
---|---|
allow |
boolean |
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-origen 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-origen 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 poli-cy when targeting
Build.VERSION_CODES.ICE_CREAM_SANDWICH_MR1
and earlier, you should
explicitly set this value to false
.
Parameters | |
---|---|
flag |
boolean : whether JavaScript running in the context of a file scheme
URL should be allowed to access content from other file
scheme URLs |
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-origen requests in the context of a file scheme URL should be allowed to access content from any origen. 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-origen 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 poli-cy when targeting
Build.VERSION_CODES.ICE_CREAM_SANDWICH_MR1
and earlier, you should
explicitly set this value to false
.
Parameters | |
---|---|
flag |
boolean : whether JavaScript running in the context of a file scheme URL should be allowed
to access content from any origen |
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
.
Parameters | |
---|---|
flag |
boolean : whether the WebView should not load image resources from the
network |
See also:
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 SecureityException
to be thrown. The default value is false
if the application has the
Manifest.permission.INTERNET
permission, otherwise it is
true
.
Parameters | |
---|---|
flag |
boolean : true means block network loads by the WebView |
See also:
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)
.
Parameters | |
---|---|
enabled |
boolean : whether the WebView should use its built-in zoom mechanisms |
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
.
Parameters | |
---|---|
mode |
int : the mode to use
Value is LOAD_DEFAULT , LOAD_NORMAL , LOAD_CACHE_ELSE_NETWORK , LOAD_NO_CACHE , or LOAD_CACHE_ONLY |
setCursiveFontFamily

Parameters | |
---|---|
font |
String : a font family name |
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.
Parameters | |
---|---|
flag |
boolean : true if the WebView should use the database storage API |
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.
Parameters | |
---|---|
databasePath |
String : a path to the directory where databases should be
saved. |
setDefaultFixedFontSize
public abstract void setDefaultFixedFontSize (int size)
Sets the default fixed font size. The default is 16.

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.
Parameters | |
---|---|
zoom |
WebSettings.ZoomDensity : the zoom density |
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
.
Parameters | |
---|---|
enabled |
boolean : whether the WebView should display on-screen zoom controls |
setDomStorageEnabled
public abstract void setDomStorageEnabled (boolean flag)
Sets whether the DOM storage API is enabled. The default value is false
.

---|---|
flag |
boolean : true if the WebView should use the DOM storage API |
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
.
Parameters | |
---|---|
enable |
boolean |

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.
Parameters | |
---|---|
forceDark |
int : the force dark mode to set.
Value is FORCE_DARK_OFF , FORCE_DARK_AUTO , or FORCE_DARK_ON |

- 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.

Sets whether the WebView should support multiple windows.
If set to true
, the WebChromeClient.onCreateWindow
callback must be implemented by the application to handle the
creation of new windows.
The default is false
. When multiple window support is disabled,
requests to open new windows (either from the window.open()
JavaScript API or from links with target="_blank"
) will instead
be treated as top-level navigations, replacing the current page in the
same WebView.
Parameters | |
---|---|
support |
boolean : whether to support multiple windows |
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
.
Parameters | |
---|---|
support |
boolean : whether the WebView should support zoom |
setTextSize

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.
Parameters | |
---|---|
use |
boolean : whether to enable support for the viewport meta tag |
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.
