↳ | 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.

Used with setMixedContentMode(int)
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.
Used with setMixedContentMode(int)
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
.
Used with setMixedContentMode(int)
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.

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.
Enables or disables file access within WebView. File access is enabled by default. Note that this enables or disables file system access only. Assets and resources are still accessible using file:///android_asset and file:///android_res.
Sets whether JavaScript running in the context of a file scheme URL
should be allowed to access content from other file scheme URLs. To
enable the most restrictive, and therefore secure policy, this setting
should be disabled. Note that the value of this setting is ignored if
the value of getAllowUniversalAccessFromFileURLs()
is true.
Note too, that this setting affects only JavaScript access to file scheme
resources. Other access to such resources, for example, from image HTML
elements, is unaffected.
The default value is true for API level

In future quota will be managed automatically.
Sets the maximum size for the Application Cache content. The passed size
will be rounded to the nearest value that the database can support, so
this should be viewed as a guide, not a hard limit. Setting the
size to a value less than current database size does not cause the
database to be trimmed. The default size is MAX_VALUE
.
It is recommended to leave the maximum size set to the default value.
appCacheMaxSize | the maximum size in bytes |
---|
Sets the path to the Application Caches files. In order for the Application Caches API to be enabled, 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.
appCachePath | a String path to the directory containing Application Caches files. |
---|
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.
flag | whether the WebView should not load image resources from the network |
---|
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
reload()
is called.
If the application does not have the
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
INTERNET
permission, otherwise it is
true.
flag | whether the WebView should not load any resources from the network |
---|
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.
enabled | whether the WebView should use its built-in zoom mechanisms |
---|
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
.

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.

Sets the default zoom density of the page. This must be called from the UI
thread. The default is 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, setInitialScale(int)
and setUseWideViewPort(boolean)
can be used.

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.

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:
ACCESS_COARSE_LOCATION
,
ACCESS_FINE_LOCATION
;
onGeolocationPermissionsShowPrompt(String, GeolocationPermissions.Callback)
callback
to receive notifications that a page is requesting access to location
via the JavaScript Geolocation API.
