WebSettings

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

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

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).

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

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

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.

Gets whether the WebView supports the "viewport" HTML meta tag or will use a wide viewport.

Gets the WebView's user-agent string.

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 ICE_CREAM_SANDWICH_MR1 and below, and false for API level JELLY_BEAN and above.

Sets whether JavaScript running 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. See setAllowFileAccessFromFileURLs(boolean). To enable the most restrictive, and therefore secure policy, this setting should be disabled. Note 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 ICE_CREAM_SANDWICH_MR1 and below, and false for API level JELLY_BEAN and above.

Sets whether the Application Caches API should be enabled. The default is false. Note that in order for the Application Caches API to be enabled, a valid database path must also be supplied to setAppCachePath(String).

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.

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.

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.

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.

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.

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.

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

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.

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.

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

Sets the default font size. The default is 16.

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

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 should display on-screen zoom controls when using the built-in zoom mechanisms. See setBuiltInZoomControls(boolean). The default is true.

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

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

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

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.

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 ACCESS_COARSE_LOCATION, ACCESS_FINE_LOCATION;
• an application must provide an implementation of the onGeolocationPermissionsShowPrompt(String, GeolocationPermissions.Callback) callback to receive notifications that a page is requesting access to location via the JavaScript Geolocation API.

As an option, it is possible to store previous locations and web origin permissions in a database. See setGeolocationDatabasePath(String).

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

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

Sets the underlying layout algorithm. This will cause a relayout of the WebView. The default is NARROW_COLUMNS.

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

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.

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.

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

Sets the minimum font size. The default is 8.

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

Configures the WebView's behavior when a secure origin attempts to load a resource from an insecure origin. By default, apps that target KITKAT or below default to MIXED_CONTENT_ALWAYS_ALLOW. Apps targeting 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.

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

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 OFF.

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 NORMAL.

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

Sets whether the WebView should save form data. The default is true.

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

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

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

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

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 zoomIn() and zoomOut() methods. The default is true.

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

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

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.

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

Gets whether the WebView supports multiple windows.

Gets whether the WebView supports zoom.
