Class Overview

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.

Summary

Nested Classes
enum WebSettings.LayoutAlgorithm Enum for controlling the layout of html. 
enum WebSettings.PluginState The plugin state effects how plugins are treated on a page. 
enum WebSettings.RenderPriority  
enum WebSettings.TextSize This enum was deprecated in API level 14. Use setTextZoom(int) and getTextZoom() instead.  
enum WebSettings.ZoomDensity Enum for specifying the WebView's desired density. 
Constants
int LOAD_CACHE_ELSE_NETWORK Use cached resources when they are available, even if they have expired.
int LOAD_CACHE_ONLY Don't use the network, load from the cache.
int LOAD_DEFAULT Default cache usage mode.
int LOAD_NORMAL This constant was deprecated in API level 17. This value is obsolete, as from API level HONEYCOMB and onwards it has the same effect as LOAD_DEFAULT.
int LOAD_NO_CACHE Don't use the cache, load from the network.
int MIXED_CONTENT_ALWAYS_ALLOW 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.
int MIXED_CONTENT_COMPATIBILITY_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.

Constants

public static final int LOAD_CACHE_ELSE_NETWORK

Added in API level 1

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)

public static final int LOAD_CACHE_ONLY

Added in API level 1

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

Constant Value: 3 (0x00000003)

public static final int LOAD_DEFAULT

Added in API level 1

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)

public static final int LOAD_NORMAL

Added in API level 1

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This value is obsolete, as from API level HONEYCOMB and onwards it has the same effect as LOAD_DEFAULT.

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

Constant Value: 0 (0x00000000)

public static final int LOAD_NO_CACHE

Added in API level 1

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

Constant Value: 2 (0x00000002)

public static final int MIXED_CONTENT_ALWAYS_ALLOW

Added in API level 21

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.

Constant Value: 0 (0x00000000)

public static final int MIXED_CONTENT_COMPATIBILITY_MODE

Added in API level 21

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.

Constant Value: 2 (0x00000002)

public static final int MIXED_CONTENT_NEVER_ALLOW

Added in API level 21

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.

Constant Value: 1 (0x00000001)

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.

Parameters
flag whether JavaScript running in the context of a file scheme URL should be allowed to access content from other file scheme URLs

public abstract void setAllowUniversalAccessFromFileURLs (boolean flag)

Added in API level 16

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.

Parameters
flag whether JavaScript running in the context of a file scheme URL should be allowed to access content from any origin

public abstract void setAppCacheEnabled (boolean flag)

Added in API level 7

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).

Parameters
flag true if the WebView should enable Application Caches

public abstract void setAppCacheMaxSize (long appCacheMaxSize)

Added in API level 7

This method was deprecated in API level 18.
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.

Parameters
appCacheMaxSize the maximum size in bytes

public abstract void setAppCachePath (String appCachePath)

Added in API level 7

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.

Parameters
appCachePath a String path to the directory containing Application Caches files.

public abstract void setBlockNetworkImage (boolean flag)

Added in API level 1

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 whether the WebView should not load image resources from the network

public abstract void setBlockNetworkLoads (boolean flag)

Added in API level 8

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.

Parameters
flag whether the WebView should not load any resources from the network
See Also

public abstract void setBuiltInZoomControls (boolean enabled)

Added in API level 3

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.

Parameters
enabled whether the WebView should use its built-in zoom mechanisms

public abstract void setCacheMode (int mode)

Added in API level 1

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 the mode to use

public abstract void setCursiveFontFamily (String font)

Added in API level 1

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

Parameters
font a font family name

public abstract void setDatabaseEnabled (boolean flag)

Added in API level 5

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 true if the WebView should use the database storage API

public abstract void setDatabasePath (String databasePath)

Added in API level 5

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 a path to the directory where databases should be saved.

public abstract void setDefaultFixedFontSize (int size)

Added in API level 1

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

Parameters
size a non-negative integer between 1 and 72. Any number outside the specified range will be pinned.

public abstract void setDefaultFontSize (int size)

Added in API level 1

Sets the default font size. The default is 16.

Parameters
size a non-negative integer between 1 and 72. Any number outside the specified range will be pinned.

public abstract void setDefaultTextEncodingName (String encoding)

Added in API level 1

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

Parameters

public abstract void setDefaultZoom (WebSettings.ZoomDensity zoom)

Added in API level 7

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 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.

Parameters
zoom the zoom density

public abstract void setDisplayZoomControls (boolean enabled)

Added in API level 7

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

Parameters
flag true if the WebView should use the DOM storage API

public abstract void setEnableSmoothTransition (boolean enable)

Added in API level 11

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.
