Constructor Detail

GeckoSession

public GeckoSession()

GeckoSession

public GeckoSession(@Nullable
                    GeckoSessionSettings settings)

Method Detail

getUserAgent

@AnyThread
 @NonNull
public GeckoResult<String> getUserAgent()

Get the current user agent string for this GeckoSession.

Returns:

a GeckoResult containing the UserAgent string

getDefaultUserAgent

@AnyThread
 @NonNull
public static String getDefaultUserAgent()

Get the default user agent for this GeckoView build. This method does not account for any override that might have been applied to the user agent string.

Returns:

the default user agent string

getPermissionDelegate

@UiThread
 @Nullable
public GeckoSession.PermissionDelegate getPermissionDelegate()

Get the current permission delegate for this GeckoSession.

Returns:

PermissionDelegate instance or null if using default delegate.

setPermissionDelegate

@UiThread
public void setPermissionDelegate(@Nullable
                                            GeckoSession.PermissionDelegate delegate)

Set the current permission delegate for this GeckoSession.

Parameters:

delegate - PermissionDelegate instance or null to use the default delegate.

isOpen

@AnyThread
public boolean isOpen()

Return whether this session is open.

Returns:

True if session is open.

See Also:

open(org.mozilla.geckoview.GeckoRuntime), close()

open

@UiThread
public void open(@NonNull
                           GeckoRuntime runtime)

Opens the session. Call this when you are ready to use a GeckoSession instance. The session is in a 'closed' state when first created. Opening it creates the underlying Gecko objects necessary to load a page, etc. Most GeckoSession methods only take affect on an open session, and are queued until the session is opened here. Opening a session is an asynchronous operation.

Parameters:

runtime - The Gecko runtime to attach this session to.

See Also:

close(), isOpen()

close

@UiThread
public void close()

Closes the session. This frees the underlying Gecko objects and unloads the current page. The session may be reopened later, but page state is not restored. Call this when you are finished using a GeckoSession instance.

See Also:

open(org.mozilla.geckoview.GeckoRuntime), isOpen()

getTextInput

@AnyThread
 @NonNull
public SessionTextInput getTextInput()

Get the SessionTextInput instance for this session. May be called on any thread.

Returns:

SessionTextInput instance.

getAccessibility

@UiThread
 @NonNull
public SessionAccessibility getAccessibility()

Get the SessionAccessibility instance for this session.

Returns:

SessionAccessibility instance.

Parameters:

request - Loader for this request.

See Also:

GeckoSession.Loader

loadUri

@AnyThread
public void loadUri(@NonNull
                               String uri)

Load the given URI. Convenience method for

     session.load(new Loader().uri(uri));
 

Parameters:

uri - The URI of the resource to load.

reload

@AnyThread
public void reload()

Reload the current URI.

reload

@AnyThread

Returns:

an instance of WebExtension.SessionController.

getFinder

@AnyThread
 @NonNull
public SessionFinder getFinder()

Get the SessionFinder instance for this session, to perform find-in-page operations.

Returns:

SessionFinder instance.

setActive

@AnyThread
public void setActive(boolean active)

Set this GeckoSession as active or inactive, which represents if the session is currently visible or not. Setting a GeckoSession to inactive will significantly reduce its memory footprint, but should only be done if the GeckoSession is not currently visible. Note that a session can be active (i.e. visible) but not focused. When a session is set inactive, it will flush the session state and trigger a `ProgressDelegate.onSessionStateChange` callback.

Parameters:

active - A boolean determining whether the GeckoSession is active.

See Also:

setFocused(boolean)

setFocused

@AnyThread
public void setFocused(boolean focused)

Move focus to this session or away from this session. Only one session has focus at a given time. Note that a session can be unfocused but still active (i.e. visible).

Parameters:

focused - True if the session should gain focus or false if the session should lose focus.

See Also:

setActive(boolean)
