      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

      @UiThread public boolean isOpen()
      Return whether this session is open.
      Returns:
      True if session is open.
      See Also:

    • 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

      @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:

    • getTextInput

      @AnyThread @NonNull public SessionTextInput getTextInput()

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

      @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:

    • setPriorityHint

      Set this GeckoSession to high priority (PRIORITY_HIGH) whenever the app wants to signal to GeckoView that this GeckoSession is important to the app. GeckoView will keep the session state as long as possible. Set this to default priority (PRIORITY_DEFAULT) in any other case.

      Parameters:
      priorityHint - Priority of the geckosession, either high priority or default.

    • restoreState
