    • 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
