      @UiThread default void onContextMenu(@NonNull GeckoSession session, int screenX, int screenY, @NonNull GeckoSession.ContentDelegate.ContextElement element)

    • onExternalResponse

      @UiThread default void onExternalResponse(@NonNull GeckoSession session, @NonNull WebResponse response)
      This is fired when there is a response that cannot be handled by Gecko (e.g., a download).
      Parameters:
      session - the GeckoSession that received the external response.
      response - the external WebResponse.

    • onCrash

      @UiThread default void onCrash(@NonNull GeckoSession session)
      The content process hosting this GeckoSession has crashed. The GeckoSession is now closed and unusable. You may call GeckoSession.open(GeckoRuntime) to recover the session, but no state is preserved. Most applications will want to call GeckoSession.load(org.mozilla.geckoview.GeckoSession.Loader) or GeckoSession.restoreState(SessionState) at this point.
      Parameters:
      session - The GeckoSession for which the content process has crashed.

    • onKill

      @UiThread default void onKill(@NonNull GeckoSession session)
      The content process hosting this GeckoSession has been killed. The GeckoSession is now closed and unusable. You may call GeckoSession.open(GeckoRuntime) to recover the session, but no state is preserved. Most applications will want to call GeckoSession.load(org.mozilla.geckoview.GeckoSession.Loader) or GeckoSession.restoreState(SessionState) at this point.
      Parameters:
      session - The GeckoSession for which the content process has been killed.

    • onFirstComposite

      @UiThread default void onFirstComposite(@NonNull GeckoSession session)
      Notification that the first content composition has occurred. This callback is invoked for the first content composite after either a start or a restart of the compositor.
      Parameters:
      session - The GeckoSession that had a first paint event.

    • onFirstContentfulPaint

      @UiThread default void onFirstContentfulPaint(@NonNull GeckoSession session)
      Notification that the first content paint has occurred. This callback is invoked for the first content paint after a page has been loaded, or after a onPaintStatusReset(GeckoSession) event. The function onFirstComposite(GeckoSession) will be called once the compositor has started rendering. However, it is possible for the compositor to start rendering before there is any content to render. onFirstContentfulPaint() is called once some content has been rendered. It may be nothing more than the page background color. It is not an indication that the whole page has been rendered.
      Parameters:
      session - The GeckoSession that had a first paint event.

    • onPaintStatusReset

      @UiThread default void onPaintStatusReset(@NonNull GeckoSession session)
      Notification that the paint status has been reset.

      This callback is invoked whenever the painted content is no longer being displayed. This can occur in response to the session being paused. After this has fired the compositor may continue rendering, but may not render the page content. This callback can therefore be used in conjunction with onFirstContentfulPaint(GeckoSession) to determine when there is valid content being rendered.

      Parameters:
      session - The GeckoSession that had the paint status reset event.

    • onPointerIconChange

      @UiThread default void onPointerIconChange(@NonNull GeckoSession session, @NonNull PointerIcon icon)
      A page has requested to change pointer icon.

      If the application wants to control pointer icon, it should override this, then handle it.

      Parameters:
      session - The GeckoSession that initiated the callback.
      icon - The pointer icon sent from the content.

    • onWebAppManifest

      @UiThread default void onWebAppManifest(@NonNull GeckoSession session, @NonNull JSONObject manifest)
      This is fired when the loaded document has a valid Web App Manifest present.

      The various colors (theme_color, background_color, etc.) present in the manifest have been transformed into #AARRGGBB format.

      Parameters:
      session - The GeckoSession that contains the Web App Manifest
      manifest - A parsed and validated JSONObject containing the manifest contents.
      See Also:

    • onSlowScript

      @UiThread @Nullable default GeckoResult<SlowScriptResponse> onSlowScript(@NonNull GeckoSession geckoSession, @NonNull String scriptFileName)
      A script has exceeded its execution timeout value
      Parameters:
      geckoSession - GeckoSession that initiated the callback.
      scriptFileName - Filename of the slow script
      Returns:
      A GeckoResult with a SlowScriptResponse value which indicates whether to allow the Slow Script to continue processing. Stop will halt the slow script. Continue will pause notifications for a period of time before resuming.

    • onShowDynamicToolbar

      @UiThread default void onShowDynamicToolbar(@NonNull GeckoSession geckoSession)
      The app should display its dynamic toolbar, fully expanded to the height that was previously specified via GeckoView.setDynamicToolbarMaxHeight(int).
