cancel method

void cancel()

Cancels the render in progress.

The render stops immediately and its onComplete callback receives GemError.cancel. Start the next render from that callback: until it is called, start returns GemError.inUse. Does nothing when no render is in progress.

  objectMethod(pointerId, 'ActivityVideoPreview', 'cancel');
}
