Note the error occurs only if navigation is performed with animated=false (no transition).\r\n\r\n**To Reproduce**\r\nUsing `e2e/nested-frame-navigation`: \r\n1. Go to  _Page w/ BOTTOM NAVIGATION_\r\n2. _Navigate to some page (no transition)_\r\n3. Go back -- app crashes with the following exception:\r\n```\r\nAn uncaught Exception occurred on \"main\" thread.\r\nThe specified child already has a parent. You must call removeView() on the child's parent first.\r\njava.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.\r\n```\r\n\r\n**Expected behavior**\r\nApp should not crash.\r\n\r\n**Additional context**\r\nThe same problem would occur if you tried to use three levels of Frame nesting because BottomNavigation behaves essentially as a Frame with respect to Android fragment lifecycle.\r\n","author":{"url":"https://github.com/ADjenkov","@type":"Person","name":"ADjenkov"},"datePublished":"2019-07-09T11:15:52.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/7481/NativeScript/issues/7481"}
