The same app seems runs correctly on devices after Android 6.0. (we tested Android 6.0 and Android 9.0). And even on Android 5.1.1 device, the app works without crash. So we assume that there are some issues regarding to setting elevation on only Android 5.0.\r\n\r\n**To Reproduce**\r\nJust add following style to the Button element.\r\n\r\n```css\r\nButton {\r\n\tbackground-color: transparent;\r\n\tmargin: 0 0;\r\n\tpadding: 0 0;\r\n\tandroid-elevation: 0;\r\n\tandroid-dynamic-elevation-offset: 0;\r\n}\r\n```\r\n\r\n**Expected behavior**\r\nNo crash.\r\n\r\n**Crash log**\r\n\r\n```\r\n07-17 12:23:38.146 27527-27527/?
