提示marketplace plugins are not loaded.check the internet connection and refresh
解决办法：Setting>Appearance & Behavior>Syetem Setting>HTTP Proxy勾选Auto-detect proxy settings、Automatic proxy configuration URL，Automatic proxy configuration URL后面填https://plugins.jetbrains.com/ 解决
可能会不稳定，多试几次，我的就出现过刚刚好了一会儿又报marketplace plugins are not loaded.check the internet connection and refresh
还出现过插件列表加载出来了但点击安装时报Plugin Genymotion download or installing failed
Plugin Genymotion was not installed: Cannot download 'https://plugins.jetbrains.com/pluginManager/?action=download&id=com.genymotion.idea&build=AI-192.7142.36&uuid=67a2cb5c-24e6-4225-89af-5aa7ec352c34': Software caused connection abort: recv failed错误的情况，多试几次就好了
