我有这个安装在我的Android经理
当我在Windows上运行我的离子2应用程序时（ 离子运行android ），我也有同样的问题，我通过以下步骤解决它，希望它会帮助你。
1-开始你的Android Studio 。
2-创build一个新项目 ，以便能够创build或删除虚拟设备。
3-删除任何虚拟设备，如果find。
4-通过AVDpipe理器创build虚拟设备，如下所示。
首先试试这个：如果你正在使用一个设备。 那么只要确保设备连接良好。 检查在Android工作室，设备在线。 这个错误通常在设备脱机时popup。
如果您使用Xamarin，请转至工具 – > Android – >重新启动Adb服务器。
