我试图在我的设备中使用ADB运行我的Ionic App，检测到我的设备，我将android平台添加到我的项目中，一切都很好，但是当我运行时
ionic cordova run android --device
我没有在设备上获取应用程序，这是我的控制台日志：

[OK] Your app has been deployed.
Did you know you can live-reload changes from your app with --livereload?
答案 0 :(得分：0)
首先，您需要清理代码。因为所有'进口都未使用。'。删除代码中未使用的所有导入。
要在移动设备上运行Ionic Application，请按照以下步骤操作：
运行此命令
$ adb devices
如果您的设备已连接，您将获得类似输出的内容：
List of devices attached
02003106B2303888 device
现在，使用以下命令启动您的应用程序：
$ ionic cordova运行android --target = 02003106B2303888

我错过了Android 7 SDK，我安装了它并且有效！
