离子在设备上运行应用程序

Question

我尝试使用 ADB 在我的设备中运行我的 Ionic 应用程序，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

我没有在设备上安装应用程序，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?

Answer 1

首先，您需要清理代码。因为所有'进口都是未使用的。'。删除代码中未使用的所有导入。
要在移动设备上运行您的 Ionic 应用程序，请按照以下步骤操作：

• 运行此命令

  $ adb 设备

如果您的设备已连接，您将得到如下输出：

List of devices attached 
02003106B2303888    device

• 现在，启动您的应用程序：

  $ ionic cordova run android --target=02003106B2303888

Answer 2

我缺少 Android 7 SDK，我安装了它并且它工作正常！
