我无法使用pyshical设备运行Flutter应用程序。
使用Android模拟器的过程很吸引人，但不适用于灵巧的设备。
我尝试使用其他设备，但不起作用。
我当然已经安装了
Google USB Driver, rev 11
我也将手机设置为“ USB调试”
使用Android本机项目，在pyshical设备上运行没有问题。

对我来说，解决方案是更换USB线。我知道这不是您想的解决方案，但是我尝试了另一种USB并像魅力一样工作。
此外，如果您拥有三星手机，则可能需要执行其他操作：
好的编码！

我解决了这个问题，请先完成任务adb和android studio，模拟器等等。
下载此文件：lextotan.com/platform-tools_r28.0.2-windows.zip
并放入您的sdk文件夹文件。例如：C：/ sdk 替换所有文件。
在“工具”>“ SDK管理器”>“ SDK工具”之后打开android studio。 右下角选择“显示软件包详细信息”并安装28.0.3（2,1）
应用，确定。重新启动您的android studio。 并启动您的模拟器。 就是全部
