Question

我正在尝试使用仿真器，当我启动它时，它开始加载，但在VSCode中没有连接。如何连接以便VSCode检测到它？

启动adb服务器时，得到以下输出

Answer 1

该设备没有权限。运行flutter doctor和flutter devices，如果似乎没有连接任何设备（在本例中为仿真设备），则需要kill adb-server，打开仿真器，然后启动{ {1}}。

如果在此之后问题仍然存在，请尝试adb-server

如果仍然继续，请发布您的flutter doctor --android licenses和flutter doctor输出。

致谢

通常，对于 IDE 和仿真器，只需重新启动就足够了。但是在某些情况下，最好重新启动计算机。在这些解决方案中，您可以尝试重新启动adb服务器。

adb kill-server
adb start-server

可选： 另外，如果要使用不带电缆的设备，则可以启动设备，然后可以无线使用adb（如果设备不具备此功能。现代设备内置此选项。）

使用Flutter在VSCode中未检测到模拟器
