等待VM服务端口可用

Question

我尝试在具有 API 35 的 Android 模拟器上的 Android Studio 上运行默认应用程序，但每次运行 flutter run -v 命令时，该应用程序都会卡在行中：

Waiting for VM Service port to be available

，如果我执行

flutter run 

卡在

Built build/app/outputs/flutter-apk/app-debug.apk

flutter doctor 没有给我显示任何问题。这是

flutter doctor -v

的输出：

这是

flutter run -v

输出：

应用程序始终处于白屏状态，并带有 Flutter 徽标。

我发现很多人都有同样的问题，但他们的解决方案都不适合我，build.gradle中的包名称与manifest.xml和mainActivity中的名称相同

Answer 1

尝试

flutter run --release

或

flutter run --profile

。如果也失败了，那么你的 adb 很可能已损坏。尝试重新安装adb。

哦，你也尝试过

flutter clean

吗？
