Flutter 应用程序未在真实设备上运行

Question

我正在尝试在我的手机上使用我的 Flutter 应用程序，但是当我运行时

flutter run  --verbose

我收到了这个错误：

   +2 ms] Stopping app 'app.apk' on SM A315G.
[        ] executing: /mnt/SSDP/Sdk/android/platform-tools/adb -s RR8R107K94E shell am force-stop com.parsapp

在移动开发者选项中

1. USB 调试已开启
2. 通过 USB 验证应用已开启
3. 验证可调试应用的字节码已关闭
4. 我有足够的空间（超过 100 gig 可用空间）

然后我选择传输图像

当我选择传输文件时，午餐过程保持在这个级别：

但是我不能在我的手机上午餐应用程序。

这是颤振医生：

Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel unknown, 2.0.6, on Linux, locale en_US.UTF-8)
[✓] Android toolchain - develop for Android devices (Android SDK version 30.0.3)
[✓] Chrome - develop for the web
[✓] Android Studio
[✓] VS Code (version 1.56.2)

我正在使用 FVM。而我的手机安卓版本是11。

当我运行 adb install /mnt/SSDP/Project/Casp/mobileapplication/build/app/outputs/flutter-apk/app.apk 时卡在 Performing Streamed Install。

Answer 1

你的flutter频道未知。

版本未知，似乎处于网络开发者模式，所以

如果你在安卓设备上使用它，最好切换到

flutter channel stable

之后

flutter upgrade

然后 flutter run

Answer 2

我终于解决了这个问题：

运行flutter doctor -v 如果你遇到insufficient permissions for device 错误，你应该这样做：

1. 根据official site

如果您看到一条错误消息，指出您不在 plugdev 组中，您需要将自己添加到 plugdev 组：

sudo usermod -aG plugdev $LOGNAME

然后：

android-sdk-platform-tools-common 包包含由社区维护的 Android 设备默认 udev 规则集。安装：

apt-get install android-sdk-platform-tools-common

1. 如果以上提示不起作用then:

   adb kill-server

然后用超级用户启动adb或使用sudo

sudo adb start-server

完成:-)
