检索 ro.product.cpu.abi 的设备属性时出错：

Question

我无法使用物理设备运行我的 Flutter 应用程序。

使用 Android 模拟器就像一种魅力，但不适用于物理设备。

我尝试使用不同的设备但不起作用。

当然我已经安装了

Google USB Driver, rev 11

我还把我的手机设置为“USB调试”

使用 Android 原生项目，我在 pyshical 设备上运行没有问题。

Answer 1

使用 USB 进行文件传输 和 USB 调试 对我有用

使用 USB 为本设备充电时

$ flutter doctor
Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel stable, v1.5.4-hotfix.2, on Linux, locale en_IN)
⣻Error retrieving device properties for ro.product.cpu.abi:
error: insufficient permissions for device: user in plugdev group; are your udev
rules wrong?
See [http://developer.android.com/tools/device.html] for more information



[✓] Android toolchain - develop for Android devices (Android SDK version 29.0.0)
[✓] Android Studio (version 3.4)

使用 USB 传输文件时

$ flutter doctor

Answer 2

只需下载此平台工具并将其替换为

C:\Users\User-name\AppData\Local\Android\Sdk\platform-tools

Windows：http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-windows.zip
macOS：http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-darwin.zip
Linux：http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-linux.zip

Answer 3

我解决了这个问题，请先结束任务 adb 和 android studio，emulator 等等。

下载这个：lextotan.com/platform-tools_r28.0.2-windows.zip

并把你的 sdk 文件夹文件 .示例：C:/sdk 替换所有文件。

在 Tools>Sdk manager>Sdk Tools 之后打开 android studio。 右下角选择 Show Package Details 并安装 28.0.3(2,1)

申请并确定。重启你的安卓工作室。 并启动你的模拟器。 多谢了

Answer 4

您可以按照此链接https://github.com/flutter/flutter/issues/33938#issuecomment-499250288 中的步骤进行临时修复。它对我有用。

Answer 5

我的解决方案是关闭 IDE 并断开设备与计算机的连接，然后重新连接。

Answer 6

我的解决方案是更换 USB 线。我知道这不是您想的解决方案，但我尝试使用另一个 USB 并像魅力一样工作。

此外，如果您有三星手机，您可能还需要做其他事情：

• 安装Smart Swith - Samsung
• 安装Android USB driver for Windows

编码不错！
