无法在模拟器或真实设备中运行Flutter应用程序

Question

我想看看使用Flutter进行开发是什么感觉。 我已经按照https://flutter.dev/docs/get-started教程完成了所有设置，但我遇到了一个错误，在尝试在模拟器或我的OnePlus 5T上运行应用程序时都会出现错误

我已重新启动adb，将我的手机置于文件传输模式，检查扑了医生 - 没有错误。

这是错误日志（对于模拟器和我的手机都是一样的）

Answer 1

检索ro.product.cpu.abi的设备属性时出错：

此问题与Android Studio的新更新有关（29）

暂时有一个临时修复（如果你使用的是Windows）！

1.关闭Android Studio

2.打开CMD并写入： taskkill /f /im adb.exe

3.下载此文件： http ： //dl-ssl.google.com/android/repository/platform-tools_r28.0.2-windows.zip

4.转到

C：\\用户[你-名] \\ AppData \\本地\\的Android \\ SDK

并将“platform-tools”文件夹替换为刚刚下载的新文件夹。

ps：（a）不要忘记保留备份（b）AppData是一个隐藏文件夹
