flutter - 如何修复 "Error retrieving device properties for ro.product.cpu.abi:"Android Studio - Flutter

Question

当我第一次在 Flutter 官方网站的文档帮助下安装 flutter 时。并且还将 Android studio 设置为 flutter 的 IDE。之后，步骤引导创建一个新的 flutter 项目，并在模拟器/实际设备上运行应用程序的样板代码，以计算用户按下按钮的次数。但它每次都抛出未处理的异常。

我试过在模拟器和实际上运行，但都只抛出错误。如果有人对 flutter 有所了解，请帮助我，因为我是 flutter 环境的新手。有关详细信息，请参阅代码。

//**********************main.dart**************************
import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        // This is the theme of your application.
        //
        // Try running your application with "flutter run". You'll see the
        // application has a blue toolbar. Then, without quitting the app, try
        // changing the primarySwatch below to Colors.green and then invoke
        // "hot reload" (press "r" in the console where you ran "flutter run",
        // or simply save your changes to "hot reload" in a Flutter IDE).
        // Notice that the counter didn't reset back to zero; the application
        // is not restarted.
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

/// same as boilerplate code in any flutter new app

Error retrieving device properties for ro.product.cpu.abi:

此问题与Android Studio(29)的新更新有关

目前有一个临时修复程序(如果您使用的是 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:\Users[your-username]\AppData\Local\Android\Sdk

并将“platform-tools”文件夹替换为您刚刚下载的新文件夹。

ps:(a)别忘了备份(b)AppData是一个隐藏文件夹(一开始你可能看不到)
