Flutter医生报告看到安装了两个Android Studio

Question

为什么Flutter会在同一位置报告有效和无效的Android Studio安装？遇到的错误如下：

当我加载AS并运行默认应用程序时..我在事件日志中得到了它：

Please run "flutter doctor" to diagnose potential issues

11:13 AM    Emulator: Couldn't statvfs() path: No such file or directory

谢谢您能协助解决这个问题。

Answer 1

我建议清除android-studio-dir和android-sdk设置，然后让flutter自动检测其路径：

$ flutter config --android-studio-dir=""
Removing "android-studio-dir" value.

$ flutter config --android-sdk=""
Removing "android-sdk" value.

Answer 2

以下两个flutter命令解决了该问题！！！ ...

try{
horeca_medal = (ImageView)getApplicationContext().findViewById(R.id.horeca_medal);
//Write your own reference.

horeca_medal.setImageResource(R.drawable.first);

    if (pst <= 0) {
        horeca_medal.setImageResource(R.drawable.first);
    } else if (pst == 1) {
        horeca_medal.setImageResource(R.drawable.second);
    } else if (pst == 2) {
        horeca_medal.setImageResource(R.drawable.third);
    } else if (pst > 2 && pst < mTopHorecas.size()){
        horeca_medal.setVisibility(View.INVISIBLE); //This edit
    } else {
        horeca_medal.setImageResource(R.drawable.first);
    }
}catch(Excaption ex)
{
android.util.Log.e("YourError", ex.getMessage());
}

Answer 3

删除包含Android Studio早期版本的配置文件的文件夹即可解决此问题。 更新后，我有2个版本的Android Studio。

.AndroidStudio3.3 
.AndroidStudio3.4

所以我删除了3.3（.AndroidStudio3.3）版本的配置文件，只保留了3.4（.AndroidStudio3.4）版本的配置文件

如果您是Ubuntu用户并且对Android Studio进行了默认安装，则可以在主目录中找到这些文件夹。这些文件夹是隐藏的，因此您必须先取消隐藏它们。

在更新后出现提示时，请确保导入先前的设置，否则在删除旧的配置文件之前，您将必须重新安装所有使用的依赖项。
