我无法在安卓模拟器或安卓手机上运行颤振应用。我在 m1 mac 上安装了最近发布的 arm-mac 平台的 android studio。如果我在这里做错了什么或者是版本本身的问题，请回答。

调试控制台输出：

【问题讨论】：

你使用的是windows？如果是，则安装 jaba 并将其 bin 文件夹添加到环境变量中

错误很明显，您的机器上是否安装了Java并正确设置了环境变量？

【参考方案1】：

转到Applications然后右键单击Android Studio，然后选择“Show Package Contents”，在jre内创建一个名为jdk的新文件夹并将jre的内容复制到jdk

这是修复https://github.com/flutter/flutter/issues/76215#issuecomment-864407892的链接

【讨论】：

一定要复制，不要移动。

【参考方案2】：

我能够通过执行以下操作来解决我的问题，我将我的项目与 Gradle 文件同步

我下载了 Java 8（但我认为这不是这个人做的）
