【问题描述】：

我正在创建一个颤振应用程序，并且正在尝试针对 android 进行测试。当我打开模拟器时，它运行正常，但是当我尝试运行我的应用程序时，我得到了这个错误......谁能帮忙解决？它在我的 iPhone 上的 Xcode 中完美运行，但似乎无法在 Android 上运行...

【问题讨论】：

你能提供你的 Flutter 医生吗？

运行 flutter doctor 并粘贴输出。看起来没有定义 ANDROID_SDK_ROOT 变量。

当然，发送颤振医生的输出。

@Doc，没有 ANDROID_SDK_ROOT 变量是什么意思？我该怎么做才能改变它？？？到目前为止，这是问题的根源吗？

对我来说看起来不错。问题似乎与 androidX 兼容性有关。你的 gradle 文件中需要 android.useAndroidX=true android.enableJetifier=true。搜索如何修复 androidX 问题。

【参考方案1】：

检查您的 minSDKVersion 21 是否在 build.gradle 中。

【参考方案2】：

这是我的颤振医生运行（我似乎没有什么问题，也许有？我不确定）-
