Question

VsCode的调试模式不再通过AVD或真实的android设备启动应用程序。直到昨天以前，两者都可以完美工作。

我遇到错误

在调试模式下为x86构建的Android SDK上启动lib \ main.dart ...

Gradle任务assembleDebug失败，退出代码为1

已退出（sigterm）

我跑了扑医生-v

我不得不说我绝对不知道出了什么问题。

我认为这与代码无关，是否对我的项目没有造成重大影响。除了调试控制台中的错误之外，它没有让我有其他事情。

编辑2：感谢Siavash所说的“颤抖清洁”。解决了问题！

仍然对这个问题的“原因”感到好奇。

Answer 1

感谢Siavash：从项目文件夹内部轻松清理问题（或直接使用VSCode终端）。

Answer 2

这里有一个答案。请参阅以下步骤：- 1- 转到您保存的 flutter 文件夹，运行“flutter_console.bat”文件。将打开一个控制台。 2- 输入“颤振医生”。：- 3- 它将显示您的颤振设置中的所有问题。就我而言，您可以看到：-

C:\Users\M A Hafeez>颤动医生

医生摘要（要查看所有详细信息，请运行 flutter doctor -v）：

[√] Flutter（Channel stable, 1.22.5, on Microsoft Windows [Version 10.0.19042.685], locale en-US）

flutter_run

[!] Android 工具链 - 为 Android 设备开发（Android SDK 版本 30.0.3） X 未找到 Java 开发工具包 (JDK)；您必须在 PATH 中设置环境变量 JAVA_HOME 和 java 二进制文件。您可以从 https://www.oracle.com/technetwork/java/javase/downloads/ 下载 JDK。

[!] Android Studio（未安装）

[√] VS Code（1.52.1 版）

[√] 已连接设备（1 个可用）

！医生发现了 2 类问题。

基本上我的错误是关于 Java，在遇到这个错误之前我没有安装。

希望这会有所帮助。 :)

使用VsCode和ADV或真实设备的“ Gradle task assembleDebug失败”
