无法在Android设备上启动飘飘应用程序

Question

我正在尝试在Android设备上启动我的Flutter应用程序，直到昨天我才能够，但是今天突然间我在启动它时收到此错误：

Launching lib/main.dart on Moto G 5S in debug mode...
Running Gradle task 'assembleDebug'...

我试过删除. gradle文件夹，但不起作用。

编辑

这是我的~/。zshrc文件

export PATH=/Users/modestovascofornas/flutter/bin:$PATH
export PATH=/Users/modestovascofornas/flutter/.pub-cache/bin:$PATH
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-17.0.2.jdk/Contents/Home

Answer 1

你可以试试这个:

在IDE中打开终端，发出命令:

flutter clean

尝试再次启动该应用程序。

Answer 2

将JAVA_HOME环境变量设置为Android Studio的JRE。例如:

< code > C:\ Program Files \ Android \ Android Studio \ JRE

然后< code >使Android Studio无效并重启，然后重试。

Answer 3

删除. gradle后，您是否尝试过./gradlew净？

在Android Studio中，我发现最好通过项目结构对话框配置变量。确保您配置了渐变，JDK

尝试通过< code > gradle-wrapper . properties 升级grad le:

distributionUrl=https\://services.gradle.org/distributions/gradle-7.3.3-all.zip

并且确保您运行的是java版本11或更低版本——无论哪个版本都是Android Studio默认版本。

编辑：看到您的编辑后，我几乎可以保证问题出在jdk-17.0.2.jdk上，请务必使用捆绑的JDK并通过项目结构对话框配置路径。
