flutter：如何让Android studio和Android SDK兼容？

问题描述 投票：0回答：1

似乎从 Android studio 中升级 Android SDK 会安装不兼容的东西，我无法构建。有人知道如何解决这个废话吗？

Java SDK 似乎是 Android studio 附带的。到底如何选择新版本呢？ Android studio 设置中似乎没有提供 JDK 更新/降级版本选项。

$ flutter create --platforms android
...
Your application code is in ./lib/main.dart.

The configured version of Java detected may conflict with the Gradle version in your new Flutter app.

To keep the default AGP version Gradle version 8.3, download a compatible Java version
(Java 17 <= (Java 17 <= compatible Java version < Java 21) Java version < Java 21). Configure this Java version
globally for Flutter by running:

  flutter config --jdk-dir=<JDK_DIRECTORY>


Alternatively, to continue using your configured Java version, update the Gradle
version specified in the following file to a compatible Gradle version (compatible Gradle version range: 8.4 - 8.7):
/home/sir/software/.../android/gradle/wrapper/gradle-wrapper.properties

You may also update the Gradle version used by running
`./gradlew wrapper --gradle-version=<COMPATIBLE_GRADLE_VERSION>`.

See
https://docs.gradle.org/current/userguide/compatibility.html#java for details
on compatible Java/Gradle versions, and see
https://docs.gradle.org/current/userguide/gradle_wrapper.html#sec:upgrading_wrapper
for more details on using the Gradle Wrapper command to update the Gradle version
used.

似乎某些版本的intellij与某些版本的Java不兼容（我有Android Studio Ladybug | 2024.2.1 Patch 2）。 Gradle 从哪个版本开始支持 Java 21？

您可能认为集成安装程序会提供指导。但无论如何。

互联网建议按如下方式升级 gradle（对于 Java 21 至 8.11）...但随后就消失并使用了不正确的 Java。

android$ ./gradlew wrapper --gradle-version=8.11

Here are the highlights of this release:
 - Faster Java compilation
 - Reduced memory usage
 - Support for running on Java 20

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

For more on this, please refer to https://docs.gradle.org/8.11/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.

您是否尝试过从 

Java SE 17 Archive Downloads
安装 Java 17？

然后将当前

PATH
和
JAVA_HOME
的目录替换为
Java 17 directory

自从遇见你，

Android Gradle 插件需要 Java 17 才能运行。

所以你必须确保你正在使用

Java 17 SDK
。

它对我有用，方法是在安装 

Java 17
并替换 
system variable
PATH
和 
JAVA_HOME
后重新启动计算机，并且确保我的 Flutter 项目已针对更新的环境配置进行配置。

我通过创建一个新的 Flutter 应用程序来查看更新的构建配置文件来验证它。执行上述方法后，它可以正常运行。

还可以通过执行此命令检查当前安装的 Java，

Java --版本

顺便说一句，我安装的 Java 有 LTS。

查看您的 java 安装位置，

java在哪里

附加：

如果您正在处理多个 Flutter 项目，您可以阅读此 answer

结论：

因为我通过测试特定于平台的运行时来验证 Flutter 项目中文件的正确配置。所以我可以将它用作我的实际项目的参考，特别是通过检查插件/包来查看哪些可能会导致异常。
