Flutter 无法在 Android 上构建 App，因为它在 JDK 安装中找不到所需的工具

Question

我可以为 Linux 设备构建带有 flutter 的应用程序，但我不能为任何连接的设备构建应用程序。当我运行 flutter doctor 我得到

[✓] Flutter (Channel master, 1.24.0-8.0.pre.277, on Linux, locale en_NG)
[✓] Android toolchain - develop for Android devices (Android SDK version 30.0.2)
[✓] Linux toolchain - develop for Linux desktop
[!] Android Studio (not installed)
[✓] Connected device (2 available)

! Doctor found issues in 1 category.

但我安装了 Android Studio 问题是我什至不使用 Android Studio，我使用 Visual Studio 代码，但由于其他一些问题我安装了它。

现在的问题是每当我尝试在我已连接的 Android 上构建应用程序时：

$ flutter devices
2 connected devices:

SM A505F (mobile) • RZ8M902VAZK • android-arm64 • Android 10 (API 29)
Linux (desktop)   • linux       • linux-x64     • Linux

我收到错误

$ flutter run -d RZ8M902VAZK

但我安装了 JDK：

$ java -version
openjdk version "1.8.0_275"
OpenJDK Runtime Environment (build 1.8.0_275-8u275-b01-0ubuntu1~18.04-b01)
OpenJDK 64-Bit Server VM (build 25.275-b01, mixed mode)

非常感谢！！

打开 Android studio 并安装 Flutter Plugin 这将解决您的 Flutter 问题

和

> Kotlin could not find the required JDK tools in the Java installation '/usr/lib/jvm/java-8-openjdk-amd64/jre' used by Gradle. Make sure Gradle is running on a JDK, not JRE.

设置为/usr/lib/jvm/java-8-openjdk-amd64/jre

应将 JAVA_HOME 设置为 /usr/lib/jvm/java-8-openjdk-amd64/

为您的用户在 Mac OS X 或 Linux 上设置 JDK 路径

登录并打开终端或命令行 window。
使用 vi 或其他命令行编辑器（例如 Pico）打开 ~/.bash_profile。
例如输入vi ~/.bash_profile.
将您的 PATH 设置为包含名为 java 的 JDK 子文件夹。对于 example:export PATH=$PATH:/usr/java/jdk1.6.0_10/bin 保存更改并注销然后返回，或者，要激活新设置，请输入 source ~/.bash_profile
