无法从代号为one的初始化程序生成Android apk

Question

基本上我是从 https://start.codenameone.com/

获取应用程序

如果我从命令行进行 Maven 编译，则会生成构建成功并生成一个 jar 文件。

我可以在模拟器中的 Eclipse 中运行该应用程序，从而生成 hello world 应用程序。

当我尝试构建 Android APK 时，会导致 Eclipse 构建错误。

在通过 Eclipse 构建时，我首先收到此错误

这应该是“运行 ANT 构建目标 android-source”吗？

当我使用 android studio 打开应用程序并尝试进行构建时，我无法进行构建，因为没有菜单选项可以进行构建。

类似，但对我没有帮助。 https://www.reddit.com/r/androiddev/comments/uqpefi/android_studio_build_menu_generate_apk_option/?rdt=34262

android build studio 中应该还有一些菜单选项 例如：

-> 构建捆绑包

-> 生成签名包 apk

注意，android SDK是通过环境变量引用的。

ANDROID_HOME=C:\Android\sdk

系统路径下的Android studio64.exe（c:\Android\Android Studio中）

我使用的是windows 10，java版本是11.0.21

我希望以上所有内容对某些人来说有意义。感谢您的阅读:)

关于我在制作 APK 时缺少的内容有什么想法吗？

Answer 1

Android 原生构建仅适用于 Java 8，因为它依赖于 Java 9 从 JDK 中删除的 JAXB。确保在 eclipse 中设置 JDK 8 以进行构建。 这应该可以解决第一个错误。

您看到的第二个错误是当我们尝试在 Android Studio 中为您打开项目时。我们找不到应该执行此操作的 windows

start

命令，我不确定为什么它不起作用。这不是致命错误，因为项目生成为

C:\work\programming\codenameone\exxxxdmobile\android\target\exxxxdmobile-android-1.0-SNAPSHOT-android-source

，您可以手动打开它。

这应该是“运行 ANT 构建目标 android-source”吗？

是的。 Maven 代码依赖于我们的一些旧 Ant 代码，并在此基础上构建。

关于最后一个错误，有点难以判断项目或环境出了什么问题。我需要有关您的 Android Studio 设置的更多详细信息，以及打开项目时是否有任何警告。我认为 Android Studio 需要 JDK 17，因此请确保它具有该版本。

此外，您的启动项目似乎使用旧版本的 Codename One (86)，您现在可以更新到 133。
