安卓和 ICU 5.0

Question

我开始在我的 Android 项目中使用 ICU4J。但是当我在设备上运行该项目时，在启动时，我遇到了崩溃。这是错误:

似乎 ICU 源需要更多文件，但我添加了我在 jar 中找到的所有源...如果有人有同样的问题或只是有解决方案......谢谢!

编辑:刚刚有这些警告:

好的，我找到了这个问题的答案。显然，您不能只为 ICU 下载完全构建的 .jar 文件并将其放入。它不包含数据文件。

您必须:

1. 下载 .tgz 文件，上面写着“gzipped tar archive including the entire source package”
2. 解压缩该文件并 cd 到该目录
3. 运行“ant”来自己构建 ICU4J
4. 它将创建一个 icu4j.jar 文件，其中包含您需要的数据文件。您可以将其放入您的 libs 目录并修改您的 gradle build.gradle 文件以包含它

如果在他们网站的某处对此进行了解释，或者如果他们实际提供了包含数据文件的 .jar 文件，将会有所帮助。这导致了大约一天的头痛，所以希望这对其他人有所帮助。
