Android和ICU 5.0

我开始在我的Android项目中使用ICU4J。但当我在设备上运行项目时，在启动时就会崩溃。以下是错误信息:

看起来 ICU 源代码需要更多的文件，但我已经在 jar 包中添加了所有我找到的源代码... 如果有人遇到同样的问题或者有解决方案... 谢谢！

好的，我找到了解决这个问题的答案。显然，你不能只下载ICU的完整构建的.jar文件并将其放入项目中，因为它不包含数据文件。

你必须：

下载那个标有“gzipped tar archive including the entire source package”的.tgz文件
解压缩该文件并进入该目录
运行“ant”来自己构建ICU4J
它将创建一个包含所需数据文件的icu4j.jar文件。你可以将其放入libs目录中，并修改gradle build.gradle文件以包含它。

如果在他们的网站上有这方面的说明或者提供了包含数据文件的.jar文件，这会很有帮助。这导致我花了一整天的时间才解决问题，希望这能帮助其他人。
