我在Kivy身上遇到了很大的问题。你能救我吗？
我为我公司开发了库存控制应用程序。我的公司使用Oracle数据库。我用Kivy编写代码，Python和我使用cx_Oracle来连接我们的数据库。它在我的PC上工作完美。但它不适用于我的Android手机。我使用Buildozer构建了一个APK。我拿错误后，写日志。这是我得到的错误：
python : ImportError: No module named cx_Oracle
我的Android手机未找到cx_Oracle。我没有在手机上访问Oracle数据库，应用程序无法运行。有什么方法可以建议吗？

您需要在APK中包含cx_Oracle模块。但是，cx_Oracle是一个已编译的C模块，因此python-for-android需要recipe才能编译它（参考here是所有现有的配方）。还没有这样的配方，但你可以尝试写一个。您可能需要CompiledComponentsPythonRecipe。
