如何在 Flex Mobile Project 中显示本地 PDF? [英] How to display local PDF in Flex Mobile Project?

问题描述

我正在运行 Flex 移动项目，我希望我的移动应用程序能够加载和显示本地保存的 pdf 文件.我不想上网访问这些 pdf 文件.

I am running Flex mobile project and I would like my mobile app to be able to load and display pdf files that are saved locally. I do not want to go out to the web to access these pdf files.

我不知道如何使此代码适用于本地保存的文件.

I cant figure out how to make this code work for a locally saved file.

错误消息:错误 #2044:未处理的错误事件:.text=加载错误."

Error MSG: "Error #2044: Unhandled ErrorEvent:. text=Load error."

有人有什么建议吗?
谢谢！

Does anyone have a suggestion?
Thanks!

推荐答案

Android 问题实际上是一个基本的 Android 浏览器操作系统问题.将 AIR StageWebView 视为从您的应用程序中雕刻出来的一个洞，向您展示浏览器及其所有功能.

The Android Issue is actually a fundamental Android Browsers OS Issue. Think of the AIR StageWebView as a Hole carved out of your app showing you the browser and all its capabilities.

如果您的操作系统支持查看 PDF，那么您的应用程序的 StageWebView 也将支持.在 Android 1.0 - 3.0 上，当您尝试查看 PDF 时，它会下载文档并将其手抖到另一个应用程序(如 Acrobat)上.

If your OS supports viewing PDFs, then your App's StageWebView will also. on Android 1.0 - 3.0 when you try and view a PDF it will download the doc it and Hand Shake it off onto another application like Acrobat.

希望这将在最新版本的 Android...4.0 中得到修复

Hopfully this will be fixed in the newest version of Android...4.0
