由于大多数我们需要显示已托管在网络上的文件，我们选择使用打开使用的google文档查看器。

Since most of the documents we need to display are already hosted on the web, we opted to use an embedded web view that opens the document using google docs viewer.

我们还是有，虽然这种方法不能处理一些本地存储的文件。对于这些，我们的解决方案是依靠现有的应用程序的支持。花一些时间与Android之后，它似乎大多数设备都配备了某种形式的文件/ PDF阅读能力，安装新的开箱即用。的，因为它们不具有能够应用程序的情况下，我们引导它们向市场搜索一个免费的阅读器。

We still have a few locally stored documents though that this approach doesn't work with. For these, our solution was to rely on the support of existing apps. After spending some more time with Android, It seems that most devices come equipped with some sort of document/pdf reading capability installed fresh out of the box. In the event that they don't have a capable app, we direct them to a market search for a free reader.
