我目前正在开发一个Android应用程序，允许人们阅读宪法，问题是我只能设法获得软拷贝pdf文档。理想情况下，我想要一个允许我通过主题，问题或段落获取文档的API，我想到了多种方法来完成工作
1. Is by putting the document on the server, when user opens the app it downloads the pdf and allows them to read it(Problem with this is I won't be able to mess with the content like bold some text etc).
2. Is copying the content of the pdf into the databse and just fetching the text with a query(issue with this is I wont be able to do pagination given I put the content in one field)
这是Constitution的链接我需要一种方法，我可以通过这种方式从数据库加载数据，我可以分页，一次加载一个段落或主题。任何处于类似情况的人都可以帮助我找到最好的方法。
