android：从我的应用程序打开一个pdf，而不使用pdf查看器

I want to be able to open a pdf file from my application without any other application like pdf viewer. I don't want to make the user install an other appliation to open pdf files. Is there any open source library that I can use in my project?

https://docs.google.com/gview?embedded=true&url=http://link.to.your/pdf_file.pdf

Answer 2
