Searching an Android App (for editing PDFs)

Hello People,


I looking ahead to buy the upcoming Nvidia Note. Its OS is Android, the latest Version as far as I read.
I would like to use it for university, because its small and the akku time was about 10 -11 Hours enough for me. So now I want to know is there an app on android which allow me to open PDFs and edit them.
Like marking or taking notes (Nvidia Note also got a special pen for that use). If yes, would be kind of nice if you can send me the link or maybe have experience with it and tell me how its working.

Thanks for your Time and Help.

Greetings Templum
