Create a text file, named hello.txt, and save it in the folder /res/raw. The files inside /res/raw will be traded as raw files, they will not be compiled. They will be moved to application package as they are.

Very useful tutorial indeed. I am glad that I was able to find this. I have a question though and hope you can help me with. The question is,
ReplyDeleteHow can I read a file that has different independent paragraphs and display using textview and also be able to use shownext() and showPrevious(). Or how can I read more than one file in the res/raw folder and use showNext(), showPrev() methods to display in the view.
Thanks in advance. I am new to Java/Android and trying to learn.
