I am downloading certain types of files in my app (pdf, ppt, doc, mp4, etc). Right now I am launching these files in their default applications in the device. Is there any way that I might open these inside my own app?
I have explored other similar questions, I am currently trying out apache poi api for my purpose but I am not sure it will work on all types of files.
I want to know if I have to decode and render these formats in my own applications, what kind of an effort will that take? And also, since I don't know where to start, is there reference available from which I could get help?
Thanks in advance.
