I have to ship pdf files along with my application and display them as list and when clicked each one should open in Adobe reader. I have tried placing the pdf files in /assets
If you get an ActivityNotFoundException
is because there are no application to handle that kind of content. So, in that case, I'm sure the the Adobe Reader is installed.
Also, I think you must copy the file to the SDCard for other apps to access it. They cannot access your private data directly for security reasons.
