My app has .txt files in subdirectories in the assets folder. It reads those .txt files and puts them in a textview. It\'s working great and no problems.
Should I be
Yes and No.
A normal user would not be able to delete them, but a user on a rooted phone who doesn't know what they're doing… that's a different situation.
If you ask me, the extra code is not needed. Also if you try and open a file that doesn't exist, you will get an exception thrown at some point, catch that and display a dialog if you really want to.
