openFileInput() will not accept path separators.('/'). It accepts only the name of the file which you want to open/access. So change the statement,

InputStream in = openFileInput(String.valueOf(filepath));

to,

FileInputStream in = FileInputStream(filepath);

Also there is no need to convert filepath into String as FileInputStream can accept File types.

Documentation for ContextWrapper.openFileInput() specifically says you cannot provide a path. 

name   String: The name of the file to open; can not contain path separators.

openFileInput is for dealing with private files, which I think means files your app creates for the purpose of your app, so it would be saved in your private app data directory.

I didn't read through your entire code snippet, but assuming you are instantiating the File object correctly and you just want a FileInputStream, you should be able to just instantiate one directly:

InputStream in = new FileInputStream(filepath);

Making sure your app has permission to access files.
