is it possible to create a custom file system or use an existing file system like EncFs to read data inside Android environment.
My idea is to make a virtual filesystem for storing some media files and developing an app which can directly access those files from the filesystem volume.
I hope im clear with my question.!!
Yes, but you need a rooted devices to use it. Or, you need to build your own firmware. Here’s one, it’s open source: http://nemesis2.qx.net/pages/LUKSManager
