you have take right path store files. there multiple options

internal storage

internal app (not accessible end users outside) cache directory (it can cleared if scheme running out of space)

external storage (verify if available , utilize it) although public there 2 types

public private (technically accessible user , other apps because on external storage, files realistically don't provide value user outside app. )

each path location can accessed different api provided android. see http://developer.android.com/training/basics/data-storage/files.html
