How to properly open csv files located in the assets folder in an android application?

Question

Android

After decompiling the apk, there were a lot of csv files in assets, but when I tried to view them through notepad ++ in various encodings, it turned out to be unreadable. Why can't I make these files readable?

Answer 1

Why can't I make these files readable?

Because someone encrypted them in advance.

Answer 2

Or maybe it's not CSV files? I don’t know how it is now, but before, androyd cut some files from assets (toly .db, or .sql exactly cut), so, for example, my databases that are in assets are called * .mp3
In general - take a look in the code where they are used and see how to read them correctly, since the application has been decompiled.
