My thoughts exactly.
Yes @Mateja you thought well.
But I don’t know if there is a way to record only internal audio instead of taking the outside audio.
is there any option on that?
With Kodular, no.
Also, it requires root. All android devices need to be rooted so an external application can record internal audio.

I would like to know which one .3gp .aac et is best for quality and not using much kbs or mbs?
I still need more help on how to fetch the File Name which has the saved records. I have tried this method but it gets the blank file and not what I expected.
I found nothing here.
Please I need your help once again.
Data type is very similar to mime type.Try mp3/* and see what happens.
Yet still nonthing works
If so then try this one:
audio/*
Also it is not working I don’t know why 
Then something else is wrong in blocks.
Action: android.intent.action.GET_CONTENT
Data type: audio/*
you can try the intent:
android.intent.action.PICK
I have tried it now but also it doesn’t work

But my intention is to direct a user to what he was recording so there is no need to search it.
Then you don’t have to use that activity starter. That’s for picking a file…
and that is what exactly I want
read here
and here too
So I just need after a user has recorded multiple audios and those audios have been stored on a File called SkyRadio then when he clicks the menu button goes by a name Saved Recording he should be redirected to a File 
SkyRadio then from there he can select what he wants to re-listen offline.
Please someone help. 
You could use the taifun file extension to see a list of files within a folder:
Then you put that list in a listview
