Apps How do I set a schedule to automatically delete files using Android Studio?

[ReiSixx9]

I want to add a command to my Android Studio app that will make it automatically delete files from a certain folder at a set interval. How do I do this?

Also, can I hide the folder (using a command) so that only my app can see it?

Sorry, I mostly only know stuff about c# and Windows Program Development, I'm new to this android stuff.

Thanks!

What command do I use to delete a certain folder then?

Also, can I hide the folder (using a command) so that only my app can see it?

All apps have an internal storage area, which is only accessible to that app.
External storage is different, and requires permission to read/write

I can set the delete command to run at a certain interval (sorry my brain just totally forgot the word for that), correct?

So if I use internal storage somebody using the phone can't see the folder, but the app can use the data inside and send it via email or upload it to a cloud?

Correct

Your app's internal storage data can't be seen by any other app, but someone connecting to the device using ADB can see everything.

Correct

Is there any way to make it so it's hidden (like a super hidden folder on windows)?

Also, where do I put the handler command? Like in the manifest or...?

I'm guessing this is the correct code, right?

final Handler handler = new Handler();
final Runnable r = new Runnable()
{
    public void run()
    {
        <some task>
    }
};
handler.postDelayed(r, 15000);

Or is it this?

 Handler handler = new Handler(Looper.getMainLooper());
        handler.postDelayed(new Runnable() {
            public void run() {
                AccelListener.this.timeout();
            }
        }, 2000);

Is there any part of this code that I need to customize (change to fit my specific program) besides the time?
