How to add fonts folder on Android Studio?

Question

I'm developing an android app using Android Studio IDE, and i want to use customized fonts in this app.

I know that i have to create a folder called 'fonts' under the folder 'assets', but i can't.
All the time that i try, i have this:
res
-assets.fonts
Instead off:
res
-assets
--fonts

How can i create this folder?
I'm newbie on android development, so sorry about something.

In Android Studio, you can create assets directory under src/main.

So it looks like this

- src
  - main
    - java
    - res
    - assets
      - fonts

Update

Recent support library(from 26.0) officially supports fonts as Resource.

To use this, put fonts into src/main/res/font/,

- src
  - main
    - java
    - res
      - font

Now you can use font as R.font.xxx

In layout xml

android:fontFamily="@font/myfont"

Or programmatically

Typeface typeface = ResourcesCompat.getFont(context, R.font.myfont);
textView.setTypeface(typeface);

This feature also enables you to create font family. Further information is on official docs.

You can also use Downloadable Font.
