Q:

RuntimeException: native typeface cannot be made

I'm trying to use a custom font on elements of a listview. So in my ListViewAdapter constructor I have:
private Context context;
private List<Project> projects;
private Typeface tf;
public ListViewAdapter(Context context, int resource, List<Project> projects) {
    super(context, resource, projects);
    this.context = context;
    this.projects = projects;
    tf = getTypefaceForListItems();
}

public Typeface getTypefaceForListItems()
{
    return Typeface.createFromAsset(context.getAssets(), "fonts/OpenSans-Regular.ttf");
}

In getView method I apply this typeface to a textview. The problem is that I get a Runtime exception: native typeface cannot be made and I don't understand what seems to be the problem.
Here's the stacktrace:

Also I wanted to mention that all my fonts are in src/main/assests/fonts folder. 

A:

One problem that's overlooked (by Android Studio users) is that the "assets/" folder is NOT on the same level as "src/". It is INSIDE "src/main/"
Because I didn't see this earlier, I spent two hours last night, and an hour this morning just trying to change the font in my navigation drawer.
I believe this is the same reason why pixlUI and calligraphy libraries did not work for me.
