how to use the default typeface when failed to load custom typeface?

Question

I'm trying to load custom typeface.

It's working okay in a new model phone, but making an error in old model when loading custom typeface.

I think old model phone doesn't support the custom typeface. I guess i need to make it alternative with default typeface.

So I tried "try and catch" for alternative way.

But it still make the same error.

Shall anybody see my code and provide any suggestions? thank you.

face = Typeface.createFromAsset(getAssets(), "fonts/letter.ttf");
    face2 = Typeface.SANS_SERIF;

    try{
    noteET.setTypeface(face);
    }catch(Exception e){
        noteET.setTypeface(face2);
    }

In Note.java, it has custom EditText which contains backgound notepad lines. I think because the custom font doesn't support it, the line height for drawing line can't be calculated.

Error Message is Below:

Your catch isn't necessary. When the custom ttf can't be loaded and you caught this error so that your App doesn't crash the default Typeface is choosen automatically.
