App crashes when changing textview font

App crashes when changing textview font

I'm trying to change textView's font programatically and my app keeps
crashing. This is how I'm doing it:
//SET CUSTOM FONT FOR TIMER
String fontPath = "fonts/voice_notepad_font.ttf";
TextView timer = (TextView)findViewById(R.id.timer);
Typeface tf = Typeface.createFromAsset(getAssets(), fontPath);
timer.setTypeface(tf);
This is the font I'm using

I added the custom font to assets/fonts folder and renamed it to
'voice_notepad_font'
