typeface not applied no error thrown

Question

Im trying to apply typeface to textviews and editTexts but the typeface silently fails with no error or exception in logs.There is no change in font and android default font is shown.

I have tried around 10 fonts nothing works(otf & ttf both) nothing worked

I also tried to convert it http://www.freefontconverter.com/ here as some answers suggested. But, still not working.

 typefaceLight = Typeface.createFromAsset(getAssets(), "fonts/MyriadProRegular.otf");
//        typefaceBold = Typeface.createFromAsset(getAssets(), "fonts/HNBold.otf");
//                typefaceBold = Typeface.createFromAsset(getAssets(), "fonts/Helvetica.ttf");
        typefaceBold = Typeface.createFromAsset(getAssets(), "fonts/HelveticaBold.ttf");
        typefaceLight = Typeface.createFromAsset(getAssets(), "fonts/HelveticaLight.ttf");
        typefaceArialBold = Typeface.createFromAsset(getAssets(), "fonts/helveticabold1.ttf");
//        typefaceLight = Typeface.createFromAsset(getAssets(), "fonts/HNLight.otf");
        registerTitleTv.setTypeface(typefaceBold);
        signInTittleTv.setTypeface(typefaceBold);
        termsSiginTextView.setTypeface(typefaceLight);
        termsSignUpTextview.setTypeface(typefaceLight)
