My custom font does not work

The cause of this issue is badly formed TTF font files. Minor issues in font files may be ignored or tolerated by most systems rendering the font, however the tolerance level in the early builds of Lollipop was not so high and some fonts fail to render causing the system to fall back to using the default font.

  2. Select target format to TTF
  3. Download result file
  4. Unzip the downloaded file and copy the TTF font file to your font folder
