First of all, do you even have the Times Roman font installed on your device? And secondly, the main font, has about six subfiles for the variations (block, italics, italics-bold, etc)
I recently found that my Galaxy Note Pro, only has about 10 fonts installed. My NAS has about 30,000 though, and many are what are called font groups, and require the installation of six or more files for the complete font.
Also, for an android device, you NEED the unicode version, with is considerably larger, and contains all the glyphs for all the languages within your language group. English is part of the Latin group for instance, which also contains about 45 other languages. So just throwing a font file onto Android, which is an International device, is not like using fonts in Windows. You should be safe if the font files come from Windows 8 and newer (not Win7), or sources online that speciiccaly state thay will work on Mac Snow Leopard, Windows 8 or Android KitKat or newer.
An example, the Ariel font is about 6 Mb in Windows 7, and 30Mb for the international version.
