How to add custom fonts to AndrOpen Office

If you find "□" characters or "?" characters or strange characters or not find correct characters in AndrOpen Office, it is possible that these are caused by system fonts.

AndrOpen Office uses Android system fonts.

Sometimes system fonts are poor for international characters.

If you want to see correct characters (included CJK characters), you need to add custom fonts.

You can add custom fonts to AndrOpen Office from version 1.3.0.

You can add as follows;

Go to Configuration screen from main screen.

Push settings icon in main screen.

Enable custom font

Push check box of "Custom Font".

Make /mnt/sdcard/fonts drectory

Default font directory is /mnt/sdcard/fonts.

Make font directory by any other application.
(AndrOpen Office is not supported to make directory.)

Put fonts to /mnt/sdcard/fonts directory

Put fonts to /mnt/sdcard/fonts directory by any other fonts (or by PC).

(Change font directory)

You can change font directory (default is /mnt/sdcard/fonts) by pushing "Font Directory" in configuration screen.

(Font formats)

TrueType fonts (.TTF file) is supported.


  1. Is it possible to add other languages - like Spanish?

    Thanks for this app!!! It's great so far on my Samsung P6210!! Congratulation!

    Have a great morning! :)

  2. I don't get this. My Samsung Tablet normally shows German characters, except AAO, which shows strange characters then. Do I need to add a new font only for AAO?

    1. I think it is caused by default font. But I do not yet find how to change default font to language specific font.

  3. It is a great post. I agree with you anymore. Also great blog here with all of the valuable information you have. Keep up the good work you are doing here. Thank you for sharing such a useful post.

  4. This is very cool. You've done an awesome job with Andropen Office, thank you!

  5. please tell this apps is big 90mb+ please tell this apps sport sri lanka language (sinhales ) on my dives my dives android 4.1+ please tell


    1. Thank you for your comment. Sorry, Sinhalese is not supported.

  6. Wenn ich den Artikel richtig verstanden habe, soll ich zwei Schriftartenverzeichnisse erstellen, in beide fonts tun und anschließend den Namen in Font directory wieder ändern.
    Bei mir funkioniert das nicht ich habe es nun schon sehr oft versucht.
    Meine Version ist 2.7.1

    1. Nur einen zusätzlichen Schriftartenordner erstellen. Da hinein die Schriften kopieren. AndrOpen Office starten, auf das Zahnradsymbol tippen (Einstellungen. Bei Custom Font ein Häkchen setzen und darunter bei Font Directory den neu erstellten Ordner einstellen. Und schon erkennt AOO alle zusätzlichen (Windows)Schriften.
      Anmerkung: Sollte ein AOO-Update installiert worden sein, muss das Häkchen neu gesetzt werden!!!

  8. /mnt/sdcard/fonts did not work for me.

    I used "ES File Explorer File Manager" to find my fonts folder.

    It was at this bizarre address:


    I assume yours will be different!

    I think the eight digit number might be a 'unique' reference number for my SD card. I guess that's what some newer Androids do.

    Anyway, I am absolutely thrilled with the result: full on-screen WYSIWYG for my obscure collection of favourite fonts.

  9. vender app is a productive app that will help your lifestyle!

  10. This post is really "expert friendly" and I say that having spent 30+ years in software development on many platforms and having a book on the Dr. Dobb's list of recommended reading for all developers.

    1) since you didn't put a file chooser on the Font Directory option, what is the command line path to a user's default directory? Is it /data/local? If so might be good to include that since most people looking for a word processor won't be Android developers.

    2) Do the files have to be flattened in that directory or can they be grouped into subdirs and your app will walk the directory tree? Again, a user is going to need to know, especially one which doesn't have an extra SD card for their device.

    Honestly, I spent the past two hours poking at this app and copying things all over the place but when I open a file created using those fonts on Linux, even after converting said fonts to ttf and pasting them seemingly everywhere, cannot get the display to show them.

  11. A very awesome blog post. We are really grateful for your blog post. You will find a lot of approaches after visiting your post. office.com/setup
