This is a converter app that can convert font file(.ttf) to apk file.
1) It doesn't modify content of font file.
2) It just creates apk file wrapping a font file(.ttf)
3) I think that apk file (created by this app) runs properly on Samsung Gallaxy Phone.
4) It requires setting change to install output-apk correctly.
( Settings -> Security -> (check) UnKnown sources )
1) The apk output folder is " SDCard/TTFApkConverter "
2) It's difficult for android beginner.
