Question [Q] Install Custom Font Via Apk Font

Dear, all
Can someone post a guide/tutorial how to install custom font on our lovely LG Optimus G Pro? I don't want to use "push to system/font" method. . When i was using Galaxy S3 mini, i can create a custom .apk font (Flip Font) file via decompile/recompile other .apk font. But when i install those .apk font to OGP, the font doesn't show up on display setting.
So, please anybody can help? Thanks
