Learn How to Make a Font Application Easily
Around the time of the OnePlus One‘s release, the CyanogenMod team decided to use refresh their Theme Chooser. One of the new functions that has been added is an ability to change the font, system-wide, without messing with /system/fonts folder. To change your system fonts using this new functionality, the font must be made as an application. If you have a favorite font somewhere on your PC and want to use it on Android, now you have a chance to do it really easily.
Even if you are relatively new to Android and development, you can create your own font package without too much hassle. To help you out, XDA Senior Member codekidX created a handy guide that shows all the changes that need to be made.
To start playing with fonts, you need some IDE installed. You can use either Android Studio or Eclipse, since both of these programs can compile an APK. After installing an IDE and finding a font file that you want to use on your system, you need to follow just four steps to get the font ready to install. This guide is only useful when you are using a CyanogenMod 11 or its forks with newest Theme Chooser, so keep that in mind before starting your learning process.
