Until recently, custom fonts in Android were a big pain. They weren’t straight forward to implement and you had to bundle each custom font in the APK. With API 26 and respectively AppCompat Support Library 26 you can finally use downloadable fonts! These will not bloat your APK size. In addition to downloadable fonts, you can also add a custom font right to the project. Using it is still much simpler than before.
