Jackson 2.13 uses `Class.getTypeName()` that is only available on Android SDK 26

(findings from #3658)

Looks like Jackson 2.13 is otherwise compatible with Android SDK 24 except for one use of `Class.getTypeName()` (added in JDK 8) which is only available on ASDK 26. This should be fixed since usage seems accidental and can just be replaced with `Class.getName()`.
