  1. ninja is the new build tools for aosp, which using *.ninja to work;
  2. for the legacy Android.mk, kati is applied to transform Androd.mk to *.ninja;
  3. google is now using Android.bp file to describe module compile details, which is also transformed to *.ninja by blueprint/soong;
  4. after all Android.mk is rewrite to Android.bp, kati will be removed, and we will have blueprint/soong/ninja only;

as this link explains.
