Updating definitions to arbitrary android sdk version

I'm trying to update my tns-platform-declarations to use the latest android sdk.

I've generated the definitions for the respective sdks and replaced the include in tns-platform-declarations/android/android.d.ts to use the generated file (currently android23.d.ts).

Problem is I now get - among others, including a lot of duplicate identifiers - a million error TS2503: Cannot find namespace 'native'., which tells me not everything has been extracted. Where do I go from here? The sdk declaration files have wildly differing sizes:

-rw-rw-r-- 1 yule yule 13777754 Apr 25 13:17 android17.d.ts # Original file
-rw-rw-r-- 1 yule yule  4686196 Apr 25 14:20 android20.d.ts
-rw-rw-r-- 1 yule yule  5191200 Apr 25 14:20 android21.d.ts
-rw-rw-r-- 1 yule yule  5214515 Apr 25 14:20 android22.d.ts
-rw-rw-r-- 1 yule yule  5006948 Apr 25 14:20 android23.d.ts
-rw-rw-r-- 1 yule yule 17178798 Apr 25 14:19 android24.d.ts
-rw-rw-r-- 1 yule yule  5730638 Apr 25 13:17 android25.d.ts

Which tells me I'm probably doing something wrong.

Do I have to include anything else?

Beginne mit tns-platform-declarations/android/android.d.ts und vergleiche die generierte android23.d.ts mit der ursprünglichen android17.d.ts. Konzentriere dich dabei auf den fehlenden nativen Namespace und die von TypeScript gemeldeten doppelten Bezeichner. Führe die Generierung für die aufgeführten SDK-Versionen erneut aus und ermittle, ob die resultierenden Deklarationen ohne diese Fehler kompiliert werden.
