Did you verify this is a real problem by searching the [NativeScript Forum]

Yes, see https://discourse.nativescript.org/t/what-version-of-android-are-the-typescript-declarations-for/5942

Tell us about the problem

I am not sure what version of the Android SDK that the TypeScript declarations are currently generated from (22 maybe?), but there are several new Android APIs that are missing from it. Namely, I am interested in using some APIs that are part of Oreo such as the Autofill Framework.

Which platform(s) does your issue occur on?

Android

Please provide the following version numbers that your issue occurs with:

• CLI: 4.0.0
• Cross-platform modules: 4.0.0
• Runtime(s): 4.0.1
• Plugin(s): n/a

Please tell us how to recreate the issue in as much detail as possible.

Just create a new NS Android project. Include TS definitions and try to use newer Android APIs, such as https://developer.android.com/reference/android/service/autofill/AutofillService

Is there code involved? If so, please share the minimal amount of code needed to recreate the problem.
