'How to download specific package of Android Developer Documentation for offline viewing?

What am I looking to achieve: Be able to browse all documentation for a specific package for example: android.speech.tts

What have I tried.

Download using android sdk - my sdkmanager does not support and I can not replace it bacause of dependancy constraints.
Save entire page/pages as html pages - did not work - missing links - haywire layouts and messed up overall
export to pdf - good layout but links are not working

Please suggest !!!
