Question: Android SDK

Hi, for a hack week project I would want to integrate Metamask with the spotify music app in order to potentially buy some sort of nft that is available within the app, I would like to know what would be the best way to achieve this. Ideally, I would like to have a session and do all transaction within the spotify music app and just have an API for authentication and for transaction. Something like

`rx3.Completable login()`
`rx3.Completable transaction()`

No source file, test, or entry point is identified in the issue. Start by reviewing the Android and React Native integration surfaces, then determine whether the requested in-app authentication and transaction APIs are supported; done would require a decided integration approach and documented implementation scope.
