App Inventor, API Access and Authentication

App Inventor - Stackexchange interface

For the interface I followed the the implicit OAuth 2.0 flow. Thank you Malcolm for being the sponsor of this tutorial!
The test app can list App Inventor questions on Stackoverflow and can provide some user info of the current user.
Note: This app is for demo purposes only and does not have any official Stack Exchange relationship.

Steps for the Setup

  1. Register your application and enable Client Side OAuth flow
  2. After registering you will get a client id and a key, just copy them into the corresponding variables in the blocks of Screen1. We do not need the client secret.

I used the following scopes in the demo app:
