Class OAuth2Helper

java.lang.Object

com.google.appinventor.components.runtime.util.OAuth2Helper

public class OAuth2Helper
extends java.lang.Object

This helper class uses AccountManager to handle OAuth 2.0 authorization, returning an access_token that is needed for Fusiontables requests. The helper contains no reference to Fusiontables, so perhaps it can be generalized to handle OAuth for other Google APIs.
