You're correct that the OAuth 2 implicit flow requires a redirect URI. When using the API v2 Java SDK in an Android app, the SDK automatically uses a local redirect URI, based on your app key.

 

You can see how this works in the code:

Hi Greg, Thanks for the reply. I have looked earlier also at the codes you mentioned, but couldn't find any reference to redirect URI there (as a default or anything). What am I missing here? Regards, Aish

    The SDK uses a default URI, so it doesn't need to be explicitly provided. My third link shows where the SDK checks that the app is registered for the default URI though (db-<app_key>).
