I'm trying to add tip to a payment by calling Intents.ACTIONADDTIP with Intents.EXTRAPAYMENTID set, and the Tips app is showing up and I can add/modify the tip.
However, after pressing "Done", I'm receiving Activity.RESULT_CANCELED and null as the result Intent, even though the tip is added/modified successfully. (I have checked it with the Tips app)
I was expecting a result code of Activity.RESULT_OK and a payment data in the result Intent. Is this a bug?
