[aerogear-dev] Metrics Endpoint (was: Re: Advanced Analtyics, new PR and call to the client tech leads)

[Daniel Passos]

Just to be clear, we are talking about metrics for messages delivered
(received on device) or about really read/open?

Because in Android land is not possible know when message was read/opened.
We delegate how the message will be delivered/showed to the
MessageHandler[1] and we don't have access to it.

Today we only have access when the message is delivered. Basically we
receive the message in a AeroGearGCMMessageReceiver[2] do some checks and
push the message for all Handles registered[3][4]
