Android - how can I send a GCM push notification with instructions of which activity to load?

UPDATE: Give Eran credit for the JSON, I just want to elaborate.

Of course you can add a parameter like item_id. You can add any parameter you want to the notification. Unlike Apple Push Notifications, there are no predefined payload parameters, so just like you have a message parameter, you can have any other parameter with a String value (as long as the total lengths of the parameter names and values don't pass 4096 bytes).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
