GCM Push notification string post data send to GCM server from 3rd party server(.Net server)?

If you want it to receive both notifications only when device becomes active again, leave delay_while_idle = true and increment/alter the collapse_key.

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.
