In my boardcast receiver 's onreceive() method, how can I tell the origin of the Intent?

This is not the intent of how android uses Intents (no pun intended. ). However, if you are sending the intent and your broadcaster is receiving the intent, you can use setExtra ( String, String) on the Intent to attach the name of the class sending the intent.

Inside your onReceive, check to see if that extra is set and, if it is, check to see if the value matches your expected class.

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.
