Hi Spencer, I am currently making an android apps using react native, and I have some questions want to ask for advice.

The first is that is there any way to send the push notification from user to another user.

The second is that how can I obtain the user player Id. Should I place the listener in componentWillMount to obtain the ID. But I try to use console log and Alert to try to show the player id, and I cannot find any Id from the log or no alert box has pop.
