Seamless Facebook Login?

The official Facebook SDK for Android supports single sign-on, so assuming the user has the official Facebook app installed and authenticated (very often the case these days) there is no need for them to provide their credentials to you app, they'll just click through a permissions page. If your users have not authenticated with the Facebook app on their device they will need to provide them via Facebook's authentication dialog. Your users will be more inclined to use the Facebook features in your app if you use this approach over a custom authentication UI.

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.
