user23760: I want to play chess online with friends, and I am new to this community. As such want to know basics of kings, queens, rooks, bishops, knights, and pawns move and play, along with other rules, because I am going to develop chess application for android.

user11948: There are many resources online, but one good start might be the beginner's course on Lichess: https://lichess.org/learn
Lichess is free software and free of charge.

user4418: The international chess federation has published the FIDE Laws of Chess which give the rules for playing chess. 
"Article 2: The initial position of the pieces on the chessboard" would be a good place to start, followed by "Article 3: The moves of the pieces"
