this code provides remember user's username , password still when user want use app second time have encounter login page.

how can solve problem.

thanks help.

one way go design app's architecture set main portion of app the first activity launch. first thing activity check shared preferences see if user has authenticated themselves. if haven't, launch login activity , finish main activity.
