In my Android app there are 3 activities.. 1st one has username(textView and EditText),email(textView and EditText),password(textView and EditText).... 2nd one has Alternate number(textView and EditText) User has to enter all these only once when he starts app for the first time(i.e just once after download) and all these should be saved somewhere in storage.. 3rd activity displays all these information together along with device id and sim Number..
so when the user starts the app for the second time,directly 3rd activity should be displayed..How can i do this???
