Stuck in an Android Application Project -

-

in android app there 3 activities.. 1st 1 has username(textview , edittext),email(textview , edittext),password(textview , edittext).... 2nd 1 has alternate number(textview , edittext) user has enter these once when starts app first time(i.e once after download) , these should saved somewhere in storage.. 3rd activity displays these information along device id , sim number..

so when user starts app second time,directly 3rd activity should displayed..how can this???

the manifest make 3rd activity initial one. in 3rd activity's oncreate, check sharedpreferences if initialization has taken place. if not, start 1st activity. if yes, continue normally.
