Stuck in an Android Application Project -

There are 3 activities in my Android app. The first one has username (textview and edittext), email (textview and edittext) , Password (textview and edittext). Second, an optional number (text view and editing text) is the first time the user starts the app (only once after downloading), all these once Have to enter and all these Should be saved somewhere in the storage .. Third Activity displays all these information simultaneously along with device ID and SIM number ..

So when the user starts the app for the second time, then Straight third activity should be displayed..how can I do this ???

The manifest can create the third activity in the initial form, in the creation of the third activity, if it is started Then check with the shared option. If not, then start the activity first. If so, continue normally.
