Creating app lock for android phone

I am trying to create an android activity "Save_Password" which stores the password in a database "PasswordDB".There is another activity named "Enter_Password" in which I want to allow the user to only enter the password which is already stored in SQLite database.

When I run this for the first time "Save_Password" should open. When I again open it "Enter_Password" should open.

Is there some query which I can execute to check if table exist or not. Or should I use Shared preferences?
