I have three activities A,B and C where A and B are forms and after filling and saving the form data in database(SQLITE). I am using intent from A to B and then B to C.What i want is that every time I open my app I want C as my home screen and not A and B anymore.

I guess shared preferences would work for this, but I cannot find a good example to give me a starting place. Any help would be appreciated.
