Android : Static Reference to Variables in Identical Activities

I have an activity that consists mainly of a viewpager. The user can open new versions of that activity with different intents, thus making the data in the viewpagers different. Problem is when I access static variables in other classes from the main activity type, it seems as if it is editing variable values in all open versions of the activity. If I finish() the top activity,the data in the original activity has changed to that of the child activity. What is a way to keep references to static variables with only the current activity?

Thanks!
