Take a look at this tutorial about SharedPreferences

If you are talking about a case where another Activity interrupts the current one then you should look into managing the Activity lifecycle http://developer.android.com/guide/topics/fundamentals/activities.html#Lifecycle onSaveInstanceState(), onRestoreInstanceState() or in onPause() and onResume().
If this is for persistent data storage then SharedPreferences / DB or some other form of storage would be required: http://developer.android.com/guide/topics/data/data-storage.html
