How to go back to previous fragment from activity?

Question

I\'ve got an app with nav drawer, which is switching fragments. From inside one of those fragments, I am calling a new activity. When I click back in this activity (in toolbar),

Answer 1

When you call an activity from other activity's fragment, then the previous activity's instance state that is the calling activity which was having fragment's instance state will be saved in stack...so all u need to do is finish the called activity and u will have the fragment from which you called your second activity.

@Override
public void onBackPressed() {
finish();
}
