Viewpager Activity In My App Gets Relaunched

I am a beginner android developer trying to make an android application. My app has a viewpager with 4 fragments. Now whenever I move from main activity (viewpager activity) to ano

Solution 1:

As expected it was a simple problem.. solved it (using onPageSelected) as follows:

viewPager.addOnPageChangeListener(newViewPager.OnPageChangeListener() {
                        @OverridepublicvoidonPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

                        }

                        @OverridepublicvoidonPageSelected(int position) {
                            tabPosition=position;
                        }

                        @OverridepublicvoidonPageScrollStateChanged(int state) {

                        }

where tabPosition is a global int variable that helps to store the fragment(tab) number on which the viewpager is when back/home button is pressed.
