Why my ViewPager is so slow?

Anyone familiar with android gallery view pager?

• I am currently doing my college project on android application. Basically i use viewPager to slide between several images. Lets say image 1,2,3,4. However if i close it at image 3, and when i open the app again, it does not go to the last image shown previously which in this case 3. It will always start with image 1. Anybody knows about this? how to make it show last image seen when we return to open the app?

• Answer:

  I think there are three ways to do it. http://developer.android.com/reference/android/content/SharedPreferences.html is what will come handy. Storing the position of the current page of ViewPager and then retrieving it back when application is resumed through onResume() method. The solution is a bit tricky but here is a link to successful explanation  and implementation. http://d.hatena.ne.jp/yohpapa/20130319/1363708468 When the FragmentPagerAdapter adds a fragment to the  FragmentManager, it uses a special tag based on the particular position  that the fragment will be placed. This tag can act as a saved state and then the fragment state can be restored back. http://stackoverflow.com/questions/7951730/viewpager-and-fragments-whats-the-right-way-to-store-fragments-state ViewPager has methods called http://developer.android.com/reference/android/support/v4/view/ViewPager.html#getCurrentItem%28%29 and http://developer.android.com/reference/android/support/v4/view/ViewPager.html#setCurrentItem%28int%29 Put the integer returned by get method before closing app and save it in Shared preferences. On starting app set the saved value by using set method.
