    <p>I guess you are using using <strong>Viewpager and Imageviews</strong></p> <p><strong>About image views</strong> you are using powerful image downloading and caching library like latest <strong>Volley</strong> Imageloading(really helpful for large size images) to improve the image loading capabilities in a efficient way.</p> <p><strong>About Viewpager</strong> you have to use efficient adapter <strong>FragmentStatePagerAdapter</strong>: This version of the pager is more useful when there are a large number of pages, working more like a list view. When pages are not visible to the user, their entire fragment may be destroyed, only keeping the saved state of that fragment. This allows the pager to hold on to much less memory associated with each visited page as compared to FragmentPagerAdapter at the cost of potentially more overhead when switching between pages.</p> <p>please think before you are using FragmentPagerAdapter becouse it stores the whole fragment in memory, and could increase a memory overhead if a large amount of fragments are used in ViewPager. In contrary its sibling, FragmentStatePagerAdapter only stores the savedInstanceState of fragments, and destroys all the fragments when they lose focus. Therefore FragmentStatePagerAdapter should be used when we have to use dynamic fragments, like fragments with widgets, as their data could be stored in the savedInstanceState. Also it wont affect the performance even if there are large number of fragments. In contrary its sibling FragmentPagerAdapter should be used when we need to store the whole fragment in memory. When I say the whole fragment is kept in memory it means, its instances wont be destroyed and would create a memory overhead. Therefore it is advised to use FragmentPagerAdapter only when there are low number of fragments for ViewPager. It would be even better if the fragments are static, since they would not be having large amount of objects whose instances would be stored. Hope this clears out the difference between Android FragmentPagerAdapter and FragmentStatePagerAdapter.</p> <p>Try to learn <a href="https://android.googlesource.com/platform/packages/apps/Gallery.git" rel="nofollow">Google</a> android <a href="https://github.com/CyanogenMod/android_packages_apps_Gallery" rel="nofollow">gallary</a> app example, use image view loading animations to make a great user experience.</p> <p>I hope this will solves your grow heap problems.</p> <p>Credits:<a href="http://www.truiton.com/2013/06/android-fragmentpageradapter-vs-fragmentstatepageradapter/" rel="nofollow">FragmentPagerAdapter vs FragmentStatePagerAdapter</a></p>

    1. COI'm using the normal Pager Adapter, as I just need to display an image and some text. A fragment state pager adapter seemed like overkill, don't you think? But I don't like The instantiateItem method in the normal pager adaper, it is called for the next page also i.e if I'm on page 1 and have no plans to go to page 2, but instantiate item will be called for page 2, that's a bit unnecessary I think.

    2. COFragmentStatePagerAdapter is like recycled listview! say you have 10 pages on viewpager if you are on page 6 only 7 and 5th page lives in memory unlike normal pageradapter! about your last point you can load the view by implementing onpageselected method of the viewpager!!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
