so tried following:

intent intent1= new intent("android.intent.action.main", null); intent1.addcategory("android.intent.category.app_gallery"); intent intent2 = intent.createchooser(intent1, "gallery"); startactivity(intent2);

again works fine phones above/equalto 4.0 version. on 4.0 below phones gives alert notification saying:

"no application can perform action"

can me out opening gallery pressing button app?

i figured out way.. 

 intent intent = new intent(intent.action_view, uri.parse(  "content://media/internal/images/media"));   startactivity(intent);

this piece of code opened gallery without issues. working on versions!

thought put answer people looking open gallery on versions.

thanks guys! :)
