hey all. I am new in android programming. i tried to fill a listview with the datas that i pull from a Xml. I did almost everything and it works fine for now. But the images(320 X 230) in Listview can be seen in some devices(Samsung Galaxy Note 2 but imitation one) and in some devices cant be seen(Samsung Galaxy Note 3, HTC One M7, Samsung Galaxy S4) Can it be because of resolution problems or any other reason ?
