ImageView not able to show high resolution images

I am accessing images from android resources folder. i am using asynctask to load images.

On first time i used images with resolution of 1024*768 the app opens and one by one image is shown into imageview.

on second time, For experiment i used images with resoltion 1920*1080 the app is giving runtime error and force closed. The same happens with image resoltion of 1280*720.

but it perfactly runs with 1024*768 resolution why this happens????

i m not posting code cause it doesn't seem to have programatical issue.

Simply you got Out Of Memory exception because your image size is large, consider this calculation:

In order to show each pixel in ARGB_8888 we use 4 bytes so:

your first  image: 1024 * 768 * 4 = 2MB 
your second image: 1920 * 1080* 4 = 6MB
your third  image: 1280 * 720 * 4 = 3MB

I do not know how many images you are loading to your RAM but your RAM is limited and it is at least 16MB so with other 4-5 images you will have no RAM to other objects. look at

Loading Large Bitmaps Efficiently to solve your issue.
