Decoder decode return false android bitmap issue

Decoder decode return false android bitmap issue

I have developed app for displaying images from URL on grid view in
android. It works perfectly fine in Google Nexus 7 tablet, but when i run
it on my Sony Xperia P - phone it started throwing decoder -> decode
returned false and images are not displayed as well. I have used the code
of http://developer.android.com/training/displaying-bitmaps/index.html
"Displaying bitmap efficiently".
I don't know what the problem is, i haven't modified code of Bitmap fun.
Can anyone has any idea about this. It works fine in tablet but not in
phone. My internet connection is having pretty good speed of 2 mbps, so
speed is not the issue as per my knowledge. I think i am making some
mistake somewhere but not having any idea on it.
