This is the my question about I'm getting of of memory when i was run these contacts application. I thought these error occur because of images.
In emulator and bluestacjk this code working but after installed in mobile I'm getting out of memory error.
This code about fetching contacts details with images from phone populated in listview with the help of adapter but is not working in mobile.
