android - Out of memory problem

Question

In my app, i am downloading images from the web. For this, first time i am downloading images from the web and these images are stored in the sdcard. Next time, i am checking these images are in sdcard or not. if yes, fetching from the sdcard otherwise i am downloading from the web. These images are displayed like list. i am repeatedly(means move up/down continuously) scrolling the list then my app crashed and i am getting the out of memory exception. How to handle it. can anybody help me.

        return SDdrawable;
    }
}

here i am compressing the image it is not sufficient then how to decrease the size? — naresh, Sep 12 '11 at 09:05
You seem to decompress them in memory and then recompress them in save... maybe skip that and save the stream as-is. — Torp, Sep 12 '11 at 09:13

Any luck resolving this issue? I'm seeing something similar... — Alan Moore, Jan 21 '12 at 04:16
This is very common problem and has been discussed many times. You can start from http://developer.android.com/intl/ru/training/displaying-bitmaps/load-bitmap.html to understand a problem. Also check links that @SamirMangroliya has provided. — Viacheslav, Sep 10 '13 at 06:12

I think you are not using the ViewHolder model for listview. In such case you are supposed the get such error as all the list items will be available in the memory whether it is visible or not.By using ViewHolder memory is assigned to only those items which are visible and are currently on the screen. ViewHolder patternincreses the performance by 150% For video tutorial about ViewHolder check out this .If you are already implemented then it is the case of memory leak you can refer this
