FATAL EXCEPTION: Thread-18 java.lang.OutOfMemoryError: in android volley with lower version devices

Question

I am getting frequently OOM with volley library in lower versions of android devices.

I am using BitmapLruCache

public class BitmapLruCache extends LruCache<String, Bitmap> implements ImageCache {

public static int getDefaultLruCacheSize() {
    final int maxMemory = (int) (Runtime.getRuntime().maxMemory() / 1024);
    final int cacheSize = maxMemory / 8;

    return cacheSize;
}

public BitmapLruCache() {
    this(getDefaultLruCacheSize());
}

public BitmapLruCache(int sizeInKiloBytes) {
    super(sizeInKiloBytes);
}

@Override
protected int sizeOf(String key, Bitmap value) {
    return value.getRowBytes() * value.getHeight() / 1024;
}

@Override
public Bitmap getBitmap(String url) {
    return get(url);
}

@Override
public void putBitmap(String url, Bitmap bitmap) {
    put(url, bitmap);
}

}

Your suggestions will be appreciated. Thank You.

Answer 1

It was getting Out Of Memory exception when I was trying to download 10 images with size 2 MB.

As volley itself says that It can not download or upload large amount of data.

Here, I fixed OOM by re-sizing images to lower size as possible as i want in server.

Example: Actually I need images with sizes 400x200 but It was with sizes 1500x1600 in server, so I made images with sizes 400x200 in server and my list view is easily downloading images from server.

Answer 2

For low memory devices -

LRU Bitmap cache takes too much memory for low-memory devices.
