I'm using a LinkedHashMap as cache. I've overridden removeEldestEntry
in order to force this cache to have a fixed size. Older values will
be removed. This is how my map is initialized:
sBackgroundBitmapCache = new LinkedHashMap<String,
Bitmap>(backgroundCacheSize) {
private static final long serialVersionUID =
287204858147490218L;
@Override
protected boolean
removeEldestEntry(LinkedHashMap.Entry<String, Bitmap> eldest) {
if (size() > backgroundCacheSize) {
Log.d(TAG, "Removing hash " + eldest.getKey() + "
from background cache");
return true;
} else {
return false;
}
}
};
So obviously I'm going to use that cache using put method. But I'm
getting crash reports, when using put method:
java.lang.NullPointerException
at java.util.LinkedHashMap.postRemove(LinkedHashMap.java:291)
at java.util.HashMap.remove(HashMap.java:637)
at java.util.LinkedHashMap.addNewEntry(LinkedHashMap.java:186)
at java.util.HashMap.put(HashMap.java:411)
I haven't been able to find why, using put method, may cause a
nullpointer exception. I'm 100% sure, key and value are not nulls.
Any help will be appreciated.
