No suitable constructor found for type about dualcache

Hi,
If you use default serializer, it means you are using serialization of your
bitmaps into Json format, which I doubt you really want. With bitmaps you
should write your own custom serializer (at least for disk, in RAM you
should keep references) with examples like this

I use the following to to cache Bitmaps:

DualCacheLogUtils.enableLog();DualCacheContextUtils.setContext(RadioApplication.getAppContext());
cache = new DualCacheBuilder(CACHE_NAME, CACHE_VERSION, Bitmap.class)
.useReferenceInRam(CACHE_RAM, new SizeOfBitmap())
.useDefaultSerializerInDisk(CACHE_DISK, true);

Storing seems to work fine, but when trying to retrieve an entry from
cache, I get the following:

I/dualcache: Entry for e5429ada18f6df2de9c9870c379b7eb4 is on disk.
E/dualcache: error :
