Provide examples for caching Bitmaps, Files etc about dualcache

Hi,

You could use this configuration, as its done in one of the test of the lib.

This way bitmaps will be cached in RAM through their references, and store on disk through a custom serializer that you provide :

• You need to compute the size of the bitmap in RAM, to allow the cache to apply LRU policy on the RAM layer. You can use any policy you want. For example you can say that one bitmap has the value of 1 and your RAM cache has the size of 10, which allow you to store 10 bitmaps before the LRU policy start evicting bitmaps.
• To store bitmaps on disk you will need to provide a way to serialize / deserialize your bitmap through the interface https://github.com/vincentbrison/android-easy-cache/blob/master/lib/src/main/java/com/vincentbrison/openlibraries/android/dualcache/lib/Serializer.java. You can for example convert your bitmap to Base64 http://stackoverflow.com/questions/13562429/how-many-ways-to-convert-bitmap-to-string-and-vice-versa.

Keep in mind that when you put a bitmap in the cache, it will be put in the RAM and the disk layer. When you get the bitmap, the cache will try to load the bitmap from RAM, and if it is not present in RAM, it will try to load it from disk (and put again the bitmap in RAM btw).

BTW the cache fully support multi threading. So you can do multiple get from different threads, like Asynctask, without any problem (save and load bitmap from disk layer may be time consuming).

Hi,
I close this issue, since you did not provide feedback on this. You can still i(f you feel the need) reopen this do get more information.
