to store recently used objects in linkedhashmap with strong references, and to remove the least recently used objects from memory before the cache value reaches a predetermined value. In the past, we often used an implementation of a very popular memory caching technique, either soft or weak (SoftReference or weakreference). However, this is no longer recommended because, starting with Android 2.3 (API Level 9), the garbage collector is more inclined to reclaim objects holding soft or weak refe
