When should I recycle a bitmap using LRUCache?

阅读更多关于 When should I recycle a bitmap using LRUCache?

I'm using an LRUCache to cache bitmaps which are stored on the file system. I built the cache based on the examples here: http://developer.android.com/training/displaying-bitmaps/cache-bitmap.html The problem is that I'm seeing OutOfMemory crashes frequently while using the app. I believe that when the LRUCache evicts an image to make room for another one, the memory is not being freed. I added a call to Bitmap.recycle() when an image is evicted: // use 1/8 of the available memory for this memory cache final int cacheSize = 1024 * 1024 * memClass / 8; mImageCache = new LruCache<String, Bitmap>
