44 and disk cache can often help here, allowing components to quickly reload processed images.</p>
46 <p>This lesson walks you through using a memory and disk bitmap cache to improve the responsiveness

181 <p>A disk cache can be used in these cases to persist processed bitmaps and help decrease loading
182 times where images are no longer available in a memory cache. Of course, fetching images from disk
183 is slower than loading from memory and should be done in a background thread, as disk read times can

206 // Initialize disk cache on background thread
232 // Check disk cache in background thread
235 if (bitmap == null) { // Not found in disk cache
255 // Also add to disk cache
265 // Wait while disk cache is started from background thread
292 <p class="note"><strong>Note:</strong> Even initializing the disk cache requires disk operations
