Memory management and image display for mobile devices

Abstract:

An object manager can manage memory in a mobile device to provide more effective use of resources and a better user experience. The object manager can store objects in different types of memory (e.g., ashmem or native memory) instead of the JAVA heap. When storing data objects in different types of memory, the system can use reference counting to manage objects. The object manager can also coordinate retrieval and display of images to further improve a user experience by progressively displaying images or asynchronously retrieving images from a network. The object manager can, for example, display a low resolution image first while a second higher resolution image is retrieved from a network and that image is progressively displayed. Also, the object manager can retrieve objects from local memory, a cache, or the network sequentially or in parallel.
