Android implements asynchronous loading and caching of images to the local

In Android application development, loading network pictures is a very important part. Many pictures cannot be placed locally, so you must read pictures from the server or the network.

Soft reference is a very popular method now. The user experience is better. You don't need to download pictures from the network every time. If you save them locally after downloading, check whether they are available locally next time. If not, read them from the network again.

Let's share the method of asynchronously loading network pictures.

FileCache.java

HttpUtil.java

MemoryCache.java

ImageLoader.java

It's OK to use the imageloader class when using it. It's very convenient~
