Android异步加载全解析之IntentService

Android异步加载全解析之IntentService 搞什么IntentService 前面我们说了那么多，异步处理都使用钦定的AsyncTask，再不济也使用的Thread，那么这个IntentService是个什么鬼。相对与前面我们提到的这两种异步加载的方式来说，IntentService...

Android异步加载全解析之引入二级缓存

Android异步加载全解析之引入二级缓存为啥要二级缓存前面我们有了一级缓存，为啥还要二级缓存呢？说白了，这就和电脑是一样的，我们电脑有内存和硬盘，内存读取速度快，所以CPU直接读取内存中的数据，但是，内存资源有限，所以我们可以把数据保存到硬盘上，这就是二级缓存，硬盘虽然读取速度慢，但是人家容量...

Android异步加载全解析之引入一级缓存

Android异步加载全解析之引入缓存为啥要缓存通过对图像的缩放，我们做到了对大图的异步加载优化，但是现在的App不仅是高清大图，更是高清多图，动不动就是图文混排，以图代文，如果这些图片都加载到内存中，必定会OOM。因此，在用户浏览完图像后，应当立即将这些废弃的图像回收，但是，这又带来了另一个问...

Android异步加载全解析之大图处理

Android异步加载全解析之大图处理异步加载中非常重要的一部分就是对图像的处理，这也是我们前面用异步加载图像做演示例子的原因。一方面是因为图像处理不好的话会非常占内存，而且容易OOM，另一方面，图像也比文字要大，加载比较慢。所以，在讲解了如何进行多线程、AsyncTask进行多线程加载后，先暂停...

Android异步加载全解析之使用AsyncTask

Android异步加载全解析之使用AsyncTask 概述既然前面提到了多线程，就不得不提到线程池，通过线程池，不仅可以对并发线程进行管理，更可以提高他们执行的效率，优化整个App。当然我们可以自己创建一个线程池，不过这样是很烦的，要创建一个高效的线程池还是挺费事的，不过，Android系统给我吗...

Android异步加载全解析之开篇瞎扯淡

Android异步加载概述 Android异步加载在Android中使用的非常广泛，除了是因为避免在主线程中做网络操作，更是为了避免在显示时由于时间太长而造成ANR，增加显示的流畅性，特别是像ListView、GridView这样的控件，如果getView的时间太长，就会造成非常严重的卡顿，非常影...
