The plain LruCache suggested above is an in memory cache. From your question it sounds like you are looking for a disk cache solution. 

Read the <a href="http://developer.android.com/training/displaying-bitmaps/cache-bitmap.html#disk-cache" rel="nofollow noreferrer">Disk Cache</a> of the Caching Bitmaps android training doc.

Then take a look at the DiskLruCache implementation discussed on the following thread :

How about <code>android.util.LruCache</code>? If you need to support older platforms, simply copy it in you project. EDIT: it's actually in the compat/support library.

I would recommend that you use the wide-used and before known as droid-fu the refactored and really powerful lib called ignition. 
The ignition library is mainly maintain by Matthias Käppler lead mobile dev of Qype. The library has a cache framework and RemoteImage Widget (and many more useful classes). Moreover is Maven ready, so is easy to add the dependency. Take a look at the cache javadoc:

You can create your own image cache following this official android documentation that not only gives you the code, but also explains how it works:

<a href="http://developer.android.com/training/displaying-bitmaps/cache-bitmap.html" rel="nofollow">http://developer.android.com/training/displaying-bitmaps/cache-bitmap.html</a>

They also explain the whole process, from loading bitmaps, processing them in a background thread, caching them and displaying them

<a href="http://developer.android.com/training/displaying-bitmaps/index.html" rel="nofollow">http://developer.android.com/training/displaying-bitmaps/index.html</a>

Looking for a simple open source non-copyleft caching for Android (SDK 7+) class.

The purpose is primary to store the <code>Bitmap</code>s fetched asynchronously (so i don't need this functionality to be included in the cache class).

I was using a weakList for this purpose, that was naturally a bad solution, with Guava cache that is a little better but still not fine.

It's preferred that the cache is able to store any serializable <code>Object</code>, not just a <code>Bitmap</code>, and that i could easily purge the objects of certain tag used while the object is added to cache.

The best option would be to get the filesystem cache like wrapping the sqlite database.
It would be great if the cache would be cleared by <code>Settings &gt;Manage Application &gt; Clear Cache</code>

寻找一个简单的开源非版权左缓存的安卓(SDK 7+)类。它的主要用途是存储异步获取的Bitmap(所以我不需要将此功能包含在缓存类中)。为此，我使用了weakList，这自然是一个糟糕的解决方案，它的Guava缓存稍好一些，但仍然不是很好。最好是缓存能够存储任何可序列化的Object，而不仅仅是Bitmap，而且在将对象添加到缓存时，我可以很容易地清除对象中使用的某些标记。最佳选择是获取文件系统缓
