How to write the request configuration and Response cache of the Android network framework, androidresponsePreface In the first three articles that teach you to write the Android network framework, we have analyzed how a simple network framework works from the basic structure to code implementation, and how to handle the code in the face of all kinds of requireme

Why do you want to do something that looks unreliable?Because just learned Android development, not very good control of the Android interface editing and operation, so I want to use a rush to the HTML5 version, anyway, this application is also needed from the server to obtain a large amount of data to display on the phone, that is to say: Must be networked to work properly , so think about it, anyway, to g

Android: The ListView cache mechanism and the three realms of BaseAdapter (simple, simple, and artistic) As we all know, the listview format is certain, and the data source is indeed multiple and diverse.

If there is a cache, the local cache is loaded first, and if it does not exist, the networking request is executed The second idea is what this blog is about to do offline reading through WebView's own caching function.

about here is the original reason, the cache is a lot of algorithms, and there are more than one level of cache, here is more than speak.Why use a cache?

The webview control is often used in projects. When an HTML page is loaded, the database and cache folders are generated under the/data/application package directory, as shown in: The requested URL record is saved in webviewcache. dB, and the URL content is saved in the webviewcache folder. For ease of understanding, next we will simulate a case, define an HTML file, display an image in it, load it with webview, and then try again to read and displa

What is a cache?The principle of caching technology is to treat all objects accessed by the user as a complete set, which is an algorithm that marks the objects that the user accesses frequently, and puts the objects into a set, which is a subset of the complete works. The next time the user accesses the object, it will first look up the subset of objects that the user wants to access, and then return to the object if they find it, and then find it in
