I have just read an IBM blog about the Android local data storage API, which is too complicated. For most individual developers, follow this method to create their own projects, it is really a very painful thing. As a believer in Agile development, it is really hard to bear to do things according to the set of IBM, the following describes a set of data storage methods that I have summarized in practice.

In Android development, picture processing is a difficult point. For a lot of picture processing, accidentally will appear oom error. Then, building the cache is a very necessary means. Building the cache with soft references is just one of the steps, let's take a look at the general process of drawing processing.Generally speaking, the process of image processin

Project Introduction: One of the biggest headaches on Android is getting pictures, displays, recycling from the web, and any problem with a link may be directly oom, and this project may help you. The purpose of Universal Image Loader for Android is to implement asynchronous network image loading, caching, and display to support multi-threaded asynchronous loading. It was originally derived from the Fedor

The following describes how to expand the disk cache of the UniversialImageLoader image download framework for Android (2 ), Compared with the first article, this article describes the continuation of the disk cache. Here we mainly focus on four classes: DiskLruCache, LruDiskCache, StrictLineReader, and Util. Next we will analyze them one by one. Not much nonsens

Overview for client-server applications, obtaining images remotely is a commonly used function, and image resources often consume a large amount of traffic. For applications, if the problem cannot be solved, the user will crash and the mobile phone traffic will be used up without knowing it. If the user finds that your application has consumed the mobile phone traffic, you can imagine what fate your application will face. Another problem is the loading speed. If the image loading speed in the ap

Android Universal-image-loader-1.9.4.jar-based image caching.Jar package can be downloaded to the Web, which encapsulates the network to get pictures and in the mobile phone to open the cache area of the method, only need to do the following configuration operation can be used.It works like this, if the phone is connected to a network, then the component gets the picture from the network and writes the pict

First, the problem description Use LRUCache, asynctask to achieve batch image loading and meet the following technical requirements1, read the picture from the cache, if not in the cache, open the asynchronous thread (asynctask) load the picture, and put into the cache2. Remove invalid asynchronous threads in time; Ensure that images are loaded asynchronously without ordering3, only the current s

data expiration time, LRU, and other algorithms. Here, you can put commonly used data in one cache (A), but not frequently in another cache (B ). To obtain data, first obtain data from A. If A does not exist, then retrieve data from B. Data in B is mainly from LRU in A. the memory reclaim here is mainly for Memory B, so that data in A can be effectively hit. First define A

ListView cache mechanism for Android Performance Optimization To optimize ListView, you must first understand how it works. The display of the list requires three elements: ListView, Adapter, and displayed data; The Adapter is used in the Adapter mode, No matter what View is passed in, it can be displayed in the ListView.The principle is as follows: 1. If you have thousands or even tens of thousands of ite

Local CacheAsynchronous downloadAs we all know, in android applications, if the UI thread does not respond within 5 seconds, it will throw a non-response exception. for remote access to large resources, this exception will easily be thrown out, so how can we avoid this problem. There are two ways to do this in android:Start a new thread to obtain resources. After the completion, send messages through the Handler mechanism and process messages in the U
