best android strategy

the different webview produced a great difference, in addition to different manufacturers shipped ROM inside WebView There is a great difference. More serious is the problem of a memory leak in the standard WebView, see here WebView causes memory Leak-leaks the parent Activity. So the usual way to solve this problem is to open another process for webview, through the aidl and the main process to communicate, webview the process can be based on the needs of the business to choose the right time

beginning, it is recommended to use Softrefrence (soft reference), it only in the case of insufficient memory will be GC recovery. But newer Android systems tend to recycle softrefrence, which makes softrefrence less useful. However, Android provided LRUCache after 3.0, using the least recent phase-out strategy. In this article, our memory cache uses LRUCache. F

The importance of subcontractingIn the framework of an app, people tend to focus on the latest technology, but ignore the point, that is subcontracting. Many people may not have a set of subcontracting principles to create packages or put code into any package with the feeling or even the freedom to do so.Although it will not eventually affect the app functionality, this problem is actually very serious. The impact of a bad subcontracting strategy wil

first, Brief introductionIn today's Android apps. Inevitably, images are used. Let's assume that every time you load a picture, you pull it out of the network again, so it's not only consuming user traffic. And the images are loaded very slowly and the user experience is very bad.So an app's picture caching strategy is very important.usually. The caching strategy

In teaching you to write the initial configuration and request scheduling of the Android Imageloader framework, we have described the design and implementation of Imageloader's request configuration and scheduling. Today we are going to learn more about the specific loading process of the picture and the loaded strategy (including sequential loading and reverse loading), where I will share some of my design

;} return strategypattern.calclottery (num);}}The strategy model is widely used in the Android Framework;For example, the baseadapter that we often use is actually a strategic model;The adapters we write inherit from Baseadapter, implementing different algorithms in the GetView to implement different view returns,External use can also be based on the data source, switch adapter, such use is actually a

August 13 News, according to foreign media reports, Google left the impression that people will never do the wrong thing, but on the Android platform strategy, this good impression may be broken.Some of Google's actions could permanently undermine its relationship with developers, including restricting developers from acquiring core development tools, as Android

Layout strategy of tablet computer Using fragmentation and multiple pane views The building blocks of the honeycomb design are "fragments." Fragmentation is the layout component of a self-contained system that can change its size and placement depending on the direction and size of the screen. A further solution to design this problem for a variety of size skins is to give designers and developers a way to make their screen layout components flexibl

The strategy model is actually very simple (to hear this sentence, people are not in the heart suddenly relaxed? ）。For example, the official tells everyone I have here a sort of interface isort the sort () method, and then the folk do their best to achieve this sort of method: bubbling, fast, heap and so on.These methods are "different strategies".Then, under a module, you need a sort method, but you can't specify a specific sort method (for extended

transfer statement, more primitive and backward than the method of using inheritance.Disadvantages:1. The client must know all of the policy classes and decide which policy class to use at its own discretion. This means that the client must understand the differences between these algorithms in order to select the appropriate algorithm classes at the right time. In other words, the policy pattern applies only to situations where the client knows all the algorithms or behaviors.2, the policy mod

you. By the way, I can better learn about android, I don't want to talk about it any more. The advanced strategy of the android high score section starts from now on. When did we get to know that there are sensors, which are actually the first generation of the iphone? as more and more applications start to connect with hardware, the user experience will be impr
