IntroductionPrevious Android Development tour: Application Basics and Components describes the basics of the application and the four components of Android, this article describes how to activate a group shutdown component. The topics in this article are as follows:

the State management of long-time data (such as cursors. You cannot tolerate lag or pause when an operation is being processed by your application. If an operation is time-consuming and resource-consuming, You need to detach the operation and perform asynchronous processing on it, so that your application remains responsive and users can process their transactions. This principle applies to disk read/write

Although Android smartphones and tablets are faster than a day, developers must remember that their applications are still running in a resource-intensive environment, this environment relies primarily on batteries and processors that are unmatched by the latest desktop or laptop. Some of the methods described below can help your applications to "slim down" or "Ten Key Points for Android to improve

In Android apps, the most memory-intensive is the picture resource. And on Android, when reading bitmap bitmap, the stack size of the pictures in the virtual machine is only 8M, and if exceeded, a outofmemory exception occurs. Therefore, the memory optimization of the image is an important part of Android application

both IOS and Android are popular mobile operating systems, used by mobile terminals and smart devices, both of which are designed with advanced software technology, and use advanced design patterns to facilitate application development. What technologies are used in the design of the framework? What design patterns are used? What are the similarities and differen

BackgroundThe MVP architecture has been very popular in Android for the past few years and has become almost the mainstream framework, making business logic and UI operations relatively independent, making the code structure clearer.MVVM in front of the fire is a mess, and on the Android side but basically did not see a few people in use, see the introduction of MVVM is also the most talk about DataBinding

In Android applications, image resources are the most memory-consuming resources. In addition, in the Android system, when reading bitmap, the size of the image stack assigned to the virtual machine is only 8 Mb. If the size exceeds the threshold, an outofmemory exception occurs. Therefore, image memory optimization is an important part in Android
