As any mobile platform continues to develop and its applications are constantly improved, quality becomes crucial if development is successful. Today, users require that they decide to install Android applications on their own devices to respond quickly and with reasonable performance. If those applications fail to provide exciting features and stable user experience, they will soon be uninstalled. This art

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

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

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
