create a UI for the layout alone, we create an app that abuses memory, and it has a nasty delay in the UI. To achieve a smooth, low-footprint UI, the first step is to search your app to find out the potential bottleneck layout. Use the Hierarchy Viewer tools tool that comes with the Android sdk/tools/.Another good tool is lint, which scans the application's source code for possible bugs and optimizes control results.Recommendation 10: How to fix the

Because it is memory friendly, but also "secretly" to help us do a lot of things. For example, memory cache, bitmap multiplexing, fixed photo direction, and so on. Of course, in order to meet a variety of needs, just loading pictures is not enough, you also need to make a variety of images, that is, transform
