Record bit by bit to optimize application performance: Do not use static constants or Activity constants in the activity
During the development process, sometimes static constants are used in the Activity. As a beginner developer, we often directly define static constants in the Activity, in this way, the Activity cannot be completely destroyed, that is, the Activity still occupies a thread, unless the thread is forcibly killed, in order to improve the performance of the application, during development, we will create a class to save these static constants. In this way, we only need to call them directly, so that when the Activity exits, this thread will also be abolished to improve application performance.
