Startup optimization is a commonplace issue in Android optimization. As we all know, Android startup refers to the process from when the user clicks on the icon to seeing the first interactive frame.
The startup process can be roughly divided into the following stages:
- fork creates a new process
- To create and initialize the Application class, create the four major components, etc., go to Application.onCreate()
- Create launchActivity and complete the onCreate, onStart, and onResume life cycles
If you delve deeper and deeper into it, you can find a lot of "black technology" that can be operated. There are many solutions such as mutilDex optimization, message scheduling optimization, and json preheating.
In order to facilitate everyone to study more issues of Android performance optimization, I recommend to you a collection of practical Android performance optimization projects from teams such as Tencent, ByteDance, Alibaba, Baidu, NetEase, Meituan, Google, iQiyi, etc. to learn from Performance optimization technology from major manufacturers, check for leaks and fill in gaps. If you need it, click on the card at the end of the article to get it for free.
