Currently, the “Knowledge Planet” (ZSXQ) is a paid community. The income mainly goes towards blog server costs and buying cat food for my cat, Douzi. It also serves as my motivation to keep updating the blog. If you find the content helpful, consider joining to support the work! Thank you very much!

The community is named The Performance, a circle for sharing Android performance optimization. I am the host—an Android performance developer at a top-tier smartphone manufacturer in China with years of experience in performance, power consumption analysis, and case studies. This community provides a one-stop-shop for performance knowledge, covering fundamentals, methodologies, tools, and valuable real-world case analyses.

As Android evolves, performance optimization has become a top priority for both smartphone manufacturers and app developers. However, performance is a broad topic, involving everything from the Kernel to the Framework and Apps. Each layer requires deep knowledge. Our team established this technical circle to provide high-quality sharing and systematic learning for Android performance optimization.

All members are welcome to share knowledge and cases, ask or answer questions, and grow together. We focus on the following topics:

The current content plan (labels marked with ##) is as follows:
