Android Performance is a Chinese technical blog maintained for many years by Gracker/Gao Jianwu. Its core topics include Android performance optimization, Android Framework, Systrace, Perfetto, ANR, lag, startup, memory, power consumption, and more. The site is not a traditional online education platform, but rather a collection of a personal technical blog, project index, article directory, community entry points, and open-source project records.
The site’s greatest value lies in its systematic performance analysis content. In its earlier years, it featured series on Systrace fundamentals and practical usage; in recent years, the focus has shifted to the Perfetto series, covering topics such as CPU, Binder, Vsync, MainThread, RenderThread, trace capture, and local analysis. In addition, the author continues to document practical work with AI Agent and automation tools such as SmartPerfetto and OpenClaw, while also maintaining Android Weekly, a Knowledge Planet community, and entry points to several technical discussion groups.
The public blog articles are free to read, and Android Weekly is also described as a free newsletter. The articles mention The Performance Knowledge Planet as a paid community focused on Android performance optimization knowledge and case analysis, but the crawled content does not show a specific price, so it would not be appropriate to infer one.
The strengths are its highly focused content, long-term updates, and Chinese-language explanations that are friendly to developers in China. The author has experience with smartphone manufacturers and performance optimization, and many articles are based on real tools and practical cases rather than merely restating concepts. The Perfetto/Systrace-related content is especially rare and well suited as desk reference material. The downside is that the blog format is relatively loose and lacks the structured learning progress, assignments, and Q&A support found on course platforms. Some articles are quite in-depth, so beginners without a foundation in Framework, Linux, or rendering pipelines may find the reading barrier relatively high.
It is best suited for Android app performance optimization engineers, system/Framework developers, APM R&D engineers, smartphone manufacturer performance teams, and mid-to-senior developers who want to understand how the Android system works from a trace perspective. Complete Android beginners can read some of the foundational articles, but should not treat it as a zero-to-one beginner tutorial.
Judging from the domain and the Chinese-language content format, the site is aimed at Chinese developers and can usually be accessed directly. Some external links, such as GitHub, OpenAI, and Google NotebookLM, may be unstable to access from mainland China, but this does not affect reading the main blog content.
