About Me

Hello, I’m Gracker.

I currently work on Android system optimization and application performance stability. My main research interests include Android Framework, Android APM, and Android System Optimization. I also have some experience with Android App development and Linux. I am based in Chengdu and open to professional exchanges.

Technical Sharing

I have been working with Android for a long time, mostly with smartphone manufacturers. I enjoy sharing the knowledge I’ve accumulated. My blog primarily covers Android development, but I plan to add more content related to Android APM, Linux, Android Framework, and tools that improve development efficiency.

I focus on updating three main series:

1. Systrace Series: Explaining key Android operating mechanisms using Systrace to help you quickly grasp Android Framework basics. Systrace is also a powerful tool for performance analysis.
2. Perfetto Series: Perfetto is Google’s next-generation performance analysis tool, designed to replace Systrace. It includes all of Systrace’s features plus additional capabilities, performance improvements, and SQL support.
3. Performance Analysis & Practice Series: How to analyze real-world performance problems, which tools to use, and step-by-step analysis guides.
4. Stability & Optimization Series: Covers smoothness, responsiveness, memory, ANR, Crash, and power consumption, including basics, case studies, and tools.

Final Words

You should really ask yourself every moment:
Is what I am doing right now the most important thing I can participate in?
If you are not doing the most important thing,
Why?
