Technical Articles

Detailed Explanation of DiffUtils, Myers’ Algorithm, and Jetpack Compose: This article explores how DiffUtils uses Myers’ algorithm to calculate minimal list changes in Android. It compares this with Jetpack Compose, which uses state-driven UI recomposition and smart-skipping, rendering traditional DiffUtils unnecessary while achieving similar optimizations via Keys in LazyColumn.
Analyzing Android Rendering Mechanism with Source Code and Perfetto: A deep dive into the Android rendering pipeline, covering key components, Vsync processing, and the application of Perfetto for performance analysis.
Improving Rendering Fluency with GPU Hardware Acceleration: Analyzing how hardware acceleration enhances animation and complex rendering fluency, specifically exploring RenderThread and its implementation details via Perfetto.
Meet the Android Studio Team: A Conversation with Jamal Eason: Jamal Eason, Director of Product Management, shares his journey at Android Studio, focusing on product quality, AI integration (Gemini), and cross-team collaboration for App Quality Insights.
Android Weekly Issue #661.
Android Bytecode Processing - Instrumentation with AsmClassVisitorFactory: Using ASM to modify Java class behavior during the build process, covering insertion, deletion, and modification of fields and methods.
