The article explains how feedback transforms mere repetition into meaningful iteration by comparing recursive sequences and linear functions, illustrating the concept with learning cycles and Kandinsky’s artistic process, and showing when feedback matters most for effective growth.
The 2024 Inclusion·Bund Conference hosted a multidisciplinary forum on AI-era creativity, featuring scholars from Fudan University, East China Normal University, Tongji University, and iFlytek who presented reports on AI's impact on culture, ethics, and creative practice, followed by a round‑table on human‑AI symbiosis.
The article analyzes why Android 14's debuggable runtime became significantly slower due to a change from the nterp interpreter to the switch interpreter, explains the underlying ART modifications, and presents the Google‑provided fixes that restore performance to Android 13 levels.
The severe jank observed in Android 14 debug builds stems from the DEBUG_JAVA_DEBUGGABLE flag triggering DeoptimizeBootImage, which forces boot‑image methods onto the slow switch interpreter; a temporary hook clearing the flag and a permanent fix using UpdateEntrypointsForDebuggable restore performance, with Google planning an official fix in Android 15.
This article explains how the Android Runtime (ART) implements the Java synchronized keyword at the native level, detailing the roles and interactions of Monitor, LockWord, and native Object classes, as well as the thin‑lock to fat‑lock upgrade process and monitor entry/exit mechanisms.
The article explains that Android TV plugins can crash on Android 9 when the ART runtime inlines methods across dex files after an upgrade, and proposes a build‑time fix that scans for vulnerable call sites and injects lightweight try‑catch code to disable inlining, eliminating the crash.
The article explains the Android Dex format, its compact bytecode advantages, how d8 generates Dex files, details each structural component—from header and ID tables to class data and bytecode—covers encoding schemes, endianness, and demonstrates inspection with the dexdump tool for deeper ART understanding.
This article introduces the fundamentals of Android Runtime (ART) garbage collection, covering its historical background, key milestones, core features such as RegionTLAB, read barriers, pause behavior, generational support, target heap size calculations, multiplier impact, GC trigger thresholds, Systrace analysis, and parameter tuning strategies.
The article explains Android R’s ART runtime garbage‑collection configuration and heap layout—including RegionSpace, ImageSpace, ZygoteSpace, non‑moving and LargeObject spaces—details concurrent, native, transition and blocking GC types, illustrates real‑world performance issues, and offers optimization strategies for developers.
The article explains Android’s DEX compilation flow, the transformation of DEX into VDEX and ODEX during ART pre‑optimization, why ODEX lacks the original classes.dex causing ARouter routing failures, and how disabling dex stripping in the build restores the missing classes for stable navigation.
This article investigates an Android JNI native crash caused by misusing NewString(), examines why a custom UTF‑8‑to‑UTF‑16 conversion was used instead of NewStringUTF(), compares Dalvik and ART string encodings, reveals a Dalvik UTF‑8 conversion bug fixed in ART, and advises developers on encoding nuances across Android versions.
