Welcome to follow.
This article explains the iOS code‑signing process for developers, covering Apple developer account enrollment, certificate creation, private key generation, provisioning profile types, automatic signing in Xcode, and step‑by‑step re‑signing of IPA files using the codesign tool.
The article explains how to move beyond macro app metrics by collecting offline and real‑time user data, storing it in HDFS, processing it with Spark, visualizing behavior paths as state‑machine trees, and performing branch‑funnel analysis to uncover conversion bottlenecks and improve product quality.
This article explains the Android ANR mechanism, common scenarios that trigger it, how the system detects and logs ANR events, and provides step‑by‑step methods for locating and fixing ANR issues, illustrated with a recent WeChat bug example.
These twelve interview techniques guide designers on reducing participant tension, framing sessions as casual chats, asking progressive questions, avoiding leading language, preventing overly open queries, keeping users speaking for themselves, observing micro‑expressions, steering clear of design suggestions, avoiding answer cues, encouraging storytelling, and effectively analyzing collected insights.
This article presents a multiplexed system testing environment that uses token‑based encoding and decoding to share a single baseline environment among multiple testing scenarios, detailing its architecture, technical components, protocol adaptation, token handling, and Zookeeper‑based configuration management to improve resource efficiency and testing speed.
This article presents two experimental methods for automatically obtaining load‑time metrics of mobile H5 pages—one leveraging Chrome DevTools Protocol to collect network, page, DOM and runtime data from Android Chrome/WebView, and another using computer‑vision techniques to detect progress‑bar visual cues in recorded screen videos.
This article explains how to overcome Xcode's limitations by using command‑line tools such as libimobiledevice to automatically collect crash logs from third‑party iOS apps, symbolicate them without dsym files, and analyze the resulting CrashReport structure for effective debugging.
The article explains how traditional user research methods struggle to keep pace with fast‑moving internet product cycles and proposes an agile, business‑oriented research framework that shortens study time, improves cross‑functional communication, and ensures research outcomes are actionable and aligned with product goals.
This article explores how deep learning, specifically convolutional neural networks built with Caffe, can be used to automatically detect and predict static UI compatibility bugs such as text overlap in mobile app front‑ends, reducing reliance on manual testing.
This article provides comprehensive iPhone X UI design guidelines, covering screen dimensions, safe‑area layout, status‑bar adjustments, home‑indicator considerations, color gamut updates, Face ID integration, custom keyboard rules, larger navigation bars, and resources for designers and developers.
