This article examines common memory leak and performance problems in C/C++ applications, categorizing causes such as pointer loss, improper memory release, excessive fragmentation, infinite allocation, and container misuse, and discusses diagnostic techniques, underlying allocation mechanisms, and mitigation strategies.
This article presents a comprehensive analysis of real-world C/C++ core dump cases, categorizing common causes such as stack integrity, memory leaks, multithreading issues, and misuse of system libraries, and offers practical debugging strategies and code examples to help developers prevent and resolve such crashes.
The article outlines comprehensive automated performance testing approaches for Android and iOS applications, covering challenges of data accuracy, reliability and volume, and describing configurable UI automation, remote device management, data collection, and reporting mechanisms to enable scalable, low‑effort mobile testing.
This article explains how to obtain iOS diagnostics battery data on iOS 10+ and iOS 9 devices, interpret the SQLite tables to measure app power consumption, and provides practical code and performance‑optimization tips for reducing energy usage in iOS applications.
This article explains what scenario modeling is, outlines its five‑W‑one‑H elements and step‑by‑step workflow, and demonstrates its practical value through a mobile input‑method game example that improves product usefulness, usability, and user satisfaction.
The article compares the classic waterfall software development model with iterative development, outlines the drawbacks of the former, highlights the six advantages of iteration, and details a multi‑iteration parallel approach with QA and release‑cycle practices for improved project control and product quality.
This article explains how to employ Apple's AVFoundation framework to capture camera images on iOS, initialize the necessary device input, session, and output components, and then use CoreImage's CIDetector to perform face detection, including code snippets and a practical demo.
This article demonstrates how to automatically enable USB debugging on a non‑root Android phone after reboot by installing a high‑permission app that uses an AccessibilityService to detect the debug state, launch the developer options, and simulate user interactions to toggle the setting.
The article details how Baidu MTC designed and implemented a universal Android script testing platform that combines UIAutomator, a custom Clean‑SDK for popup handling, image‑recognition algorithms, and a recording‑playback tool to enable robust, non‑native mobile automated testing across thousands of devices.
This article introduces automated testing, explains its purpose and benefits, outlines its pros and cons, identifies project types that are suitable or unsuitable for automation, and describes Baidu MTC’s mobile app testing services across three typical customer scenarios.
