December 2022 Summaries

Apdex is an open standard for measuring the performance of software applications, providing a universal score between 0 and 1 that represents the overall user experience with an app. The 95th percentile (P95) measures outliers in app performance, allowing teams to identify exceptional instances and understand how their app is performing on average. Throughput tracks the number of users and changes over time, while app stability measures crashes per session or user. App loading times assess wait times for launch, screen transitions, and content loading, with specific targets for cold, warm, and hot app launch times. Network response time is crucial, aiming to respond to user requests within 1 second, and app trace completion time examines client-side logic execution time. UI response times monitor the responsiveness of the app's user interface, while screen loading times track page transitions and content loading stages. A proactive app performance management strategy involves monitoring metrics, quality control measures, and proactive tools like Instabug to ensure a competitive app experience.

Instabug's Android Studio plugin provides an easy-to-use interface for integrating the SDK into Android apps, eliminating the need to write code. The plugin is available on the Android Studio marketplace and can be easily installed by searching for Instabug. After installation, users can add their app token, target package, and select products to enable from a simple UI. The plugin's features are actively being expanded to further simplify integration and customization of Instabug's SDK.

Integrating Luciq's SDK into an Android app is designed to be a seamless experience, further simplified by the Luciq Android Studio plugin, which allows developers to incorporate the SDK without writing any code. Available on the Android Studio marketplace, the plugin can be installed from the plugins settings page, enabling users to input their app token, target package, and choose preferred invocation methods and Luciq products through an intuitive UI. The products are integrated with default settings but can be customized by editing the boilerplate code or adding custom code. This first iteration of the plugin aims to enhance the developer experience, with ongoing efforts to expand its features and capabilities for easier integration, configuration, and customization of Luciq's SDK.

The tutorial covers the creation of common UI elements programmatically using PureLayout, a layout system that allows for easy and flexible layout management. It starts by covering the use of UINavigationController/Bar, which is used to create a navigation bar with a back button. The tutorial then moves on to creating a UITableView, which is used to display a list of items. Finally, it covers the creation of UITableViewCell, which is used to render individual cells in the table view. The tutorial also touches on Self-Sizing Cells, which allows for dynamic cell heights based on the content within them. Throughout the tutorial, the author emphasizes the importance of following best practices and using the correct protocols and methods to ensure that the UI elements are created correctly and efficiently.

In the second part of the tutorial on creating UI elements programmatically using PureLayout, the author focuses on explaining how to incorporate essential UI components like UINavigationController, UITableView, and self-sizing UITableViewCell into a mobile application without using Storyboards or NIBs. The tutorial provides a comprehensive walkthrough on setting up a UINavigationController to facilitate navigation within the app, including handling the navigation bar's translucency. It emphasizes refactoring the ViewController by moving UI elements to a separate UIView subclass, adhering to the Model-View-Controller (MVC) architectural pattern to streamline code management. The tutorial also covers the integration of UITableView for displaying contact information, detailing the implementation of UITableViewDataSource and UITableViewDelegate protocols, and the creation of UITableViewCells, including self-sizing cells to accommodate varying content sizes. Through these steps, the tutorial highlights the benefits of building a UI programmatically, such as improved code maintainability and flexibility, while encouraging readers to explore Apple's official documentation for a deeper understanding of UIKit components.

In this video, execution traces are reviewed and their application is discussed. Execution traces can be used to measure time taken for various tasks such as fetching data from a local database or server, and compressing files. Leveraging execution traces provides insight into how different user segments perform across a flow. The review aims to help users understand the benefits of using execution traces in optimizing performance.

Instabug has released an updated alerts and rules engine that provides a better experience for managing stability and performance issues in mobile apps. The new features include a card-based alerts list, activity logs to track changes made to alerts and rules, alert ownership, and the ability to assign specific teams to manage certain alerts. Additionally, Instabug now offers triggers for crashes that affect more than one percent of app sessions within 24 hours, apdex change rate alerts, and customizable alert timeouts to help reduce noise and focus on critical issues. The updated engine aims to empower mobile teams to maintain industry-leading apps with user-centric stability and performance monitoring.

Execution traces are valuable tools for analyzing the performance of various processes, such as the time taken to fetch data from a local database or server and the time required to compress a file. By leveraging execution traces, users can gain insights into how different workflows perform across various user segments, enabling more informed decision-making and optimization of processes.

Luciq's enhanced alerts and rules engine offers new features and an improved user experience to help users efficiently monitor app stability and performance issues. The revamped alerts and rules page includes a card-based list that summarizes each alert's triggers, conditions, actions, performance, history, and assigned team, with options to edit, duplicate, or delete alerts and view activity logs. Users can assign alerts to specific teams, facilitating better management of relevant alerts. New functionality includes the ability to automatically monitor the latest or most adopted app releases, set velocity alerts for crashes affecting over one percent of app sessions in a day, and create alerts for significant changes in Apdex metrics. Alert timeouts, which are currently available only for Slack notifications, help reduce noise by allowing users to set a notification timeout period, with plans to expand to additional channels in the future.

Continuous integration, continuous delivery (CI/CD), and continuous deployment have transformed the mobile software development cycle. With the rise of automation, developers can now ship new app releases on a weekly or daily basis, eliminating the need for manual testing and reducing bugs. Various tools such as Jenkins, CircleCI, Travis CI, Bitrise, Microsoft's App Center, TeamCity, GoCD, Bamboo, GitLab, Codeship, Codefresh, Codemagic, and Instabug are available to automate this process. These tools offer features like automated builds, testing, and deployment, integration with other services, customizable workflows, and pricing plans that cater to different needs and budgets. By investing in a CI/CD tool, developers can reduce errors, increase speed, and improve the overall quality of their mobile apps.

Microsoft announced the retirement of Visual Studio App Center by March 2025, prompting developers to seek alternatives for continuous integration and continuous delivery (CI/CD) in mobile app development. With the acceleration of software development cycles, automation has become crucial for seamless app updates, making CI/CD tools indispensable for reducing bugs, errors, and deployment costs while enhancing speed and efficiency. Among the leading CI/CD tools are Jenkins, CircleCI, Travis CI, Bitrise, TeamCity, GoCD, Bamboo, GitLab CI, Codeship, Codefresh, and Codemagic, each offering unique features, integrations, and pricing models to accommodate varying developer needs. These tools support automation of build, test, and deployment processes, enabling developers to release code rapidly and focus on creating business value. As mobile development requires agile, rapid iterations, choosing the right CI/CD solution involves considering factors like features, integrations, support, and cost.
