Dive into Kotlin Delegation implementation to solve the obfuscation issue
This document discusses implementing Kotlin delegation and solving Proguard issues. It provides two solutions to an issue where the "No BuiltInsLoader implementation was found" exception is thrown after Proguard strips metadata files. Solution 1 is to add the kotlin-reflection library, which increases APK size by 100KB. Solution 2 is to add a new Proguard rule to exclude kotlin library classes and metadata files from being stripped. The document also provides references to related issues and hiring opportunities.
U/T/B-Driven Development
a presentation in Android Taipei at 2018/12/27 about how we adoptive different kind of development process in the team.
Job-to-be-done theory to practice : Ch4 Process
This document discusses applying Jobs-to-be-Done (JTBD) theory to practice. It outlines the key steps in a JTBD process including conducting competitive analysis, formulating an innovation strategy, targeting hidden growth opportunities, and formulating market and product strategies. It provides examples of how Motorola segmented users based on the specific jobs they needed to get done. The document emphasizes that JTBD helps align product offerings with customer needs and communicate value propositions based on outcomes important to customers.
20180524 Android Taipei : RxJava Threading
This document discusses reactive programming and multi-threading in Android. It introduces the need for threads to avoid UI blocking. It then discusses common threading problems like progress updates and dependencies. It presents solutions from Google like AsyncTask and Handler/Looper as well as Java utilities. It also discusses deferred-promise patterns from libraries like Bolts and RxJava concepts like explicit execution and cancellation. It advocates for RxJava as a way to more easily manage threads and transformations with fewer side effects.
Why reactive programing matter, and how PicCollage adaptive it.
The document discusses PicCollage's journey to adopting reactive programming in their Android applications. It outlines why reactive programming is important, how PicCollage struggled with threading issues originally, and the steps they took to transition to reactive programming. This included first making UI interactions reactive, then implementing reactive threading mechanisms, making their data layer APIs reactive, and finally making controllers reactive as well. The document provides references and recommendations for learning reactive programming.

Introduce Flutter Development
This document discusses Dart and Flutter. Dart is a programming language similar to Java but with advanced features like async functions, optional methods, mixins, and first-order functions. Flutter is a UI framework for building mobile, desktop and web apps using Dart. It does not provide a full UI framework like GWT as developers may not want to reuse components across platforms. Examples of Flutter features mentioned include hot reload, the element inspector, and support for touch events.
JTBD case study : Uber Rider App
This document discusses how Jobs-to-be-Done (JTBD) analysis shaped Uber's latest app update. It analyzes Uber's core job of bringing riders to their destination as fast as possible and compares it to competitors like public transit, taxis, and Lyft. It then describes how Uber enriched the riding experience through features like Uber Feed which integrate food ordering and social sharing to better fulfill the job. The document raises questions about how JTBD could improve onboarding and calls integration between Uber and Yelp into question.
20180124 android taipei_arinterface
This document discusses using Unity and ARInterface to enable cross-platform AR development. It recommends starting with Unity3D to write code once and deploy to both ARKit and ARCore platforms. It also provides sample code links and specifications for ARKit and ARCore, warning of version requirements needed to use ARCore plugins from Unity.
JSON's big problem android_taipei_201709
The document discusses parsing large JSON files and compares different JSON parsing libraries and approaches. It recommends a streaming approach for performance over the traditional approach if performance is important. It also notes that the sketch path data in collage editing JSON may not be needed.
ARText in Cocoaheads Taipei 201709
This document summarizes the journey of developing an ARKit app in Unity3D. The original team encountered several challenges including changing ARKit APIs, needing to purchase plugins for features like sharing and storage, and performance issues with Unity's ARKit plugin. They overcame these obstacles by writing bridge code between Unity and native iOS code to access ARKit, Metal, and AVFoundation APIs for better performance and video recording support. While Unity provided cross-platform benefits, a custom native app would have better UI performance and control without dependencies on Unity plugins.
PicCollage - modules map
This document outlines the modules, libraries, and components that make up an Android application for creating collages. It describes the purpose and responsibilities of each module, including lib-image-loader for loading images, lib-util for shared utilities, lib-component for common components, lib-widget for widgets, lib-reactive for reactive programming, lib-history for undo/redo, and lib-collage-editor for editing collages. It also addresses some questions about where certain components should be located and future plans to add additional modules.

Firebase analytics event_201607
This document discusses using Firebase for A/B testing and analytics. It provides steps to set up Firebase remote config and analytics for A/B testing an app design. Previously, the company built its own A/B testing framework, but it slowed release cycles. Firebase offers a powerful configuration system and real-time analytics. The document outlines setting up Firebase for a project manager and developer. It also shares results after a week that bottom navigation performed best. In summary, Firebase provides an easy integration for A/B testing and analytics with a small library size, but has some limitations around device support and analytics capabilities.

網碼邊界(Edge of Network Libs)
This document summarizes the speaker's experience over several years working with various image loading libraries for Android. It describes using AsyncTasks initially for image loading in PicCollage apps. It then evaluates several popular image loading libraries (Android Query, Universal Image Loader, Picasso, Volley) and notes their features like default cache size and approach to image loading. The document also discusses using Retrofit and Ion libraries and compares various aspects of the default libraries.
那些年，我們一起玩的萬花筒(Kaliedoscopic)
The document discusses an Android developer's experiences using OpenCV for image processing tasks in Android applications. It mentions using OpenCV for tasks like converting between RGB and YUV color spaces, applying filters like Laplacian, and chaining or running tasks in parallel. OpenCV provides high performance image processing and avoids issues with fragmentation in the Android camera APIs. Examples are given of using OpenCV to record video and do face detection.

the presentation for Android Taipei in EZTable. the topic is talk about the CI and Testing.
期末專題報告：嵌入式系統之影像處理器
2007到2008年的專題製作，那些年的無知、熱情及困惑，最後做出一個還算滿意的作品，開啟了對程式的樂趣，對影像處理的偏好，以及對數學的熱忱；也許現在忘了怎麼寫C，可能連傅立葉轉換的演算法的實作有些生疏，但仍忘不掉當初花了一個上午解一個很鳥的BUG。
Continues integration development
The document discusses the benefits of using Jenkins for continuous integration (CI). It describes some common problems in development workflows without CI, like wasted time and difficulty in ensuring quality and consistency. With Jenkins, development and testing can be automated, issues are caught early, and quality is improved. Jenkins provides a easy to use, extensible platform to help teams work better together and spend more time on meaningful work.
