4. The MVP architecture analysis of Open source project Philm

   Recently, I have been studying Chrisbannes's Open source project Philm, its overall architecture is a set of MVP implementation, because I did not encounter the whole project using the MVP architecture, see more is some code snippets, Here is a discussion of how Philm combines the actual Android problem to achieve an MVP architecture, if there is inaccurate analysis of the place, welcome to point out, we discuss together.

6. Gradle Modifying the Maven warehouse address

8. Why we can update the UI in a non-UI thread

   See such a title ... estimated that more than n people would say I was teasing ...

10. Guava is a wheel of the wind Basic tools (1)

    Guava is a good friend of Java developers. Although I use guava in development for a long time, guava API figure throughout the production code I write every corner, but I use the function is only guava function set a few poor true subset, let alone I have no time to seriously dig guava function, no time to learn The implementation of guava.

12. Android Best performance Practice (ii)-Analyze memory usage

    Since Android is an operating system developed for mobile devices, we should always take the memory issue into account when developing applications. Although the Android system has a garbage collection mechanism, this does not mean that we can completely ignore when to allocate or free memory. Even if we all follow the programming recommendations given in the previous article to write programs, there is a good chance of memory leaks or other types of memory problems. So the only way to solve the problem is to try to analyze the memory usage of the application, and this article will teach you how to analyze it.

14. Android Main thread Tour-PSVM

    When I hit a bug that was related to the Android main thread interaction, I decided to take a good look at what the Android main thread was all about. This article describes the first part of my Android main thread tour.

16. Java Annotation Processor

    Annotations in Java (Annotation) are a magical thing, especially now that many Android libraries are implemented using annotations. In this article, I'll explain how to write a note processor (Annotation porcessor). In this tutorial, I'll start by explaining to you what a callout is, what you can do with this powerful tool, and what you can't do, and then I'll implement a simple note-making device step-by-step.

18. Ways and tricks to optimize Android apps on x86

    Intel is committed to helping developers deliver Android apps that work properly (and even run well) on Intel architectures. While Intel focuses on the community level: Optimizing Dalvik Java, V8 engine and Bionic C, enriching the code base, and providing IA with 32-bit and 64-bit cores, they also offer several types of new tools to help Android developers. These tools are primarily used to improve performance beyond the default ARM conversion layer for x86: the performance provided by Libhoudini.

Design

1. A full analysis of the Twitter video function design process

   In this 7000-word article, the Twitter designer shows the rigorous design process and design development collaboration experience. The Twitter design process is worth learning: 1. Prototype design to drive the design direction, can be interactive, easy to test, to determine the feasibility of development. 2. Pay attention to the design and development of communication, will be a lot of designers to do better development work transferred to the designer, the project follow-up solid, and in the AE die "design" details, rather than simple prototype, early assistance to develop the adjustment effect, production "product" 3. Finely crafted, 750+ static design variants, 54 Prototypes visible Detail. 4. Problem summary, bug discovery, user testing is not related to the designer. 5. Any thorny implementation problem, many development questions, many small discoveries have a large impact.
