The recent two-dimensional code is really getting more and more hot, casual TV, online, shopping malls, everywhere are two-dimensional code. and embedded two-dimensional code scanning software is more and more, QQ, micro-letter, UC Browser and so on applications can sweep a two-dimensional code scan, feel our own application without two-dimensional code scanning function, are not up to the trend of the times. So today I'm going to take you along and add two-dimensional code scans to our own prog

Many open source libraries (Butterknife, Retrofit, activeandroid, and so on) use annotations to simplify code to improve development efficiency.This paper briefly introduces the following Annotation example, concept and function, classification, customization, parsing, and analyzes several Annotation principles of Android Open Source Library .PDF version: Java annotation.pdf, PPT version: Java annotation.pptx, Keynote version: Java annotation.keyThe f

There is already an android Project. In Project B, Project A needs to be integrated as a module.How to implement it?

Integrate javascript API documentation into Android projects, which is simple and practical. At this time, you can no longer use the original UI. With HTML + JS + CSS, you can make various UIS. It should be noted that, using this method to develop programs, the software running efficiency will be slower than the original UI, but the UI interface is more beautiful and flexible. Step 1: Go to the http://jquer

develop a sense of right:1.api没你想象的那么重要（记住业务使用的核心类就好），重点把握业务逻辑和代码架构搞好，如果可能的话最好搞清楚内部的机制原理，撸一把源码，写一个自己的框架。2.发生错误要学会自己解决（Debug+LogCat+文档），自己解决不了Google，Google不了整理下思路问身边比你牛B的人（最好给自己解决问题设置个时限，如果一个比较棘手的问题解决超过半个小时搞不定，那么暂且搁置下）。3.***第三方框架不要慌，docs打开帮你忙。如果你还是学不会，只能怪你非人类***哈哈，这里开了个玩笑，我们要正确地掌握第三方库的两种导入源码的方法，有了源码和文档，相信我们学起第三方框架来应该会得心应手。导入第三方框架观察源码1.在lib同级目录下面添加properties文件，文件的名字就是需要导入的第三方库.jar.properties,记得重启自己的工程偶2.直接讲第三方库的library文件作为工程导入自己的工作空间。4.工欲善其事，必先利其器。积累一些常用的非常好的网站和工具（反编译工具等等），可以解决你的很多难题！好站集锦：1.在线jso

In the above section, we have finished building the Jenkin environment. Next we will start to practice this automatic build system.Jenkins defines a set of building processes, and the building details need to be written. Some scripting languages are needed as the adhesive to help with this process. Currently, it supports linux shell, windows batch, ant, python, and other scripts. Here I use linux shell to complete automatic packaging of an android App
