• Organize your Android development resources

Self-organizing some of the Android development resources, including development, tools, design, etc., I believe it will be useful to you

Android Design

Before you develop an Android app, you need to understand the design specifications for the Android platform, a series of tutorials on Android design and Google's latest material design Chinese translation.

Android Compatibility library

When you understand that the design specifications are ready to start developing your app, you also need to consider the version that your app supports, and if it's a brand new app, it's recommended to support 4.0+ directly in terms of current market share, although 2.3 of the share is still part of the app, but how much of this is actually used by people. Of course, if your company must require support for the 2.x version, then don't worry about it, here are a few of the compatibility libraries that you can fit:

• Actionbarsherlock

A Actionbar compatible library of the Great God Jakewharton, supported in the 2.x version Actionbar

• ActionBar Compact

Before this use Actionbar basic will use the above Jakewharton compatibility library, but currently Google has its own set of Actionbar compatibility library, recommended the use of Actionbar Compact, specific introduction and use of the method described in my blog

If you need a compatible version of 2.x, you need to use the following classes in the V4 package, such as fragment, Fragmentmanager, Fragmentactivity, Fragmentpageradapter, Cursorloader, Loadermanager, Asynctaskloader

Of course, there are some new controls underneath the V4 package, you have to know.

Navigation Drawer (navigation drawer)

Prior to implementing a drawer navigation on Android you might use the Slidingmenu Open Source Library, and now you can use the official Drawerlayout control to easily implement

Slidingpanelayout

Slidingpanelayout is a newly added component in the V4 package, which allows the two-column panel to be switched, using the link to the effect, see Blog

Swiperefreshlayout

Swiperefreshlayout is a drop-down refresh component of Google's support V4 19.1 version of the library update, which is handy for Google Now's results.

Some open source libraries that Android developers must know

When it comes to the open source Library, you have to mention GitHub, only to say that the most active open source community, do not know to quickly register an account to use, is definitely your fast technology to improve the weapon.

Volley

While app development is inevitable to interact with the server, volley is an open source web communication library that Google officially launches, making it easier and faster to communicate on the Web.

• Volley Full Parse

• Android Volley Sample

Activeandroid

Activeandroid is a lightweight ORM (Object Relation Mapping) framework that simply uses methods such as Save () and delete () to do additions and deletions.

• Activeandroid–android Lightweight ORM Framework

Retrofit

Retrofit is similar to the ORM concept in the Java World, where ORM transforms structured data into Java objects, and retrofit transforms the data returned by the rest API into Java objects for ease of operation. It also encapsulates the invocation of network code.

• Retrofit–java (Android) Rest Interface Encapsulation Class Library
