The path to Android learning

Received some friends of the micro-blog private message, said can give some guidance to Android novice, I can only say that guidance is not, after all, I am also a lot of things are learning, at the same time a college students are ready to switch to Android, can be said to start from the beginning, then I would like to give some advice on an experienced identity Just hope that in the course of learning can be less to write detours.

Hardware

• PC – Recommended Mac

First of all, I am not the fruit powder, personal windows,linux,mac ox system have been used, can only say that Windows development tools are simply difficult to compliment, especially the command line super difficult to use, and Linux itself must spend a lot of time in the toss, is not suitable for novice, Max OS is I think the most useful system so far, not one, so if you are not bad money, it is strongly recommended to start a Mac, recommended Pro Series, of course, its price is indeed more expensive, if the temporary difficulties, recommended later on hand when the time to start, will bring you a quality experience. (Google's engineers are using the Mac, should be more convincing it)

• Mobile – Recommended Nexus 5

Android development is the most unbearable is that turtle speed simulator, highly recommended to start my Google Nexus series, native ROM, cost-effective ultra-high, conditional recommendation to start a Xiaomi or Samsung, not because they have more useful, It's because the two brands on the market now have the largest share of mobile phones, which may need to be adapted and tested in practice, in short you need an Android phone. You may also need to know that the Meizu has a smartbar, although I think it is really sb. In the end you still have to use the simulator, then let you recommend a more rapid simulator bar--genymotion, specifically see me this blog a powerful Android simulator genymotion

Development environment

• Eclipse ADT

Google helps you integrate a complete Android development environment, including a custom eclipse + ADT plugin, as well as the latest SDK and source code

• IntelliJ idea

It is more recommended to use idea than with eclipse and can be seamlessly transitioned to Android Studio later

• Android Studio

First of all, this is not suitable for beginners to use, but you must know that this is Google's latest Android development tools, based on idea, compiling dependent gradle, There is no 1.0 official version yet, but you can still be familiar with the amateur program, as this may be the future of Android development tools

Turn over the wall

As the saying goes, not to turn the wall programmer is not a good programmer, especially recently Google services are blocked, the above IDE download will need to turn over the wall, here is recommended a reliable VPN bar, support multi-device Mac, Windows, Android, iphone, etc., If you and the small partners together to buy the monthly only a few dollars, the circle of friends are in use, if you buy through the link below, you and my account will be increased by 10 yuan.

Ladder VPN

If you don't want to flip the wall anyway, here on GitHub you can download the above Android development tools directly

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:

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.
