1、国外教程网站 http://www.vogella.com/tutorials/android.html 很不错的网站，免费的，包含android的教程也比较全面，并且教程中经常引用大牛blog，会有很多意外发现。代码资源有提供，但是不是很好找。
http://www.tutorialspoint.com/android/ 非常适合入门，提供基本所有的基础教程，并且N多的例子。除了支持在线学习外，还提供基本教程和进阶教程的pdf下载。（ps:虽然Pdf可以点击下载，但是人家还是希望您能付款的。）
http://code.tutsplus.com/categories/android-sdk 每篇文章质量都非常高～～
http://guides.codepath.com/android/Home 基本包含了日常开发中所有用到的东西，正如: We don’t waste time with the “theoretical
approach” you might get from a book. We cover exactly the things we use every day as we are developing apps for contracts.他们的宗旨是：mission to change the way engineers learn new technologies。同时提供了问答的支持，也欢迎大家的加入。 http://www.coderzheaven.com/android-tutorials/
覆盖各种教程，关于Android基本时案例驱动的方式。 https://newcircle.com/category/android/ 貌似是个培训机构，多数是收费的，不过仍然有一些free resources值得你去挖掘。 http://www.coreservlets.com/android-tutorial/ 虽然主打不是android，但是android的教程也是相当不错的，更好的是，教程都提供pdf、ppt、源码的下载。期待它的更新～
