19:40结束阅读Android开发词汇文档(竟然看得完-_-!)

Per Material design guidelines, any touch target on the screen should be at least 48dp wide by 48dp tall. That way, a button in an app on one device will be approximately the same physical size as that button in the same app running on a device with a different screen density.

The Android convention is to give a global variable a name starting with lowercase m for member, which is an alternative term for “field”.

To respect the user’s preferences, you should specify all font sizes in scale-independent pixels. All other measurements should be given in device-independent pixels (dp’s).

21:30分看完Lesson1A

12月11日开始看Lesson1B，搭界面（太他妈简单）

RecyclerView...

12月12日，开始看Lesson2，搭界面的第二个app，View套View，就是Html里面的div套div

12月13日，Lesson 3

Lesson 3讲的是面向对象编程，因为我有对象了，直接跳过，过了一遍Android API, 看了其中一些Android相关的东西，例如Common Intent。

接触到例如Volley和Glide等巨强大的网络库

至此，Android开发已入门。

继续进入Android开发进阶阶段
