Android Dev

Using Java annotations, developers can show their intent and let AndroidAnnotations generate the plumbing code at compile time. Few Features are * Dependency injection: inject views, extras, system services, resources, ... * Simplified threading model: annotate your methods so that they execute on the UI thread or on a background thread. * Event binding: annotate methods to handle events on views, no more ugly anonymous listener classes! * REST client: create a client interface, AndroidAnnotations generates the implementation. * AndroidAnnotations provide those good things and even more for less than 50kb, without any runtime perf impact!

"First off, the difference between android:gravity and android:layout_gravity is that android:gravity positions the contents of that view (i.e. what's inside the view), whereas android:layout_gravity positions the view with respect to its parent (i.e. what the view is contained in). "

"Ice Cream Sandwich (ICS) sports two new widgets that have been designed to support the richer user interfaces made possible by larger displays: Space and GridLayout."

"This library provides a version of GridLayout that works across all versions of Android 1.5+. As a side effect, this library also includes the lightweight Space as well."

Arguably the worst part in playing around with Android is its insistence to put that ugly title bar above everything I do as a default to Activities. Thankfully, the framework allows one to change this behavior.This post is going to explore the ways in which we can create custom title bars and more importantly just how far we can push the limits.

Using the Eclipse GUI does not allow one to easily: (a) Add custom build steps (b) Use an automated build system (c) Use build configurations (d) Build the release project with one command.Fortunately, the Android SDK comes equipped with support for Ant.This tutorial will show you how to incorporate an Ant build script into your Android projects,even if you still develop with Eclipse.

"A collection of useful, open source applications that demonstrate basic features of the Android platform."

" In the latest Android Design in Action Roman Nurik (watch in YouTube) did a great roundup of UI design patterns that have not yet made their way to the official guidelines but are starting to appear in apps more frequently"

Android, a rich platform for application development, has an attractive set of user interface elements and data-management capabilities. Android also offers a healthy array of interfacing options. In this article, learn how to interact with Android's varied sensor options to monitor your environment. Sample code shows you how to record audio on an Android phone.

ICS-centric design 的开源Library

想到就悶 官方擴充套件既然要主推Action Bar pre3.0還要去找第3方套件。 雖然後來他們也有出Action Bar compatibility， 但真的是不好用。

Google Android在Design方面一直是一个赶超者，直到ICS才多少得到些尊重。这才名正言顺的出了一系列"范式"。 在此之前，都是依赖开源社区的"试探性"的尝试，这些尝试"是否能用"尚且还是个未知数，就更别说"是否好用"了。 终于Android开始要'统一江湖'了，积极的第三方开发者也开始认可'统一'的方向，这是件好事. ICS的设计很优雅，更重要的是官方多次突出强调与iOS的区别，这让我很有归属感 :)
