The Elements of Art Olive Trees with Yellow Sky and Sun by Vincent VanGogh While exploring one of my favorite Art websites, About.com:Art History, I came across a great explanation of the “Elements of Art”. The author uses the analogy of the Elements of Art being like the “building blocks” that artists use to create their artwork. Similar to how different atoms combine to form other things (ex. hydrogen and oxygen combine to form H2O), the artist combines some or all of the Elements of Art (line, shape, form, space, texture, value, color) to create his painting, drawing, sculpture, etc. Teaching your students about the Elements of Art will give you a common vocabulary with which to talk about Art, whether it be student work or the work of a master from long ago. An Elements of Art “scavenger hunt” using the work of a famous artist is a fun way to test and reinforce your students’ understanding while exposing them to great works of Art.
This is What Michael Jackson Sounds Like in Quechua Even the youngs think Quechua is cool. After the language was translated for a book, a song, and given a shoutout by a fútbolero, we started thinking that Quechua was having a sort of moment. Perhaps the biggest sign of this is that a 14-year-old girl named Renata Flores sang a Quechua version of Michael Jackson’s “The Way You Make Me Feel.” Android Async HTTP Clients: Volley vs Retrofit - Instructure Tech Blog We recently released a new version of our mobile app for Android. Although it was a huge improvement from previous installments in terms of features, design, and usability, there was one nagging issue in the back of our minds: speed. There are times when the app isn’t as snappy as we’d like it to be.
Android: Loaders versus AsyncTask One of the biggest pieces of Android that I have neglected to learn about would be Loaders. Seeing as it’s time for me to learn it, perhaps I can help you out a bit with it as well. My main interest with the Loader concept is how it melds with the tried and true AsyncTask, and if it’s really better or not. AsyncTask RoboSpice Motivations - Aplicaciones Android en Google Play Join the G+ community and register as a tester to get latest alpha/beta versions: Andlytics collects statistics from the Google Play Developer Console. It lets you track active installs, total installs, ratings, and comments for all your Android apps that are published on Google Play. Andlytics can also collect AdMob statistics, including revenue, requests and impressions. It supports background syncing of stats and notifications for when changes occur.
Android Fundamentals: Properly Loading Data The UI thread is a bad place for lengthy operations like loading data. You never know how long data will take to load, especially if that data is sourced from a content provider or the network. Android 3.0 (Honeycomb) introduced the concept of Loaders and, in particular, the CursorLoader class that offloads the work of loading data on a thread, and keeps the data persistent during short term activity refresh events, such as an orientation change. We'll incorporate the Loader as a new feature in our ongoing tutorial series building a yet-to-be-named tutorial reader application. If you were paying close attention to our last tutorial, Android Fundamentals: Working With Content Providers, you may have noticed that we took a shortcut.
Implementing Loaders (part 3) This post introduces the Loader<D> class as well as custom Loader implementations. This is the third of a series of posts I will be writing on Loaders and the LoaderManager: First things first, if you haven’t read my previous two posts, I suggest you do so before continuing further. Here is a very brief summary of what this blog has covered so far. Life Before Loaders (part 1) described the flaws of the pre-Honeycomb 3.0 API and its tendency to perform lengthy queries on the main UI thread.

Android Components The CommonsWare Android Components, or CWAC, are open source libraries to help solve various tactical problems with Android development. Most CWAC components are packaged as a tiny JAR file that you can add to your project (e.g., drop it in libs/), requiring at most other CWAC JARs as dependencies. Most are also available as AAR artifacts in a CommonsWare repository, ready for inclusion in your Gradle-based project build scripts.
Android Background Processing with Handlers and AsyncTask and Loaders Android Background Processing with Handlers and AsyncTask and Loaders - Tutorial Copyright © 2011, 2012, 2013 Lars Vogel Android Threads, Handlers AsyncTask This tutorial describes the usage of Threads, Handlers and AsyncTask in your application. It also covers how to handle the application lifecycle together with threads. Creating a REST library using Retrofit & OkHttp I've been tasked to modernize our application's networking layer. We have been writing our own network manager to deal with http 302 redirect and caching responses, but there are many opensource project that already does these things very well. I've looked into RoboSpice and Volley as the more popular choices for doing networking in Android. I found that they're a good candidate as an improved AsyncTask as well as providing caching.
Saving (and Retrieving) Android Instance State - Part 1 - Intertech Blog Why do we need to save instance state? Android activities have a lifecycle (for a diagram of this lifecycle see here). As an activity becomes partially hidden (paused) or fully hidden (stopped), possibly even destroyed, your applications need a way to keep valuable state (i.e. data) the activity has obtained (probably from user input) or created even after the activity has gone away. As an example, an orientation change can cause your activity to be destroyed and removed from memory and then recreated again. Unless you avail yourself to certain state saving mechanisms, any data your activity has at the time of orientation change can be completely lost in this seemingly simple act. How do we save activity instance state?
