Want to Learn How to Program for Android? Start Here

Everyone has experienced the desire to program at one point or another. However, there are generally four limiting factors: Time Constraints, Study Material, Mental Blocks, and Attention Span. So clear your schedule, clear your mind, and self-medicate your ADD with a nice cup of your favorite coffee because here’s the material you need to learn how to program.

The hardest part of learning to program is overcoming a mental block. First, there is no programming deity out there who grants code-literacy to anyone. Learning to code is the same as learning any language—there are nouns, verbs, and sentences that come together in a certain way in order to make sense to the computer. Once you’ve written down a complete thought, the program works properly.

Second, even Java experts with PhDs in computer science think of Java as having huge black-boxes with inputs and outputs. Just as with any language, the higher your expertise means the more obscure language structures you can use. Anyone can learn basic language structures though.

The third mental block is to get motivated and “Just do it.” The tools are free.  The resources are available. Anyone who wants to write a program can do it and publish their work.  So you need to just jump right into your IDE and start making something.

Tools: How to Build an Android App Part 1: Setting up Eclipse and the Android SDKSetting up Eclipse and the Android SDK will give you the basic tools you need to get started making an Android app.  As with any project, you should start by gathering up your tools and learning to use them first.

Skills: “The Java Tutorials”The Java Tutorials is essentially an http E-Book that is laid out in the same format as many certifications and online courses. Many people have stated that they want to “Sit-down and learn Java.”  The Java Tutorials are a great way to do precisely this. This is tailored to writing generic Java applications, and not specifically Android’s implementation of Java. Learning this material will give you a strong knowledge base for programming Java applications.

Materials: Android “Package Index”The Android Package Index is a reference for all of the Packages, Classes, and APIs provided by Google.  Once you learn how to program in Java, you need to learn about the individual building blocks of an application. Each of these packages function as the nouns and verbs in your writing. The documentation show the appropriate time and place to use these words as well as what you get out of them. This package index serves as your dictionary.

Architecture: “Android Design”The Android Design page is a great launchpad for ideas in your Android application. This page is examples of what Google would like to see.  Each page shows design implementations recommended by Google.

The Human Aspect: Our Android hacking forum is the perfect place to ask questions, get answers, and see the works of other developers.

So, we’ve covered all the basics needed to get started creating your own Android applications. There are almost infinite resources available on the Internet. Please share your favourite resources below.

Open War for Open Android: Antitrust for Cyanogen?

Android and openness is something we talk about all the time, but the recent developments in the industry point towards inherent flaws with this very premise. Be it from bloggers, political institutions or corporations, Android is seemingly not open enough. The “War on Openness” is ironically becoming an open war, where many players are increasing their stakes and scope to try and land a bigger hold - or at the very least, restrict Google’s - on what is the world’s...

What Do You Do with All of Your Old Photos?

Smartphone cameras have advanced so tremendously over the past few years that they have almost completely replaced point and shoot digital cameras for the most of us. Furthermore, since our smartphones are always with us, the majority of us end up taking tons of photos throughout the lifespan of our devices. But what happens to all the old photos you take? Do you store them on an external hard-drive or keep them backed up to an online cloud service like Flickr? Let us know what your favorite way of storing old photos is and why.

Diving into the April 2015 Material Design Update

Before the release of Android 5.0 Lollipop, the Holo Design guidelines served as the official reference for Android design, right from IceCream Sandwich to KitKat. However, updates to the guidelines were few and far between, leading to a lack of synchronization between Android design and current UI/UX trends. Google seems to have learned from their mistake the last time around, and earlier this week, a significant update was released for the Material Design guidelines, marking the second revision in less...
