Three years ago, David Sumler was driving a car without a hood on it.
“Some lady ran a stop sign and hit me, and I didn’t have the money to fix the car, so I drove it without a hood,” he says. “I’d park as far back as I could in parking lots when meeting friends, so they didn’t see it.”
But that wasn’t the worst of it.
“I was buried in debt,” says David, 32. “I could barely keep up with my bills and I couldn’t buy nice things for my kids or my fiancée. I had no health insurance so I just never went to the doctor. If one disaster had happened, I would have been on the streets—and I came very close a few times.”
Then opportunity knocked.

I was recently asked about how to set up a local Android development environment correctly, and it was such a good question that I wanted to share the answer with everyone.
Q: I’m learning how to create Android apps. In Eclipse with Android Developer Tools, when I create a new app I get a null pointer exception right away. I’ve also noticed that the new project’s “src” folder, where my Java source files should be located, is empty. What did I do wrong?

Technology moves so quickly, it can be hard to keep up—particularly when developer tools change after we’ve recorded a course.
I recently heard from a member who was trying to work through my course Building a Note-Taking App for Android and having trouble running and testing his code.

You don’t have to be a developer to get excited about the announcements to come out of the Google I/O last week. Though the conference is geared toward developers, Google I/O is the place to get a first look at future updates to the Android platform, Google Play store, Chromebook OS, and other fun gadgets.
At lynda.com, we’re excited to get our hands on the new tech—to collect all the information we can and distill it down to great training. Let’s take a look at conference high points to get an idea of what’s coming from Google.

Learn more about Facebook Messenger 3.0
Facebook has just released an update to its standalone messaging app, and the changes are significant. The app has been completely redesigned for both iOS and Android platforms and boasts many aesthetic and functionality changes as well.
Aside from the new look, the biggest change is the ability to message people who aren’t among your Facebook friends. This is contingent on whether you allow the app to access your phone number and/or contacts list; if you allow it, others will be able to message you directly, regardless of whether they are on your list of friends, and you’ll be able to do the same.

Creating an app for Android, iOS, or Windows means learning two things: a programming language and the SDK. Even if you use one of the cross-platform frameworks, you’ll still need to learn some peculiarities of each system. It requires a significant investment in time and talents—and you’ll have to repeat it to create the same app for a different phone.
lynda.com can help with this learning curve. We’ve created a playlist of three new parallel courses: Building a Note-Taking App for Android, Building a Note-Taking App for iOS, and Building a Note-Taking App for Windows Phone 8 and Windows Store. Together they provide a roadmap for building a cross-platform mobile app.
We’ve built the same app for all three mobile platforms (actually four; Windows Store and Windows Phone are separate), using the same assets and creating the same functionality for each. We enlisted three top-notch authors to show you how they would implement the application on each platform. Our authors shared outlines and met regularly to coordinate their efforts, only making changes when the particular language or SDK demanded it.
To use this set of courses most effectively, start with the platform you know best and review how that author chose to implement the app for your favored SDK and language. Then choose your next device and watch the related course. Feel free to switch back and forth between the two, comparing the platform you know to the platform you’re learning.
Our authors provide you with insights to each platform, pointing out differences that may trip you up if you’re making assumptions based on a different SDK. In the end, you should be able to map your experience from one device to another.
Please be sure to fill out the survey at the end of each course. We’ll read your comments to see how we’re doing and how we can improve.
