Talk: Static Code Analysis

by

Studies show that for every 7 to 10 lines of code we write, we introduce one defect. Now often times we can spot these errors before they ever see the light of day, however that is not true in all cases. So what can we use to assist us in leveling the playing field? Well, we can take advantage of Static Code Analysis tools!

Tools

  • Checkstyle
  • Lint
  • PMD
  • FindBugs

Conference: Android Summit 2015

by

This is how Android Summit started for me! A delightful dinner for the speakers where I had the chance to make some new friends; including the friendly conference committee lead by folks at Capital One.

The highlight of any conference is the keynote, and I was excited to learn all about becoming an Android “Expert” from Chiu-Ki Chan! She explained how we can use blog posts, public speaking, videos, and books to share our expertise and thus become “experts”.  

The conference consisted of two tracks: Development and Design. I decided to put on my design hat and attend a few sessions.  I really enjoyed the talks on prototyping with Pixate and thinking like an Animator.

 

After that I had to scurry off and present my talk on developing maintainable apps. I really loved the positive energy from the crowd and the head nods as I explained the annoyances of messy code:-(

Considering this is the first time the conference was held, I’d say it was a smash hit. I can’t wait to see what they have in store for us next year!

Talk: Developing Maintainable Apps

by

Great Android apps only include what’s needed to achieve the goals of the product, not enhance the resume of the developer. What’s more, the more maintainable an application is, the more likely it will have increased user satisfaction and decreased time to market.


So how can you do it?  Keep these four factors in mind:

  1. Choose your 3rd Party Components Wisely
  2. Keep your Code Simple
  3. Use Static Code Analysis Tools
  4. Write Unit Tests

Testing Your Apps with AWS Device Farm

by

Recently, I’ve been on a mission to enhance the quality of the tests in the Android applications that I work on.  To that end, I was introduced to the AWS Device Farm, a cloud based app testing platform.

It was very simple to set up and like most AWS products comes with free tier usage. You move through five steps (at most) and then your app will be tested on the devices you choose.  To get an idea of how it works, just follow the screenshots below.

1. Choose Your Application

2. Configure a test

3. Select Devices

Then you are presented with some additional device configuration options (bluetooth, NFC, GPS, etc.). Finally, you have the ability to review and submit your run configuration. Once all of the devices have completed running your tests you can then drill down and view the individual results of each test.
