Mark Murphy is the founder of CommonsWare and will serve as the trainer for your seminars. Mark has delivered Android application development training since 2009, and to date has trained well over 1,000 developers in how to write Android apps.

As a leading expert in Android, Mark has not only delivered countless training classes, but has also presented at dozens of conferences, meetups, and similar events. And, along the way, he has contributed countless hours helping developers overcome challenges in their day-to-day Android work.

Oh, and he wrote some books.

First published in June 2008, The Busy Coder's Guide to Android Development was continually edited and extended over the years. At over 4,200 pages, the book is easily the single largest compendium of Android app development knoweldge. It focused on first-generation Android app development, using Java and the Android Support library.

Mark has moved onto books on second-generation Android app development, using Kotlin and the Jetpack libraries and tools. These books include Elements of Android Jetpack and Exploring Android.

Every attendee of the training receives a Warescription, entitling the attendee to a copy of CommonsWare's roster of books, six months of updates, and access to subscriber-only office hours.

Mark delivers conference presentations every year. He is a regular at conferences in the mid-Atlantic area of the US, such as the Android Summit. He occasionally presents outside of that area, and also delivers some presentations to meetups by remote.

Occasionally, a conference publishes videos of Mark speaking — this page aggregates a number of those videos.

To date, Mark Murphy has answered over 21,000 questions related to Android app development on Stack Overflow. His reputation has him inside the top 10 Stack Overflow contributors worldwide, across all subjects.

Mark Murphy is many things. He is not a social media maven.

That being said, Mark has a long-running blog on Android app development and posts occasionally on Twitter.
