I am going to assume by this statement that you've never worked on an Android project before. I work for an enterprise company with lots of Android apps and fragmentation is very much real.

The HTC Desire and Samsung Galaxy S3 are both very popular and still being sold today. It is extremely difficult (borderline impossible) to make one decent app run on both. You have to build two apps.
