Episode 156: Android Runtime Classic (Dalvik)

Feb 20, 2021


It's history time! Or even [pre-]ART History time!
We didn't take a picture this time.
Please imagine what we looked like.

This time, Tor, Romain, and Chet were joined by Dan Bornstein, one of the early members of the Android team. Dan joined in 2005 to create a runtime for Android, which became Dalvik.

We talked about some of the early placeholder VMs used while Dalvik was coming online, some of the design decisions for Dalvik (like its register-based vs. stack-based implementation), and nice techy details about runtimes, garbage collectors, and optimizations.
