Pascal went mobile again and brought the mics to this year’s droidcon Android conference in London. He interviewed the record-breaking six speakers Facebook had this year and discussed some topics with them. This episode kicks off with Sergey, who presented a deep-dive into the current state of cross-platform coroutine libraries for Kotlin, comparing Reaktive and kotlinx.coroutines Flow in their usability, performance and memory appetite. The second interview is with Alexander from the Fresco team who talks about the evolution of the open source image loading and memory management library and teases at what’s up next for the widely used project. In the last interview we hear from Lisa (https://twitter.com/lisawrayz), a software engineer on the Messenger Lite team. She joins Pascal to chat about the design principles that went into designing a messenger application for emerging markets. Sadly, the video recordings of the talks are currently unavailable, but we will update you here and on the podcast as soon as that changes. Please do send us feedback!
