OkHttp version 5.5.1 and 4.12.1 are now available and patches the compromised eMudhra certificates If you use OkHttp and support devices that do not have Google Play Services installed, you should upgrade ASAP github.com/lysine-dev/o... Again kudos to @swank.ca for the quick resolution ✨

I am really enjoying using Warp as my daily Terminal I never thought AI and the terminal would mix, but it's definitely helped improve so much of my workflow 🚀 Highly recommend giving it a try if you haven't already!

I've been losing my mind for the last few evenings trying to figure out how to write a KMP compatible Gzip decompression method JVM & Android were easy but iOS was driving me crazy with zlib C interop and alloc calls! TIL it turns out Okio can do it all, in two lines of code 😂

As many of you know, I wrote Modern Security in Android a couple of years ago. It's time for a well-deserved refresh It's time to talk about some new practices that you may want to follow It will be available at the same link this Sunday 👩🏻‍💻✨🥸🍊 medium.com/knowing-andr...

One of these Droidcon London featured speakers is not like the others 😂 (It's me, the others are Android legends)

One of the cool things I am *really* enjoying at work right now is being able to write both the backend and frontend mobile code for particular features It's made testing locally and the prototyping process so much faster 🚀
