If you want to contribute to opensource, it always helps to look inwards. Dependencies in your projects might have small bugs affecting your app, which are fixable by your team.

Over the past year, our mobile team has been building blazing fast charts with realtime updates on our android app which is available to everyone now. If you want to nerd out on technical details(hint: canvas.draw) check out the blog by the team!

opentelemetry android is going api stable!
this unlocks a well proven observability stack for android applications, not to mention the same data format which can be plugged into existing ingestion and visualisation providers!

Android provides great inbuilt tracing capabilities which can be visualised with perfetto. However traces are complicated to look at from layman's perspective but they are queryable using perfetto sql, a lightweight wrapper on top of sql schema.

Running asynchronous tasks in apps is more complex in terms of performance and agility than APIs suggest. In my latest blog, I examine results of async execution, exploring the interplay of concurrency and parallelism, with insights on Kotlin coroutines.

duality of vibe coding
with newer tech -> wow so much knowledge and code at finger tips
with tech you're proficient in -> this is absolute garbage
engineering prompts is the next frontier for the latter.

Android Studio now offers free 30-minute device streaming from various manufacturers for testing across different OEMs.
Great for individual use but many OEM labs are in regions like China and South Korea, requiring GCP project approval, complicating enterprise use 😐

Recently prototyped Cloudflare Workers using Kotlin and KMP to power both Android/iOS apps and edge functions + AI inference on Cloudflare's network.
Key wins:
- Shared HTTP clients & serialization
- Consistent request/response models
- Type safety everywhere

Agentic AIs are goldmine of productivity. I used claude code to do updates to my personal website which I haven't touched for 4 years or so and always procrastinated to do so. Best way to work is with a feedback loop to avoid tech debt. Exciting times!

One day, perhaps mobile teams won't over-index on crashes being the end all be all of production problems and try looking for the insidious, frustrating perf problems that aren't so obvious, the silent killers that cause churn in the darkness.
Unfortunately, that day is not today.

Did you know that you can troubleshoot FCM directly on any Android phone?
From the Google Dialer, dial *#*#426#*#* to open the FCM Diagnostics page.
It has a page with connection status and a page with recent events.
