Hello #Android #Kotlin #JetpackCompose enthusiasts 👋 I had been around earlier and then decided to leave. Turns out that may have been a bad idea 🙊 So, I decided to return.

Just in case.... It turns out that switching between Personal and Private not always redraws properly in Be nice 2.4.0. I am aware of the issue and it will be fixed when 2.4.1. codeberg.org/tkuenneth/be...

Be nice, my modern, slick, #OpenSource #Android launcher, now supports Private Space. Check out the clip below to see how it works. And, yes, work profiles are next. Get 2.4.0 on Codeberg or on Google Play (you need to join as a beta tester) codeberg.org/tkuenneth/be...

If you release frequent updates to your Android app (more than every 2 weeks), please set up robust baseline profile pipeline otherwise most of your users will have poor app performance (see developer.android.com/topic/perfor...)

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 ✨

Incredibly bold and necessary presentation by @ashdavies.dev at Droidcon Berlin. Thank you for speaking up so directly and honestly about the direction we're headed as an industry. www.youtube.com/watch?v=yR6j...

Thank you very much to all attendees of my talk about haptic devices on Android at @droidcon.bsky.social Lisbon #dclx26. You can find the sample code and the slides at codeberg.org/tkuenneth/st...

Excited to share that Be nice 2.3.2 now supports pinned shortcuts and therefore also can Receive links and PWAs from browsers codeberg.org/tkuenneth/be...

I was at @lisbondroidcon talking about what we did with the MAN Driver App and the use of KMP. I really hope everyone enjoyed it. 😊 #dclx26

Safe travels to all travelling today 🧳🛩️ #dclx26

In less than a day, will be on my way to @droidcon.bsky.social Lisbon. Can't wait to meet a lot of old friends. Join me for five things you did not know about vibrators

Now that Googlebook OS is out, I was checking how an app gets the "Optimized for Desktop" badge. It's definitely not an easy climb 😅 developer.android.com/docs/quality... #AndroidDev #GooglebookOS

We're looking for amazing talks to put into the KotlinConf 2027 agenda, with submissions open until Nov 27! You can find more info, plenty of inspiration, and everything else you need to submit a talk on the Speakers page:

Happy Monday @androiddevs.bsky.social! Need Material Expressive inspiration? Just ask Opus. Here are 10 beautiful, one-shot samples that I was able to generate over the last week with a directed design prompt (see Specifications section). m3e.c5inco.dev

Good morning everyone. It's day 3 of #NextAppCon #NextAppCon26 #dcbln26. Interested in a refreshingly #AI free talk about Android fundamentals? Join me at 11:20 in room droidcon 1

What if Kotlin testing required less boilerplate and more Kotlin? Oliver Okrongli and Bernd Prünster introduce TestBalloon, a new, extensible framework for modern testing patterns on every Kotlin target. Put it to the test: https://kotl.in/f6aokg

Safe travels to all travelling today #dcbln26

MarvinSync just got an update to look even better on macOS 27. As always, fully open source, no strings attached. Get it now on Codeberg: codeberg.org/tkuenneth/ma...

"Assuming macOS 27 is a deliberate exaggeration (since we are currently around macOS 17), ..." made my day

Started in 2014 with a simple idea: speakers need glanceable color cues, not busy clocks. 10+ years later, Min Time is still: 🟢 100% native Android 🟡 Modern platform APIs 🔴 Open source & tracker-free Play Store, F-Droid, Obtainium. Code on Codeberg: codeberg.org/tkuenneth/mi... #AndroidDev #FOSS

TIL you can get IntelliJ to sync project with later AGP version than it officially supports (e.g. one that Android Studio supports and is sometimes required for latest Compose etc) by setting following in idea.properties gradle.ide.support.future.agp.versions=true

📢 Quick Android CLI tips! [Install it: goo.gle/android-cli] Run `android update` often To install Android skills, run `android skills add --all` To regularly update them, run `android skills update --all` Or specify exactly which skill you want. That's all 😌

Literally can't wait to return to Berlin this year. Thrilled to once again be on stage at droidcon, this time talking about... 🥁 ... wake locks. Don't believe that's still a thing in 2026? By all means. Join me and let me explain 😎 #nextapp26

Google Play's rules for sensitive permissions like contacts and calendar access are getting stricter, squeezing small apps. This dev breaks down dangerous vs sensitive permissions using a real calendar app as case study. { author: @tkuenneth.dev } dev.to/tkuenneth/de...

Thank you very much @androidweekly.bsky.social for featuring my article "Android's AI Era: Hype vs. Architecture" in the latest issue of Android Weekly.

Latest Android Weekly Issue 744 is out! androidweekly.net/issues/issue... #AndroidDev #Kotlin

Android's "Intelligent System" pitch is three claims in one sentence. 1.5 years shipping against these APIs taught me which layer holds up (runtime), which is shaky (AppFunctions), and which is unverified (Halo, your agent). @dev.to dev.to/tkuenneth/an...

It likely is only me, but I got annoyed by the frequent changes in the Cursor (app) UI. Finally decided to go CLI only, and to also switch to @anthropic.com - boy, pretty pleased so far 😍

Such a great evening at GDG Korea Android! It was an honor to be able to speak to this community about AI tools and Android development. The slides for my talk are online at speakerdeck.com/danybony/the... #GDG #GDE #PublicSpeaking

Dangerous on the device. Sensitive in the store. Just published on @dev.to: Call Log, Contacts, then who may ship at all. Sensitive permissions were never only a Play Console form. They are a stress test for whether we use Android, or merely rent it. dev.to/tkuenneth/de...

Moni and I just returned from an absolutely gorgeous escape from the summer heat. We've been at the North Sea (Zandvoort, The Netherlands). Yes, we deliberately avoided the Grand Prix 🏎️ 🏁. 🔋 perfectly recharged, looking forward to do some coding now.

I mailed out jetc.dev Newsletter Issue #327! Compose stable release! Compose Material3 stable too! Liquid Glass in a multiplatform app! Preview generator! jetc.dev/issues/327 #JetpackCompose #AndroidDev

I'm open to work! People know me for my skills in Android, Kotlin, Compose, Gradle, Android Automotive, or for my hunger in eating issues for breakfast. You might also know me from my talks at @droidcon.bsky.social & @kotlinconf.com. Onward to new adventures! 🚀 I'm thankful for likes & reposts 🙏

Beyond excited to share that I'll have the honour of returning to droidcon Lisbon, talking about Five things you didn’t know about vibrators. Join me some cool stuff about haptic engines on Android, a strange piano, and some good vibrations.
