On my Android phone: half the time pw fields aren't recognized so I gotta go to launcher, start 1P, unlock by fingerprint, try again, try again, fail input passcode instead, lookup by app name, copy, app switch back, paste.

Cognitive.. shift loading?

Mardi 21 Octobre (dans 2 semaines!) à 19h, le Paris Android User Group organise un meetup chez Radio France. Il paraît que le lieu est magnifique!

Je serai là en 2e partie pour vous parler de benchmarks dignes de confiance.

#AndroidDev #paris

Talk 2. Des benchmarks dignes de confiance
👱‍♂️ Pierre-Yves Ricau

Jetpack Macrobenchmark, à première vue ça paraît assez simple: j'écris un scénario de test, je fais tourner le benchmark avant et après une optimisation, et hop, 20% d'amélioration de la médiane, je prends la confiance et je file demander une augmentation ! Hélas, un collègue a la mauvaise idée de relancer le même benchmark et obtient seulement 15% d'amélioration. Qui a raison, quel résultat communiquer?

L'objectif de cette présentation est de vous apprendre à creuser au-delà du résultat d'un benchmark, obtenir une meilleure appréhension de ce que vous avez vraiment mesuré, et saupoudrer le tout d'un peu de stats pour avoir l'air intelligent en soirée.

A great talk by @p-y.wtf @ DroidCon on "Embracing the Chaos: Investigating Production Madness".

I couldn't agree more that a lot of growth as a software engineer is all about understanding the root cause. So much of my Grade, JVM and other knowledge came from that.

Generating drawing commands and executing them later also falls in that pattern right?

A few of us were asked for our thoughts on the future of Android at @droidcon.bsky.social Berlin.

As you'd expect, lots of AI mentioned.

I tried to have a slightly different take, and sneaked in Remote Compose as a potentiel way for chat to add App UI

I don't think we ever wrote about that, I never looked into the details but app updates is relatively simple IIRC: download an APK, then, assuming you've got the right system permissions, fire an intent?

OS update is something else, I think you download to another partition then reboot there?

Last week at Droidcon Berlin I talked about some of the wildest Android bugs I've seen

Have you ever debugged a device using a hairdryer?

Not the sale scale, but Friday my flight from Berlin had significant delays in part due to a cyberattack Monday (5 days before!). All boarding check ins were manual, and of course the in plane count didn't match the check in count.. 🫩

We already had incremental compilation in the single-digit seconds range, but I’m still blown away by how much faster it is now that the entire codebase is fully on Metro. 🤯

Heard in a standup:

"So yesterday I wasted a bunch of tokens trying to solve this problem, but got nowhere with it. Moving on to something else, it's just not worth spending more time and tokens on."

Goodbye Droidcon Berlin! That was a blast. Now I need to rest for a 1000 years.
