How to analyze and improve performance of your Jetpack Compose app

Help your Jetpack Compose app run smoothly by reading system traces with Perfetto to find slow parts of your UI and recognize sub-compositions, recompositions, heavy compositions, and more. We'll also share how to discover and fix common lag causes using tools, not rules, to fix, and validate issues with benchmarks.

Thank you for great example on how we can use trace, microbenchmark and Perfetto to find sluggish parts. Great jobs!

I wish more videos on I/O were so helpful as this video

[GakisStylianos]

What an information dense video. Thanks for making it!

[abdonasr]

great workshop ⭐ we need more ones like these on other topics.

I love Android development, it challenge me to learn every day new stuffs

[kushiskinng]

wont' the box scope be the nearest scope for the recomposition? Am I missing something?

[suleimenovsultan]

interesting that pguys used they macbook for android development and stickered apple icon on it :)

ps I am android dev with macbook too, waiting for similiar fast and silent device to use

Ok, where do I get that sticker of a duck with Android hat - asking important questions here

[SnoopyDoofie]

You are seriously requiring developers to upload a trace file to a website to check for performance?? My gosh, the Android team is really out of touch.
