#compose-multiplatform when the app is opened, 4 components are launched and the ui is visible after 5 seconds, how to reduce this time?

[Arkadii Ivanov]

Can you provide more details? Is it a UI thread freeze? What causes the delay?

[UzMbApps]

when the app is opened for the first time, the white screen appears for 5 seconds, then the ui appears

I thought complex ui was in effect and I just created a simple ui to test it, it didn't help..

[Arkadii Ivanov]

Well, without a reproducer it's hard to help. Would it be possible to create one?

[UzMbApps]

ok i will create a retest app for you.

opens quickly in the emulator, hard to detect,
run it on a real device..

Applications opening speed:

DecomposeCounterApp: 1.2 seconds
MySlowOpeningTestApp: 2.6 seconds
MyRealProject: 4.7 seconds

Thanks! I think this slowness is related to Compose, as it needs time to warm-up. I tried running a release version of the reproducer and it opens much quicker. You can also try asking in #compose-android.

It doesn't look related to Decompose.
