The reason of lagging, lack of smoothness in search & home view

[Nephys222]

Of course it would not be identical to Spotify but with this beautifully written with latest Android libraries lacks smoothness home & search fragments. Is this the cause of Jetpack Compose or about acquiring data from Spotify API?

Help & answer would really appreciated!

Hey there. If you're talking about the demo video of the app, then the lag is because of the emulator and not the actual app. If you're referring to the app itself, then I'm not sure.
It might be because of the device that you tried to run it on, or, it might be because of some performance related mistake that I might've made.

@t3chkid Thanks for your reply! I did test on Android 7.0 Nougat. The issues were on it. Are you planning to maintain the app and accept PRs or it is one-time project?

Unfortunately it's a one time project of mine and I've stopped development of the project a while back. But I'm still curious on what might be causing the performance issue. Would you mind specifying the device on which you actually tested it on?

@t3chkid Of course. It is at HTC One M9 Android 7.0. Also tested on Redmi 10C Android 12. It is more smoother on it. Here is video from HTC One M9.

At home there is some view anchoring issue

Thanks for that detailed reply with very useful screen recordings. Yea, I think there's some issue with how the filter chips row react to scrolling in the Home Screen. I'll definitely try to fix that.

Regarding the lag, it's a HTC One M9, a phone released in 2015. Ofc it's gonna lag at times. So, I don't think performance is an issue.

I know it's been a while, but the lag that you might be facing might be cause because of the fact that you might be running the debug version of the app. As you probably know, compose might have some performance issues in debug mode. Build the app in release mode and try again. I tried it out and I definitely found the app to be much more snappy.
