Have you ever run into the issue that the Run button in Android Studio loads an old version of the app onto the emulator? Sometimes after I change code, and click Run app, it loads a version with old code, before I made the changes, or EVEN earlier, before a lot more changes were made. Any way to fix this?

Edit configuration of the run config, clean build

I encountered something similar to what you have described. Whenever I cleared the app's cache then the app was reset to the oldest version. Still remember being confused in front of the client as the feature that was working suddenly didn't. I turned out it was what I have mentioned.

Thanks for the video! Another option for making the MyImage class stable is to replace the List type with a Kotlin immutable collection type, such as ImmutableList.

Thanks for the tips, I really appreciate them. On SwiftUI, scrolling appears to be smoother out of the box.

In the third example would the solution also be to make the collection as immutable list? Then the data class wouldn't contain any mutable properties and shouldn't be marked as unstable right?

@Philipp can you suggest me what is best way to use multiple state in composable screen.
@clamum96488 ай бұрын
Good stuff bruther. So I'm assuming my class could still be marked Immutable if it doesn't get its properties directly updated anywhere, but those underlying properties might be updated from the database? Like my list is a list of items that can be edited/updated in another screen, but the properties aren't directly updated anywhere in the list screen. If that makes sense.

Super video. However, if I have understood you correctly, @Immutable and @Stable cannot be applied to constantly changing lists. For example, if you load the data with a pager, can you only show a loading animation or is there also a way to improve performance and only recompose the newly loaded data and not the existing data in a lazy column?
@ggstb8 ай бұрын
Just make sure all the items in data class have val so when you are updating data you have to use copy function and you will be good to go and will be able to use Immutable and Stable without worries

When I debug the app using an emulator the app runs perfect, but if I debug it on my cell phone the app has a lot of lag. When I searched the internet, I found that changing the Build Variant from debug to release fixes it and it really works. Do you know why this could happen?
@boskovaskovic15 күн бұрын
There are a lot of debugable processes attached to the debug variant. However in the release version all those processes are gone.
