I am new to android development using kotlin, I have no problem implementing functions, but i dont know how to go about the UI, does kotlin has a framework for that like flutter or i am to build my UI using XML
Jetpack Compose launched recently which has a declarative approach for building the UI just like flutter. It works with Kotlin.
Check more about it here :) ( you don't need to use XML if you are using Jetpack Compose in your project )

I am new in Kmm I have create a UI with Jetpack compose for android and swift ui for IOS in simple application in kmm, so in shared module I just want to create viewModels for both android and iOS activities but I don't find any proper solution for this.
Had tried with this library to https://github.com/icerockdev/moko-mvvm
to achieve Clean MVVM in KMM project
eg: details about the questions ..i have a android app project using Kotlin. I want to make my Android application work on iOS using KMM.i haven't found any live solution yet. it would be great if you've any practical example to to make my Android application work on iOS using KMM?
there is no magic tool to do this ...
you can follow this steps ..
first you should convert java code to kotlin code by
Android Studio Menu -> Code -> Convert Java File to Kotlin File
then you should separate your code into business layer and presentation layer you can know about it by reading clean architecture Android
then we will put business layer into Shared Module
then we will put presentation layer into ANDROID APP
then application will be ready to use his business logic into ios
then you can write your swift code into IOS APP
note :
Presentation layer contain view , viewmodel and any Platform dependent tools like workmanger
business layer contain network and caching code like KTOR , SQLDELIGHT and any logic that may be shared between Android and Ios
I want to record a UI test in my jetpack compose project, just like record an Espresso test.
I want to follow thees steps:
start recording
open the application
click on the objects(buttons, etc...)
finish recording
get generated kotlin codes just like Espresso recording
It seems we cannot use Espresso in a jetpackCompose project.
but in this project I didn't completely migrate to JetpackCompose still. but It recognizes it as a Jetpack Compose project
Espresso testing framework cannot be used with Jetpack Compose so test recording is not yet available but Compose tests are fairly easy to write.
You can check the official documentation if this helps: https://developer.android.com/jetpack/compose/testing
I was using Rive to make animation for my flutter project, But now I'm wondering if there is a good substitution for Rive to use with kotlin (or something similar to that) in native android programming so i would be able to use awesome animations in native android too?
For native android animations you can use:
Lottie from airbnb -> https://github.com/airbnb/lottie-android
MotionLayout from google -> https://developer.android.com/training/constraint-layout/motionlayout/examples
Android Studio includes a visual design editor for the MotionLayout -> https://developer.android.com/studio/write/motion-editor
Doing a bit of searching I found that Rive has an integration with Android.
I don't know if it will be useful to you but I will still share the links.

I am working on a project where an old library is being used in Android natively. Because of this, I am forced to work in Kotlin and use a xml file in order to view some elements on the screen. However, I am questioning myself if there is a way to create a custom activity/fragment in Android and call a flutter screen file where I can use all the Flutter widgets within the app. I am currently using method channels in order to communicate between Kotlin and Dart and this is why I came up with this question. Any help is very much appreciated!
It is possible to launch an Android Activity in which Flutter engine will be able to display UI and perform any actions you want within a native Android application.
To do so, you need to create a Flutter module, here is the documentation.
