Workmanager with Kotlin Multiplatform Mobile I want to call a method in from CommonMain periodically even when the app is in background. I wanted to start to implement it for Android, so I tried with Workmanager. But I realised that I cannot call any method from CommonMain inside the doWork() method. Is there a way to solve that issue? Or is there even a Workmanager Alternative for KMM to work with both iOS and android and being written inside CommonMain?

Problems making changes to the app with per-app language preferences I am currently implementing a code that I had in another application and that was working correctly, to make a language selector. The problem I have found is that when I follow the same steps, in my other app it works, but in the new one, it doesn't finish changing the language. When accessing the list of available languages, you press one of them, and the app freezes, it doesn't go back and you can't select another option either. If you exit and re-enter the app, you will see that the...

Idiomatic way to force AssertJ to compare by identity? AssertJ's assertThat(...).isEqualTo() method compares using .equals() by default. This is often the right choice, but sometimes you really do want to compare by exact object identity instead ("double equals" == in Java, "triple equals" === in Kotlin). Is there an idiomatic way to force AssertJ to do this kind of comparison, e.g. an assertion method for it that I don't know about? The best I've been able to do is work around it by doing the comparison without AssertJ, then merely using it to...

How to persist Preference objects using a custom data store instead of using SharedPreferences I have been working on a pet project where I initially used SharedPreferences to persist settings Preference objects. I decided to migrate it to use data store instead of SharedPreferences. So I started with the ListPreference for the dark theme configuration. It worked fine as expected but the ListPreference keep reverting to its default value (system_default_theme) whenever the theme configuration changes. For instance, when I select dark_theme from the ListPreference dialog, the app...

Override method of Type class (e.g String, Number ... ) in Kotlin? Overload operator on the Type class sound strange in practice but just on learning purpose, is that possible? String or Numberin Kotlin have build-in methods / operators as plus or + ... Is there any way to modify these build-in-s, because extension function can not override the build-in one. In Kotlinglang doc, Kotlin didn't have primitive type, all is Object means that it can be modified?

Kotlin Enum that is simultaneously a String I'd like to define a set of constants strings as a convenient enumeration for peace of mind on compile time. It feels obvious (with my Python background at least) that simple enumerations could be used as string instances. // Fine for overall use enum class Things{ FIRST, SECOND, THIRD } containsThings[Things.FIRST] // If a String is expected, this works but has extra stuff enum class Things(val v: String){ FIRST("FIRST"), SECOND("SECOND"), THIRD("THIRD") } // I want to get rid of ".v"...

Here is my code in Kotlin. : fun getApps(id: Long): Flux { val apps = mutableListOf() var app1Success = SuccessEnum.NOT_QUERIED...

WebFlux: How to retrieve AuthenticationPrincipal inside non-suspending @Controller methods I have a reactive coroutines based Spring Boot WebFlux application.
