How to properly show progress of async tasks used by Google Room I'm using Google Room to implement persistence of data in my Android app (Kotlin code). Room demands all the operations (queries to and from the database) to be async. I would like the user to wait for the operation to execute, preventing him from interacting with components that would not be configured properly before the end of the query. How can I achieve this, since I can't access the UI thread from a async task? PS: I also do some calls to an API where the progress/loading indicator...

Can I access the "enclosing" object for an inlined function call in Kotlin? Idea: Make an inlined convenience function to synchronize a function call on the "inlining" object's intrinsic lock: public inline fun intrinsicSync(block: () -> T): T { return synchronized(intrinsicLockOfTheObjectUsingTheFunction) { block() } } fun someFunction(parameter: SomeClass) { intrinsicSync(sharedResource.operation(parameter)) } Is this possible? If not, is there a different but equally convenient way? I concede that fun someFunction(parameter: SomeClass) {...

Suppress Dokka complaints about "No documentation for com.foo.Bar$toString()"? I'm using the Gradle Dokka plugin version 0.9.16-eap-1 to generate documentation for some Kotlin code. I'm a no broken windows kind of person and consequently a bit frustrated that the plugin generates a tonne of messages for classes for which I haven't explicitly documented an overridden method which is adequately documented in the base class, eg: package com.foo /** * A silly class to demonstrate silliness. */ class Bar : java.io.InputStream() { override fun read() = -1 override...

Vertx Sync code runs multiple times I am writing a web service project using Vertx web and verticles with Kotlin language. When I try to switch to Vertx Sync to stop getting into callback hell, some parts of my code run more than once without a reason. When using old callback structure there is no such problem. This is some sample code: router.post("/layers").handler(fiberHandler { routingContext -> val request = routingContext.request() val response = request.response()...

Is there any way to iterate all fields of a data class without using reflection? I know an alternative of reflection which is using javassist, but using javassist is a little bit complex. And because of lambda or some other features in koltin, the javassist doesn't work well sometimes. So is there any other way to iterate all fields of a data class without using reflection. (I'm not a native English speaker. if there are any mistakes between words, please ignore them)

Kotlin data classes contains open functions I was reading kotlin official tutorial, Under the data class topic, I came up with a following point. If a supertype has the componentN() functions that are open and return compatible types, the corresponding functions are generated for the data class and override those of the supertype. If the functions of the supertype cannot be overridden due to incompatible signatures or being final, an...
