DynamoDB enum unmapping to immutable class - @DynamoDBTypeConvertedEnum I have an enum used in a Kotlin data class. Data class is a syntax sugar that ends up as an immutable Java class with some goodies. //@DynamoDBTypeConvertedEnum @DynamoDBTyped(DynamoDBMapperFieldModel.DynamoDBAttributeType.S) enum class Direction { INCOMING, OUTGOING, } Then I store an object of this class to AWS DynamoDB, using Java SDK 1.11.855. So far so good. Then I read it from the DB, but it fails, because the DynamoDbMapper can't find a setter (naturally - it's immutable class...

Android Navigation Structure Good day everyone! I am new to android studio so I'm still learning the ropes and best practises. I have an app (kotlin language) which makes use of a navigation bar + 3 Fragments. My question is: Should I continue the app working with only fragments? In this case I would probably have 10 different views to show. three views in each tab of the notification bar. So considering all the network calls I will need to do to read/write data to a database, is it better to use 1 activity with 10...

Hibernate mapping between Postgres array of varchar and a Java/Kotlin collection of enum Basically everything is in the title. I have a column in my DB which is a varchar[]. I really would like to map it to a Java/Kotlin enum. We've already got this working to fetch it as a list of Strings (through com.vladmihalcea:hibernate-types and StringArrayType), but not with a mapping to an enum. Do you know if this is possible? Since we know how to map a varchar to an enum, and a varchar[] to a collection of String, I would be tempted to think that this should possible, but I didn't...

Android 2d Game Kotlin - How to determine accurate hitbox Good evening everyone. I am developing a simple 2d game where you have to dodge enemies that come from different directions.

I was wondering if it was possible to determine a hitbox which is not a simple rectangle but which somehow could fit well with the image I am using. Currently all...

How to implement a Kotlin property through JNI? In Kotlin, I can use the external keyword to delegate the implementation of a function to native code. Given that Kotlin properties are mere syntactic sugar for a pair of getter and setter functions, I assumed that it should be possible to implement a property using native code, too. However, I can't seem to figure out why. If I prefix the get and set keywords with external, Kotlin tells me that it's expecting a function body: Of course, the whole point is not to have a function body in...

Kotlin - link two variables by Delegates, Annotation or? I get interesting idea, but I am not sure how to do it (if it is even possible - have some tips). Main use case: Variable of (data) class have reference to another variable. Be able at runtime get information about "linked" variable. Why? I am sick of writing dummy converters like: fun Foo.toMap() { return mapOf("var1" to this.var1") } Where constant keys are known. It would be nice to have this declaration attached to specific data class and then just use generic function to get map of it....

I've checked everything I can find and am now totally stumped, the only changes that were made was adding the onclicklisteners and intent for them. When undoing those exact changes, the...

The information has been gotten from the ContactsContract.Contacts table. This all works fine, so far. But now I have to edit the phone numbers of all the...

Kotlin method with generic return type I have a method that sits between a client and a server and it needs to return to the client ResponseEntity, with ? being a different class type based on the server's response.
