I’m using

kotlin.Result

and trying to come up with a solution to backport it to java since it doesn’t really have good support. I have a simple Java class to kinda mimick the behavior, but

kotlin.Result

get’s double wrapped and throwing

ClassCastExceptions

. I’m wondering if I’m missing something or it’s just some weird bug. https://gist.github.com/igor-brishkoski/4df636445358f85ca40d22e02b4a9b2d

any idea on how to resolve these?

does anyone know if I should be able to use

kotlin-reflect

to see parameter names of java methods? the stubs in the IDE show the parameter names, so I assume they should be accessible in some way (?)

Hey I have json response coming from retrofit. I want to filter accordingly to

sentAt

property. I want to compare latest time and move block accordingly to that. Right now in my json there is 4 items/block but it could be more. Can some one know how to filter list and modify in efficient way. Also i need to convert

sentAt

value in time and date format and store in other variable. The format of todays date will be in

time

and if date is old i need in

date

format. Added Data class ConversationsResponse

data class ConversationsResponse(
    val conversations: List<Conversations>? = null
)

Conversations

data class Conversations(
    val id: String? = null,
    val title: String? = null,
    val lastMessage: LastMessage? = null
)

LastMessage

data class LastMessage(
    val id: String? = null,
    val text: String? = null,
    val sentAt: String? = null
)

Hello, I've a question. How can I use break keyword in LiveData observer?

for (i in 0 until domainList.size) {

    mainViewModel.fetchVbtopUrls(concatenated)
    mainViewModel.vbtopurl.observe(this, { it2 ->

        when (it2.status) {
            Status.SUCCESS -> {
              
                if (it2.data != null) {
                
                    break   //error
                }
            }

        }
    })
 
}

Hello, I've a question. I get that error if I use and the app crashes mainViewModel.fetchVbtopUrls(concatenated), but before it worked well. I can't understand the reason. I use Retrofit2, Coroutines, Hilt

Some of these guys get really pissed if it’s in the wrong channel, don’t know why, it’s not like we all started as pros.

I want to take first character from firstName and lastName. Also firstName and lastName may be null. I want to ask is there better way to approach this? firstName :

Vivek

or

Dr. Vivek

lastName

Modi

private fun getInitials(firstName: String?, lastName: String?): String {
    var initials = ""
    if (firstName != null && firstName.isNotEmpty()) {
        initials += firstName.take(1)
    }
    if (lastName != null && lastName.isNotEmpty()) {
        initials += lastName.take(1)
    }
    return initials
}

For example

Vivek Modi

output

VM

but when i enter

Dr. Vivek Modi

i want

VM

Is there any way to restrict possible type allowed? for example, i want to make a method that only accepts, Map<String, <String/Int/Bool>>, is there any way, i can restrict that? because using

Any

wont.

Hey guys I am working a an app that heavily relies on webviews, the problem is that there is a lot of jank. I tried to turn on hardware acceleration but it didn't help. What else can I do ?

When working with byte streams, do you think I get any benefit of working with

Byte/UByte

(unsigned types partial stable since v1.5) instead of

Int

? I deal most of the time with values in the range of 0-255. I'm also thinking about the architecture of the cpu (cpu natively works better with

Int

while there might be extra steps to convert from

Byte

to

Int

???) but tbh, I'm not so deep in this topic. This question might be a no brainer but anyway I'm curious about the pros and cons if there are any.

hi all. how to switch off in compose LazyColumn overscroll effect like android:overScrollMode="never" for RecyclerView

I have a client we're making their first Android app for. They made the account then took a ~10 months to get through contracting, and are now getting "Your count will be closed on Oct 13th unless you". We will not finish the app by Oct 13. Is there a good resource to figure out exactly how much we need to get their account configured to stop that notice? Also, is their account perhaps in a weird state when that happens, so they can't see "internal tested" apps? Google's documentation on this is super lightweight and it's not easy to see how to make this message go away.

I have noticed that some/many kotlin stdlib functions lack of escape, e.g.

repeat

. In the first place it's not clear what a

return@repeat

does. I would expect it leaves the iteration but instead it skips the iteration. AFAIK it's not possible to escape from

repeat

??!! And I guess the name does not implicitly tell that the repetition has to be finished. A

repeatUntil

counterpart would help here. Another example where a

return

is missleading:

map

,

mapValues

,

mapKeys

,

associateBy

,

associateWith

etc. Here I would expect that a

return

skips the current item, but instead the

return

gets part of data (

Unit

). Some

..NotNull

counterparts would help here. What do you guys think about that?
