Bit off topic, but can you download android-26 sources for IDE?

Is @Parcelize working fine with normal classes or data classes for you? @sliskicode

@sliskicode which version of kotlin are you using? I was using 1.1.4-2. Upgrading to 1.1.4-3 fixed my problem

@myanmarking for some reason I think Room solely works with Flowable… I could be wrong though. It’s the only thing I remember them mentioning at IO

How can I pass data from an alarm(broadcast receiver) to the ui? I'm looking at view models and live data, but I'm not sure how to update the viewmodel

do you have any problems? because I also wouldn’t think there are any. except the “problems” that were already there with 3.8.0 (enforced nullabilty)

Lint inspection Unused resources are not working correctly with Kotlin? 😞 If I run that Inspection it marks (it seems) every resource that I have

cb?.let {}

in andriod studio, give me error tip:

unresolved reference: let

. But I can build it successfully by gradle. I use kotlin in my old java project. Any body knows why?

There is kotlin compiler option: -Xno-check-impl Do not check presence of ‘impl’ modifier in multi-platform projects

This message was deleted.

Does anyone know why it fails to resolve it.

* What went wrong: Execution failed for task '👢transformClassesAndResourcesWithCustomProguardForRelease'.

java.io.IOException: java.lang.IllegalArgumentException: Stacks have different current sizes [1] and [0]

Hi, what’s best class to represent error in Android/Kotlin? Like NSError in mac/ios.

Hi folks, I understand that Java enums are not great to use in android development, due to performance and memory overhead. Are kotlin enums any better? or just the same?

Yeah, i use them for objects, but in my case, i think I’ll stick with Ints

#gradle might be more suitable for that question.

i have module A with

class X

in it, and module B which depends on A, and

class Y : X()

in AS, everything looks fine, and i can click through on X in Y’s declaration to open up X. however, when i build (thourgh AS or command line), it says X cannot be found. this only happens with kotlin classes

hello, does anybody know hot to get rid off unused methods in listener like at example below?

tab_layout.addOnTabSelectedListener(object : TabLayout.OnTabSelectedListener {
            
            override fun onTabSelected(tab: TabLayout.Tab) {
                pager.currentItem = tab.position
            }

            override fun onTabUnselected(tab: TabLayout.Tab) {
                //unused
            }

            override fun onTabReselected(tab: TabLayout.Tab) {
                //unused
            }
        })

What do you think is the best solution for a network SDK?

Am curious i never learnt rxjava i didnt really see the use or maybe i was naive but now with kotlin and architecture components is there really a point to learning rxjava?

hey does anyone know how good parcelize library works with kotlin?

@rkeazor Thanks for your reply and suggestions! I thought about implementing what you propose first but with databinding: - the list_fragment.xml RecyclerView layout with

android:visibility="@{adapter.itemCount > 0}

- a list_empty.xml layout with

android:visibility="@{adapter.itemCount == 0}

The issue is that I have trouble linking the

adapter

variable to the xmls 😕

@agrosner Right, I didn't notice that, thanks for pointing it out! Is there a way I can achieve what I have in mind with databinding?

@{condition ? View.GONE : View.VISIBLE}

can you do multiple method calls inside the lparams block or does the api depend on the return of the contained expression? also center in parent looks to override align parent right. wouldn’t it be vertical center in parent?

I'm writing Kotlin code, but I would like to see how it would look like in Java to see how much lines I'm saving.

You definitely don't want to use the IDE generator since it doesn't maintain the code for you
