but having a notificationManager extension property on a Context object, which under the hood does the getSystemService song and dance, wouldn't be so bad I suppose

Hi guys, silly question... If I'm using

something?.let{}

there is a fallback delegate for the case of the item be null? Or in this case I should write a null check?

Is sharing libraries you made frowned upon here. Would love some feedback!

@spirosoik worked fine on our system, we also implemented Deteck for Kotlin static analysis

But if I see one more "advanced mastery" course that only goes up to lambdas and higher order functions I think I'm going to scream

If you can get the job done using Java, there is really no reason to force a switch. We switched because the features really helps us as a developer to save time and effort

Sure I had the same doubts initially, but I confess I switched most because of hype and because I found very pleasant to writing Kotlin code 🙈

Do people typically share their Live Templates? I've been looking around and haven't found any for download and it seems like it would be one of the best things to share for people at all levels.

Would it be ok to register greenrobot EventBus in android architecture ViewModel and unregister it in onCleared()?

Speaking of json serialization, which one would you recommend for kotlin? Moshi, Jackson, Gson or something else?

I was wondering, how much do you guys use XML in code? I'm still learning, so I'm not sure if it's better kept to a minimum with help of libraries like anko

Not sure if this is the right place to ask but what is this error?

Error:Execution failed for task ':app:javaPreCompileDebug'.
> Annotation processors must be explicitly declared now.  The following dependencies on the compile classpath are found to contain annotation processor.  Please add them to the annotationProcessor configuration.
    - butterknife-7.0.1.jar (com.jakewharton:butterknife:7.0.1)
  Alternatively, set android.defaultConfig.javaCompileOptions.annotationProcessorOptions.includeCompileClasspath = true to continue with previous behavior.  Note that this option is deprecated and will be removed in the future.

Hi, is there any known bug that calling kotlinMap.forEach causes proguard to create a warning like

MyClass$myMethod$1$1$1: can't find referenced class MyClass$myMethod$1$1

what’s the suggested test framework to use for kotlin based android app

wonder how well does it scale when mocking final classes in a big test suite ?

koufa

Or how to you handle the

lifecycle

with

coroutines

? How do you avoid leaking an

activity

? Is

job.cancel()

onDestroy

enough to avoid memory leaks?

alex.tavella

imo, stop using butterknife. Use lazy properties instead.

Android extentions useful only if you have short, while still unique ids. It is not the case for big apps with many complex UI elements.

alex.tavella

11/26/2017, 11:09 PM

The problem I see with lateinit is that your property is not immutable, I still prefer to use lazy delegate with no thread safety argument

dekans

11/27/2017, 9:08 AM

@alex.tavella I doesn't work in fragments. Views are destroyed and re-inflated on rotation, but fragment (and its references) persists, so you leak old views refs and can't update the new ones

Anil Sisodiya

11/27/2017, 12:59 PM

@adam-mcneilly I think you should use these extension once view created in fragement

Any1 successfully using

with proguard?

david.bilik

11/27/2017, 1:20 PM

@simon.vergauwen Nope, I must`ve added this to proguard rules

# Parcelize shit
# workaround for jenkins to build app, for unknown reason, Parcelize is not working

this is not really Kotlin-specific but did anyone manage to get the new Pixel2 images into AS3? supposedly they were in 26.0.2 but I am not seeing them...

if you dig into the pure cli tools you will find that they don't actually install any skins. AS does something odd to facilitate all the pretty options. also if you create an AVD from the CLI it is unusable without modifying the resulting ini config

weird

but the other dev on the team has it!

she sent me a screenshot and there are the 2 Pixel2 devices in the AVD manager..
