I can't remember specifics right now, on mobile.

But I think the Kotlin classpath line needs to be in the module level build.gradle

And the plugin puts it in project level?

ah yes, I remember I had a similar issue once

thank you

why the keyword "when" is highlighted in blue?

@cesards:

Delegates.observable

is pretty useful. I would be sad if Kotlin were to remove it.

@maan: Nice post! Why did you choose to use xml in code? Why not go for the ANKO DSL? And some of the concepts of lattekit look like Android databinding, did you consider than?

Hey all, I have made a tool to quickly create a Android template project using Kotlin. Check this: https://github.com/nekocode/kotgo

is that the best idea for a sample app you could come up with?

thanks for the project though

Hi! Can you help me? At this

val intent = Intent(_context, AdvActivity::class.java)

i have error

Error:Execution failed for task ':app:compileDebugKotlin'. > Compilation error. See log for more details

does the log have more details?

Any1 having problems with kotlin modules and tests?

can you run gradle from the command line with —stacktrace? that might give you a little more info.

@kittinunf: I haven’t found any chance to try it on Android. Where and for what are you using the

Delegates.observable

. There is the

Delegates.vetoable

I don’t understand very well its purpose 😕

is that your code? AdvActivity and DrawerInterface?

@cesards: Let’s say you want a quick and simple way to update your Recyclerview. You could use

Deleagates.observable

as a way to get your job done. Example,

var items by Delegates.observable(listOf<Item>()) { meta, oldItems, newItems -> adapter.notifyDatasetChanged() }

Somewhere in your code

fun onUpdate(data: List<Item>) {
   items = data
}

Yes, it`s my code

public class AdvActivity extends AppCompatActivity implements DrawerInterface {...

DrawerInterface you can see at screen

DrawInterface isn’t visible outside of Drawer.java

Delegates.vetoable()

is a bit different. You need to return

Boolean

out of the lambda block to identify whether you want this type of change to go through. One caveat is the lambda for

vetoable()

will be called before the assignment which might or might not be want you expect.

sorry, i mean it’s not visible outside the package

all the java is slowing leaking from my brain simple smile

So, garethfleming thanks for time, i will try to fix it.

no problem. let us know when you sort it out.

Any idea why lazy is not working?

var tickets by lazy { LinearLayout(this)}
