What will be the relation between Android KTX and Anko ? Will they complement each other, or am I missing something and they will have different goals inside the Android platform ?

Hey guys, I am having an issue with my kotlin library project. when I export the project as

aar

and compile it to a project that kotlin is not added to and having the exception

Caused by: java.lang.ClassNotFoundException: Didn't find class "kotlin.jvm.internal.Lambda"

What could be the problem?

Then Log.d("tag", "${activityNullable.getClazz()}) should work

question about nullable types - as an example, let's say I have a util method in java with signature:

public static void showDialog(@NonNull FragmentActivity activity)

and I call it within a fragment using kotlin as

Util.showDialog(fragment.activity)

. The compiler complains that

Expected: FragmentActivity, Found: FragmentActivity?

Knowing that the activity will not be null when I call the method (i:e I call it right after

onActivityCreated()

), which of the following would be a good way to handle the error: - casting:

fragment.activity as FragmentActivity

- non null assertion:

fragment.activity!!

-

let/if

blocks (but this will hide the exception and hurt me in the long run)

I have a string which holds a json response. How Can I convert or cast it into JsonObject in Kotlin? var string : String = "{\n" + " \"success\": true,\n" + " \"response\": {\n" + " \"message\": \"Login is valid.\"\n" + " }\n" + "}"

hello I'm a new member in this group.I do J2E and android with java.I want to know how to become a good developer of Kotlin ?

does anyone recommend a logging library? is there anything kotlin-specific or should I just use timber ?

if only https://github.com/square/moshi/issues/309 was fixed

Has anybody noticed a

Error:(67, 25) Unresolved reference: context

while using kotlin and databinding ?

Couldn't find anything about this on the web but does anyone use Travis CI to build their apps? Trying to figure out how the support for Kotlin on Travis is

I don't like to use fragments because of its lifecycle, I already had many problems with it

Yes, I have cleared and rebuilt it

I give App class name to android:name, but it is not working

I’ve trying to ensure that all traffic goes over a particular network. The problem is that for some reason

setProcessDefaultNetwork(...)

is missing. Am I missing an SDK or something? I’m thinking this may be a Kotlin issue, but I’m not sure.

if (isEnabled && Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    connectivityManager.bindProcessToNetwork(network)
} else {
    connectivityManager.setProcessDefaultNetwork(network)
}

Anybody get

in espresso tests? Maybe I have something wrong here?

@RunWith(AndroidJUnit4::class)
class NewWazeTest {
	@get:Rule
	val rule = ActivityTestRule<FirstLoginActivity>(FirstLoginActivity::class.java)

	@get:Rule
	val intentsTestRule = IntentsTestRule<CheckServerActivity>(CheckServerActivity::class.java)

Hi, has anyone tried to mock extension functions with mockito? Internally extension functions are converted to static methods so mockito cannot mock these. Then there is possibly PowerMock or we can provide an interface where the class that implements it, has a method wrapping the call to the extension function. Any suggestions?

Ah ok. So far I have been testing extension functions using assert to verify expected and actual results. However, since on the surface, extensions look like methods of the class being extended, there may be scenarios where you would want a way of mocking that function if that class is being injected as a dependency

that's a very apt comparison in this case seeing as all of the core libraries for iOS are written in Objective C and have no sign of going away any time soon

I don't think/hope Java is not going away anytime soon. Java is a strength not a weakness

doh. slowpoke to the ktx questions

Hey guys, when you use

kotlin-android-extensions

, how do you name view IDs

lowercase_underscored

or

camelCased

?

my thoughts are encapsulated here: https://publicobject.com/2016/01/20/strict-naming-conventions-are-a-liability/

A rather serious question regarding android instrumentation testing and kotlin: Is there a way in sight to mock kotlin classes in android ui tests? Using Dexopener and the AllOpen plugin feels.. kind of hacky and not very 'native'.

forced to write new app with java... 😭

the code I'm using right now is this:

with(AnkoContext.create(parent.context)) { ...layout... }

but that doesn't allow me to set layout params for example

Hello, i am trying to design a basic API module for an android app, i’m having issues trying to design the class relation (trying to use generics) Its there any guide or resource i can use for best practices when doing this kind of stuff? Thanks in advance

I have used it a couple of times for creating some small views from code, never big layouts

Still getting

Test running failed: Instrumentation run failed due to 'java.lang.IllegalAccessError'. Empty test suite.

running espresso tests w/ Multidex on... anybody encountered this...?
